| 摘 要： | 焊缝图像的边缘提取是实现焊缝视觉跟踪的一个重要环节.用抗噪膨胀腐蚀型形态学算子对单边V型坡口横焊焊缝二值图像进行了边缘提取,并与传统的Roberts算子、Sobel算子、Canny算子、LOG算予以及典型的形态学腐蚀算子、膨胀算子和膨胀腐蚀算子的边缘提取效果进行了对比.结果表明,抗噪膨胀腐蚀型算子具有非常强的抗噪性,可以有效地提取出焊缝图像边缘,更利于后续的焊缝特征点提取.

| Abstract: | The edge detection of seam image is an important step to realize the vision seam tracking.The edge detection of seam binary image in horizontal position welding of single bevel groove was implemented by using an improved morphological edge detection operator:anti-noise-dilation-erosion operator.The edge detection result was compared with those of traditional detection operators,such as Roberts operator,Sobel operator,Canny operator,LOG operator etc,and those of typical morphological edge detection operators... |
