Hello,
I am still experiencing the same issues of very unstable mesh reconstruction in the V 1.7.. versions as well.
Reducing the image count seems to prevent some reconstruction defects (see attached images) but of course this causes other areas of the mesh to be badly reconstructed as information is missing there.
Masking out defoucs areas also appears to help but the the "Mask defocus areas" option very often chooses the masked areas very unpredictably, masking out quite in focus areas and leaving completly blurry parts. Turning on the "Fix coverage" option pretty much just seems to create masks, that contain all the image parts used in the model - no matter whether they are in focus or not. Strangely enough defocus mask generation appears to be working much better, when creating the defocus masks based on a scaled mesh created in V 1.65 - so I assume, this has something to do with the new DM-generation process too?
It's too bad, the new DM-generation method causes so many problems, as it really is quite impressive, how much more detailed the meshes are in the areas, where the reconstruction works alright. But compared to earlier versions, V1.7.. at the moment is not reliable for my work (close-reange PG of cultural heritage) . This really is quite frustrating and taking up a lot of time testing, recalculating meshes, comparing them, using different versions, etc.
I really hope, this can soon be improved,
Andreas
