Tie 2d and 3d boxs

[PavloZakala]

Hi, can you explain how to tie 2d and 3d boxes?

Did you get this resolved?

Just in case, we do not provide direct correspondence between 2d/3d boxes. That is an interesting task to solve though. One way to get this correspondence naively is to compare the projected 3d boxes and the camera 2d boxes.

camera 2d box: https://github.com/waymo-research/waymo-open-dataset/blob/master/waymo_open_dataset/dataset.proto#L295
