General / Tiled Model Banding Problem
« on: April 24, 2022, 12:16:47 PM »
Hi,
I've been experimenting with a large dataset, trying to learn Metashape. I'm trying to produce a full tiled model of the dataset and have run into a problem with square cross banding and black holes (please see attached image). The banding seems to be across the whole area and doesn't match with any flight lines, it seems this is being produced by the processing.
My workflow was generally to:
Alignment -> produce dense cloud (in high, without color) -> produce DEM and orthomosaic -> produce mesh (in high, without color) - > produce tiled model based on mesh source (in high).
I did have quite a few photos unticked in the reference window as the GPS quality was affecting the accuracy of the alignment, but the mesh model seems very good.
I have already produced very good tiled models from smaller regions of the dataset that worked just fine and without any banding. For these sets I just produced the tiled model straight after producing the dense cloud and selected the dense cloud as source.
I will try to run the tiled model again tonight based on dense cloud rather than the mesh, but I wonder if anyone has run into this problem before and has any tips?
Many thanks,
Paul
