Large area point cloud holes repairing for the power equipment based on minimum angle iteration

To obtain the completed power equipment 3D models, this paper proposes a point cloud repairing method for the large area holes. Firstly, the initial repairing of the large area point cloud holes are performed based on the minimum angle iteration method. Secondly, a weighting funtion is established using the mean curvature combined with the original insertion vector to make the new patches converge to the center of the holes quickly. Finally, the local density of the hole boundary is used to adjust the spatial coordinates of the insertion points to make the new triangular patches in the large holes area. Experimental results show that the proposed method has less error in accuracy and density compared with other point cloud repairing methods, and it is suitable for the variety of large-area point cloud holes.
