The paper analyses edge detecting arithmetic operator antijamming ability of prewitt,robert,sobel,log and canny,studies the technology for detecting the image edge of Vgroove,and analyses the experiment results of edge detecting with different edge detecting arithmetic operators.With the advantages of the wavelet analysis edge detecting,finds out signal break point and the edge of image.Because edge of Vgroove is not so good,central sampling is used after wavelet transform for remedy disadvantage of wavelet transform.At last ideal result are gained after adopting Hough transform.
