Hello, Z. This is groundbreaking work and it has helped me a lot, but I have a small doubt. on line 233 of the /MonoDETR/tree/main/lib/datasets/kitti)/kitti_dataset.py.the code is: ’‘’ center_3d = objects[i].pos + [0, -objects[i].h / 2, 0] ‘’‘ Why subtract half the height from pos? do you want to user bottom center as real center, and why?
