面阵CCD摄像机对TIG焊焊缝特征的识别

Welding seam trait recognition to TIG welding base on planer CCD camera

介绍了一种在TIG焊对接条件下基于面阵CCD图像处理方式的实时自动跟踪系统.由VisualBasic6.0开发出准确识别焊缝位置的软件.对识别的整个过程作了详细的分析,并提供了具体的算法.实验表明,系统对TIG焊的对接和搭接焊缝有很好地处理效果,对大幅度折线焊缝也能很好的跟踪(折线角>68°),处理速度>100ms.

This paper introduces an auto tracking system based on planer CCD image processing under a sort but jointed of TIG welding. with Software exploited by visual basic 6.0, welding seam position. This paper makes detailed analyses and provides specific algorithm to the whole discriminating process can be accuratecy identified.Test shows that this way can exhibit good result to butt joint and lap joint of TIG welding and accurately abstract welding seam out, to the welding seam of large magnitude dogleg angle shows good tracking effect(dogleg angle<68°) and procession speed <100 ms.
