Abstract
In accordance with the characteristics of the butt weld image, this article designs the image processing to extract the size of the weld with according to the butt weld .Firstly, the algorithm of gray closing and mathematical morphology in the method is taken to smooth the interferences of surface scratches and glistens effectively. Secondly, the processed image is detected the image edge with Canny operator, and using the researching method to extract the image character, record the edge coordinate of welding line and achieve the image model to model transformation. Finally, the date information of slope gaps is obtained by the least-squares algorithm to do the edge fit to derive the linear equation. The method in this paper can denoise and protect images has good practicality for its relatively high measurement precision, which are of great value towards the engineering practice.
