Investigate the IoU computation for two rotated Bboxes first and then implementĪ unified framework, IoU loss layer for both 2D and 3D object detection tasks.īy integrating the implemented IoU loss into several state-of-the-art 3D objectĭetectors, consistent improvements have been achieved for both bird-eye-view 2Dĭetection and point cloud 3D detection on the public KITTI benchmark. Object detection task with rotated Bboxes. 
Work for axis-aligned 2D Bboxes, which cannot be applied for more general Loss has been introduced for 2D object detection in \cite. To eliminate the performance gap between training and testing, the IoU
Minimize the discrepancy between the predicted and ground truth Bounding Box
However, during the training stage, the commonĭistance loss (\eg, $L_1$ or $L_2$) is often adopted as the loss function to Authors: Dingfu Zhou, Jin Fang, Xibin Song, Chenye Guan, Junbo Yin, Yuchao Dai, Ruigang Yang Download PDF Abstract: In 2D/3D object detection task, Intersection-over-Union (IoU) has been widelyĮmployed as an evaluation metric to evaluate the performance of differentĭetectors in the testing stage.
