Abstract:
In order to improve the accuracy of welding seam feature extraction during automatic welding, an adaptive bilateral filtering algorithm is proposed to remove image noise. Firstly, use the adaptive bilateral filter algorithm to denoise the original image, and the binary image of laser stripe is obtained by threshold segmentation. The center line of laser stripe is extracted by combining gray centroid method and least square method. Finally, the coordinates of welding point are obtained by solving the equations of center line of laser stripe. The experimental results show that the method can accurately extract the characteristic corner coordinates of the V-shaped weld, and the accuracy can meet the actual welding requirements.
