Removal method for stair-stepped artifacts based on improved spherical cover algorithm

CHEN Zhong;DUAN Li-ming;WU Zhi-fang;ICT Research Center,Key Laboratory of Optoelectronic Technology and Systems,Ministry of Education,Chongqing University;College of Mechanical Engineering,Chongqing University;China Three Design Industry Engineering Corporation;  
Due to slices distance factor,surface meshes extracted from industrial CT data often contain stair-stepped artifacts.To remove stair-stepped artifacts during mesh generation,a novel removal surface artifacts method was proposed.The k-nearest neighbors of industrial CT point clouds were constructed,the point cloud vector were estimated based on Gaussian weight covariance analysis and the noise from point clouds was removed by bilateral filtering.The point clouds were fitted by quadric error function and the triangular meshes was managed by adaptive spherical cover method.The experimental results showed that the proposed approach could efficiently remove stairstepped artifacts and produce high-quality triangular meshes with a reasonable accuracy.
