If I already have a priori LiDAR data for the target environment, as you introduced, I can directly skip the second step and replace the sparse point cloud generated by SFM with this a priori point cloud data, right?
But in the second step, if I understand correctly, the sparse point cloud generated by SFM should have some feature information associated with it besides the 3D coordinates. How should I associate these feature information for my own point cloud data?
