Mismatch between 2D bbox and projected 3D bbox after affine transformation #71

Closed cswenhaowu closed 1 year ago

cswenhaowu commented 1 year ago

Hi, thanks a lot for the excellent work.

I have a question about the affine transformation augmentation. I applied RandomWarpAffine on KITTI dataset, and I drew the 2D bbox and projected 3D bbox (with P2 modified by RandomWarpAffine). I found that the 2D bbox can well enclose the object, but the projected 3D bbox will deviate from the object. Could you please help me solve the problem? Or is there any temporal workaround here? Thanks for your help in advance.

Hi, sorry for my mistake when projecting and drawing 3D boxes on the image plane. And thanks again for the great work.

Same problem... So which one should I use during typical 2d detection? The provided 2d bbox or projected 3d bbox?
