| Abstract: | k dimension tree is constructed to trace the boundary points of each hole in point cloud, which are refined and parameterized with a normalized quadric surface. RBF surface is defined to interpolate the boundary points and generate uniformly distributed point mesh in the hole, RBF surface is somehow superior to B-spline surface in its shape-preversing and smooth blending ability. |

| Keywords: | point cloud hole filling radial basis function interpolation surface parameterization |
