Question About Scene Reconstruction with Single-Camera Data #94

Open zhicong01 opened 1 week ago

zhicong01 commented 1 week ago

Thank you for your excellent work!
When conducting experiments using data collected with my single camera, I noticed that out of 1200 original images, only 350 were retained after processing. Additionally, the latter part of the scene could not be reconstructed.

Could you please provide some insight into what might be causing this issue?
Thank you very much for your help!

in the outfile of generate_colmap: image

I think this problem might occur before the image simplification step.

This may be because sfm failed. Monocular SfM for pure forward motion often fails without extrinsics. You can refer to https://github.com/graphdeco-inria/hierarchical-3d-gaussians/issues/3#issuecomment-2487669694
