AI Technical Summary
During the manufacturing process of pipe tower flanges, the inability to accurately obtain the outer contour of the pipe tower can lead to improper fit between the flange and the pipe tower, resulting in excessive gaps or no fit at all, requiring time-consuming and labor-intensive grinding and correction.
A 3D camera-based image stitching method is adopted. A robot carrying a 3D camera acquires point cloud images of the pipe tower outline, stitches the images, extracts the outer outline of the pipe tower, and combines the Tukey weighted least squares fitting method to fit a straight line outline, generating the inner outline of the pipe tower flange.
It enables rapid and accurate acquisition of the pipe tower profile and generation of a matching flange profile, thereby improving the installation efficiency and connection strength between the pipe tower and the flange.
