Abstract

The invention discloses a gun camera-dome camera positioning method and device, and aims at solving the problem that the gun camera-dome camera linkage systems in the prior art are relatively low in positioning precision and relatively large in positioning deviation. The method comprises the following steps of selecting N reference points in a reference image acquired by a gun camera; and determining calibration parameters according to positions, in the reference image, of the N reference points and a corner corresponding to each reference point, so as to determine a target corner corresponding to a target point in the image acquired by the gun camera. According to the method, the positioning of the gun camera the dome camera can be completed through calibrating at least three reference points, the positioning precision is high and the positioning correctness is high.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a gun ball positioning method and device. Background technique [0002] With the development of science and technology, intelligent tracking technology is applied to more and more occasions, such as large exhibition halls, conference halls and dangerous road sections. Combined with intelligent tracking technology to monitor the scene, it can save security personnel and avoid security loopholes caused by the mobility of security personnel. [0003] The bolt camera can monitor a wider range of scenes, and the dome camera can zoom in on the monitored object, allowing users to observe the details of the monitored object. However, the bolt camera alone cannot monitor the detailed area, and the dome camera alone cannot monitor the entire scene. Therefore, the bolt camera and the dome camera need to be monitored in conjunction to achieve the purpose of monitoring the detailed area in a ...
