Description

Technical Field

[0001] This application relates to the field of AR glasses technology, and in particular to an escort system and method based on AR+AI glasses. Background Technology

[0002] Currently, escorting officers outside the police station uses a handheld police terminal combined with a body camera and electronic ankle monitor. Both the handheld terminal and the body camera need to be worn by the officers and operated separately, which is cumbersome in practice, hindering the freeing of their hands. Furthermore, some alarm information and timely communication messages cannot be received and processed immediately. This method has the following drawbacks:

[0003] 1. Traditional handheld police terminals combined with body cameras require police officers to operate them separately, which makes the operation process cumbersome, restricts the freedom of their hands, and affects law enforcement efficiency.

[0004] 2. Existing law enforcement recorders still lack integration of intelligent functions, making it difficult to meet the law enforcement needs in different scenarios and unable to provide law enforcement officers with comprehensive monitoring and data analysis capabilities.

[0005] 3. Some law enforcement recorders use a single communication method, which cannot achieve efficient data transmission and real-time communication, affecting the timely processing of law enforcement information and decision-making. Summary of the Invention

[0006] The purpose of this application is to overcome the problems of cumbersome operation, limited functionality, and single communication method of existing law enforcement recorders, and to provide an escort system and method based on AR+AI glasses.

[0007] Firstly, an AR+AI glasses-based escort system is provided, including:

[0008] AR glasses are used to acquire real-time video data, the wearer's real-time location, bind electronic ankle straps, generate virtual information through the lenses and overlay it with the real-world scene, and achieve PWL communication with the back-end control center. The relevant information includes real-time location information, electronic ankle strap wearer information, and distance information.

[0009] Electronic ankle straps are used to obtain the wearer's real-time location, restrict the wearer's behavior according to control commands, and achieve binding with AR glasses;

[0010] Indoor high-precision positioning base station, used to achieve indoor positioning of AR glasses;

[0011] The back-end control center is used to obtain the real-time location of the electronic ankle monitor and AR glasses.

[0012] In some possible implementations, the AR glasses include an AR glasses body and an AI control box, with the AR glasses body and the AI ​​control box connected by a detachable data cable.

[0013] In some possible implementations, the AR glasses body includes an eyeglass frame and an AR lens, a stabilized camera, a directional microphone, a speaker, a wear sensor, and a nine-axis gyroscope sensor mounted on the eyeglass frame. The AR lens, stabilized camera, directional microphone, speaker, wear sensor, and nine-axis gyroscope sensor are all electrically connected to the AI ​​control box via data cables.

[0014] In some possible implementations, the directional microphone includes a first directional microphone for voice control and a second directional microphone for collecting ambient sound. Both the first and second directional microphones are electrically connected to a voice processing chip, which is used for voice recognition and noise reduction of the sound signal. The voice processing chip is electrically connected to an AI control box via a data cable.

[0015] In some possible implementations, the AR lens includes a binocular array waveguide display lens and a microdisplay mounted on an eyeglass frame. Both the binocular array waveguide display lens and the microdisplay are electrically connected to an AI control box via data cables. The microdisplay is used to project digital information onto the binocular array waveguide display lens.

[0016] In some possible implementations, the AR glasses body also includes a light sensor and a fill light module mounted on the glasses frame, both of which are electrically connected to the AI ​​control box via a data cable.

[0017] In some possible implementations, the AI ​​control box includes an AI chip and a storage module connected to the AI ​​chip, a Beidou high-precision positioning module, an AOA high-precision positioning module, a UWB high-precision positioning module, a 4G communication module, a 5G communication module, a PWL police Wifi module, a Bluetooth module, a heat dissipation module, a roller operation module, and a rechargeable battery.

[0018] In some possible implementations, the heat dissipation module includes a cooling fan and at least one temperature sensor disposed within the AI ​​control box, both of which are electrically connected to the AI ​​chip.

[0019] Secondly, a method for escorting prisoners outside the home based on AR+AI glasses is provided for use with the system described in the first aspect, including:

[0020] The electronic ankle bracelet is fastened to the wrist or ankle of the detainee;

[0021] The AR glasses worn by the staff are then bound to the electronic ankle straps.

[0022] Input the escort mission information into the AR glasses and start the mission;

[0023] After the task begins, the AR glasses obtain their own location and the location of the attached electronic ankle strap in real time and can display it on the AR glasses. If the distance between the AR glasses and the electronic ankle strap exceeds a preset threshold, the AR glasses will issue an alarm to alert the staff.

[0024] The location data of the AR glasses and electronic ankle monitor is transmitted to the backend control center via 4G, 5G, or PWL until the task is completed.

[0025] In some possible implementations, AR glasses automatically determine whether they are outdoors based on the acquired real-time video data. If they are outdoors, the AR glasses use the BeiDou satellite for positioning; if they are indoors, the AR glasses use UWB and AOA for positioning.

[0026] This application has the following beneficial effects:

[0027] 1. The escort system proposed in this application can utilize AR glasses to achieve the functions of a law enforcement recorder. Staff can directly control the AR glasses via voice, and the AR glasses will display the corresponding operation functions in real time according to the voice input commands, thus eliminating the need for traditional gesture operation and freeing up the hands. The AR glasses can also be used to achieve functions such as positioning, shooting real-time video, and viewing the location of the attached electronic ankle bracelet at any time. When a detainee wearing an electronic ankle bracelet attempts to escape, it can not only automatically trigger an alarm, but also allow the AR glasses to view the detainee's location in real time for easy pursuit. Communication can use the PWL police network, and after encrypted transmission, it can be directly connected to the public security network. When escorting detainees, police officers only need to wear AR glasses to efficiently complete positioning, communication, and operation tasks, greatly simplifying the workflow and improving law enforcement efficiency and security.

[0028] 2. The escort method described in this application enables the binding of AR glasses and electronic ankle bracelets. After binding, the AR glasses can view the location information of the electronic ankle bracelets in real time. Once the distance between the electronic ankle bracelets and the AR glasses exceeds a certain value, the AR glasses can automatically issue an alarm to prompt the staff wearing the AR glasses to take timely action. The back-end control center can also know the real-time location of the staff and the detainees, and can automatically identify the current scene and automatically switch the corresponding positioning method according to the current scene. Whether outdoors or indoors, the high-precision positioning information of the AR glasses can be obtained, making the entire escort process traceable and greatly reducing the risk of detainees escaping.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figure 1 As shown in Embodiment 1 of this application, an escort system based on AR+AI glasses is included, comprising AR glasses 100, electronic ankle strap 200, indoor high-precision positioning base station 300, and a back-end control center 400. The AR glasses 100 are used to acquire real-time video data, acquire real-time voice, acquire the wearer's real-time location, bind the electronic ankle strap 200, generate virtual information from the electronic ankle strap 200 through the lenses and overlay it onto the real-world scene, and achieve PWL communication with the back-end control center 400. The relevant information includes real-time location information, electronic ankle strap 200 wearer information, and distance information. The electronic ankle strap 200 is used to acquire the wearer's real-time location, restrict the wearer's behavior according to control commands, and bind to the AR glasses 100. The indoor high-precision positioning base station 300 is used to achieve indoor positioning of the AR glasses 100. The back-end control center 400 is used to acquire the real-time locations of the electronic ankle strap 200 and the AR glasses 100 to achieve back-end monitoring.

[0044] like Figure 2 As shown, the AR glasses 100 includes an AR glasses body 101 and an AI control box 102. The AR glasses body 101 and the AI ​​control box 102 are connected by a detachable data cable. The AR glasses 100 can transmit collected video data, voice data, etc. to the AI ​​control box 102 through the data cable. At the same time, the AI ​​control box 102 can transmit control signals, display data, etc. to the AR glasses body 101.

[0045] like Figure 3 and Figure 4As shown, the AR glasses body 101 includes a glasses frame 1011 and an AR lens 1012, a stabilized camera 1013, a directional microphone 1014, a speaker 1015, a wear sensor 1016, a nine-axis gyroscope sensor 1017, a light sensor 1018, and a fill light module 1019 mounted on the glasses frame 1011. The AR lens 1012, stabilized camera 1013, directional microphone 1014, speaker 1015, wear sensor 1016, nine-axis gyroscope sensor 1017, light sensor 1018, and fill light module 1019 are all electrically connected to the AI ​​control box 102 via data cables. The stabilized camera 1013 is used to capture video footage. The speaker 1015 is used to play sounds, including alarm sounds, prompt sounds, and human-computer dialogue. The wear sensor 1016 is set on the nose pad of the glasses frame 1011 to detect whether the AR glasses 100 is being worn. The nine-axis gyroscope sensor is used to detect the direction of movement of the AR glasses 100 wearer. The light sensor 1018 is used to detect the brightness of the ambient light and automatically adjusts the brightness of the image on the binocular array waveguide display lens 10121 according to the brightness, so that the AR glasses 100 can recognize information more clearly. In low light, it controls the supplementary light module 1019 to work to provide supplementary light for the shooting of the image-stabilized camera 1013. The directional microphone 1014 includes a first directional microphone for voice control. The system includes a microphone 10141 and a second directional microphone 10142 for collecting ambient sound. Both the first and second directional microphones 10141 and 10142 are electrically connected to a voice processing chip. The voice processing chip is used for voice recognition and noise reduction of sound signals. The voice processing chip is electrically connected to the AI ​​control box 102 via a data cable. In use, the first directional microphone 10141 can record and recognize character voices, so that users who have not recorded character voices cannot control the AR glasses 100 by voice. The AR lens 1012 includes a binocular array waveguide display lens 10121 and a microdisplay 10122 mounted on the eyeglass frame 1011. Both the binocular array waveguide display lens 10121 and the micro-display screen 10122 are electrically connected to the AI ​​control box 102 via data cables. The micro-display screen 10122 is used to project digital information onto the binocular array waveguide display lens 10121. The micro-display screen 10122 is a micro-LED / OLED micro-display screen 10122. The binocular array waveguide display lens 10121 is used to display information. The micro-LED / OLED micro-display screen 10122 is installed at the left and right corners of the eyeglass frame 1011. The digital information of the micro-LED / OLED micro-display screen 10122 can be projected onto the binocular array waveguide display lens 10121.

[0046] like Figures 5-7As shown, the AI ​​control box 102 includes an AI chip 1032 and connected to the AI ​​chip 1032 are a storage module 1021, a Beidou high-precision positioning module 1022, an AOA high-precision positioning module 1023, a UWB high-precision positioning module 1024, a 4G communication module 1025, a 5G communication module 1026, a PWL police Wi-Fi module 1027, a Bluetooth module 1028, a heat dissipation module 1029, a roller operation module 1030, and a rechargeable battery 1031. The storage module 1021 is used to store data such as video, audio, and images. The Beidou high-precision positioning module 1022... 022 is used to achieve high-precision outdoor positioning in conjunction with BeiDou satellite 500. AOA high-precision positioning module 1023 includes an AOA chip and an AOA antenna, used to establish a communication connection with the AOA base station and receive positioning information. UWB high-precision positioning module 1024 includes a UWB chip and a UWB antenna, used to establish a communication connection with the UWB base station and receive positioning information. AOA high-precision positioning module 1023 and UWB high-precision positioning module 1024 are used in conjunction with the AOA and UWB indoor high-precision positioning base station 300 to achieve high-precision indoor positioning. PWL police Wi-Fi module 10... 27 includes a WIFI chip and antenna for establishing a wireless communication connection with the PWL base station; a 4G communication module 1025, a 5G communication module 1026, and a PWL police WIFI module 1027 for combining with the communication base station 600 to achieve 4G, 5G, and PWL communication; a roller operation module 1030 for operating the key; a rechargeable battery 1031 for providing power; a Bluetooth module 1028 for enabling Bluetooth connection with other devices; and a heat dissipation module 1029 including a cooling fan 10291 and at least one temperature sensor 10292 disposed within the AI ​​control box 102. Both the temperature sensor 10292 and the cooling fan 10291 are electrically connected to the AI ​​chip 1032. The temperature sensor 10292 can detect the temperature inside the AI ​​control box 102. The AI ​​chip 1032 can automatically control the operation of the cooling fan 10291 according to the temperature, and the speed of the cooling fan 10291 increases as the temperature rises. The AI ​​chip 1032 can ensure that it processes a large amount of audio and video data and other data from the AR glasses body 101 with low power consumption, and at the same time, it returns the data to the AR glasses body 101 and displays it on the binocular array waveguide display lens 10121.

[0047] When there is an escort mission, after the detainee completes the exit procedures, the police officer selects an available electronic ankle bracelet (200) and fastens it to the detainee's wrist or ankle. The officer then logs into the police APP through AR glasses (100), searches for the electronic ankle bracelet (200), and binds it. After successful binding, the electronic ankle bracelet (200) will emit a prompt sound, and the AR glasses (100) will display a successful binding message. After successful binding, the officer enters the relevant mission information and begins the mission. A binding relationship is then established between the officer's AR glasses (100) and the detainee's electronic ankle bracelet (200) during the mission. During the process, if the police officer and the detainee exceed the predetermined distance, the AR glasses 100 worn by the police officer will issue an alarm, alerting both the police officer and the detainee. Outdoors, the AR glasses 100 can use Beidou positioning for outdoor positioning. Indoors, the UWB / AOA high-precision positioning module inside the AR glasses 100, combined with the UWB / AOA high-precision positioning base station, can output high-precision indoor coordinates and send the coordinates to the backend via 4G / 5G / PWL. The backend can then know the real-time location of the police officer and the detainee.

[0048] In this embodiment, during escort operations, police officers can use AR glasses 100 to record audio and video using a law enforcement recorder. Staff can directly control the AR glasses 100 via voice, and the AR glasses 100 will display the corresponding operation function in real time based on the voice input, thus eliminating the need for traditional gesture controls and freeing up their hands. The AR glasses 100 can also be used for location tracking, real-time video recording, and monitoring the location of the attached electronic ankle bracelet 200. If a detainee wearing the electronic ankle bracelet 200 attempts to escape, the system will not only automatically issue an alarm but also detect the electronic ankle bracelet attached to the AR glasses 100. The location information of the detainee is displayed in real time on the AR glasses 100. Even through walls or other obstacles, the police can see the detainee behind the obstacles on the AR glasses 100. The police can achieve a "see-through" effect when searching for the detainee. The AR glasses 100 can be used to view the location of the detainee in real time, which is convenient for pursuit. Moreover, the police are less likely to be shaken off during the pursuit. Communication can use the PWL police network. After encrypted transmission, it is directly connected to the public security network. When escorting detainees, the police only need to wear AR glasses 100 to efficiently complete positioning, communication and operation tasks, which greatly simplifies the workflow and improves law enforcement efficiency and safety.

[0049] Example 2

[0050] like Figure 8 As shown, the AR+AI glasses-based escort system device according to Embodiment 2 of this application includes:

[0051] S100. After the detainee has completed the release procedures, the police officer will select an available electronic ankle bracelet 200 and fasten it to the detainee's wrist or ankle.

[0052] S200: Police officers log into the police APP through AR glasses 100, search for the electronic ankle bracelet 200, and complete the binding between AR glasses 100 and electronic ankle bracelet 200. After successful binding, electronic ankle bracelet 200 will emit a prompt sound, and AR glasses 100 will also display a successful binding display.

[0053] After successfully binding the S300, input the escort mission information into the AR glasses 100 and start the mission.

[0054] S400. After the mission begins, the AR glasses 100 obtains its own location and the location of the bound electronic ankle strap 200 in real time and displays it on the AR glasses 100. If the distance between the AR glasses 100 and the electronic ankle strap 200 exceeds a preset threshold, the AR glasses 100 will issue an alarm to alert the staff. For example, if the preset threshold is 5m, and the distance between the detainee wearing the electronic ankle strap 200 and the police officer wearing the AR glasses 100 exceeds 5m, the AR glasses 100 will issue a voice alarm and display the location information of the detainee on the lens. If the police officer is facing the direction of the detainee, a red dot marked with the distance will be seen on the AR glasses 100, which represents the detainee. If the police officer is not facing the direction of the detainee, an arrow will be seen on the AR glasses 100 to indicate the direction of the detainee.

[0055] S500 transmits the real-time location data of AR glasses 100 and electronic ankle strap 200 to the backend control center 400 via 4G, 5G, or PWL until the task is completed.

[0056] To improve positioning accuracy, the AR glasses 100 automatically determines whether it is outdoors based on the acquired real-time video data. If it is outdoors, the AR glasses 100 uses the BeiDou 500 satellite for positioning; if it is indoors, the AR glasses 100 uses UWB and AOA for positioning.

[0057] In this embodiment, the AR glasses 100 and the electronic ankle strap 200 can be bound together. After binding, the AR glasses 100 can view the location information of the electronic ankle strap 200 in real time. Once the distance between the electronic ankle strap 200 and the bound AR glasses 100 exceeds a certain value, the AR glasses 100 can automatically issue an alarm to prompt the staff wearing the AR glasses 100 to handle the situation in time. The background control center 400 can also know the real-time location of the staff and the detainees, and can automatically identify the current scene and automatically switch the corresponding positioning method according to the current scene. Whether outdoors or indoors, the high-precision positioning information of the AR glasses 100 can be obtained, making the entire escort process traceable and greatly reducing the risk of the detainees escaping.

[0058] It should be noted that other specific implementations of the escort system device based on AR+AI glasses in this embodiment can be found in the above-described specific implementations of the escort system based on AR+AI glasses. To avoid redundancy, they will not be repeated here.

[0059] The above are merely preferred embodiments of this application; however, the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
