Automatically tracking and controlling method and control device in the video monitoring

Abstract

The invention discloses an auto tracking control method and device in video monitoring. According to the obtained image position information, the invention judges the moving direction of the monitored object and controls mechanical platform to drive camera to track the moving monitored object and makes the monitored object all along able to be in the center of a monitoring picture, improving video monitoring reliability. At the same time of implementing automatic tracking, it can judge variation trend of image definition according to the image definition information and sends control signal to a camera focuser by this, so as to make the monitoring picture keep a higher definition all along, implementing automatic focusing and further improving video monitoring reliability.

Description

technical field [0001] The invention relates to monitoring technology, in particular to an automatic tracking control method and automatic tracking control device in video monitoring. Background technique [0002] With the continuous development of multimedia technology, video surveillance has been more and more widely used in security operations, public security and other fields. [0003] In the process of video surveillance, the surveillance target is usually in motion. In this case, the image sensor in the video surveillance system needs to be driven by the mechanical head to track the monitoring target in a moving state, so that the monitoring target is always within the shooting range of the camera. At this time, it is also necessary to adjust the focal length of the camera as the position of the monitoring target changes, so as to ensure that the monitoring picture captured by the camera has high definition. [0004] FIG. 1 is a schematic structural diagram of an exi...

Problems solved by technology

[0007] However, the above-mentioned video surveillance system needs human control to realize the tracking of the monitoring target and the adjustment of the focal length.

Moreover, if the monitoring personnel do not watch the monitoring picture in front of the monitoring station, then when the monitoring target leaves the monitoring range, the video surveillance system cannot track the monitoring target and adjust the shooting focal length, so that the real-time monitoring of the monitoring target cannot be realized.

[0008] It can be seen that the existing video surveillance system cannot effectively guarantee the real-time monitoring of the monitoring target, so its reliability is not high
