摘　　要：构建了一种基于视觉传感的焊缝三维模型实时计算系统,包括图像采集程序、图像预处理程序、视觉计算焊缝三维模型程序以及实时显示程序。在未焊接情况和GTAW(钨极氩弧焊)条件下进行试验,结果表明,该系统可以实时地获得被检测焊缝的三维模型,精度能够满足焊接需要,处理速度可以达到20fps,为焊缝自主跟踪奠定了基础。Software system for real-time welded seam 3D model based on vision sensor is constructed, which includes image acquisition, image pre-processing, 3D calculation and real-time control etc. The software and 3D model are confirmed under the condition of no arc and GTAW condition. The results show： this software system could be used to calculate 3D of welded seam in real-time with adequate precision. The velocity for image processing attains 20 frames per second, and lays fundamental for welded seam tracking.
