Camera output of VGGT

Open Chinafsh opened this issue 8 months ago • 2 comments

Hi, with my own experiments, I found that VGGT is sensitive to weak texture & repetitive textures, which leads to bad camera parameter prediction.

Hi @Chinafsh ,

Yes repetitive textures is kind of expected, especially those like "doppelganger". For weak texture, would you mind sharing some examples? I previously did not notice it will be a huge problem.

Image As this screen shot shows, If I just use first 5 images, it's good. Then I added last three. It failed to estimate the camera of the last three. Thx for ur reply. Do u have any advice ?
