    • Abstract
  • According to the image characteristics in weld seam tracking based on laser structured light, multi-angle Radon transform is used first, and then the singular point in the transformed corresponding to the laser stripe in the original image is found, keep the pixels value unchanged near the singular point and decrease the pixels value far from the singular point, after that inverse radon transform is carried out to recover original image. Finally, fuzzy enhancement method is used to get clear structured image with little noise. This method can bring good effects, and the anti-disturbance performance is well, it costs little additionally, therefore it is suitable for seam tracking based on laser vision.
