基于CCD的埋弧焊焊缝跟踪系统数字图像处理方法

Digital image processing methods of tracking system based on CCD for submerged arc weld

提取焊缝信息、确定焊缝中心是实时焊缝跟踪系统要解决的首要问题,本文介绍了以CCD视觉传感器和V系列图像采集卡为核心的焊缝检测跟踪系统,基于该系统并根据焊接现场条件采集的图像信息,结合Sobel边缘检测算子及二值图像连通域像素标记算法对焊缝图像进行处理,该算法可以满足埋弧焊焊接生产现场实时处理图像要求,且对光源无严格要求。

The first problem that has to be resolved by the seam tracking system is to extract weld information and identify weld center in real-time. The article here specially introduced the seam detection tracking system which was focused on the visual CCD sensor and V-series image acquisition card. Based on the system and according to welding scene images collected information, combined with Sobel edge detection operators and two connected domain image pixel marking algorithm for the processing of weld image, this algorithm may fulfill the requirements of image processing, moreover, it has no strict requests to the light source.
