基于埋弧焊V型坡口的三维视觉信息的提取及处理研究

Research on Three-dimensional Visual Information Processing on V Groove of Submerged Arc Welding

介绍了埋弧焊V型坡口三维视觉信息的传感原理 半导体激光器的出射光片与母材成一定角度投向焊缝 ,光片与V型坡口相交成一单光纹 ,位于母材垂直方向的CCD摄像机摄取折线光纹图样 ,送计算机处理 研究了中值滤波、二值化、低通滤波、高通滤波、图像分割、中心取样等措施对图像的处理效果 。

The sensor principle of three-dimensional visual information processing on V groove of submerged arc welding is presented.The shooting light-plate and mother material come to a certain angle to throw to weld seam.Light-plate and V groove intersect to a single vein of light,the CCD camcorder located in the vertical direction to mother material absorbs the image of light vein,which is sent to computer to handle.It has studied the handling effect for image of intermediate value to strain wave,2values melt,low-through,high-through image cutting ,the sampling from center and introduces that how to determine the edge seat of V groove, calculation method of connecting the deviation and depth value.
