Abstract : the image of arc zone of flux - cored underwater wet welding was developed with underwater ccd camera system and composed filter technology . the discussion is mainly focused on the theory of edge detection . an image edge detection method based on median filter and grads algorithm was developed to detect the arc burning zone and arc bubble zone efficiently , which laid the foundation for further analysis of underwater wet welding arc mechanism and process control
文摘:通过复合滤光技术和水下ccd摄像系统，采集出了药芯焊丝水下湿法焊接电弧区域图像，重点论述了边缘检测理论，确定了基于中值滤波和梯度算子的电弧区域图像边缘检测方法，有效地区分了电弧燃烧区域和电弧气泡区域，从而为水下湿法焊接电弧的机理分析及水下焊接过程控制奠定了基础。
