I'm encountering an unexpected issue while downsampling point clouds using Open3D. Even after applying the downsampling process, I'm still finding duplicate points in my resulting point cloud.
I understand that the original data might contain duplicates, but I'm puzzled as to why the downsampling operation would retain these duplicates. I'm using the following code for downsampling:
downsampled_pcd = pcd.voxel_down_sample(voxel_size)
The point cloud is created with:
o3d.t.geometry.PointCloud(map_to_tensors)
Does anyone have experience with this issue? Could there be a specific reason why downsampling might not effectively remove duplicates, or is there a potential error in my code? I'd appreciate any insights or suggestions on how to address this problem.
