Research on the Method of Position Recognition of Titanium Alloy Pipeline Weld

Aiming at the problem of space pose recognition of titanium alloy pipe weld, this paper designs a pose recognition method based on the combination of ORB and RANSAC algorithm. First of all, preprocess the collected image, then detect the significant feature points in the image quickly, assign the direction to the feature points, and finally match the left and right two images of binocular vision system to realize pose recognition. The experimental results show that compared with SIFT and SURF, the recognition accuracy and efficiency of the designed method are significantly improved.
