Long-distance laser light path calibration system and method based on machine vision

Abstract

The invention discloses a remote laser light path calibration system and method based on machine vision, and the system comprises a laser, a target surface, a camera, a steering engine, and a first adjustment control module which is used for obtaining the position of a light spot and the error between the light spot and the center of the target surface; the second adjusting control module is used for adjusting the position of the laser through an error control steering engine; a laser spot is generated through a laser and is presented on a target surface, a camera is arranged on the side, away from the laser, of the target surface, the camera collects a spot image on the target surface, and the laser is fixed to a steering engine. Thus, the machine vision technology is adopted, error data are calculated through an algorithm, then the steering engine is controlled through the single chip microcomputer, the position of the laser device can be automatically adjusted, the laser device irradiates the target position, and the laser device has the advantages of being wider in application range, lower in cost, higher in automation degree and higher in precision.

Description

technical field [0001] The invention relates to the technical field of laser calibration, in particular to a long-distance laser optical path calibration system and method based on machine vision. Background technique [0002] Machine vision is a rapidly developing branch of artificial intelligence. Simply put, machine vision is to use machines instead of human eyes to make measurements and judgments. The machine vision system converts the captured target into an image signal through machine vision products, namely image capture device, CMOS camera and CCD camera, and transmits it to a dedicated image processing system to obtain the morphological information of the captured target, according to the pixel distribution and brightness. , color and other information are converted into digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the result...

AI Technical Summary

Problems solved by technology

However, in many cases, when the position of the laser is far away from the target point, it is difficult to irradiate the laser at the target position. Therefore, it is difficult to realize the automatic adjustment of the position of the laser at a relatively long distance in the prior art.
