Problems solved by technology

[0004] In the above solution, if the calibration is inaccurate, or if the position of the trigger or the ball camera changes after calibration, the mapping relationship will be inaccurate, and the PTZ information determined by the trigger according to the mapping relationship will also be inaccurate. In this way, the surveillance target may not exist in the image collected by the adjusted speed dome camera
It can be seen that the monitoring effect of the above scheme is poor

Embodiment approach

[0109] As an implementation manner, the device may further include: a first control module and / or a second control module (not shown in the figure), wherein,

[0110] A first control module, configured to control the second type of monitoring equipment to collect detailed images of the monitoring target;

[0111] A second control module, controlling the second type of monitoring equipment to track the monitoring target.

[0112] As an implementation manner, the second type of monitoring equipment is a movable monitoring equipment; the second control module can specifically be used for:

[0113] The trajectory of the monitoring target is predicted, and the movement of the second type of monitoring equipment is controlled according to the trajectory, so as to track the monitoring target.

[0114] As an implementation, the device may also include:

[0115] The third control module (not shown in the figure) is configured to control the second type of monitoring device to move to...

Abstract

The embodiment of the invention provides a target monitoring method, device, apparatus and system, and the method comprises the steps: obtaining the attribute of a monitoring target in an acquired image of a first type of monitoring equipment instead of calibrating the two types of monitoring equipment, and carrying out the matching and determination of the monitoring target in an acquired image of a second type of monitoring equipment according to the attribute of the monitoring target; Therefore, the determination of the monitoring target is not influenced due to inaccurate calibration or change of the position of the monitoring equipment, so that the monitoring effect is improved.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a target monitoring method, device, equipment and system. Background technique [0002] Among the existing monitoring equipment, some monitoring equipment has a wide viewing angle, but the image definition is poor, such as a bolt camera; some monitoring equipment has a good image definition, but a small viewing angle, such as a dome camera. In some schemes, the monitoring of the target is realized through the linkage of these two monitoring devices, which can take into account the viewing angle and the clarity of the picture. [0003] Taking the linkage of bolt and dome as an example, the scheme generally includes: calibrate the bolt and dome, and obtain the mapping relationship between the image captured by the bolt and the image collected by the dome in each field of view through calibration; , the bolt collects a large-view image, detects the monitoring targe...
