The technical solution of this application is primarily applicable to indoor locations such as supermarkets, shopping malls, and warehouses where large quantities of items are stored. These locations often feature numerous shelves, each comprised of multiple layers of supports, upon which items are placed. The shelf objects described in the embodiments of this application may refer to items placed on the shelves.

Because the prior art requires manual measurement and mapping of items on each shelf shelf, the operation is very cumbersome. To address the technical problems of cumbersome, inefficient, and inaccurate map drawing in the prior art, the inventors, after a series of studies, proposed the technical solution of this application. The embodiment of this application provides a map generation system, which is composed of a server, a mobile terminal, and a monitoring terminal, wherein the monitoring terminal is arranged at a preset position in an indoor location and has a known location. The mobile terminal is used to transmit wireless signals and process shelf objects on the shelf to obtain object processing information; the object processing information is sent to the server; the monitoring terminal can receive the wireless signals and send the wireless signals or the distance from the mobile terminal to the server; the server can determine the shelf object processed by the mobile terminal based on the object processing information; the server can locate the processing position of the mobile terminal when processing the shelf object based on the wireless signal, and use the processing position as the object position of the shelf object; thus, a map can be generated based on the object position of the shelf object. The embodiment of this application realizes the automatic generation of maps without manual drawing, thereby improving the accuracy of maps.

The technical solution of this application will be described in detail below with reference to the accompanying drawings.

Figure 1 is a schematic diagram of the structure of an embodiment of a map generation system provided by the present application. The system may include a server 101, a mobile terminal 102, and a monitoring terminal 103;

The monitoring terminal 103 is arranged at a preset position in an indoor place. Optionally, the monitoring terminal 103 can be specifically arranged on the ceiling of the indoor place, and its position is known.

The mobile terminal 102 can transmit wireless signals, and the monitoring terminal 103 can receive the wireless signals transmitted by the mobile terminal 102. There can be multiple monitoring terminals 103 to ensure that wireless signals transmitted by the mobile terminal 102 at any location in the indoor place can be received by a monitoring terminal.

Specifically:

The mobile terminal 102 is used to transmit wireless signals; process shelf objects in the shelf to obtain object processing information; and send the object processing information to the server;

The monitoring terminal 103 is used to receive the wireless signal and send the wireless signal to the service terminal 101;

The server 101 is used to determine the shelf object processed by the mobile terminal 102 based on the object processing information; locate the processing position of the mobile terminal based on the wireless signal emitted when the mobile terminal 102 processes the shelf object and the position of the corresponding monitoring terminal; use the processing position as the object position of the shelf object; and generate a map based on the object position of the shelf object.

The wireless signal emitted by the mobile terminal 102 when processing the shelf object is forwarded to the service end by the corresponding monitoring end.

Among them, the mobile terminal can continuously transmit wireless signals at a higher frequency, and the monitoring end continuously receives the wireless signals and reports them to the service end, ensuring that the wireless signals emitted by the mobile terminal when processing shelf objects can be obtained.

The corresponding monitoring end when the mobile terminal processes the shelf object may refer to a monitoring end that receives a wireless signal transmitted by the mobile terminal when processing the shelf object, and the corresponding monitoring end forwards the received wireless signal to the service end.

Therefore, the server can specifically locate and obtain the processing position of the mobile terminal based on the wireless signal emitted when the mobile terminal processes the shelf object and the position of the monitoring terminal that receives the wireless signal emitted when the mobile terminal processes the shelf object.

The object processing information sent by the mobile terminal may also include the processing time, and the wireless signal sent by the monitoring terminal may also include the reception time. Therefore, optionally, the wireless signal corresponding to when the mobile terminal processes the shelf object can be determined based on the processing time and the reception time of the wireless signal. A wireless signal corresponding to a reception time that is consistent with the processing time or has an error within a preset range can be found, and this can be used as the wireless signal corresponding to when the mobile terminal processes the shelf object. The monitoring terminal corresponding to when the mobile terminal processes the shelf object can be a monitoring terminal whose reception time is consistent with the processing time or has an error within a preset range.

There may be multiple monitoring terminals that receive wireless signals transmitted by the mobile terminal when processing a shelf object. The closer the monitoring terminal is to the mobile terminal, the greater the signal strength of the received wireless signal. Therefore, to improve calculation accuracy, the corresponding monitoring terminals when the mobile terminal processes the shelf object can optionally be the corresponding monitoring terminals determined in descending order of signal strength of the received wireless signal.

In the embodiment of the present application, the wireless signal may specifically be a high-frequency signal, and optionally, may be a high-frequency, ultra-wideband, and low-power consumption signal.

In order to facilitate indoor positioning, the wireless signal can be a short-range wireless communication signal. The monitoring terminal is arranged in an indoor place. When the mobile terminal is located in the indoor place, it can ensure the transmission of wireless signals with the monitoring terminal.

The mobile terminal may be equipped with a transmitting component for transmitting wireless signals. In one possible implementation, the transmitting component may be a UWB (Ultra Wideband) chip, the monitoring terminal may be a UWB base station, and the wireless signal may be a UWB signal.

UWB is a wireless carrier communication technology. UWB signals are transmitted in pulses. Since it is ultra-wideband, it can be transmitted continuously, with fast transmission speed and calculation speed. It can ensure positioning accuracy and improve positioning efficiency, thereby improving map drawing efficiency and accuracy.

Of course, the transmitting component may also be a transmitting component that can transmit radar, sonar, laser or Beacon signals, etc. The embodiment of the present application does not impose any specific restrictions on the transmitting component.

The server is usually located at a remote location, and the mobile terminal and the monitoring terminal can respectively establish network connections with the server to realize information transmission.

The shelf object may refer to an item placed in a shelf, including a plurality of items. Each shelf is composed of multiple layers of racks, and the shelf object is specifically placed in the racks.

The server can distinguish different shelf objects based on the object processing information. Specifically, the object processing information may include an object identifier. The server can obtain the object identifier of the shelf object from the object processing information to distinguish different shelf objects processed by the mobile terminal. The server can store the object position of each shelf object in correspondence with the object identifier. The generated map can also distinguish different shelf objects by the object identifier. The object identifier can refer to the object name of the shelf object, etc.

Optionally, as another embodiment, the mobile terminal processes the shelf objects in the shelf to obtain the object processing information by:

Scan the shelf object in the shelf to obtain object processing information, which is also the scan information obtained by scanning the code. The scan information may include an object identifier, so that the server can identify different shelf objects processed by the mobile terminal based on the object processing information.

One possible implementation of scanning a shelf object on a shelf by a mobile terminal is to scan the object information code on the outer packaging of the shelf object. The object information code can be a one-dimensional code or a two-dimensional code, and is an identifier for the shelf object. The object information code may include object identification, origin, and/or price, and other object-related information. Therefore, the object processing information obtained includes at least the object identification.

As another possible implementation method, a label can be placed on the shelf for each shelf object. In shopping places such as supermarkets and shopping malls, the label refers to the price tag, and each shelf object is a commodity. Each commodity corresponds to a price tag, which is used to display the name, price and/or origin of the commodity and other object-related information. The label can be specifically an electronic label. An electronic label refers to an electronic display device placed on a shelf to replace the traditional paper label, which can display object-related information such as price, information code, trademark, inventory, etc., and the object-related information can be modified. In shopping places, electronic labels are also electronic shelf labels (Electronic Shelf Label System, ESL).

Each label may be provided with a label information code, and the type of the label information code may be a one-dimensional code or a two-dimensional code.

When the label is not bound to the shelf object, the shelf object in the shelf scanned by the mobile terminal can be the object information code of the shelf object in the shelf scanned and the label information code of the label corresponding to the shelf object. The object processing information includes the label information code and the object information code, so that the server can also establish a correspondence between the label information code and the object information code based on the scan information. When the label is an electronic label, the object-related information can also be determined based on the object information code and sent to the electronic label. The electronic label displays the object-related information, thereby realizing the binding of the shelf object and the label; at the same time, according to the corresponding wireless signal when the mobile terminal scans the code, the scanning position of the mobile terminal is located.

Therefore, in actual applications, while using a mobile terminal to bind shelf objects and labels, the object position of the shelf objects can be located, and a map can be generated based on the object position of each shelf object. The operation is simple and convenient, without the need for additional tedious steps, further improving the drawing efficiency.

Of course, as another possible implementation, if the label and shelf object are already bound, the server can store the correspondence between the object information code and the label information code. The shelf object in the shelf scanned by the mobile terminal can be the label information code on the label corresponding to the scanned shelf object, and the scanned information includes the label information code. After receiving the label information code, the server can determine the object information code corresponding to the label information code, thereby knowing which shelf object was scanned.

As another embodiment, the mobile terminal processes the shelf object in the shelf to obtain the object processing information specifically:

Acquire shelf objects in the shelf to obtain object processing information, where the object processing information is an image of the shelf object;

The server is further configured to recognize the image of the shelf object to determine the object identifier of the shelf object, thereby distinguishing different shelf objects.

The server can save images of different shelf objects, so that the shelf object can be identified based on the image captured by the mobile terminal to determine the object identifier of the shelf object.

Of course, the image of the shelf object can be obtained by collecting the identification area of the shelf object by the mobile terminal. Since the outer packaging of the shelf object usually marks the object name, object information code, etc. of the shelf object, the identification area can be, for example, the area where the object information code is located in the outer packaging of the shelf object, the area where the object identification is located, etc., so that the server can obtain the object identification through image recognition technology.

As another embodiment, the mobile terminal processes the shelf object in the shelf to obtain the object processing information specifically:

collecting shelf objects in the shelf to obtain images of the shelf objects;

The image of the shelf object is recognized to obtain object processing information, where the object processing information may be an object identification of the shelf object.

That is, the mobile terminal can perform image recognition to obtain the object label of the shelf object. As another embodiment, when the shelf object and the label are bound, the server saves the corresponding relationship between the object information code and the label information code.

The tag can emit a specific signal. The mobile terminal can receive the specific signal as long as it is close to the tag. The specific signal can carry the tag information code. Therefore, the mobile terminal processes the shelf object in the shelf to obtain the object processing information specifically as follows:

The mobile terminal receives a specific signal transmitted by a tag corresponding to a shelf object in the shelf to obtain object processing information, which is the tag information code.

The server can then look up the corresponding object information code based on the label information code, thereby determining the object identifier of the shelf object.

The specific signal may be an NFC (Near Field Communication) signal.

In this embodiment, the mobile terminal is used to transmit wireless signals and can process shelf objects in the shelf to obtain object processing information; the object processing information is sent to the server; the monitoring terminal can receive the wireless signal and send the wireless signal to the server; the server can locate the processing position of the mobile terminal based on the corresponding wireless signal when the mobile terminal processes the shelf object; the processing position can be used as the object position of the shelf object; based on the object position of the shelf object, a map can be generated. The embodiment of the present application realizes the automatic generation of the map without manual drawing, thereby improving the accuracy of the map.

In practical applications, the mobile terminal may be a handheld device that is easy to carry, so that the staff only needs to operate the mobile terminal to scan the code of the shelf object in the shelf to realize the automatic generation of the map.

In indoor places, shelf objects are arranged on shelves, and shelf aisles are usually set between shelves to facilitate user movement.

Therefore, in some embodiments, the server is further configured to locate the unprocessed position of the mobile terminal based on the wireless signal emitted when the mobile terminal does not process the shelf object and the position of the corresponding monitoring terminal; and use the unprocessed position as the shelf aisle position;

The monitoring terminal corresponding to the mobile terminal when the mobile terminal does not process the shelf object may refer to a monitoring terminal that receives a wireless signal transmitted when the mobile terminal does not process the shelf object.

Therefore, the service end specifically locates the unprocessed position of the mobile terminal based on the wireless signal emitted when the mobile terminal does not process the shelf object and the position of the monitoring end that receives the wireless signal emitted when the mobile terminal does not process the shelf object.

Optionally, the corresponding monitoring terminal may be selected to locate the unprocessed position of the mobile terminal in order of the signal strength of the received wireless signal from strong to weak.

The server generates a map according to the object position of the shelf object by:

A map is generated based on the object position of the shelf object and the shelf aisle position.

In addition, the server can first determine the shelf position based on the object position of each shelf object, so that the shelf can be drawn first according to the shelf position and the shelf channel position, and then the shelf objects in the shelf can be drawn according to the object position of the shelf object to generate a map.

Among them, the positioning algorithm can be implemented in various ways.

The server can use the TOA (Time of Arrival) algorithm or the TDOA (Time Difference of Arrival) algorithm to locate the mobile terminal. If the wireless signal is emitted by the mobile terminal while processing a shelf object, the calculated mobile terminal position is the processed position. If the wireless signal is emitted by the mobile terminal before processing a shelf object, the calculated mobile terminal position is the unprocessed position.

Taking two-dimensional coordinates as an example, assuming that the position coordinates of the mobile terminal are (x, y) and the position coordinates of the monitoring terminal are ( _xi , _yi )

The calculation formula using the TOA algorithm can be:

_ri = ( _ti - _t0 ) c;

r _i ² =(x _i -x) ² +(y _i -y) ² ;

Where c is the speed of light, _ri is the distance between the mobile terminal and the i-th monitoring terminal, and _ti is the arrival time of the wireless signal transmitted by the mobile terminal to the i-th monitoring terminal. _t0 represents the arrival time of the wireless signal to the mobile terminal and is usually 0.

Using the TOA formula above, at least two monitoring terminals are required for two-dimensional coordinates, that is, the position coordinates of the mobile terminal can be calculated.

The calculation formula using the TDOA algorithm can be:

_rij = ( _ti - _tj ) c

_ri ² = _ri ² -r _j ²

=(x _i -x) ² +(y _i -y) ² -(x _j -x) ² -(y _j -y) ²

Where c is the speed of light, _ri is the distance between the mobile terminal and the i-th monitoring terminal, and _rj is the distance between the mobile terminal and the j-th monitoring terminal. _ti is the arrival time of the wireless signal transmitted by the mobile terminal at the i-th monitoring terminal. _tj is the arrival time of the wireless signal transmitted by the mobile terminal at the j-th monitoring terminal. ( _ti - _tj ) is the arrival time difference between the wireless signal transmitted by the mobile terminal at the i-th monitoring terminal and the arrival time difference at the j-th monitoring terminal, where i is not equal to j, and j = 1, 2, 3, etc.

Using the above TDOA formula, for two-dimensional coordinates, at least three monitoring terminals are required to calculate the position coordinates of the mobile terminal.

The use of TDOA can avoid time errors and further improve calculation accuracy. In some embodiments, the wireless signal transmitted by the mobile terminal can be a UWB signal, a radar signal, a sonar signal, a laser signal, etc.

In addition, since the indoor space is large, in order to ensure that the position of the mobile terminal can be accurately located, multiple monitoring terminals can be included. Each time positioning is performed, a corresponding number of monitoring terminals can be selected to locate the position of the mobile terminal in the order of signal strength from strong to weak.

In practical applications, the map is specifically a three-dimensional electronic map, so the position of the mobile terminal obtained by positioning can be a three-dimensional coordinate.

In addition, when using the TOA algorithm to locate the position of a mobile terminal, each monitoring terminal can also calculate the distance between itself and the mobile terminal based on the arrival time, and then upload the distance to the server, which will calculate the position of the mobile terminal based on the distance and distance formula.

Therefore, as another embodiment, the present application provides a map generation system. The system may include a server, a mobile terminal, and a monitoring terminal. The connection relationship between the components can be seen in FIG1 .

The monitoring terminal is arranged at a preset position in an indoor place. Optionally, the monitoring terminal can be specifically arranged on the ceiling of the indoor place.

The monitoring terminal may include multiple monitoring terminals. The mobile terminal may transmit wireless signals, and the monitoring terminal may receive the wireless signals transmitted by the mobile terminal.

Specifically:

The mobile terminal is used to transmit wireless signals; process shelf objects in the shelf to obtain object processing information; and send the object processing information to the server;

The monitoring terminal is used to receive the wireless signal; calculate the distance to the mobile terminal according to the wireless signal; and send the distance to the service terminal;

The server is used to determine the shelf object processed by the mobile terminal based on the object processing information; locate the processing position of the mobile terminal based on the corresponding distance when the mobile terminal processes the shelf object and the position of the monitoring terminal that sends the distance; use the processing position as the object position of the shelf object; and generate a map based on the object position of the shelf object.

In this embodiment, the monitoring end may first calculate the distance to the mobile terminal, and then the service end may locate and obtain the processing position of the mobile terminal based on the distance and the distance formula.

The monitoring terminal may calculate the distance from the mobile terminal by using the arrival time, or other calculation methods such as signal strength, which is not specifically limited in this embodiment.

The object processing information sent by the mobile terminal may also include the processing time, and the distance sent by the monitoring terminal may also include the reception time of the wireless signal. Therefore, the distance corresponding to when the mobile terminal processed the shelf object can optionally be determined based on the processing time and the reception time of the wireless signal. By searching for the distance corresponding to the reception time that is consistent with the processing time or within a preset error range, the distance corresponding to when the mobile terminal processed the shelf object can be determined. By combining the location of the monitoring terminal whose reception time is consistent with the processing time or within a preset error range, the processing location of the mobile terminal can be located.

In this embodiment, the mobile terminal transmits a wireless signal and can process the shelf objects in the shelf to obtain object processing information; the object processing information is sent to the server; the monitoring terminal can receive the wireless signal and calculate the distance from the mobile terminal based on the wireless signal, and send the distance to the server; the server can locate the processing position of the mobile terminal based on the corresponding distance when the mobile terminal processes the shelf object; the processing position can be used as the object position of the shelf object; based on the object position of the shelf object, a map can be generated. The embodiment of the present application realizes the automatic generation of the map without manual drawing, thereby improving the accuracy of the map.

In addition, the server can also locate the unprocessed position of the mobile terminal based on the corresponding wireless signal when the mobile terminal does not process the shelf object; and use the unprocessed position as the shelf aisle position;

Therefore, the server generates a map specifically based on the object position of the shelf object and the shelf aisle position.

In addition, as another embodiment, the present application also provides a map generation system, which includes a service end, a mobile terminal and a monitoring end; the monitoring end is arranged at a preset position in an indoor place, specifically in the indoor ceiling, and its position is known.

In this embodiment, the monitoring end corresponding to the mobile terminal processing the shelf object may refer to the monitoring end that transmits the wireless signal received when the mobile terminal processes the shelf object.

When the mobile terminal processes the shelf object, it can receive wireless signals transmitted by multiple monitoring terminals, and can select the corresponding wireless signal and the position of the monitoring terminal that transmits the corresponding wireless signal in order of signal strength from strong to weak to locate the processing position of the mobile terminal.

In this embodiment, a monitoring terminal transmits a wireless signal, and a mobile terminal receives the signal and transmits it to a server. If object processing information is obtained, the server transmits it to the server. Based on this object processing information, the server can distinguish between different shelf objects. Thus, based on the wireless signal received when the mobile terminal processes the shelf object, the server can locate the processing position of the mobile terminal and use it as the object location of the shelf object. Based on the object location of the shelf object, a map can be generated. This enables automatic map generation, eliminating the need for manual drawing and improving map accuracy.

In addition, the server can also locate the unprocessed position of the mobile terminal based on the corresponding wireless signal when the mobile terminal does not process the shelf object; and use the unprocessed position as the shelf aisle position; so that the server specifically generates a map based on the object position of the shelf object and the shelf aisle position.

The mobile terminal is used to process the shelf object in the shelf to obtain object processing information; locate the processing position of the mobile terminal according to the wireless signal received when processing the shelf object and the position of the corresponding monitoring terminal; use the processing position as the object position of the shelf object; and send the object position of the shelf object and the object processing information to the server;

The server is configured to determine the shelf object processed by the mobile terminal according to the object processing information; and generate a map according to the object position of the shelf object.

The monitoring end corresponding to the mobile terminal when processing the shelf object may refer to the monitoring end that transmits the wireless signal received when the mobile terminal processes the shelf object.

Among them, when the mobile terminal processes the shelf object, it can receive wireless signals transmitted by multiple monitoring terminals, and can select the corresponding wireless signal and the position of the monitoring terminal that transmits the corresponding wireless signal in order of signal strength from strong to weak to locate the processing position of the mobile terminal.

In this embodiment, a monitoring terminal transmits a wireless signal, and a mobile terminal receives the wireless signal transmitted by the monitoring terminal. The mobile terminal locates the processing position of the mobile terminal based on the wireless signal received when processing the shelf object, and uses the processing position of the shelf object as the object position of the shelf object, which is then sent to the server. The server can distinguish different shelf objects based on the object processing information of the shelf object, and thus generate a map based on the object position of each shelf object. This achieves automatic map generation, eliminating the need for manual drawing and improving map accuracy.

In addition, the mobile terminal can also locate the unprocessed position of the mobile terminal based on the wireless signal received when the shelf object is not processed and the position of the corresponding monitoring terminal; use the unprocessed position as the shelf aisle position, and send the shelf aisle position to the server; so that the server can generate a map based on the object position of the shelf object and the shelf aisle position.

In some of the above embodiments, the server may generate a map based on the object position of the shelf object and the shelf aisle position by:

Determine a map boundary; and generate a map within the map boundary based on the object position of the shelf object and the shelf aisle position.

The map boundaries can be determined based on the building dimensions marked on the interior architectural drawings.

In practical applications, indoor places usually include some indoor passages, such as stairs, elevators, fire escapes, etc. These indoor passages can be obtained from architectural drawings. The dimensions and boundaries of the place can also be determined from the architectural drawings, thereby determining the map boundaries.

Therefore, the server can generate a map specifically within the map boundary according to the object position of the shelf object, the shelf aisle position and the indoor aisle position.

In practical applications, because there are many objects on shelves in indoor spaces, they can be categorized and arranged according to their object categories. Different indoor spaces have different classification requirements, and therefore different object categories. For example, in a supermarket, object categories may include fresh produce, grains, oils, and condiments, alcoholic beverages and instant drinks, daily necessities and household items, stationery and home appliances, and so on. Alternatively, they may include shampoo, towels, televisions, washing machines, and so on.

Therefore, in some embodiments, the server may generate a map based on the object position of the shelf object and the shelf aisle position, including:

Generate a category distribution submap based on the object category to which the shelf object belongs and the object position of the shelf object; specifically, determine the position of the object category based on the object position of the shelf object in the same object category, and then generate a category distribution submap based on the position of each object type;

For each object category in the category distribution submap, draw the shelf according to the object position of the shelf object and draw the shelf aisle according to the shelf aisle position, to generate a shelf distribution submap corresponding to each object category;

For each shelf in the shelf distribution submap, an object distribution submap corresponding to each shelf is generated according to the object position of the shelf object; that is, the shelf object in the shelf is drawn in each shelf to generate an object distribution submap;

An association relationship among the category sub-map, the shelf distribution sub-map, and the object distribution sub-map is established to generate a map.

The object distribution submap may also include object-related information for each shelf object, such as object identification, price, and image. Alternatively, an object distribution submap corresponding to each shelf object may be generated based on the object location and object-related information of each shelf object. The category distribution submap may also generate the category name of each object category. The shelf distribution submap may also generate the category name of the object category to which each shelf object belongs.

In some embodiments, since object categories can be further refined, each object category may not only correspond to one shelf, but each shelf may also correspond to multiple object categories.

Assume that the object category can be further divided into multiple object types. For example, daily necessities can be further divided into shampoo, towels, etc.

Therefore, for each object category in the category distribution submap, the shelf is drawn according to the object position of the shelf object and the shelf aisle is drawn according to the shelf aisle position to generate the shelf distribution submap corresponding to each object category.

For each object type in each object category in the category distribution submap, a shelf is drawn according to the object position of the shelf object and a shelf aisle is drawn according to the shelf aisle position to generate a shelf distribution submap.

The object position used to draw the shelf distribution submap corresponding to any object category is the object position of the shelf object under the object category, and the shelf aisle position is the shelf aisle position corresponding to the object category.

Since the map boundary may be determined first when generating the map, a category distribution sub-map may be generated within the map boundary according to the position of each object and the object category to which each object belongs.

When drawing shelves and shelf aisles, you can also draw indoor passages, such as stairs, elevators, and fire escapes. Indoor passages can be determined from architectural drawings.

Therefore, for each object category in the category distribution submap, the shelf is drawn according to the object position of the shelf object, the shelf aisle is drawn according to the shelf aisle position, and the indoor aisle is drawn according to the indoor aisle position, so as to generate a shelf distribution submap corresponding to each object category;

Among them, when drawing the shelf, it can be combined with the shelf size, and the shelf size can be set in advance.

In addition, since indoor places such as supermarkets, shopping malls, or warehouses usually include multiple rooms, different rooms can be on the same floor or on different floors; the object categories of the shelf objects placed in each room may be different. For example, the room on the first floor may be filled with daily necessities, while the room on the second floor may be filled with household items.

The monitoring end may be arranged in each room, so that the service end may obtain the object position of the shelf object and the shelf aisle position, etc. in each room.

Therefore, in some embodiments, the server generates a category distribution submap based on the object position of the shelf object and the object category to which the shelf object belongs, which may be:

A category distribution submap of each room is generated according to the object positions of the shelf objects in each room and the object categories of the shelf objects.

Therefore, we can create sub-maps for each room category and generate corresponding shelf distribution sub-maps and object distribution sub-maps.

In which, corresponding switching prompt information can also be drawn in the category distribution sub-map, shelf distribution sub-map or object distribution sub-map of each room. The switching prompt information is used to prompt the user to switch to the category distribution sub-map, shelf distribution sub-map or object distribution sub-map of the corresponding room.

For example, when outputting the category distribution submap of any room, the user can request to switch to outputting the item category distribution submap of another room according to the corresponding switching prompt information; when outputting the shelf distribution submap of any room, the user can request to switch to outputting the shelf distribution submap of another room according to the corresponding switching prompt information; when outputting the object distribution submap of any room, the user can request to switch to outputting the item distribution submap of another room according to the corresponding switching prompt information.

The following example uses a supermarket as an indoor location, as shown in Figures 2a to 2d. Figures 2a and 2b are schematic diagrams of category distribution submaps, respectively. Figure 2a shows the category distribution submap corresponding to the first-floor room, and Figure 2b shows the category distribution submap corresponding to the second-floor room. The category distribution submap includes the location areas of different object categories and may also include switching prompt information 200. The switching prompt information 200 may be a virtual control. By operating the virtual control, the category distribution submap of the room corresponding to the switching prompt information 200 may be triggered.

FIG2c is a schematic diagram of a shelf distribution submap. The object category of each shelf can also be marked in the shelf distribution submap. In FIG2c , it is marked that the object category of shelf 201 is alcoholic beverages, and the object category of shelf 202 is condiments.

FIG2 d is a schematic diagram of an object distribution sub-map. FIG2 d is the object distribution sub-map corresponding to shelf 201 , which may include the distribution location of each shelf object in the shelf and object-related information.

It should be noted that after each sub-map is output, it can be zoomed in and out so that maps of different precisions can be viewed.

The map generated using the technical solution of the embodiment of the present application can have multiple applications. Several possible implementation methods will be listed in the following embodiment. Of course, the embodiment of the present application is not limited to this.

In some embodiments, the server can also send the map to the user terminal, so that after the user terminal receives the map, it outputs the category sub-map; when receiving a shelf output request for any object category in the category sub-map, it outputs the corresponding shelf distribution sub-map; when receiving an object output request for any shelf in the shelf distribution sub-map, it outputs the object distribution sub-map corresponding to the request.

Each output request may be triggered by a user. The user may trigger an output request by clicking or performing other specific operations on any item category or any item shelf in the sub-map.

In the object distribution sub-map, when a content output request for any shelf object in the object distribution sub-map is received, object-related information of any shelf object can also be output, including detailed information such as object identification, price, origin, etc., so that users can understand the shelf objects without entering indoor places.

In some embodiments, the server is also used to send the map to a user terminal so that the user terminal can output the map; receive a navigation request from the user terminal, the navigation request including an object identifier of at least one target shelf object; query the object position of the at least one target shelf object based on the object identifier of the at least one target shelf object; generate navigation prompt information based on the object position of the at least one target shelf object and the terminal position of the user terminal; and trigger the user terminal to output the navigation prompt information in the map.

The navigation prompt information may include navigation path information. The server may plan a navigation path according to the object position of each shelf object to prompt the user to find the target shelf object according to the navigation path.

In some embodiments, the server is also used to send the map to the user terminal so that the user terminal can output the map; and according to the terminal location of the user terminal, send relevant recommendation information of the shelf object matching the terminal location to the user terminal so that the user terminal can output the relevant recommendation information.

According to the change of the terminal location of the user terminal, different relevant recommendation information can be pushed.

When a user carries a user terminal and moves around in an indoor place, he or she can find the shelf object closest to the terminal location based on the terminal location, that is, he or she can push relevant recommendation information of the shelf object to the user terminal. The relevant recommendation information can be, for example, promotional information of the shelf object, discount vouchers for the shelf object, or object-related information of other shelf objects similar to the shelf object, etc.

In some embodiments, the server is also used to send the map to a user terminal so that the user terminal can output the map; receive an object search request from the user terminal, the object search request including an object identifier of the object to be found; determine the object location of the object to be found based on the object identifier of the object to be found; and trigger the user terminal to output search prompt information at the object location of the object to be found in the map.

In the map output by the user terminal, the user can also search for shelf objects to trigger an object search request, so that the server can trigger the user terminal to output search prompt information at the object location of the object to be found in the map to identify the object to be found and facilitate user search.

The user may trigger a content output request according to the search prompt information, so that the server may send object-related information of the shelf object to the user terminal for output by the user terminal.

Of course, the user can also trigger a navigation request based on the search prompt information, so that the server can generate navigation prompt information based on the current terminal location of the user terminal and the object location of the object to be found, and trigger the user terminal to output it. According to the navigation prompt information, the user can quickly find the shelf object.

As can be seen from the above description, the map generated using the technical solution of the embodiment of the present application can facilitate the search for shelf objects. In practical applications, when the map is a shopping place, such as an indoor map of a supermarket, the map can help customers find the location of the products they want to buy, push relevant information such as coupons to customers, and help employees or suppliers find the location of products that need to be replenished or exchanged. Of course, the application of the map described in the embodiment of the present application is not limited to this.

In an embodiment of the present application, in order to facilitate information transmission and control, the service end may include at least a proximal server and a remote server. The proximal server, the monitoring end, and the mobile terminal may be deployed in the same local area network, while the remote server is deployed at the network end and establishes a connection with the proximal server through the Internet.

Therefore, the monitoring end can specifically send the wireless signal or the distance to the mobile terminal calculated based on the wireless signal to the remote server through the near-end server; the remote server then locates the processing position of the mobile terminal as the object position of the shelf object, and generates a map based on the object position of each shelf object.
