Projecting 3D bounding box to image

[michieljanssen97]

Hi @wittmaan,

I'm struggling to plot a 3D bounding box (ground truth or prediction) to an image. The A2D2 dataset provides the camera intrinsic matrix (K) and the rotation+translation of the camera frame to the global frame. This results in the K [R | T] matrix needed to project a 3D point to 2D space, but it gives me strange results.

Did you find a solution for this?

Thanks,

Michiel

Hi @michieljanssen97,
I also struggled with plotting 3D bounding boxes, but I didn't investigate further on that so far.
Maybe have a look at https://github.com/google-research-datasets/Objectron this seems to provide good examples on plotting 3D bounding boxes.

Sorry, that I couldn't help here,
KR, Andreas

I am having the same problem too, any updates on the issue ??
