Abstract
To improve the efficiency of blade repair, a reverse engineering-based geometry reconstruction method is developed for the normal model creation of a broken blade. The key techniques involved are including the digital measurement of broken blade, point cloud pre-processing, three dimensional models and so on. After the point cloud pre-processing, the segmentation extracts the damaged region from point cloud by a 4D Shepard surface based curvature estimation method. Bezier curve is used to construct the extracted boundary points. Bezier surface is reconstructed by the extracted points and is used to broken space subdivision. At last, a geometry model is built for the preparement of the laser forming repair.
