Embodiment Construction
[0035] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.
[0036] The overall design idea of this technical solution is to use the fixedness of multiple "identity feature" information (such as face features, clothing features, mobile phone MAC, etc.) (such as crossroads, subway exits, etc.) personnel may carry out multi-point continuous deployment and control in the direction of travel.
[0037] Such as figure 1 As shown, the associated monitoring point is the associated camera on the possible historical trajectory of the target. Assuming that the No. 1 camera is a subway exit camera, and the target’s traveling direction is judged to be exiting from the subway exit, there is no associated camera on the historical trajectory; when the No. 2 camera detects To the target and the direction o...

The invention discloses an interested target monitoring method and device, and the method comprises the steps of comparing an identity feature detected visually with collected wireless equipment information with an interested target list, binding a snapshot video frame, a target identity feature, and a wireless equipment information comparison result into an object package, and sending the objectpackage to a back-end server; using the back-end server to receive the object packet reported by the monitoring camera; and storing the object packet in a storage directory corresponding to the monitoring camera, and performing repeated wireless device information searching in the object packet stored in the associated monitoring point according to the information contained in the object packet soas to determine an interested target and wireless device information corresponding to the interested target and generate corresponding alarm information. According to the present invention, the confidence coefficient of the interested target and the wireless equipment information thereof is determined based on multiple identity characteristics, the interested target detection and the wireless equipment information searching can be carried out as long as the facial characteristics are detected once, the influence of people flow density is small, and the higher accuracy and stability are achieved.
Description
technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a monitoring method and device for an interested target. Background technique [0002] With the development of video surveillance technology, tracking and monitoring objects of interest has gradually become a standard function in the security field. In the actual application scene, the camera is generally configured to detect and capture the people in the monitoring scene, and then compare and analyze the preset target through the back-end server (or directly implement it on the camera). Once the target of interest is captured, it can be triggered. A series of linkage programs such as follow-up continuous tracking. [0003] However, the actual monitoring scene is more complex, such as building occlusion, dense crowds, etc., which brings certain difficulties to the discovery of interesting targets and continuous tracking through video analysis. Purely through...
