Linkage control method and device for panoramic mosaic camera and dome camera

Abstract

The invention provides a linkage control method and device for a panoramic mosaic camera and a dome camera. The linkage control method and device for the panoramic mosaic camera and the dome camera have the advantages that firstly, a large-view panoramic picture is obtained in a panoramic mosaic mode, then the view is adjusted, the position mapping relation of the dome camera and the panoramic mosaic camera is built, linkage is achieved on the area using equipment to obtain objects in the panoramic picture according to the mapping relation, therefore, the situation that moving objects (human faces, license plates and the like) in the panoramic picture cannot be seen clearly in the long distance is avoided, workloads of monitor personnel are reduced, interested areas in the panoramic picture can be selected manually to achieve the linkage of the dome camera, a complete, large-view and high-resolution continuous picture is provided for an operator and is closer to the view angle observed by human eyes, and the situation that all pictures are switched over back and forth in the monitoring process is avoided.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for linkage control of a panoramic splicing camera and a dome camera. 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 surveillan...

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
