Problems solved by technology

However, due to the influence of lens distortion, the imaging of the cross laser may be curved. In addition, due to the influence of laser scattering, the width of the cross laser imaging will increase. All of the above situations will affect the accuracy of the straight line detection results. This leads to the problem of inaccurate positioning

Abstract

This application relates to a cross laser detection and positioning method, device, storage medium and computer equipment. By performing skeleton extraction processing on an image containing a cross laser, the imaging width of the cross laser can be effectively reduced, and the influence of laser scattering can be reduced or even avoided. , so as to facilitate the straight line fitting process and improve the accuracy of the straight line fitting result; after the straight line fitting, further curve fitting is performed according to the straight line fitting result, which can reduce or even avoid the influence of lens distortion. Through the above processing process, Therefore, the accuracy of cross laser positioning can be improved.

Description

technical field [0001] The present application relates to the technical field of machine vision, in particular to a cross laser detection and positioning method, device, storage medium and computer equipment. Background technique [0002] Machine vision (machine vision) technology refers to the technology that uses machines to replace human eyes for measurement and judgment. This technology first obtains the image of the target, and then performs image processing according to the pixel distribution, brightness, color and other information of the image to obtain the target image. Shape, orientation and other information are convenient for subsequent processing. [0003] In most of the existing automation equipment, the laser positioning process is mostly completed through machine vision technology, for example, the detection and positioning of the cross laser is performed through machine vision technology. Specifically, in the prior art, the line detection of the cross laser...
