- W2393899807 abstract "In order to meet the real-time tracking need of welding seam in submerged arc welding(SAW) equipment and find the center of welding seam timely and accurately,a zonal auxiliary light source perpendicular to welding seam was used to make the welding seam image obtained with CCD camera generate obvious V-shaped distortion.The noise points in the image were removed with a denoising program,and the points on both sides of V-shaped image were found out.The least square method was adopted to obtain the optimal fitting lines for two sides of V-shaped light band distortion quickly and accurately,and the intersection point of two fitting lines was calculated to find out the center of welding seam.The recognition technology of V-shaped groove welding seam in SAW based on the least square method can reveal the characteristics of welding seam,and has such advantages as fast processing speed and good system stablity." @default.
