主 题:3D object detection Multi-sensor fusion Uncertainty estimation Semantic segmentation PointPainting
摘 要:In recent years,camera-and lidar-based 3D object detection has achieved great ***,the related researches mainly focus on normal illumination conditions;the performance of their 3D detection algorithms will decrease under low lighting scenarios such as in the *** work attempts to improve the fusion strategies on 3D vehicle detection accuracy in multiple lighting ***,distance and uncertainty information is incorporated to guide the“paintingof semantic information onto point cloud during the data ***,a multitask framework is designed,which incorpo-rates uncertainty learning to improve detection accuracy under low-illumination *** the validation on KITTI and Dark-KITTI benchmark,the proposed method increases the vehicle detection accuracy on the KITTI benchmark by 1.35%and the generality of the model is validated on the proposed Dark-KITTI dataset,with a gain of 0.64%for vehicle detection.
