利用自行建立的基于计算机视觉的脉冲 TIG焊熔池几何参数检测系统 ,从工件的正面利用 CCD传感器拍摄到了清晰的熔池图像。针对熔池图像的特点 ,设计了快速有效的图像处理算法 ,实时检测出了熔池的最大宽度、半长、后部面积、后拖角等重要几何参数 ,为下一步对焊接质量实时控制打下了良好基础 Based on the computer-aided pulse TIG welding pool geometric parameter detection system established by ourselves, a clear pool image was captured by the CCD sensor from the front of the workpiece. According to the characteristics of the molten pool image, a fast and effective image processing algorithm is designed, and the important geometric parameters such as the maximum width, half length, rear area and trailing angle of the molten pool are detected in real time, laying the foundation for the real-time control of welding quality in the next step A good foundation
