Problems solved by technology

However, this kind of intelligent video surveillance is only for recording and tracking the targets in a fixed camera range, and the range of monitoring and tracking is small. For places with a wide monitoring range and few people, this kind of intelligent monitoring system will not be able to monitor comprehensively. Monitor dead angles, resulting in safety hazards and other issues

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] See figure 1 , a kind of intelligent video tracking method based on track camera, comprises the following steps:

[0037] Step S1, collect the video image in the field of view of the camera, detect several targets in the video image, select and track the initialized target O among several targets i .

[0038] Step S2, to target O i Perform position correction to get a new tracked target O i+1 . Select and target O in the video image i The feature most similar to the target marked as a new tracked target O i+1 , so as to achieve position correction, where the feature can be defined in terms of velocity and size.

[0039] Step S3, calculating the target O in step S2 i+1 with target O i The matching degree, if the matching degree is less than the preset value, delete the target O i+1And return to step S1, if the matching degree is...

Abstract

The invention relates to an intelligent video tracking method and system based on a track camera. The method includes: selecting and tracking the initialized target Oi among several targets, correcting the position of the target Oi to obtain a new tracked target Oi+1, calculating the matching degree between the target Oi+1 and the target Oi, if the matching degree is less than If the preset value is set, delete the target Oi+1 and re-select the initialized target. If the matching degree is greater than the preset value, if the target Oi+1 leaves the set area, then move the camera to the specified position to obtain the target Oi+1 If the new position W2 of the target Oi+1 is within the set area, the position correction is performed again. The scope of monitoring and tracking of the present invention is wide, that is, comprehensive monitoring can be realized by controlling the movement of the camera, and the limitation problem that the camera can only be fixed in a certain place for camera monitoring is solved.

Description

technical field [0001] The invention relates to safety monitoring technology, in particular to an intelligent tracking method and system. Background technique [0002] The video surveillance system can reflect the pictures of the monitored and controlled objects timely, graphically and truly in places where people cannot directly observe, so it has become the most effective observation tool for the majority of users to monitor in modern management. [0003] With the rapid growth of the national economy, the rapid progress of society and the continuous enhancement of national strength, the demand for safety precautions and on-site recording and alarm systems in the fields of banking, electric power, transportation, security inspection and military facilities is increasing day by day, and the requirements are getting higher and higher. Video Monitoring has been widely used in all aspects of production and life. Although monitoring systems have been widely used in public place...
