%X Wavelet analysis is advantageous in detecting edges.This paper presents a systematic study on V-groove welding laser image and the seam recognizing method of multi-pass welding image.We propose a seam recognizing algorithm based on wavelet transformation and an algorithm to recognize the corner tracking in a multi-pass V-groove.According to the characteristic of multi-pass V-groove,our algorithm outperforms the algorithm of seam recognition in V-groove and uses the technology of template matching,can recognize the corner tracking.
