Dense reconstruction fails #1531

Closed bgpantojar closed 2 years ago

bgpantojar commented 3 years ago

I run the meshroom pipeline for a set of images (around 100 having partial view of the table -> aimed to be reconstructed) getting the next reconstruction for SfM (you can see how the cameras were distributed):

Although that reconstruction was ok (all the images were registered), the mesh and textured mesh from the dense reconstruction fails as you can see:

Just textured.

From my interest is the dense reconstruction. Do you have any idea why is not working? I assumed that the depth maps are not well assigned for the area that is missing. Is it possible to modify some parameters in the pipeline to make it work? (I was imagining maybe to restrict to use just some images with depth information for instance). Do you recomend a beter set up of the cameras? (maybe one where from each image it is possible to see the full table instead of partially).

I am encountering the same problem: good SfM data, but totally off mesh reconstruction. No solution so far. Having some guidelines/settings to try to approach the problem would be great.
