Laser machine and camera linking control method, device and system

Abstract

The invention provides a laser machine and camera linking control method, device and system, which are applied in a shooting device, comprising the laser machine and the camera. The camera moves alongthe moving of a target object. The laser machine and camera linking control method comprises the steps that the parameter information of lens of the camera is obtained, wherein the parameter information of lens of the camera is corresponding to the shooting area of the camera; the parameter of a target light-filling area of the laser machine can be determined based on the lens parameter information of the camera; the emergent light parameter of the laser machine can be adjusted based on the target light-filling area of the laser machine, so that the target object shot by the camera can be placed in the target light-filling area. The invention is advantageous in that the definition of the object shot by the camera can be increased.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method, device and system for linkage control of a laser and a camera. Background technique [0002] Video surveillance is an important part of the security system, and the most important video surveillance equipment is a surveillance camera. Surveillance cameras are mainly divided into gun-type equipment, hemispherical equipment and dome-type equipment in terms of appearance, and there are also distinctions between analog monitoring and network monitoring. They are widely used in many security fields such as banking, transportation, and safe cities. Because the dome camera equipment can use the stepper motor to quickly and accurately position and rotate the camera according to the actual motion of the object being photographed, it can track the photographed object very well, and it plays a very important role in the fields of urban public security and traffic monitori...

AI Technical Summary

Problems solved by technology

[0004] At present, the mechanical structure of the laser structure adjustment module on the market is relatively solid, which leads to the fixed light supplementary area formed by the laser emitted by the laser module.

When the object being photographed moves, the camera will follow the rotation of the object. Since the laser fill light area is fixed, when the object moves to the edge position of the fill light area or moves out of the fill light area, because the edge position of the fill light area and The clarity of the fill light in areas other than the fill light area is low, and the fill light area of ​​the existing laser fill light is difficult to adjust, resulting in low definition of the captured object and poor fill light effect
