Description

technical field [0001] The invention relates to the field of security technology, in particular to a multi-target continuous tracking system and method based on pan-tilt control technology. Background technique [0002] At present, the continuous tracking of targets based on multiple cameras mostly uses the feature data of the monitored background and targets to be transmitted to the background server, and the background server uses the SIFT (Scale Invariant Feature Transform) feature matching of the background image to detect the repeated areas between the cameras. According to the key points, the corresponding relationship between the overlapping areas between the cameras is established, and then the tracked target is cut out to calculate the SIFT feature value, which is matched with the target of the adjacent camera, so as to complete the continuous tracking of the target. [0003] The tracking target in the prior art is subject to factors such as illumination, weather, o...

AI Technical Summary

Problems solved by technology

[0003] The tracking target in the existing technology is subject to factors such as illumination, weather, occlusion, and similarity in clothing, which lead to uncertainty in target matching. In addition, it is impossible to judge whether it is a valid target from the actual calculated trajectory and velocity.

When the target is mixed into the background of the same group, for example, when the target is dressed similarly to other targets in the background, it is easy to follow or track wrongly

With the method of multi-camera splicing, the target cannot be zoomed in, and more pixel features cannot be obtained.

The back-end server load is directly affected by the number of front-end cameras, so it cannot be easily expanded and extended

[0004] Now high-point monitoring, the linkage between monitors is still in its infancy. How to transmit the coordinate information of the monitored target between cameras has become a major difficulty. First, the monitored target will not actively report its own GPS information. Secondly, the monitored target The trajectory of the target is very random. At present, the blind spot of the ordinary bolt is very large, and it is impossible to achieve large-scale monitoring coverage. Therefore, the multi-camera tracking system (hereinafter referred to as the tracking system) controlled by the pan-tilt is used. Due to the need to track the target For continuous tracking, it is very necessary to transmit the GPS information of the tracked target between multiple tracking systems. When the tracked target leaves the tracking range of the tracking system, the tracking system will transmit the GPS information of the tracked target to the surrounding tracking systems. , to complete the tracked relay
