orthomosaic from sparse vs dense cloud

[xabierr]

Hi there,

Im reconstructing a highly complex/very-high res vegetation scene from handheld photos.

Just wondering why the quality of the orthomosaic from the (cleaned) sparse point cloud (see attached sparse) is much better than that from depth maps or (cleaned) dense point cloud (see attached dense).

Is it just that the sparse mosaic is smoothed out and looks better but the dense mosaic is more accurate and has better dealt with distortions?

cheers,

Javier

Hello Javier,

Can you please also post the screenshots of the surface used for the orthomosaic generation (DEM or mesh in solid view mode) corresponding to the same area for comparison?
