Embodiment Construction

[0100] The research of the present invention is the detection of the edge parameters of the laser scribe line of the solar battery panel. During the production process of solar panels, several lines must be engraved on the solar panel glass, and laser engraving is generally used. Due to the detection of the laser scribed line after the coating, the reflection of the glass surface and the abrasion of the coating surface and other physical factors, the boundary between the scribed line edge and the background is quite blurred, and the influence of noise makes the accurate extraction of the blurred edge a difficult problem. The present invention focuses on developing an automatic detection system for realizing the online accurate detection of the edge of the laser marking line of the industrial solar cell panel. Measurement tasks of the detection system of the present invention: 1. Measure the width of each reticle respectively; 2. Measure the distance between two adjacent reticl...

Abstract

The invention relates to a solar cell laser-marking parameter detection method based on machine vision and a system thereof. According to the method, vision analysis of laser-marking images of a solar cell panel is carried out based on the machine vision technology, laser-marking edges are extracted and high-precision measurement of marking width and spacing of adjacent marked lines is realized. It shows through experiments that the method is stable and reliable and measurement accuracy and repeated accuracy indexes can meet industrial application requirements. The invention also discloses a system for realizing the method.

Description

technical field [0001] The invention relates to the field of detection of solar battery laser marking line parameters. Background technique [0002] With the popularization of computer technology, the traditional industrial field is undergoing tremendous changes. These changes put forward higher requirements for industrial metrology and industrial inspection. The original measurement and inspection technology relying on manual labor is becoming more and more difficult to adapt to the modern development of the industrial field due to the heavy workload and the vulnerability to the subjective factors of the inspectors. How to change the traditional detection and measurement methods to meet the complex needs of reality has become a very important and practical research content in the field of computer and industrial measurement and control. In this context, the new industrial measurement and inspection technology based on industrial image processing technology, computer visio...
