Abstract: The realisation of weld clearance detection algorithm is the key to vehicle weld detection based on image processing. In this paper, the weld detection area of the acquired image is set on the high resolution CCD image of vehicle weld gap, and then the weld line is detected by combining Hough transform and least squares method. Owing to abnormalities such as broken lines, overlapping lines, and slopes in the detected straight lines, all the checked straight lines are first optimised to extract valid weld straight lines. Finally, the distance of the weld gap is calculated using a formula. The method can be used to measure the weld gap of vehicles quickly and accurately.

Keywords: image processing; weld detection; weld straight line detection.
