Abstract

The invention relates to a welding seam inspection device based on image recognition processing. The welding seam inspection device comprises an intelligent trolley, a detection module and a control module. A camera is installed on the intelligent trolley and used for collecting weld joint pictures, the detection module is used for substituting the collected weld joint pictures into the trained database for comparison and identifying weld joint defects, and the control module is used for controlling operation of the intelligent trolley according to detection results. According to the welding seam inspection device based on image recognition processing, representative welding seam defect pictures are collected on site in a welding site to train the database, so that trained data can be more representative and more conform to the actual situation, treatment according to indications is facilitated, different databases can be replaced according to different detected welding seam attributes, and the detection efficiency is improved. The detection flexibility and the diversity of processed data are greatly enhanced, and the detection efficiency is high.

Description

technical field [0001] The invention relates to the fields of electronic control and machine vision, in particular to a welding seam inspection device based on image recognition processing. Background technique [0002] Due to the influence of welding process or equipment condition deviation, residual stress state, metallurgical factor changes, etc., welding products often produce different degrees and numbers of pores, cracks and other defects in the welding seam, or the welding seam Due to the failure of complete fusion or penetration of individual positions, the post-weld quality inspection will be carried out on the weld. In the existing weld inspection, defects such as undercut, slag inclusion, pores, and cracks on the surface of the weld are generally inspected manually or with the naked eye. Low-magnification magnifying glass for observation is inefficient and cannot guarantee accuracy. In some extreme conditions, such as inspection of internal welds in pipelines, it ...
