Fast 3D object symmetry detection for point cloud

In this article, we proposed a fast algorithm of symmetry detection 3D model. First, we used the PCA algorithm for initial symmetry detection. Then, using exhaustive search of symmetry planes passing through the center of gravity about the initial symmetry plane, we determined the optimal symmetry plane with the help of the modified Hausdorff metric. The accuracy and speed of the proposed symmetry detection algorithm on real and synthetic data are compared to the PCA algorithm.
