I am working on complex multi level buildings, both exterior and interior inthe same model.
I have noticed that when bounding boxes are smaller, there is less dense cloud noise, meaning less post processing/confidence cleaning etc.
Bigger bounding boxes create more residual noise in the dense cloud, so it is easier to divide the model in smaller parts, apart from the RAM / CPU / Autosave (power loss danger) / Issues.
I have also noticed tha depth maps are indeed faster but when there is need to combine LIDAR, dense cloud is necessary. I have also noticed that depths maps medium and dense cloud medium have different quality results. I think dense clouds have better edges.
For my workflow I also need the dense cloud for faster review.
Thank you again.
