From my understanding, the 3d ground truth box can be tilted when projected on bird view, and the intersection between gt box and the anchor is usually not rectangular. However, inside bbox_overlaps it seems you assume that the intersection of two boxes is a rectangle of which the area is calculated by multiplying iw and ih?
