Panorama splicing linkage method and device based on moving target detecting

Abstract

The invention provides a panorama splicing linkage method and device based on moving target detecting. A large-view panorama image is obtained by panorama splicing, then view is adjusted, the position mapping relation of a ball machine and a panorama splicing video camera is established, then moving target detecting is carried out on an area of interest in the panorama image, after a moving target is detected, the corresponding ball machine is automatically triggered to track the target of the area of interest according to the mapping relation to achieve linkage, accordingly, the problem that the moving target (a human face, a license plate and the like) in the panorama image cannot be seen clearly under the situation of long distance is avoided, workload of monitoring personnel is reduced, a complete, large-view, and high-resolution continuous image is provided for an operator, the observing angle is similar to the view angle of a human eye, and switching back and forth between images during monitoring is avoided.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a panorama splicing linkage method and device based on moving object detection. Background technique [0002] Today, with the rapid development of the monitoring system, the scale of the system is getting bigger and bigger, and there are more and more monitoring points. The staff have no time to take care of more and more monitoring images. With the continuous expansion of the monitoring range, it is necessary to monitor the entire bridge. , Airports, a long section of road or high-rise buildings are monitored, and the field of view of most cameras cannot reach such a large monitoring range. Therefore, the requirements for video surveillance with a large field of view are gradually increasing, and a high-end demand has gradually formed. As a solution, panoramic video stitching has also received more and more attention. The accompanying video surveillance system ...

Problems solved by technology

[0003] So far, there are two types of common monitoring equipment. The first is the trigger, which is aimed at a certain scene for monitoring. The disadvantage is that when there are many monitoring scenes, it is necessary to switch back and forth between each scene. When there are many channels and frequent switching, the monitoring personnel will get tired easily, and people's attention can only be concentrated on part of the screen; The field of view of the camera is limited, and only one scene can be monitored at the same time, so some important information will still be missed

[0004] In the target tracking process, if you rely solely on the dome camera, the tracking effect is affected by many factors, whether it is through manual ball control or automatic tracking of the target, and it is prone to tracking failure or target switching. Near the target, it is easy to miss other important information

If relying on the gun, the target is likely to appear in multiple screens, and the switching between screens will affect the capture of video information by the surveillance personnel, and the installation direction of the gun is fixed, the monitoring scene will not change with the target, and it is easy to lose the tracking target

And in video surveillance, often due to the long distance of the target, the accuracy of detection and recognition of the target (face, license plate, etc.) is low
