EPNet++: Cascade Bi-directional Fusion for Multi-Modal 3D Object Detection

1 code implementation21 Dec 2021 Zhe Liu, Tengteng Huang, Bingling Li, Xiwu Chen, Xi Wang, Xiang Bai

Recently, fusing the LiDAR point cloud and camera image to improve the performance and robustness of 3D object detection has received more and more attention, as these two modalities naturally possess strong complementarity.

EPNet: Enhancing Point Features with Image Semantics for 3D Object Detection

1 code implementation ECCV 2020 Tengteng Huang, Zhe Liu, Xiwu Chen, Xiang Bai

In this paper, we aim at addressing two critical issues in the 3D detection task, including the exploitation of multiple sensors~(namely LiDAR point cloud and camera image), as well as the inconsistency between the localization and classification confidence.
