Problems solved by technology

[0004] 1) There is no modular division of the public security criminal investigation video system;
[0005] 2) The storage module of the system is single, and the real-time video of public security criminal investigation and the historical video of public security criminal investigation cannot be stored and analyzed separately;
[0006] 3) It is not possible to divide the public security criminal investigation video into blocks, and the retrieval speed of the public security criminal investigation video is relatively slow;
[0007] 4) At present, a large number of surveillance videos of public security criminal investigations are fixed and cannot be moved

Embodiment 1

[0037] Such as figure 1 As shown, the present invention provides a mobile video analysis system for public security criminal investigation, including a video analysis cloud platform and a mobile device;

[0038] The mobile device includes a video acquisition unit, a video real-time analysis unit, a local storage unit, a buffer and an identification module;

[0039] Described video collection unit is used for collecting and detecting the video of relevant human face or license plate, and this video is stored in buffer zone, after the specified time uploads video to video analysis cloud platform, deletes this video again;

[0040] The buffer is used to cache and store the video of the relevant face or license plate collected and detected by the video acquisition unit;

[0041] The recognition module is used to load two algorithms of face recognition and license plate recognition;

[0042] The local storage unit is used to store face data and license plate data entered in advan...

Embodiment 2

[0053] Embodiment 2 On the basis of Embodiment 1, the storage unit further includes a data mining module for mining valuable information. The mobile device also includes a load balancing module, the load balancing module is arranged between the video real-time analysis unit and the local storage unit, and is used to improve the performance of the public security criminal investigation client.

[0054] The identification module includes a real-time identification module and an offline identification module;

[0055] When the video real-time analysis unit adopts the real-time recognition module to analyze and recognize the video of the face or the license plate, the video analysis is performed in real time during the receiving process of the coded string, without waiting until all the video buffers are docked. During the video analysis process, the All video results participating in the recognition analysis will be cached in the buffer in real time, and after traversing all the ...

Abstract

The invention discloses a mobile video analysis system for public security criminal investigation. The system comprises a video analysis cloud platform and a mobile device, wherein the mobile device comprises a video collection unit, a video real-time analysis unit, a local storage unit, a buffer area and an identification module, wherein the video real-time analysis unit acquires video of associated faces or license plates collected by the video collection unit, runs algorithm of the identification module, analyzes the faces or the license plates, compares face data or license plate data of the local storage unit, and gives an alarm prompt if abnormity occurs; and the video analysis cloud platform comprises a storage unit, a metadata server and a history analysis unit, wherein the historyanalysis unit receives an analysis task issued by the mobile device, firstly, sending information to the metadata server, and finding video content to be analyzed, then going directly to the storageunit to get the video content and analyzing, and finally returning the analyzed data the mobile device. According to the mobile video analysis system for public security criminal investigation, the flexibility of the video collection and the retrieval speed of the video are improved.

Description

technical field [0001] The invention relates to the technical field of public security criminal investigation, in particular to a mobile video analysis system for public security criminal investigation. Background technique [0002] With the continuous expansion of the scale and application fields of the public security criminal investigation video surveillance system, a large amount of video data has brought challenges to the response speed of real-time monitoring and the effectiveness of data utilization. The current public security criminal investigation video surveillance system has many disadvantages in actual operation. : A large number of cameras and insufficient display screens result in the need for split-screen or wheel-screen monitoring, but the wheel-screen is likely to cause dead ends in monitoring. Too many display screens require a large number of monitoring personnel, and it is difficult for monitoring personnel to pay attention to every video and make a quic...
