Near and far plane?

Open deeplearningfam opened this issue 4 years ago • 1 comments

Hi,

thanks a lot for the great dataset! I was wondering if it is possible to get the approximate near and far plane for the frames? I couldn't find this in the geometry tutorial.

Thanks!

The near and far plane are optimized per frame, and they are available via the projection_matrix, specifically, proj[2, 2] and proj[2, 3]

OpenGL projection matrix )

Which after solving should give you 1000m and 1cm, but depending on calibration it might vary.
