Edge Voxel Erosion for Noise Removal in 3D Point Clouds Collected by Kinect©
Yan Wan, Li Yao, Jianpeng Jiang, Bugao Xu · 2020
When the human body point cloud is captured by Kinect©, the edge voxels with lower accuracy need to be removed to ensure the precision of the 3D point cloud patches. However, there is no existing erosion algorithm for 3D voxel. This paper proposes a 3D contour voxels erosion algorithm based on 2D image erosion algorithm, which maps the erosion mode of 2D contour pixels to the 3D contour voxels, and eliminating the contour voxels with low accuracy to optimize the 3D human body point cloud.
