Monitoring and tracking method for continuous movement of specific target and suspected target

Abstract

The invention discloses a monitoring and tracking method for continuous movement of a specific target and a suspected target, and belongs to the technical field of urban video monitoring safety. The method comprises the following steps: after missing of specific targets such as articles and personnel occurs at a certain monitoring camera, performing specific target identification on a monitoring video in a specific range by adopting a machine automatic identification article model; determining a suspected target according to the contact area with the specific target in the monitoring picture after the specific target is recognized; tracking accompanying movement of the specific target and the suspected target in a specific range to obtain accompanying movement tracks of the specific targetand the suspected target in the specific range; and predicting the next possible monitoring area according to the accompanying movement track of the specific target and the suspected target. Police case handling personnel can adopt an advanced squatting monitoring mode in the next possible occurrence area of the specific target and the suspected target, so the case detection time is shortened, the case handling efficiency is greatly improved, and the waste of human resources is reduced.

Description

technical field [0001] The invention relates to the technical field of urban video surveillance security, in particular to a monitoring and tracking method for continuous movement of specific targets and suspected targets. Background technique [0002] With the advancement and development of science and technology, in the field of computer vision, applications such as face recognition, unmanned driving, and unattended video surveillance have emerged. With the increase of high-tech crimes, video surveillance at the scene of the crime, tracking and monitoring of specific targets and suspected targets are of great significance for locking suspects and reducing the time to solve the case. However, due to the limitations of storage devices and video shooting technology, there have been problems such as video accumulation, manual screening is difficult and time-consuming. If the detection, positioning, tracking and identification of targets in surveillance scenes can be realized ...

AI Technical Summary

Problems solved by technology

However, with the continuation of the time after the case occurred and the expansion of the moving range of the suspected target, human inspection of the surveillance video can no longer meet the requirements of handling the case.

At present, the automatic tracking and detection of specific targets such as objects and personnel are only tracked and monitored for a single specific target.

Tracking and monitoring of a single specific target has little effect on case detection due to problems such as little tracking information, incomplete tracking process, and inconspicuous tracking effect
