Webfeature and the 3D box via the point-based IoU and box-based IoU supervision, respectively. The point-based IoU supervision is proposed to make the network better learn the implicit 3D information encoded in the range image. The 3D Hybrid GIoU loss is introduced to generate high-quality boxes while providing an accurate quality evalua-tion. WebAP [IoU = 0.50] and AP [IoU = 0.75] are reported, as well, since they are more common in the literature and results are more tightened. Loose thresholds are reported as well.
