【Abstract】 An edge detection algorithm based on the principle theory of image processing is put into the use of seam tracking when there is no other optical source. Proceeding the noise elimination using the wavelet transform after we get the original image according to the real time demand, also we divide the weld image into three parts based on the image segmentation method, on the base of analysis the real weld image and the character of CCD we get the method of weld recognition. From the experiment we come to the conclusion that the weld line edge can be extracted efficiently and clearly, the ambient device can be simplified greatly.更多还原
