Description

Hi,

The reconstruction has multiple planes of points. I have tried with different sets of images, sometimes it's very drastic - two almost perpendicular planes, as if the point cloud data was randomly split into parts and then rotated. To clarify attaching a screenshot.

One thing that comes to my mind is that it might be because the images are shot at different angles. Some at 90 degrees and some all the way to 45 degrees. Unfortunately, I cannot share the images, but maybe you have some clues for me.

Research direction

No source files, tests, or entry points are identified in the issue. Start by reproducing the reconstruction with image sets containing the reported angle changes, then trace the point-cloud reconstruction path to determine where differently oriented planes arise; done means identifying a reproducible cause and documenting or fixing it.
