Abstract
Methods for cleaning a point cloud using an electronic computing device are presented, the method including: causing the electronic computing device to decompose the point cloud into a number of cell voxels; removing a number of outlier cell voxels; subsampling the point cloud; removing a first number of outlier points; removing a number of double surfaces; and removing a second number of outlier points. In some embodiments, method further include outputting a clean point cloud to file. In some embodiments, the causing the electronic computing device to decompose the point cloud further includes: reading into memory a number of points corresponding with the point cloud; specifying a cell voxel size; creating a cell grid to chunk the point cloud into a number of smaller sets; sorting the number of points into the number of cell voxels; and merging all point clouds.
