Large-scene multi-target cooperative tracking method, intelligent monitoring system, and transportation system

Abstract

The invention belongs to the technical field of the device for controlling camera, and discloses a large-scene multi-target cooperative tracking method, an intelligent monitoring system, and a transportation system. A target can be accurately divided by adopting master-slave cooperation in target staggering, the tracking robustness is improved, wherein a master machine is a fixed wide-angle camera, namely a gun camera; the slave is a high-resolution variable-focus ballhead camera, namely the ballhead camera. The invention comrpises a gun camera and ballhead camera relation module, a target detection module, a priority judgment module, a control module, a target updating module, and a tracking module. The priority classification is performed in the multi-target relation in the gun camera picture, the action of the ballhead camera is determined according to the target relation, the ballhead camera utilization rate is improved, and the resource is saved; the ballhead camera acquires a high-definition camera at a target staggering region in the gun camera picture, the ballhead camera performs target detection on the high-definition image, and the detection accuracy rate of the target is improved. The ballhead camera picture detection information is mapped back to the gun camera picture through a relation matrix between the gun camera and the ballhead camera, and then the target staggering region is re-divided to realize the cooperative tracking.

Problems solved by technology

This method cannot separate the target independently in the target staggered area, and only uses the trajectory prediction method to predict and track the position of the target, which is difficult to achieve robust tracking

[0003] In summary, the problems in the prior art are: The existing small target anti-occlusion tracking methods in large scenes only use the trajectory prediction method to predict and track the position of the target when the targets are staggered, but when the targets are staggered, the avoidance between targets is easy to appear The change of motion speed and direction after staggering, while the trajectory prediction method uses the motion state data of the target before staggering, it is very easy to have a difference between the predicted position and the actual position of the target, especially when three or more targets are staggered. There is a large difference in position. After the target interleaving is over, tracking errors or tracking loss are prone to occur

[0004] The difficulty and significance of solving the above technical problems: In a large scene, the target is small, and the feature difference between the targets is not obvious. When multiple targets are interlaced, it is difficult to segment a single target. At the same time, the motion state of the target is prone to large changes. It is difficult to accurately predict only relying on the motion information of the target before interlacing. The position after the target stagger ends, which is easy to cause tracking errors or loss
