Abstract
Description
Technical Field
[0001] The present invention relates to the field of case handling area management, and more specifically, to a case handling area management method and system based on ultra-wideband and face recognition. Background Art
[0002] At present, in the police handling area, there are usually two methods to locate the trajectory of people in the area. One is to use ultra-wideband technology and wireless bracelets for positioning, and the other is to use face recognition technology and face recognition equipment for positioning.
[0003] The wireless positioning solution of the wristband uses a wireless positioning wristband to bind to mobile targets such as criminal suspects and police officers to generate unique identification signal data. Through the network infrastructure composed of positioning tags, positioning base stations, and switches deployed in the corridors of the case handling area and various functional rooms, each positioning tag will be pre-configured with the associated video channel to locate the real-time location of the monitored object, and the video surveillance system background storage device will be linked to mark the video files of the associated cameras, so as to realize the integration and unified management of video recordings according to the suspect's movement trajectory.
[0004] The face recognition solution is that before entering the area, the personnel first perform face collection and registration on the entry tablet or the case handling center terminal. All rooms in the case handling area are equipped with access control switches and face capture tablets. When personnel enter each functional room, they need to take a human photo for recognition. If the recognition is passed, the access control is opened and the record of the personnel entering the functional room is added, thus generating the business track of the personnel in the case handling area.
[0005] However, both of the above solutions have certain disadvantages. The disadvantages of the wireless bracelet positioning solution are: lack of friendly interaction, no clear instructions for police officers to handle cases in a standardized manner; the bracelet positioning is not accurate enough, and there may be trajectory drift. The disadvantages of the face recognition solution are: the face recognition solution relies on tablets, and some areas of the case handling area cannot be equipped with tablets, resulting in missing trajectories. The trajectory of large areas cannot be accurately located, such as: passages, large functional rooms, etc.; there is a lack of real-time movement trajectories within the area. Summary of the invention

[0027] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] The following first describes in detail the case handling area management method based on ultra-wideband and face recognition according to an embodiment of the present invention with reference to the accompanying drawings.
[0029] like Figure 1 As shown, the case handling area management method based on ultra-wideband and face recognition according to an embodiment of the present invention includes the following steps:
[0030] The location information and time information sent by the wearable devices worn by the personnel in the case handling area are obtained and recorded as the first trajectory information.
[0031] After the face recognition device acquires and sends the face information of the person, the time information sent by the face recognition device and the identification information of the face recognition device are acquired.
[0032] The location information of the face recognition device is obtained according to the identification information and recorded as second trajectory information.
[0033] The second trajectory information is added to the first trajectory information according to a time sequence to obtain third trajectory information.
[0034] The trajectory information of the person is obtained according to the third trajectory information.
[0035] It should be noted that there is no time limit for the order of obtaining the first trajectory information and the second trajectory information. In actual operation, the location information and time information of the wearable device worn by the person may be obtained first, and then the time information sent by the face recognition device and the identification information of the face recognition device may be obtained, and vice versa.
[0036] Therefore, according to the case handling area management method based on ultra-wideband and face recognition of an embodiment of the present invention, by combining the ultra-wideband technology of wearable devices with the face recognition technology of face recognition devices, the two complement each other in function, providing the case handling area with more intelligent process guidance and more accurate trajectory recording services.
[0037] According to one embodiment of the present invention, the personnel wears the wearable device before entering the case handling area.
[0038] In some specific embodiments of the present invention, the personnel perform facial collection and registration before entering the case handling area. Optionally, there are multiple function rooms in the case handling area, and the entrance of each function room is provided with the face recognition device, and the personnel enter the function room after the face recognition device recognizes the person. Furthermore, when the personnel leaves the function room, they leave the function room after being recognized by the face recognition device. Specifically, when the personnel leaves the function room, they leave the function room after the face device inputs a leave instruction.
[0039] In the case handling area management method based on ultra-wideband and face recognition of the present invention, the wearable device may be a bracelet, and the face recognition device may be a tablet computer.
[0040] In other words, according to the case handling area management method based on ultra-wideband and face recognition in the embodiment of the present invention, before entering the case handling area, personnel can first perform face collection and registration on the entry tablet or the case handling center terminal, and then bind the wristband on the case handling center terminal, and enter the case handling area after the binding is completed. There is a corresponding tablet terminal at the door of each functional room in the case handling area, and personnel need to perform face verification when entering the functional room. The wristband is used as the main track recording method, and the tablet face verification is used as a means of track correction.
[0041] For function rooms equipped with tablets, when a person enters the function room, he needs to scan his face on the tablet first. When recording the trajectory, the judgment of whether the face is scanned will be added, so as to more accurately record the time node when the person enters the function room and prevent the wrong bracelet area switching when the person passes by the area boundary. In addition, when a person leaves the function room, he needs to click to leave on the tablet at the door, and the precise time node when the person leaves the function room can also be obtained. When recording the bracelet trajectory, it will add whether to click to leave on the function room tablet, so as to achieve the effect of trajectory correction. The case handling process of personnel in the case handling area mainly relies on tablets for authentication control and process guidance. The specific process is as follows Figure 1 shown.
[0042] like Figure 2 As shown, the case handling area management system 100 based on ultra-wideband and face recognition according to an embodiment of the present invention includes: a wearable device 10, a face recognition device 20, a first marking module 30, a second marking module 40, a third marking module 50 and a fourth marking module 60.
[0043] Specifically, the wearable device 10 can send the location information and time information of the case handling area, the face recognition device 20 can obtain and send the face information of the personnel, the first marking module 30 can obtain the location information and time information sent by the wearable device 10, and record it as the first trajectory information, the second marking module 40 can obtain the time information sent by the face recognition device 20 and the identification information of the face recognition device 20, and obtain the location information of the face recognition device 20 according to the identification information, recorded as the second trajectory information, the third marking module 50 adds the second trajectory information to the first trajectory information according to the time sequence to obtain the third trajectory information, and the fourth marking module 60 can obtain the trajectory information of the personnel according to the third trajectory information.
[0044] According to one embodiment of the present invention, a plurality of functional rooms are provided in the case handling area, and a face recognition device 20 is provided at the entrance of each functional room. A person enters the functional room after being recognized by the face recognition device 20.
[0045] Optionally, the wearable device 10 is a bracelet, and the face recognition device 20 is a tablet computer.
