埋弧焊焊缝跟踪系统数字图像处理方法研究

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。设计了以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，并基于该系统根据焊接现场采集的图像信息，以Sobel边缘检测算子及二值图像连通域像素标记算法相结合，并以Delphi为开发工具对焊缝图像进行处理。试验表明，该算法可以满足埋弧焊焊接生产现场实时处理图像要求，且对光源无严格的要求。

Digital Imagine Processing Method of Weld Tracking System for SAW

The primary problem of real-time weld tracking system is to extract weld information and identify weld center line.A detection weld tracking system is designed which based on the visual CCD sensor and V-series image acquisition card.According to the collected information of welding scene images,weld image is processed with dephi designed tool by combing Sobel edge detection operators and two connected domain image pixel marking algorithm,as a result this algorithm can fulfill the requirements of real-time image processing for SAW,and moreover, it has no strict requests to the light source.
