In addition, the multi-space scene may be located within the coverage of the Internet, or may be located outside the coverage of the Internet to work based on a local area network. The multi-space scenarios within the coverage of the Internet include, for example, a teaching building with multiple classrooms, a hospital with multiple wards, or a shopping mall with multiple counters, etc. The multi-space scenarios outside the coverage of the Internet include, for example: Multi-cabin ships far from shorelines, multi-room buildings on isolated islands or remote areas, or multi-studio flying equipment at high altitudes, etc. The following takes a multi-cabin ship far away from the coastline as an example to illustrate the embodiments and realization principles of the present invention.

As shown in FIG. 1 , a schematic diagram of a multi-space scene in an embodiment of the present invention is shown, which is used to represent the layout of the interior of the ship. In this embodiment, the ship includes a corridor and a plurality of cabins on both sides of the corridor, the corridor is used as the first space 11, the first space is a public space, and each cabin is used as a second space 12, that is, a non-public space. . A plurality of main lighting devices 13 are installed in the first space 11, at least one auxiliary lighting device 14 is installed in each second space 12, and each main lighting device 13 is communicatively connected to one or more auxiliary lighting devices 14, so that each lighting The device is within the signal transmission range to ensure the effectiveness of communication. Usually, each main lighting device is communicatively connected to the auxiliary lighting device that is adjacent to or close to it.

The main lighting device 13 is used to collect real-time image information in the first space 11 , and the real-time image information is, for example, that a person is located in the first space 11 , a person enters the second space 12 from the first space 11 , or a person enters the second space 12 from the second space 12 . Enter the first space 11 .

The real-time image information collected by the main lighting device 13 is associated with the identity data of the ship's personnel. Specifically, the main lighting device 13 is also communicatively connected to a control terminal, which stores the identity feature information of ship personnel, including face feature information and basic information, such as name, nationality, gender, or age, etc. Any one of the information or a combination of multiple types of information. Each person's identity feature information on the ship corresponds to a user ID, that is, the user terminal, the user ID and the person's identity feature information stored in the control terminal are in a corresponding relationship. It should be noted that the identity information of the ship personnel can be collected and entered into the system through the collection equipment when the ship personnel board the ship, such as cameras, fingerprint biometric collectors, document information collectors and other collection equipment, or through each ship. The staffed user terminal collects the identity feature information. Since the identity feature information collection technology is the prior art, it will not be repeated here.

The primary lighting device 13 is communicatively connected to one or more secondary lighting devices 14 to receive user IDs of ship personnel from the secondary lighting devices 14 . Specifically, the auxiliary lighting device 14 is connected in communication with the user terminal to collect user IDs of ship personnel. The auxiliary lighting device 14 transmits the collected user IDs of the ship personnel to the main lighting device 13 . The main lighting device 13 combines the real-time image information and the user ID to determine the space where the ship personnel are located. How the main lighting device 13 specifically determines the space where the ship personnel is located will be described in detail in the positioning method below. It should be noted that, the main lighting device 13 may also be directly connected to the user terminal for communication.

The user terminal may be a handheld terminal or a wearable terminal. The handheld terminal is, for example, a mobile terminal, a pad computer, or a notebook computer, and the wearable terminal is, for example, a wristband, a smart watch, and the like. In addition, the user terminal can not only be applied to input the identity information of the ship personnel, but also can be used for other life functions, such as: paying accounts, monitoring the physical status information of the ship personnel and other functions, because these functions are all existing technologies, Therefore, it will not be repeated.

The main lighting device 13 can be communicatively connected not only with the auxiliary lighting device 14 , but also with other main lighting devices. For example: a main lighting device in a ship corridor communicates with other main lighting devices in the corridor to receive real-time image information from other main lighting devices, and judges the various lighting devices in the corridor according to the real-time image information collected by itself and from other main lighting devices. The direction of travel of ship personnel, or the total number of ship personnel in the corridor.

Specifically, the main lighting device 13 performs face recognition on the ship personnel based on the real-time image information in the first space 11 , extracts the moving objects in the first space 11 according to the result information of the face recognition, and monitors the moving objects in the first space 11 . Movement in space 11 determines the direction of travel of the ship's personnel. In addition, the main lighting device 13 can determine the total number of personnel located in the first space 11 and the identity of each vessel personnel according to the result information of the face recognition and the identity feature information of the vessel personnel stored in the control terminal.

It should be noted that between the main lighting device and the auxiliary lighting device, between the main lighting device and the control terminal, between the main lighting device and the user terminal, between the main lighting device and the main lighting device, and between the auxiliary lighting device and the user terminal A wireless network can be used for communication connection between them, and the wireless network is, for example, a Bluetooth network, a WiFi network, a mobile communication network, a ZigBee network, an NB-IoT network, or a MavLink network, and so on.

In addition, the main lighting device and the auxiliary lighting device described in this embodiment may be positioning lighting devices with completely identical functions, that is, the main lighting device and the auxiliary lighting device are both devices with processing functions; or, the main lighting device The auxiliary lighting device and the auxiliary lighting device may also be devices with different functions. For example, the main lighting device is a device with a processing function, and the auxiliary lighting device is a device without a processing function, so that the positioning cost can be reduced.

As shown in FIG. 2 , a schematic flowchart of a method for locating persons in a multi-space scene according to an embodiment of the present invention is shown. In this embodiment, the multi-space scene is still set as a multi-cabin ship, and the personnel positioning method is applied to the main lighting device in the first space of the ship, and the positioning method specifically includes:

S21: Collect real-time image information in the first space, and receive the user ID of the person from the auxiliary lighting device.

In this embodiment, the main lighting device collects image information of the ship personnel located in the first space, and the real-time image is used to identify the identity of the person and further locate the space where the person is located. The image information may be image information such as when the ship personnel are located in the first space, the ship personnel are not located in the first space, the ship personnel enter the second space from the first space, or the ship personnel enter the first space from the second space.

The main lighting device also receives the user ID of the person from the auxiliary lighting device, and the auxiliary lighting device obtains the user ID through the user terminal communicatively connected to it.

S22: Determine the location information of the person according to the real-time image information and the user ID; the location information includes information located in the first space or information located in the second space.

Preferably, the referenceability of the space where the person is located according to the real-time image information is higher than the space where the person is located according to the user ID. It should be noted that the main lighting device collects the real-time image information in the ship, that is, the image information of the user itself, while the auxiliary lighting device collects the information of the user terminal. Those skilled in the art need to take into account that, when the user is separated from the user terminal, the main lighting device and the auxiliary lighting device may detect user signals in two different spaces at the same time. The referability of the space where the person identified by the information is located is higher than that for identifying the space where the user is located according to the criterion of the space where the person identified by the user ID is located.

The following will illustrate how the main lighting device can identify the space where the person is located according to the real-time image information, and the referenceability of the space where the person is located is higher than the criterion for identifying the space where the person is located according to the user ID. For convenience of description, in the following embodiments, the real-time image information collected by the main lighting device is named the first signal, and the information collected by the auxiliary lighting device is named the second signal.

Embodiment 1: There are 6 people traveling in the corridor of the first space. The main lighting device set in the first space collects the first signal including the images of the 6 traveling people, and confirms the 6 traveling people based on the face recognition algorithm. The user ID of , because the face recognition algorithm is existing, so it will not be repeated here.

In this embodiment, if the second signal received by the main lighting device from the auxiliary lighting device does not include the user IDs of the six pedestrians, the main lighting device can determine the six pedestrians in combination with the first signal and the second signal. The marching personnel are now in the first space. If the second signal from the auxiliary lighting device received by the main lighting device includes the user IDs of the six pedestrians, the second signal of the auxiliary lighting device is contradictory with the first signal of the main lighting device, and the main lighting device according to The referenceability of the space where the persons identified by the real-time image information are located is higher than the criterion of the space where the persons identified according to the user ID are located, and it is recognized that the six users are located in the first space.

Example 2: There are 6 people traveling in the corridor of the first space. The main lighting device set in the first space collects the first signal including the images of the 6 traveling people, and confirms the 6 traveling people based on the face recognition algorithm. The user ID of , because the face recognition algorithm is existing, so it will not be repeated here.

In this embodiment, one of the six traveling personnel, for example, a ship personnel whose user ID is 587, enters cabin 001. Therefore, the image of ID.587 entering cabin 001 from the first space is collected by the main lighting device, and ID.587 is not included in the first signal collected by the main lighting device after ID.587 enters cabin 001.

The second signal received by the main lighting device from the auxiliary lighting device in cabin 001, if the second signal includes ID.587, the main lighting device can combine the first signal and the second signal to determine that ID.587 is located in cabin 001 middle. If the signal does not include ID.587, the second signal of the auxiliary lighting device contradicts the first signal of the main lighting device, and the reference of the space where the person is located according to the real-time image information identified by the main lighting device is higher than that according to the Based on the criteria for the space where the person identified by the user ID is located, it is determined that ID.587 is located in cabin 001.

It should be noted that in the case where the ship personnel enter the corridor from the cabin, it is also possible to determine which cabin the ship personnel are located in. The judgment principle is similar to the situation in which the ship personnel enter the cabin from the corridor, so it will not be repeated.

Embodiment 3: There are 6 people traveling in the corridor of the first space, and the main lighting device set in the first space collects the first signal including the images of the 6 traveling people through the image acquisition module. The main lighting device confirms the user IDs of the six traveling personnel based on the face recognition algorithm through the processing module.

In this embodiment, one of the six traveling personnel, for example, a ship personnel whose user ID is 487, enters cabin 001. Therefore, the image of ID.487 entering cabin 001 from the first space is collected by the main lighting device, and ID.487 is not included in the first signal collected by the main lighting device after ID.487 enters cabin 001.

As shown in FIG. 3 , a schematic diagram of the layout of the interior of the ship in Embodiment 3 of the present invention is shown. Cabin 002 is adjacent to cabin 001. There are ship personnel with user ID 366 in cabin 002 and their user terminals are located within the collection range of the auxiliary lighting device in cabin 001. Therefore, the second signal sent by the auxiliary lighting device in cabin 001 to the main lighting device may only include the information of the user terminal in cabin 001, or may include both the information of the user terminal in cabin 001 and cabin 002. User terminal information. That is, the second signal from the auxiliary lighting device in cabin 001 received by the main lighting device may only include ID.487, or may include both ID.487 and ID.366.

The primary lighting device combines the first signal and the second signal from the secondary lighting device in cabin 001 to determine the location information of user ID.487. Specifically, if the second signal from the auxiliary lighting device in cabin 001 only includes ID.487, the main lighting device can determine that ID.487 is located in cabin 001 in combination with the first signal and the second signal; if it comes from cabin 001 The second signal of the secondary lighting device includes both ID.487 and ID.366, then the main lighting device can determine the location information of the user ID.487 according to any one or a combination of the following methods. The judgment method is as follows:

Method 1) The main lighting device is located in cabin 002 according to the user ID.366, and ID.366 in the second signal of the auxiliary lighting device in cabin 001 is excluded. Since the first signal includes the real-time image information of user ID.487 entering cabin 001, and the second signal includes ID.487, it is determined by combining the first signal and the second signal of the auxiliary lighting device in cabin 001 that user ID.487 is located at in cabin 001.

Method 2) The main lighting device determines that user ID.487 is located in cabin 001 according to the signal strengths of different user terminals in the second signal, such as RSSI values, or parameters such as energy feedback indicators. The RSSI refers to the ReceivedSignal Strength Indication, which means the received signal strength indication, which is used to determine the link quality and whether to increase the broadcast transmission strength.

For example, since ID.487 is actually located in cabin 001 and ID.366 is located in cabin 002, the signal of the user terminal corresponding to ID.487 received by the auxiliary lighting device in cabin 001 must be stronger than ID. According to the signal of the user terminal corresponding to 366, it can be determined that user ID.487 is located in cabin 001. Therefore, the location information of the ship user can be indirectly determined according to the signal strength.

It should be noted that the above two judging methods can be used independently, or can be used in combination according to different weight ratios, which are not limited in the present invention. In addition, after excluding the identity information of other personnel, if there is still interference from the identity information of the adjacent cabin personnel, the first or second embodiment can be used for reference. Interference is eliminated according to the criteria of the space where the person identified by the user ID is located.

Embodiment 4: There are 6 people traveling in the corridor of the first space, and the main lighting device arranged in the first space collects the first signal including the images of the 6 traveling people through the image acquisition module. The main lighting device confirms the user IDs of the six traveling personnel based on the face recognition algorithm through the processing module.

In this embodiment, many of the six traveling personnel enter different cabins, for example, user ID.678 and user ID.688 enter cabins 003 and 004, respectively. Therefore, the main lighting device collects the image of user ID.678 entering cabin 003 from the first space and the image of user ID.688 entering cabin 004 from the first space, and entering the cabin at user ID.678 and user ID.688 respectively After cabins 003 and 004, the first signal collected by the main lighting device does not include user ID.678 and user ID.688.

As shown in FIG. 4 , a schematic diagram of the layout of the interior of the ship in Embodiment 4 of the present invention is shown. In the figure, the auxiliary lighting device in cabin 003 is named auxiliary lighting device 141, and the auxiliary lighting device in cabin 004 is named auxiliary lighting device 142. The detection area of the auxiliary lighting device 141 covers at least cabins 003 and 004, and the detection area of the auxiliary lighting device 142 also covers at least cabins 003 and 004; that is, the second signal collected by the auxiliary lighting device 141 may only It includes the information of the user terminals in the 003 cabin, and may include both the information of the user terminals in the 003 cabin and the information of the user terminals in the 004 cabin; the second signal collected by the auxiliary lighting device 142 may only include the information in the 004 cabin. The information of the user terminal may also include both the information of the user terminal in the 004 cabin and the information of the user terminal in the 003 cabin. Both the auxiliary lighting device 141 and the auxiliary lighting device 142 are connected to the main lighting device in communication, that is, the second signal from the auxiliary lighting device 141 received by the main lighting device may only include ID.678, or may include both ID.678 and ID. .688; the second signal from the auxiliary lighting device 142 received by the main lighting device may include only ID.688, or may include both ID.678 and ID.68. It should be noted that this embodiment is based on the case that each user terminal is in normal operation.

If the second signal of the auxiliary lighting device 141 only includes ID.678, and the second signal of the auxiliary lighting device 142 only includes ID.688, the main lighting device combines the first signal collected by itself and the second signal of the auxiliary lighting device 141 The second signal, and the second signal of the secondary lighting device 142, may determine that the user of ID.678 is located in cabin 003 and the user of ID.688 is located in cabin 004.

If the second signal of the auxiliary lighting device 141 includes both ID.678 and ID.688, and the second signal of the auxiliary lighting device 142 also includes ID.678 and ID.688, the main lighting device combines the The first signal, the second signal of the auxiliary lighting device 141, and the second signal of the auxiliary lighting device 142 determine the location information of the user according to any one of the following methods or a combination of multiple methods.

Method 1) The main lighting device determines the location information of the user according to the first signal, the signal strength of different user terminals in the second signal of the auxiliary lighting device 141 , and the signal strength of different user terminals in the second signal of the auxiliary lighting device 142 . This method can be summarized as a distance difference judgment method, which is used to judge the parameters of signal strength, for example, the RSSI value of the signal or the energy feedback index or the combination of the RSSI value and the energy feedback index can be used.

For example: if in the second signal collected by the auxiliary lighting device 141, the signal of the user terminal corresponding to ID.678 is stronger than the signal of the user terminal corresponding to ID.688, then the main lighting device will be based on the first signal and the signal of the auxiliary lighting device 141. The second signal may determine that the user of ID.678 is located in cabin 003. If, in the second signal collected by the auxiliary lighting device 142, the signal of the user terminal corresponding to ID.688 is stronger than the signal of the user terminal corresponding to ID.678, the main lighting device will use the first signal and the second signal of the auxiliary lighting device 142 according to the first signal and the second signal of the auxiliary lighting device 142. The signal determines that the user of ID.688 is in cabin 004.

Method 2) The primary lighting device determines the user's location information.

This method can be summarized as a time judgment method. The auxiliary lighting device scans the user terminals in its coverage area, and it takes a certain period of time from collection to receiving the feedback signal, and due to the distance between the user terminal in the coverage area and the auxiliary lighting device There are lengths, so the signal feedback time of the user terminal closer to the auxiliary lighting device is shorter, and the signal feedback time of the user terminal farther away from the auxiliary lighting device is longer.

For example: the auxiliary lighting device 141 collects the user terminal corresponding to ID.678 and the user terminal corresponding to ID.688 in the coverage area, and the signal feedback time of the user terminal corresponding to ID.678 is shorter than that of the user terminal corresponding to ID.688 Signal feedback is time-consuming. The main lighting device can determine that the user of ID.678 is located in the 003 cabin according to the time difference between the two feedbacks and the first signal. Similarly, the auxiliary lighting device 142 collects the user terminal corresponding to ID.688 and the user terminal corresponding to ID.678 in the coverage area, and the signal feedback time of the user terminal corresponding to ID.688 is shorter than that of the user terminal corresponding to ID.678 The signal feedback time-consuming. The main lighting device can determine that the user of ID.688 is located in the 004 cabin according to the time difference between the two feedbacks and the first signal.

Method 3) The main lighting device collects the real-time image of the user with ID.678 entering cabin 003, and performs face recognition on the user with ID.678, so as to determine that the user with ID.678 is located in cabin 003; The user with ID.678 collected by the lighting device leaves cabin 003 and enters the first space, and the main lighting device performs face recognition on the user with ID.678, so as to determine that the user with ID.678 is located in the first space. Similarly, the main lighting device collects the real-time image of the user with ID.688 entering cabin 004, and performs face recognition on the user with ID.688, so as to determine that the user with ID.688 is located in cabin 004; The user whose ID.688 is collected by the lighting device leaves cabin 004 and enters the first space. The main lighting device performs face recognition on the user with ID.688 to determine that the user with ID.688 is located in the first space. This method can be summarized as an access judgment method, and the above-mentioned Embodiments 1 to 3 have exemplified the judgment method in detail, and will not be repeated here.
