MapDistill: Boosting Efficient Camera-based HD Map Construction via Camera-LiDAR Fusion Model Distillation

no code implementations16 Jul 2024 Xiaoshuai Hao, Ruikai Li, HUI ZHANG, Dingzhe Li, Rong Yin, Sangil Jung, Seung-In Park, ByungIn Yoo, Haimei Zhao, Jing Zhang

To address this, we employ the Knowledge Distillation (KD) idea for efficient HD map construction for the first time and introduce a novel KD-based approach called MapDistill to transfer knowledge from a high-performance camera-LiDAR fusion model to a lightweight camera-only model.

UniMix: Towards Domain Adaptive and Generalizable LiDAR Semantic Segmentation in Adverse Weather

no code implementations CVPR 2024 Haimei Zhao, Jing Zhang, Zhuo Chen, Shanshan Zhao, DaCheng Tao

We devote UniMix to two main setups: 1) unsupervised domain adaption, adapting the model from the clear weather source domain to the adverse weather target domain; 2) domain generalization, learning a model that generalizes well to unseen scenes in adverse weather.

SimDistill: Simulated Multi-modal Distillation for BEV 3D Object Detection

2 code implementations29 Mar 2023 Haimei Zhao, Qiming Zhang, Shanshan Zhao, Zhe Chen, Jing Zhang, DaCheng Tao

Multi-view camera-based 3D object detection has become popular due to its low cost, but accurately inferring 3D geometry solely from camera data remains challenging and may lead to inferior performance.

On Robust Cross-View Consistency in Self-Supervised Monocular Depth Estimation

1 code implementation19 Sep 2022 Haimei Zhao, Jing Zhang, Zhuo Chen, Bo Yuan, DaCheng Tao

Compared with the photometric consistency loss as well as the rigid point cloud alignment loss, the proposed DFA and VDA losses are more robust owing to the strong representation power of deep features as well as the high tolerance of voxel density to the aforementioned challenges.

JPerceiver: Joint Perception Network for Depth, Pose and Layout Estimation in Driving Scenes

1 code implementation16 Jul 2022 Haimei Zhao, Jing Zhang, Sen Zhang, DaCheng Tao

A naive way is to accomplish them independently in a sequential or parallel manner, but there are many drawbacks, i. e., 1) the depth and VO results suffer from the inherent scale ambiguity issue; 2) the BEV layout is directly predicted from the front-view image without using any depth-related information, although the depth map contains useful geometry clues for inferring scene layouts.
