Detailed ways

In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

In the related technology, taking the parking navigation in the park as an example, when the user needs to navigate to enter the indoor parking lot of the park to park, he can only navigate to the building where the indoor parking lot is located, but cannot show the user the specific location of the indoor parking lot in the indoor building. This requires the user to open the indoor positioning software or find the location of the parking lot indoors by himself, which reduces the user experience.

In view of this, the present disclosure provides a navigation method and system, which, when receiving a navigation request for a target area, obtains corresponding map data according to the type of current location information, and renders a first navigation page for navigation. When the type of location information changes, the corresponding map data is obtained according to the type of the changed location information, and then a second navigation page is rendered, so that when a user enters an outdoor area from an indoor area, or enters an indoor area from an outdoor area, the first navigation page can be directly switched to the second navigation page, thereby achieving seamless switching of navigation in different scenarios and improving user experience.

Referring to FIG. 1 , FIG. 1 shows a flowchart of steps of a navigation method provided by an embodiment of the present disclosure. As shown in FIG. 1 , the navigation method can be applied to a terminal, specifically a smart mobile terminal, such as a mobile phone, a tablet, etc. The navigation method can specifically include:

S101, in response to a navigation request of a target area, obtaining map data based on real-time acquired location information and a type corresponding to the location information, and rendering a first navigation page based on the map data and the location information.

In this embodiment, the target area is an area where both outdoor scenes and indoor scenes exist, such as a park, a scenic spot, a shopping mall, etc., then when navigating the target area, the map data obtained may include global map data describing the global target area, and local map data of the local area of the target area. Among them, the global map data may be map data overlooking the target area outdoors, that is, including road information, building information, etc. of the target area, and the local map data may be a floor map of the indoor scene in the target area. Among them, the map data can be acquired in advance when entering the target area, then when receiving a navigation request, the map data to be loaded can be directly determined according to the type of location information; or it can be acquired when receiving a navigation request, and then the map data to be loaded can be determined according to the location information.

Among them, the type of location information may include longitude and latitude type and radio wave signal type. It is understandable that in outdoor scenarios, if the terminal can receive GPS signals, it can directly obtain GPS coordinates for positioning. At this time, the location information received by the terminal is longitude and latitude type location information; in indoor scenarios, if it is difficult for the terminal to obtain GPS signals, radio waves can be used for indoor positioning. At this time, the location information received by the terminal is of radio wave signal type. During the navigation process, the terminal can obtain longitude and latitude information or location information based on radio wave signals to determine whether the user is currently in an outdoor scene or an indoor scene. If the user is in an outdoor scene, the global map data of the target area can be loaded; if the user is in an indoor scene, the local map data of the target area can be loaded.

For example, taking the case where the user is located in a park, when the location information obtained is the latitude and longitude information sent by the GPS, it indicates that the user is located in the outdoor area of the park, and the global map of the park is loaded to realize navigation for the user. If the location information obtained is the location information of the radio wave signal type, it indicates that the user is in the indoor area of the park, and the indoor local map of the park is loaded to navigate the user.

In this embodiment, the location information of the radio wave signal type can be sent by a Bluetooth beacon. By setting multiple Bluetooth beacons indoors, the terminal communicates with the Bluetooth beacons through Bluetooth signals, and the terminal can receive the location information of the radio wave signal type. For example, a Bluetooth beacon can be set every 5 meters in the indoor area so that it can cover all indoor areas.

It is understandable that parks, scenic spots and other areas may include one or more indoor scenes, such as different floors of the same building, or different buildings; then when multiple indoor scenes are included, each indoor scene can correspond to a local map data separately. Then, when the acquired location information is of the radio wave signal type, the specific indoor scene where the user is currently located can be determined based on the location information, and then the corresponding local map data can be obtained for navigation.

In this embodiment, the first navigation page can be map data rendered in 3D mode or 2D mode. A switching control can also be added to the navigation page so that the user can choose to display 3D map data or 2D map data.

S102: When it is detected that the type of the location information has changed, the first navigation page is switched to the second navigation page.

The second navigation page is rendered by the location information obtained at the current moment and the map data corresponding to the changed type.

Specifically, when the type of received location information changes, it indicates that the user has entered a different scene. For example, when the location information changes from the latitude and longitude type to the radio wave type, it indicates that the user has entered an indoor scene from an outdoor scene, and when the location information changes from the radio wave type to the latitude and longitude type, it indicates that the user has entered an outdoor scene from an indoor scene. Since the global map data cannot display indoor map data and the local map data cannot display outdoor map data, the navigation page can be switched when the user enters the outdoor from the indoor or the outdoor from the outdoor to the indoor, so as to directly realize navigation from the outdoor to the indoor or from the indoor to the outdoor.

When the user enters an outdoor scene from an indoor scene, or enters an indoor scene from an outdoor scene, and the current first navigation page does not include map data of the scene to be entered, the required map data can be determined according to the type of the changed location information, and the second navigation interface can be rendered according to the map data and location information, and then the first navigation page can be switched to the second navigation page to display the map data of the scene to be entered on the terminal and navigate for the user.

Wherein, referring to FIG. 2, FIG. 2 shows a schematic diagram of the change of the navigation page when the user moves from one scene to another scene in the embodiment of the present disclosure. As shown in FIG. 2, when the user is in a certain scene, the user obtains the first type of location information, which can be the location information of the latitude and longitude type, or the location information of the radio wave signal type. At this time, the terminal displays the first navigation page. Afterwards, when the user moves from the current scene to another scene, the first type of location information obtained is changed to the second type of location information. At this time, the terminal displays the second navigation page in the same window to realize the switching between the first navigation page and the second navigation page.

For example, when the current first navigation page displays a local map and the user's current location, the user is in an indoor scene, and when the user enters an outdoor scene from the indoor scene, the terminal receives location information of the longitude and latitude type. At this time, the second navigation page can be rendered based on the received longitude and latitude type location information and the global map data, that is, a navigation page that displays the global map, and then the first navigation page is switched to the second navigation page; and when the current first navigation page displays the global map and the user's current location, the user is in an outdoor scene, and when the user enters the indoor scene from the outdoor scene, the terminal receives location information of the radio wave signal type. At this time, the second navigation page can be rendered based on the received location information of the radio wave signal type and the local map data, that is, a navigation page that displays the local map, and then the first navigation page is switched to the second navigation page.

In this embodiment, the second navigation page can be map data rendered in 3D mode or 2D mode. A switching control can also be added to the second navigation page to display 3D map data or 2D map data according to user selection.

By adopting the navigation method provided in the embodiment of the present disclosure, when navigating to a target area, corresponding map data is obtained according to the type of location information obtained in real time to generate a first navigation page for navigation for the user, and when the type of location information obtained changes, the first navigation page is switched to a second navigation page generated by map data corresponding to the type of the current location information. Thus, in different scenarios, the maps displayed on the navigation page are different, thereby achieving distinction between the scenes of the specific location of the user, and when the scene where the user is located switches, there is no need for the user to manually switch the navigation page, and seamless switching of navigation in different scenarios can be achieved, thereby improving the user experience.

Among them, the first navigation page can be obtained by rendering map data in two-dimensional mode or three-dimensional mode; similarly, the second navigation page can be obtained by rendering map data in two-dimensional mode or three-dimensional mode.

In one embodiment, specifically, when the type of the location information changes from the latitude and longitude type to the radio wave signal type, the first navigation page renders the global map data in a three-dimensional mode, and the second navigation page renders the local map data and the location information obtained at the current moment in a two-dimensional mode;

When the type of location information changes from a radio wave signal type to a latitude and longitude type, the first navigation page renders local map data in a two-dimensional mode, and the second navigation page renders global map data and location information acquired at the current moment in a three-dimensional mode.

Specifically, in order to distinguish the first navigation page from the second navigation page, the map data rendering modes of the first navigation page and the second navigation page may be different, so that the page displays of the first navigation page and the second navigation page are different, so that it is convenient for users to distinguish between the global map and the local map. Considering that the global map data includes not only outdoor map data but also map data of multiple floors indoors, the global map data may be rendered in a three-dimensional mode, while the local map data may be rendered in a two-dimensional mode. In this way, when the global map is displayed on the navigation page, it is convenient for users to intuitively view the spatial layout of a multi-story building, and it is convenient to determine the local map data corresponding to the user's location based on the global map data when receiving the location information of the radio wave signal type.

In one embodiment, since different types of location information obtain different map data, the required map data can be determined based on the type of location information obtained, and then the corresponding map data can be obtained; specifically, when the type is a longitude and latitude type, global map data is obtained, and the global map data and location information are rendered in the target window to obtain the first navigation page; and when the type is a radio wave signal type, local map data corresponding to the location information is obtained, and the local map data and location information are rendered in the target window to obtain the first navigation page.

Specifically, by rendering global map data and local map data in the same target window, it is possible to display the first navigation page or the second navigation page in the same window. In this way, when the user moves from an indoor area to an outdoor area, or from an outdoor area to an indoor area, the navigation can be viewed through the same window, avoiding the need to switch to different windows for display when navigating in different areas, which reduces the user experience.

In this embodiment, the target window can be an application window or a web page window, and the first navigation page can be displayed on the application interface or on the web page. The rendering of the navigation page can be realized by the webview technology, and the map url (Uniform Resource Locator) address is used as the source (src) attribute value of the webview component to realize the display of the map page in the application and navigation. The location information obtained at the current moment can be hashed. When the location information changes, the webview listens to the hashchange event to synchronize the navigation information to the webview, so as to realize real-time navigation.

It should be noted that the target area may include multiple different indoor areas, and each indoor area is independent. When the user enters the indoor area, the identification of the indoor area can be determined first, and then the corresponding map data can be obtained according to the identification of the indoor area. Specifically, the map data may carry multiple preset identifications and the location corresponding to each preset identification, and different preset identifications identify different radio devices; in this case, the process of obtaining local map data may specifically be:

First, the strength value and target identifier of the radio wave signal are parsed from the location information; wherein the strength value represents the distance between the terminal and the radio equipment set in the target area; then, the target preset identifier corresponding to the target identifier and the target position corresponding to the target preset identifier are determined from multiple preset identifiers; then, the local map data where the target position is located is obtained.

In this embodiment, when the target area is an indoor area, the radio wave signal strength of multiple radio devices and the target identifier carried by each radio device can be determined from the received location information. The target identifier can carry the location information of the radio device, such as the indoor location coordinates and floor of the radio device. Then, the user's current location can be determined based on the strength values of the radio wave signals of multiple radio devices, the location coordinates and floor of each radio device, thereby achieving accurate positioning of the indoor area.

The target identifier may be an area identifier of multiple sub-areas in the target area, each sub-area representing a building, and the building where the user is located can be determined according to the target identifier to achieve loading of local map data. It is understandable that each building may include multiple floors, and the target identifier may also include floor information to achieve loading of local map data of the floor where the user is located.

For example, when determining the target identifier corresponding to the location information, the target identifier is matched with multiple preset identifiers on the global map to determine the target preset identifier corresponding to the target identifier, and then the target position of the target preset identifier on the global map can be determined, thereby obtaining the local map data corresponding to the target position.

For example, in the process of indoor navigation through Bluetooth beacons, multiple Bluetooth beacons can be pre-configured indoors, and the location of each Bluetooth beacon can be marked in the global map. Then, when the location information received by the terminal is of the radio wave type, it can actually include Bluetooth signals sent by multiple Bluetooth beacons. Then, based on the identification carried by the Bluetooth beacon, its specific building and specific floor in the global map can be determined, and the map data of the corresponding floor can be obtained.

For example, if a Bluetooth beacon is deployed at a certain location on the underground 1st floor, a Bluetooth beacon can be synchronously arranged at the same location on the global map. The Bluetooth beacon will have a uuid (unique id), which is also used in series when the map is deployed. Therefore, when receiving the Bluetooth signal of the surrounding Bluetooth beacons, the id of the surrounding Bluetooth beacons and the signal strength of each Bluetooth beacon can be obtained according to the location information of the Bluetooth signal. Then, based on the uuid and the Bluetooth beacon signal strength, the location of the Bluetooth beacon on the map can be determined, and the user's current location can be returned. The location information of the Bluetooth beacon after deployment can be stored on a remote server.

Among them, taking the location information returned by the Bluetooth beacon on the second underground floor received by the terminal as an example, when the Bluetooth beacon signal is received, the target preset identifier in the global map that matches the target identifier can be determined based on the target identifier corresponding to the received location information, and the user can be determined to be located on the second underground floor based on the target preset identifier.

In one embodiment, in order to facilitate the switching of navigation pages, the second navigation page can be directly rendered according to the local map and location information. When a navigation request of the target area is received, all local map data in the target area can be pre-downloaded. The process can be specifically:

First, when the navigation request is triggered, the local map data of each floor in each building in the target area is downloaded and cached; then, when the type of location information is latitude and longitude type, the local map data layer of each floor included in each building is obtained from the cache; thereafter, multiple local map data are stacked according to the floors they belong to, so as to obtain a three-dimensional map page; finally, the location information is marked in the three-dimensional map page, so as to obtain the first navigation page in the three-dimensional mode.

In this embodiment, when a navigation request is received, it is determined whether to download local map data in the target area based on the starting point and end point of the navigation. For example, if one of the starting point and end point of the navigation is located outdoors and the other is located indoors, it means that local map data is needed during the navigation process. At this time, the local map data of each floor in each building in the target area can be downloaded and cached; if the starting point and end point of the navigation are both located indoors, or both are located outdoors, the corresponding global map data or the local map data of the corresponding floor in the corresponding building can be obtained; it is also possible that as long as a navigation request is received, the local map data of each floor in each building in the target area is downloaded and cached, and then the required local map data is determined based on the real-time location information.

By adopting the technical solution of this embodiment, when the map data is cached locally, it can realize offline navigation, that is, according to the received GPS location information and radio wave type location information, the map data stored in the terminal can be used to render a navigation page, thereby realizing offline navigation of the terminal.

Among them, by obtaining local map data of each floor of each building in the target area, the local map data corresponding to the multiple floors included in each building can be determined, and then the multiple local map data can be stacked in order of floors to obtain a three-dimensional map that can intuitively display the spatial layout of multiple floors in the building, so as to facilitate marking the location of each radio device in the three-dimensional map. In this way, when the location information of the radio wave signal type of the radio device is received, the building and floor where the user is currently located can be determined according to the location information, and then the corresponding local map data can be obtained according to the location information of the radio wave signal type.

For any of the above embodiments, the method for obtaining longitude and latitude type location information may specifically be: calling the locator configured by the terminal, and obtaining the first longitude and latitude type location information from a third-party server through the locator; the method for obtaining radio wave signal type location information may specifically be: calling the wireless communication module configured by the terminal, and scanning the radio equipment in the target area through the wireless communication module to obtain the second location information of the radio wave signal type.

In this embodiment, the terminal itself may be configured with a locator, and the application in the terminal may call the locator to obtain location information, or the navigation page may be embedded in the application, and the longitude and latitude type location information may be obtained through the third-party server of the application; at the same time, the terminal is configured with a wireless communication module, which can communicate with a radio device, and the second location information of the radio wave signal type sent by the radio device may be received in the wireless communication module of the terminal.

For example, the navigation application of the target area can be embedded in another application as a small program, and the second location information of the radio wave signal type can be obtained through the navigation application itself, and the first location information of the longitude and latitude type can be obtained through another application, thereby enabling the navigation application to receive different types of location information.

Among them, considering that the propagation range of radio wave signals is limited and can only be received in indoor areas, and GPS signals are difficult to accurately determine whether the user is located in indoor areas or outdoor areas, it is possible to determine whether the user is located in indoor areas or outdoor areas based on whether radio wave signals are received.

Specifically, if a navigation request for a target area is received, the first location information can be obtained by calling the locator, and the second location information can be obtained by detecting the wireless communication module. If the second location information is detected, it means that the user is indoors, and if the second location information is not detected, it means that the user is outdoors, and then the corresponding map data is obtained according to whether the user is in an indoor or outdoor area. The process can be specifically as follows:

First, when the navigation request is triggered, the locator is called and the wireless communication module is activated at the same time; then, it is detected whether the wireless communication module obtains the second position information; if the second position information is obtained, the local map data corresponding to the second position information is obtained; if the second position information is not obtained, the global map data is obtained.

In this embodiment, considering that it is difficult to receive radio wave signals of radio equipment outdoors, it is possible to directly detect whether the wireless communication module has acquired the second location information, directly determine the user's location, and then determine the map data that needs to be acquired.

The navigation method provided in the embodiment of the present disclosure is adopted. When a navigation request is received, the locator of the terminal is called and the wireless communication module of the terminal is activated; whether the wireless communication module obtains the second location information is detected to determine the corresponding map data that needs to be obtained, and a first navigation page is generated according to the obtained map data and location information to navigate for the user; then, when the type of location information obtained in real time changes, map data corresponding to the type of current location information is obtained, and a second navigation page is obtained according to the map data and the current location information, so as to continue navigation for the user using the second navigation page, so that when the navigation scene is switched, the user does not need to manually switch the navigation software to achieve navigation in different scenes, thereby improving the convenience and consistency of the navigation service.

The following is an explanation of the navigation method provided by the embodiment of the present disclosure with reference to specific examples:

Example 1: A user navigates from an indoor area of a park to an outdoor area. Referring to FIG. 3 , FIG. 3 shows a schematic flow chart of navigating from an indoor area to an outdoor area using the navigation method provided by an embodiment of the present disclosure. As shown in FIG. 3 , first, upon receiving a navigation request for a target area, the locator is called and the wireless communication module is activated to obtain location information. Next, it is detected whether the wireless communication module receives location information of the radio wave signal type.

If the wireless communication module receives the location information of the radio wave signal type, it means that the user is indoors. At this time, the user's indoor location can be determined based on the strength values of multiple radio wave signals in the location information and the location of each radio device. At the same time, by matching the target identifier carried in the location information with the preset identifier in the map data, the matching target preset identifier is determined, and then the location corresponding to the target preset identifier is determined, thereby obtaining the local map data of the user's location.

Afterwards, a first navigation page is rendered based on the acquired location information and local map data to provide navigation for the user in the indoor area.

When the user enters the outdoor area from the indoor area, the received location information changes from the location information of the radio wave signal to the location information of the longitude and latitude type. Then, the global map data of the park is obtained based on the longitude and latitude type location information, and the second navigation page is rendered based on the currently received location information and the global map data. Then, the terminal display page switches from the first navigation page to the second navigation page, thereby providing navigation for the user in the outdoor area through the second navigation page.

Example 2: A user navigates from an outdoor area of a park to an indoor area. Continuing with FIG3 , first, upon receiving a navigation request to a target area, the locator is called and the wireless communication module is activated to obtain location information. Next, it is detected whether the wireless communication module receives location information of the radio wave signal type.

If the wireless communication module does not receive location information of the radio wave signal type, it means that the user is located in an outdoor area. At this time, the global map data of the park is obtained, and the first navigation page is rendered based on the global map data and the received longitude and latitude type location information to provide navigation services to users in the outdoor area through the first navigation page.

When a user enters an indoor area from an outdoor area, the received location information changes from a longitude and latitude type location to a radio wave signal type location information. The intensity value in the location information can be used to determine the user's specific location in the indoor area; and, based on the target identifier carried in the location information, the local map data corresponding to the user's location can be determined.

Afterwards, a second navigation page is rendered based on the currently acquired location information and local map data, and the first navigation page is switched to the second navigation page to continue providing navigation services to the user in the indoor area.

Based on the same inventive concept, an embodiment of the present disclosure further provides a navigation system. Referring to FIG. 4 , FIG. 4 shows a schematic diagram of the structure of the navigation system provided by an embodiment of the present disclosure. As shown in FIG. 4 , the navigation system is applied to a terminal and may specifically include:

A first application and a web renderer embedded in the first application;

The first application is used to respond to a navigation request of a target area, call a locator and a wireless communication module of the terminal, obtain location information in real time, obtain map data based on the location information obtained in real time and a type corresponding to the location information, and send the map data and the location information to a web renderer;

A web renderer, for rendering the map data and the location information into a first navigation page;

The first application is further configured to send new map data corresponding to the changed type and the location information obtained at the current moment to the web renderer when a change in the type of the location information is detected;

The web renderer is further used to switch the first navigation page to a second navigation page rendered by new map data;

The types include latitude and longitude types and radio wave signal types, different types correspond to different map data of the target area, and the map data include global map data describing the global target area and local map data of a local area of the target area.

The web renderer may be a webview component, which uses the input scr attribute as the URL address of the web page to load and display the web page in the first application. The webview component may be embedded in the first application to display the map in the first application and realize the navigation process of the target area. Afterwards, when the type of location information changes, the webview registers a hashchange event to switch from the first navigation page to the second navigation page, thereby realizing navigation in different scenarios.

Referring to Figure 5, Figure 5 shows a data flow diagram during the navigation process of an embodiment of the present disclosure. As shown in Figure 5, during the navigation process, the first application receives location information of the latitude and longitude type, or location information of the radio wave signal type. At this time, it splices the map URL with the location information and sends it to the web renderer. After that, the web renderer obtains the sent information from the address bar and registers the hashchange event to update the navigation page.

In an optional embodiment, the navigation system further includes a second application, and the first application is embedded in the second application;

The second application is used to activate the first application when detecting that the navigation request is triggered so that the first application responds to the navigation request.

In this embodiment, the second application may be an application that can obtain the location information of the terminal. By embedding the first application in the second application, the first application can obtain the latitude and longitude information of GPS positioning. The second application may include a control for activating the first application. When the user triggers the control, the second application activates the first application for navigation. Alternatively, the second application may be able to parse the relevant image and activate the first application according to the image parsing result.

In an optional embodiment, the second application is specifically used to call the image acquisition device of the terminal in response to the received scanning request, and obtain the identification code image acquired by the image acquisition device;

And, the identification code image is parsed, and when the parsing result indicates navigation to the target area, the first application is activated.

The second application may include a scanning function, and upon receiving a scanning request, it may call the image acquisition device of the terminal to acquire an identification code image, and then if the identification code image represents navigation to the target area, the first application is activated for navigation.

The navigation method provided by the present disclosure is described below in combination with specific scenarios and navigation systems:

Taking the user's navigation in the park as an example, the first application is embedded in the second application in the form of a small program, and the web renderer, i.e., the webview component, is embedded in the small program. When the user has a navigation need, the scanning function of the second application can be used to scan the identification code image to activate the first application.

After the first application is activated, the global map data of the park and the local map data of each local area are loaded according to the navigation needs of the user.

Afterwards, the first application calls the locator of the terminal and activates the radio communication module. At this time, it is detected whether the wireless communication module obtains the location information of the radio wave type.

If the radio wave type location information is obtained, it means that the user is indoors. At this time, the user's location can be determined according to the radio wave device identifier carried in the location information, and then the local map data corresponding to the user's location can be obtained. Then, the local map data and the currently obtained location information can be used to render the first navigation page.

Afterwards, if the user enters the outdoor area from the indoor area, the location information received by the first application changes from the radio wave type to the longitude and latitude type, and the global map data of the park can be obtained based on the longitude and latitude type location information. Afterwards, the second navigation page can be rendered using the global map data and the current location information, and then the first navigation page can be switched to the second navigation page to continue navigating for the user.

If the radio wave type location information is not obtained, it means that the user is outdoors. At this time, the global map data of the park can be obtained based on the obtained longitude and latitude type location information, and then the global map data and the currently obtained location information are used to render the first navigation page.

Afterwards, if the user enters the indoor area from the outdoor area, the location information received by the first application changes from the latitude and longitude type to the radio wave type. The user's local location can be determined based on the radio wave type location information, and then the corresponding local map data can be obtained. Afterwards, the local map data and the current location information can be used to render a second navigation page, and then the first navigation page can be switched to the second navigation page to continue navigating for the user.

The rendering process of the navigation page can be implemented by a web renderer, and the web renderer can include a webview component. Then, the URL address of the map webpage can be configured as the src attribute of the webview component to display the map webpage in the first application. Afterwards, when the user's location information changes, the hash of the URL address can be used to display the user's current location in real time on the map webpage.
