Description

Technical Field

[0001] This application relates to the field of intelligent transportation technology, and in particular to a method, apparatus, device and medium for determining vehicle information. Background Technology

[0002] Electronic fence systems are products specifically designed for public safety applications. They feature real-time data collection capabilities, including video capture, and the acquisition of information such as IMSI (International Mobile Subscriber Identity) and MAC (Main Address) from fast-moving mobile terminals. Through AI (Artificial Intelligence) image analysis, the collected vehicle and passenger information can be matched to provide timely warnings of key personnel, ensuring public safety. However, in related technologies, the electronic capture process in electronic fence systems can be affected by interference from other terminals, leading to inaccurate passenger identification and consequently, inaccurate person-vehicle matching. This results in a low matching rate for critical vehicle information and an inability to accurately determine vehicle details. Summary of the Invention

[0003] This application provides a method, apparatus, device, and medium for determining vehicle information, in order to solve the problem of low matching rate of key vehicle information during electronic capture and inability to accurately determine vehicle information.

[0004] In a first aspect, embodiments of this application provide a method for determining vehicle information, the method comprising:

[0005] When a vehicle to be matched is detected in the target fence area, the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the time of capture of the vehicle to be matched are obtained; the target fence area is a common collection area of ​​multiple fence devices;

[0006] For any one of the plurality of fence devices, determine the IMSI information set corresponding to that fence device; wherein, the IMSI information set corresponding to that fence device includes the IMSI information of the terminal device connected to that fence device at the time of data collection;

[0007] Based on the IMSI information set corresponding to each fence device, determine the target IMSI information;

[0008] The target IMSI information, the license plate information, and the facial information are used as the vehicle information of the vehicle to be matched.

[0009] Based on the above scheme, by collecting IMSI information from terminal devices in the common collection area of ​​multiple fence devices, the information of passengers can be accurately determined, thereby effectively improving the matching rate of key vehicle information in the electronic capture process and thus accurately determining vehicle information.

[0010] In one possible implementation, after determining the IMSI information set corresponding to any one of the fence devices, the method further includes:

[0011] Disconnect the fence device from the terminal device connected to the fence device at the time of data collection; and prohibit the fence device from connecting to the terminal device before determining the target IMSI information.

[0012] Based on the above scheme, by disconnecting the connection between the fence device and the terminal device after determining the IMSI information set corresponding to each fence device, it can be ensured that the terminal device will not connect to that fence device next time, but will connect to other fence devices. This ensures that a terminal device can be connected to multiple fence devices.

[0013] In one possible implementation, determining the target IMSI information based on the IMSI information set corresponding to each fence device includes:

[0014] The IMSI information that is the same in the IMSI information set corresponding to each fence device is taken as the target IMSI information.

[0015] Based on the above scheme, the IMSI information of passengers in vehicles to be matched within the target fence area can be accurately determined.

[0016] In one possible implementation, the method further includes:

[0017] Before using each of the fencing devices, determine the collection area of ​​each fencing device.

[0018] In one possible implementation, determining the collection area of ​​each fence device includes:

[0019] When a companion device is detected in the target fence area and the companion device is connected to each fence device, the angle of the directional antenna of each fence device is adjusted in multiple rounds until the target angle of the directional antenna of each fence device is determined. Then, the area covered by the target angle of each fence device is taken as the collection area of ​​each fence device.

[0020] After each round of angle adjustment, the following process is performed:

[0021] Obtain the cell information of each fence device and the cell information of the companion device connected at any position in the target fence area; if the cell information of the companion device connected at any position in the target fence area includes the cell information of each fence device, then the angle adjusted in this round is taken as the target angle of the directional antenna of each fence device.

[0022] Based on the above scheme, the coverage area of ​​each fence device can be determined by adjusting the angle of the directional antenna of each fence device in multiple rounds, thereby ensuring that each fence area can collect information on the vehicles to be matched and the passengers in the vehicles to be matched in the target fence area.

[0023] In one possible implementation, after determining the collection area of ​​each fence device, the method further includes:

[0024] Disconnect each fence device from the accompanying testing device; and prohibit each fence device from connecting to the accompanying testing device before the collection areas of the multiple fence devices are determined.

[0025] Based on the above scheme, by disconnecting the fence device from the accompanying device after determining the collection area of ​​each fence device, it can be ensured that the accompanying device will not connect to the fence device in the next instance, but will connect to other fence devices. This ensures that one accompanying device can be connected to multiple fence devices, thereby determining the collection area of ​​multiple fence devices.

[0026] Secondly, this application provides a vehicle information determination device, the device comprising:

[0027] The acquisition module is used to acquire the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the time of capture when the vehicle to be matched is detected in the target fence area; the target fence area is a common acquisition area of ​​multiple fence devices.

[0028] The determination module is used to determine the IMSI information set corresponding to any one of the plurality of fence devices; wherein, the IMSI information set corresponding to any one fence device includes the IMSI information corresponding to the terminal device connected to the any one fence device at the time of data collection; and determine the target IMSI information based on the IMSI information set corresponding to each fence device.

[0029] The matching module is used to use the target IMSI information, the license plate information, and the facial information as the vehicle information of the vehicle to be matched.

[0030] In one possible implementation, the device further includes:

[0031] The connection module is used to disconnect the fence device from the terminal device connected to the fence device at the time of data collection after determining the IMSI information set corresponding to any one of the fence devices; and to prohibit the fence device from connecting to the terminal device before determining the target IMSI information.

[0032] In one possible implementation, the determining module is specifically used to take the same IMSI information from the IMSI information set corresponding to each fence device as the target IMSI information.

[0033] In one possible implementation, the device further includes:

[0034] The area determination module is used to determine the collection area of ​​each fence device before using each fence device.

[0035] In one possible implementation, the region determination module is specifically used for:

[0036] When a companion device is detected in the target fence area and the companion device is connected to each fence device, the angle of the directional antenna of each fence device is adjusted in multiple rounds until the target angle of the directional antenna of each fence device is determined. Then, the area covered by the target angle of each fence device is taken as the collection area of ​​each fence device.

[0037] After each round of angle adjustment, the following process is performed:

[0038] Obtain the cell information of each fence device and the cell information of the companion device connected at any position in the target fence area; if the cell information of the companion device connected at any position in the target fence area includes the cell information of each fence device, then the angle adjusted in this round is taken as the target angle of the directional antenna of each fence device.

[0039] In one possible implementation, the connection module is further configured to disconnect the connection between each fence device and the accompanying testing device after the collection area of ​​each fence device is determined; and to prohibit the connection between each fence device and the accompanying testing device before the collection areas of the multiple fence devices are all determined.

[0055] Electronic fence systems are products specifically designed for public safety applications. They feature real-time data collection capabilities, including video capture, and the acquisition of information such as IMSI (International Mobile Subscriber Identity) and MAC (Main Address) from fast-moving mobile terminals. Through AI (Artificial Intelligence) image analysis, the collected vehicle and passenger information can be matched to provide timely warnings of key personnel, ensuring public safety. However, in related technologies, the electronic capture process in electronic fence systems can be affected by interference from other terminals, leading to inaccurate passenger identification and consequently, inaccurate person-vehicle matching. This results in a low matching rate for critical vehicle information and an inability to accurately determine vehicle details.

[0056] The electronic fence device obtains the mobile phone's IMSI (Indicator Feature Code) information by triggering the mobile phone's TAU (Tracking Area Update) and receiving the location information update signaling.

[0057] In view of this, this application provides a method, apparatus, device and medium for determining vehicle information, in order to solve the problem of low matching rate of key vehicle information in the electronic capture process, which makes it impossible to accurately determine vehicle information.

[0058] The inventive concept of this application embodiment can be summarized as follows: When a vehicle to be matched is detected in the target fence area, this application embodiment acquires the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the acquisition time of capturing the vehicle to be matched; for any one of the multiple fence devices, the IMSI information set corresponding to any one fence device is determined; based on the IMSI information set corresponding to each fence device, the target IMSI information is determined; the target IMSI information, license plate information, and facial information are used as the vehicle information of the vehicle to be matched, which effectively improves the matching rate of key vehicle information in the electronic capture process, thereby accurately determining the vehicle information.

[0059] After introducing the main inventive concept of the embodiments of this application, the application scenario diagram of the vehicle information determination method provided by the embodiments of this application will be described below with reference to the accompanying drawings. Figure 1 As shown, the scenario includes a data acquisition device 101, a first fence device 102, a second fence device 103, and a server 104, wherein:

[0060] The data acquisition device 101 is a device with image acquisition capabilities, including electronic police equipment, electronic monitoring equipment, surveillance cameras, video recorders, and terminal devices with video acquisition capabilities (such as laptops, computers, mobile phones, and televisions). The data acquisition device 101 can send image information of vehicles to be matched within the target fence area to the server 104.

[0061] The first fence device 102 and the second fence device 103 are used to connect with the terminal devices in their respective collection areas, obtain the IMSI information of the terminal devices in their respective collection areas, and send it to the server 104 via the network. The terminal devices can be televisions, mobile phones, tablets, personal computers, etc.

[0068] It should be noted that the above Figure 1 The application scenarios shown and Figure 2 The server structure shown is merely an example, and the embodiments of this application do not limit it.

[0069] After introducing the application scenarios of the embodiments of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiments of this application provide method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on conventional or non-creative effort. In steps where there is no logically necessary causal relationship, the execution order of these steps is not limited to the execution order provided in the embodiments of this application.

[0070] See Figure 3 This is a flowchart illustrating a method for determining vehicle information provided in an embodiment of this application. Figure 3 As shown, the method includes the following steps:

[0071] In step 301, when a vehicle to be matched is detected in the target fence area, the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the capture time of the vehicle to be matched are obtained.

[0072] The target fence area is the common data collection area of ​​multiple fence devices.

[0073] In step 302, for any one of the multiple fence devices, the IMSI information set corresponding to that fence device is determined.

[0074] The IMSI information set corresponding to any one fence device includes the IMSI information of the terminal device connected to any fence device at the time of data collection. The fence device in this application can be installed at a traffic light intersection.

[0075] In one possible implementation, after determining the IMSI information set corresponding to any fence device in this embodiment, the connection between the fence device and the terminal device connected to the fence device at the time of data collection can be disconnected; and before determining the target IMSI information, the connection between the fence device and the terminal device is prohibited.

[0076] Based on the above scheme, by disconnecting the connection between the fence device and the terminal device after determining the IMSI information set corresponding to each fence device, it can be ensured that the terminal device will not connect to that fence device next time, but will connect to other fence devices. This ensures that a terminal device can be connected to multiple fence devices.

[0077] In step 303, the target IMSI information is determined based on the IMSI information set corresponding to each fence device; the target IMSI information, license plate information, and facial information are used as the vehicle information of the vehicle to be matched.

[0078] In one possible implementation, the target IMSI information is determined based on the IMSI information set corresponding to each fence device in this embodiment. Specifically, the same IMSI information in the IMSI information set corresponding to each fence device can be used as the target IMSI information.

[0079] For example, in Figure 4 The system includes data acquisition equipment, fencing equipment (fencing equipment 1 and fencing equipment 2), and the target acquisition area. The coverage areas of the directional antennas of fencing equipment 1 and fencing equipment 2, i.e., the acquisition areas, are as follows: Figure 4 The solid and dashed line areas are shown in the diagram. The target acquisition area is as follows: Figure 4 The area where the solid and dashed lines overlap is shown.

[0080] When the vehicle to be matched enters, such as Figure 4 When the solid and dashed lines in the image overlap, the acquisition device captures an image and performs license plate and passenger facial recognition. The captured license plate, facial information, and capture time are then immediately uploaded to the backend platform. Alternatively, the acquisition device continuously captures images of the target area and uploads each captured image to the backend platform. When the backend platform detects a vehicle to be matched within the target area, it acquires the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle, and the capture time of the vehicle to be matched.

[0081] Once the vehicle to be matched enters the target data collection area, because the signal strength of the fence device is much stronger than that of other cells it is currently connected to, the terminal devices within the coverage area of ​​the fence device will trigger cell reselection and connect to either fence device 1 or fence device 2. At this point, it is assumed that all terminal devices inside the vehicle to be matched, as well as terminal devices within the data collection area of ​​fence device 1 but outside the target data collection area, are connected to fence device 1. The IMSI information in the IMSI information set corresponding to fence device 1 at this time is M1, M2, M3, and M4. Then, the IMSI information and corresponding collection times of all terminal devices within the coverage area of ​​fence device 1 are obtained. Afterwards, the connection between fence device 1 and these terminal devices is disconnected, and the connection between fence device 1 and these terminal devices is prohibited until the target IMSI information is determined.

[0082] This will cause these terminal devices to fail to connect to a valid cell, and thus automatically rescan and select the optimal cell for connection. Since the terminal devices in the vehicle to be matched are simultaneously within the coverage area of ​​fence device 2 and have significantly stronger signals than other cell base stations, they will connect to the cell of fence device 2 after failing to connect to the cell of fence device 1. At the same time, terminal devices within the collection area of ​​fence device 2 but outside the target collection area will also connect to the cell of fence device 2. At this time, the IMSI information in the IMSI information set corresponding to fence device 2 will be M1, M2, M5, and M6. Then, the IMSI information and corresponding collection times of all terminal devices within the coverage area of ​​fence device 2 will be obtained. Afterwards, the connection between fence device 2 and these terminal devices will be disconnected, and the connection between fence device 2 and these terminal devices will be prohibited until the target IMSI information is determined.

[0083] Next, the intersection of the IMSI sets collected at the same collection time will be taken to obtain the target IMSI information M1 and M2. Finally, the target IMSI information M1 and M2 will be associated with the license plate information of the vehicle to be matched and the facial information of the passenger in the vehicle to be matched obtained at the same collection time as the vehicle information of the vehicle to be matched. In this way, all the key information of people and vehicles (IMSI information, face, license plate) will be collected.

[0084] For example, multiple terminal devices within the target fence area may not all be connected to the same fence device. Suppose M1 is connected to fence device 1 and M2 is connected to fence device 2. After collecting the corresponding IMSI information, the fence device will disconnect fence device 1 from M1 and prohibit the connection between fence device 1 and M1 before determining the target IMSI information. Similarly, it will disconnect fence device 2 from M2 and prohibit the connection between fence device 2 and M2 before determining the target IMSI information. Then, M1 will connect to fence device 2 and M2 will connect to fence device 1. Thus, the IMSI information set obtained by fence device 1 will contain M1 and M2, and the IMSI information set obtained by fence device 2 will contain M1 and M2. Taking the intersection of the IMSI sets collected at the same collection time, the target IMSI information M1 and M2 is obtained. Finally, the target IMSI information M1 and M2 are associated with the license plate information of the vehicle to be matched and the facial information of the passengers in the vehicle to be matched obtained at the same collection time as the vehicle information of the vehicle to be matched.

[0085] Based on the above scheme, by collecting IMSI information from terminal devices in the common collection area of ​​multiple fence devices, the IMSI information of passengers in the target fence area can be accurately determined, thereby effectively improving the matching rate of key vehicle information in the electronic capture process and thus accurately determining vehicle information.

[0086] In one possible implementation, the fencing device employs a directional antenna; the coverage area of ​​the directional antenna can be dynamically adjusted by rotating the pan-tilt unit horizontally and vertically. Since the directional antenna of the fencing device may be in any direction at the time of manufacture and may not cover the target fence area, continuous adjustment by the pan-tilt unit is necessary. Therefore, in this embodiment, the collection area of ​​each fencing device needs to be determined before use.

[0087] In one possible implementation, the collection area of ​​each fence device in this application embodiment can be determined in the following way:

[0088] When the accompanying device is detected in the target fence area and the accompanying device is connected to each fence device, the angle of the directional antenna of each fence device is adjusted in multiple rounds until the target angle of the directional antenna of each fence device is determined. Then, the area covered by each fence device at the target angle is taken as the collection area of ​​each fence device.

[0089] After each round of angle adjustment, the following process is performed: obtain the cell information of each fence device and the cell information connected to the accompanying device at any position in the target fence area; if the cell information connected to the accompanying device at any position in the target fence area includes the cell information of each fence device, then the angle adjusted in this round is taken as the target angle of the directional antenna of each fence device.

[0090] Among them, the test terminal can be a device with Wi-Fi and cellular wireless network functions, which can connect to the AP hotspot of the fence device and the cellular cell created by the base station at the same time.

[0091] In one possible implementation, after the collection area of ​​each fence device is determined, the connection between each fence device and the accompanying testing device can be disconnected; and before the collection areas of multiple fence devices are determined, the connection between each fence device and the accompanying testing device is prohibited.

[0092] In practice, the fence device can first set its built-in Wi-Fi module to AP mode for Wi-Fi connection with the test terminal. Assume fence device 1 creates Wi-Fi hotspot AP1 and fence device 2 creates Wi-Fi hotspot AP2. After defining the target fence area, the test terminal is placed within the target fence area.

[0093] Then, use the APP on the test terminal to scan for Wi-Fi hotspots. After scanning for AP hotspots created by nearby fence devices, randomly select one to connect to:

[0094] Assuming AP2 is selected initially, the system acquires the cell information and signal strength of the cell connected to the test terminal's cellular module, as well as the cell information created by fence device 2. If the cell information connected to the test device is not the cell information created by fence device 2, the angle of the directional antenna of fence device 2 is adjusted multiple times until the test device can connect to the cell information created by fence device 2 while continuously moving within the target fence area. The adjusted angle is then determined as the target angle of the directional antenna of fence device 2, and the area covered by fence device 2 at this target angle is taken as the acquisition area of ​​fence device 2. Once the target angle of fence device 2 is adjusted, the Wi-Fi and cellular connections between fence device 2 and the test terminal are disconnected, and connection between fence device 2 and the test device is prohibited. Then, the companion device connects to AP1 via Wi-Fi to obtain the cell information and signal strength of the cell module connected to by the companion terminal, as well as the cell information created by fence device 1. If it is found that the cell information connected to by the companion device is not the cell information created by fence device 1, the angle of the directional antenna of fence device 1 is adjusted multiple times until the companion device can connect to the cell information created by fence device 1 as it moves continuously in the target fence area. Then, the angle adjusted in this round is determined as the target angle of the directional antenna of fence device 1, and the area covered by fence device 1 at the target angle is taken as the collection area of ​​fence device 1.

[0095] Based on the above scheme, the coverage area of ​​each fence device can be determined by adjusting the angle of its directional antenna in multiple rounds. This ensures that each fenced area can collect information on the vehicles to be matched and the passengers in those vehicles within the target fenced area. Furthermore, by disconnecting the fence device from the accompanying testing device after determining its collection area, it can be ensured that the accompanying testing device will not connect to that fence device in the next iteration, but will instead connect to other fence devices. This allows a single accompanying testing device to be connected to multiple fence devices, thereby determining the collection areas of multiple fence devices.

[0096] Based on the foregoing description, when a vehicle to be matched is detected in the target fence area, this embodiment of the application acquires the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the capture time of the vehicle to be matched; for any one of the multiple fence devices, the IMSI information set corresponding to that fence device is determined; based on the IMSI information set corresponding to each fence device, the target IMSI information is determined; the target IMSI information, license plate information, and facial information are used as the vehicle information of the vehicle to be matched, which effectively improves the matching rate of key vehicle information in the electronic capture process, thereby accurately determining the vehicle information.

[0097] Based on the same inventive concept, embodiments of this application also provide a device for determining vehicle information. For example... Figure 5As shown, the device includes:

[0098] The acquisition module 501 is used to acquire the license plate information of the vehicle to be matched, the facial information of the passenger in the vehicle to be matched, and the acquisition time of capturing the vehicle to be matched when a vehicle to be matched is detected in the target fence area; the target fence area is a common acquisition area of ​​multiple fence devices.

[0099] The determining module 502 is used to determine the IMSI information set corresponding to any one of the plurality of fence devices; wherein, the IMSI information set corresponding to any one fence device includes the IMSI information corresponding to the terminal device connected to the any one fence device at the time of data collection; and determine the target IMSI information based on the IMSI information set corresponding to each fence device.

[0100] The matching module 503 is used to use the target IMSI information, the license plate information and the face information as the vehicle information of the vehicle to be matched.

[0102] The connection module is used to disconnect the fence device from the terminal device connected to the fence device at the time of data collection after determining the IMSI information set corresponding to any one of the fence devices; and to prohibit the fence device from connecting to the terminal device before determining the target IMSI information.

[0103] In one possible implementation, the determining module 502 is specifically used to take the same IMSI information from the IMSI information set corresponding to each fence device as the target IMSI information.
