i used another tools to do this ,for the same input, and i got iou score 1.0 i don't know whether you uploaded the function falsely or what. aha, the experiment result from what.

We followed prior work and used the VoteNet codebase for our evaluations (https://github.com/facebookresearch/votenet/blob/main/utils/box_util.py#L92) It's quite surprising that it returns 0. Can you check that codebase and see if it returns zero too?

i do this @imisra

i used mmdet3d to produce corners, with lidar, camera, depth coordinate sys, finally still zero.
