Box camera and dome camera linkage coordinate positioning method

Abstract

The invention discloses a box camera and dome camera linkage coordinate positioning method. The box camera and dome camera linkage coordinate positioning method comprises the steps that: firstly, an IP address of a dome camera is set for a box camera, the box camera is connected with and logs into the dome camera actively, and lens parameters of the box camera and related parameters of a CMOS image sensor need to be pushed to the dome camera after the box camera is connected with the dome camera; and the dome camera is always in a command waiting state, if a box camera and dome camera coordinate system is calibrated, the dome camera converts coordinates of a frame-selected region of interest of a frame of the box camera into motor coordinates of a dome camera holder after the dome camera receives a box camera and dome camera positioning command, then the dome camera executes a positioning action and drives a horizontal-vertical motor to reach a corresponding position, and finally, thedome camera adjusts lens focal length in a self-adaptive manner according to the area size of the region of interest, so that the region of interest covers a whole screen. According to the box cameraand dome camera linkage coordinate positioning method, even if only one point is allowed to be calibrated in a video frame, the coordinate system calibration of a box camera and dome camera positioning system can be completed, and the box camera and dome camera positioning can be more precise through calibrating a plurality of points.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to a gun-ball linkage coordinate positioning method. Background technique [0002] The bolt camera has a large field of view, but it cannot pay attention to the image details at a distance; the ball camera has a wide monitoring range, and more details can be seen through the lens zoom. For the gun ball positioning system, the user can see two preview screens of the bolt camera and the dome camera. The user can frame any area of ​​interest on the bolt camera screen, and the dome camera will automatically close-up the area. The gun-ball linkage system combines the advantages of both the bolt camera and the ball camera, which can not only see a wider field of view, but also capture the details in the distance. Usually, when deploying the gun ball positioning system, it is necessary to calibrate more than three points to associate the coordinate system of the gun and the bal...

AI Technical Summary

Problems solved by technology

Usually, when deploying the gun ball positioning system, it is necessary to calibrate more than three points to associate the coordinate system of the gun and the ball camera to achieve linkage positioning. However, in some application scenarios, there may not be enough prominent scenes in the video screen to calibrate the gun ball. Linkage coordinate system, it will be difficult to manually calibrate the gun ball positioning system at this time
