Embodiment Construction
[0036] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] figure 1 An alternative flowchart showing the algorithm, as in figure 1 As shown, a large-scale three-dimensional rivet concavo-convex visualization method based on multi-level fitting of the present invention includes:
[0038] S1, acquire the image of the rivet to be processed, extract the rivet outline by using the RANSAC circle fitting algorithm, and acquire the parameters of the rivet outline circle;
[0039] S2, according to the rivet contour circle parameters extracted in S1 and the RANSAC plane fitting algorithm, extract the rivet head point cloud;
[0040] S3. According to the rivet head point cloud and the non-rivet point cloud, calculate and visually display the concave and convex amount of the rivet.
[0041] By applying the technical solution of the present invention, the concave-convex amount of the rivet can be displaye...
