How to get the point cloud for alignment in blender #61

hello, thanks for your work! I want to align scene and human in blender and I'm not sure how to get the point cloud of scenes and human

The point cloud of the scene is reconstructed by the colmap, and exported as .ply file using Open3D library. The point cloud of the human is the vertex of the SMPL model also exported using O3D. We concatenate multiple human point clouds from the motion sequence to form a single point cloud, to help the alignment.

Thanks for your answer. But I'm not sure in blender I should align by adjusting the scene model or the character mode
