Problems solved by technology
[0004] However, before the gun-ball linkage system is used to track and shoot, the processing device needs to obtain the PTZ parameters corresponding to each pixel in the video stream of the bolt through pre-calibration. The pre-calibration process is usually complicated, resulting in The process of using the system is more complicated

Embodiment Construction
[0087] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0088] In recent years, the application of intelligent monitoring system has become more and more extensive. The intelligent monitoring system can capture the detailed information of the target object while monitoring a large area. When the target object is constantly moving, the intelligent monitoring system can track and shoot the target object, thereby obtaining the moving track of the target object and improving the monitoring effect of the target object.
[0089] figure 1 For a schematic structural diagram of a monitoring system provided in the embodiment of this application, see figure 1, the monitoring system 10 includes a plurality of camera devices (such as figure 1 the second camera device 1011 and the first camera d...

The invention discloses a tracking shooting method and device and a monitoring system, and belongs to the field of video processing. The tracking shooting method comprises the steps of: obtaining target parameters corresponding to a first camera device, enabling the target parameters to indicate field-of-view parameters when the first camera device shoots a target area, wherein the target area isan area which can be shot by both a second camera device and the first camera device; obtaining a first video stream shot by a second camera device, wherein the first video stream records the state ofthe target area; determining a target object according to the first video stream, wherein the target object is located in the target area; and sending a first adjustment instruction to the first camera device, wherein the first adjustment instruction carries the target parameter, and the first adjustment instruction instructs the first camera device to adjust the shot field of view based on the target parameter, so that the adjusted field of view comprises the target area. According to the invention, a complex calibration process is not needed, and the process of monitoring the target objectby using the monitoring system can be simplified.
Description
technical field [0001] The present application relates to the field of video processing, in particular to a tracking and shooting method and device, and a monitoring system. Background technique [0002] In the video surveillance scene, the gun-ball linkage system is usually used for tracking and shooting. The gun-ball linkage system includes a gun-type camera device (abbreviated as gun camera), a ball-type camera device (abbreviated as ball camera) and a processing device. The bolt is used to collect a large-scale video stream, the dome is used to collect a small-scale and high-definition video stream, and the processing device is used to process the video streams of the bolt and the dome. The gun ball linkage system is used to track and shoot the target object moving in a wide range, which can not only monitor the target object in a large range, but also track and shoot the details of the target object, so as to achieve better monitoring effect. [0003] At present, befo...
