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...

The invention relates to a method and a system for intelligently tracking video on the basis of track cameras. The method includes selecting and tracking initialized targets O from a plurality of targets; correcting positions of the targets O to obtain new tracked targets O<i+1>; computing matching degrees of the targets O<i+1> and the targets O, deleting the targets O<i+1> if the matching degrees are smaller than preset values, and reselecting initialized targets; shifting the cameras to specified positions if the matching degrees are higher than the preset values and the targets O<i+1> leave set regions, and acquiring new positions W2 of the targets O<i+1>; correcting positions of the targets O<i+1> again if the targets O<i+1> are located in the set regions. The method and the system have the advantages that the method and the system are wide in monitoring tracking range; the cameras can move under the control, so that the targets can be comprehensively monitored, and the problem of constraints due to the fact that existing cameras only can be fixed at certain places to carry out camera monitoring is solved by the aid of the system and the method.
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...
