Embodiment Construction
[0058] 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.
[0059] First, a brief introduction is given to the nouns involved in the embodiments of the present application.
[0060] Radar: A device that uses electromagnetic waves to detect targets and has the characteristic of working around the clock. By emitting electromagnetic waves to irradiate the target and receive its echo, the distance from the target to the electromagnetic wave emission point, distance change rate (radial velocity), azimuth, height and other information can be obtained.
[0061] Speed dome camera: It has a mechanical structure such as a pan / tilt, and is a large-scale surveillance camera that can change PTZ, and can take into account the panoramic information and detailed information of the surveillance scene. ...

The invention discloses a linkage monitoring device and method and a storage medium, and belongs to the technical field of monitoring. The device comprises radar, a dome camera, a height measurement module and a central processing module, and the radar and the dome camera are relatively and fixedly connected; the height measurement module is fixedly connected with the dome camera and is used for detecting a first height, and the first height is the height from the dome camera to the horizontal ground; the central processing module is connected with the radar, the dome camera and the height measurement module and is used for determining a mapping relation between radar coordinates and dome camera coordinates based on the first height, the second height and the view field included angle so as to perform joint calibration on the radar and the dome camera; the second height is the relative height of the radar and the dome camera in the vertical direction, and the view field included angle is the included angle between the zero-degree view field angle of the radar and the zero-degree view field angle of the dome camera. According to the method, joint calibration by manually collecting data for multiple times is avoided, and the calibration efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of monitoring, and in particular to a device, method and storage medium for linkage monitoring. Background technique [0002] Since the radar has the characteristics of working all day and all day, and the dome camera can take into account the panoramic information and detailed information of the monitoring scene, the joint monitoring of the radar and the dome camera can make up for the monitoring performance of the dome camera in low light and bad weather. Reduce radar false detection rate. [0003] In the joint monitoring process of radar and dome camera, in order to realize the detection and fusion of the same target by radar and dome camera, it is necessary to determine the mapping relationship between radar and dome camera for joint calibration, so as to achieve the same target in radar and dome camera Mutual conversion under the corresponding coordinate system. At present, professionals are...
