With the rapid development of ultra high voltage direct current(DC) power transmission technology, the stability of valve base electronics (VBE) device is crucial for ensuring the reliability and efficiency of DC power transmission. The defects in VBE device circuit boards, such as short circuits and failed components, directly affect the system stability. However, the existing detection methods including manual microscopic inspection and automatic detection algorithms are often limited by their low efficiency and insufficient accuracy. In this paper, an automatic visual inspection method based on point pattern matching is proposed to address these challenges. This method significantly improves its detection accuracy and efficiency by generating point patterns that represent key areas and further matching them, which is particularly suitable for rapid quality control on production lines. Experimental validation shows that the proposed method significantly outperforms the traditional methods in terms of detection speed and accuracy, providing an effective technical solution for improving the quality of DC power transmission equipment and demonstrating important practical value.
