Webfarthest_point_down_sample (self, num_samples) ¶ Downsample a pointcloud into output pointcloud with a set of points has farthest distance.The sampling is performed by selecting the farthest point from previous selected points iteratively. Parameters. num_samples … WebA Voxel Grid filter allows us to down sample the data by taking a spatial average of the points in the could confined by each Voxel. We can adjust the sampling size by settings the Voxel size along each dimension. The set of points which lie within the bounds of a Voxel are assigned to that Voxel and statistically combined into one output point.
