Example Embodiment

[0055] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0056] The basic idea of ​​the present invention is: determine the moving direction of the monitoring target according to the image position information, and send a control signal to the mechanical pan / tilt installed with the camera, so that the mechanical pan / tilt drives the camera to move with the position change of the monitoring target, that is, the camera is realized. Automatic tracking.

[0057] At the same time, since the position change of the monitoring target is not limited to movement in a plane perpendicular to the shooting direction of the camera, it may also move parallel to the shooting direction of the camera, which requires the camera to be focused. In this way, while realizing the automatic tracking of the camera, a control sig...

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...
