💫About Me

I am currently a second-year M.S.E. student at ISPC Lab of Tongji University and advised by Prof. Guang Chen. Before this, I obtained the bachelor’s degree in Vehicle Engineering at Tongji University.

My research interests mainly focus on 3D Computer Vision, including Dynamic Reconstruction, Generative Models and Autonomous Driving. In 2022, I was a research intern at OpenDriveLab of Shanghai AI Laboratory advised by Prof. Hongyang Li. From 2024, I interned at CCVL Lab of Johns Hopkins University advised by Bloomberg Distinguished Professor Alan L. Yuille. And I have been a visiting student at SU Lab of UC San Diego advised by Prof. Hao Su, where I spent a wonderful time in La Jolla.

Now I’m looking for Ph.D. (Fall 2025) opportunities, please feel free to drop me an email📬!

Weiyi Xue∗, Zehan Zheng∗, Fan Lu, Haiyun Wei, Guang Chen, Changjun Jiang
NeurIPS, 2024
[Paper] | [Code] | [Poster]
Global neural optimization framework for pose-free LiDAR reconstruction, which provides explicit geometric priors and achieve simultaneous large-scale multi-view registration and novel view synthesis.

RCDN: Towards Robust Camera Insensitivity Collaborative Perception via Dynamic Feature-based 3D Neural Modeling
Tianhang Wang, Fan Lu, Zehan Zheng, Guang Chen, Changjun Jiang
NeurIPS, 2024
[Paper] | [Slides] | [Poster]
Collaborative perception framework with BEV feature based static and dynamic fields, which can recover failed perceptual messages sent by multiple agents and achieve high collaborative performance with low calibration cost.

PersFormer: 3D Lane Detection via Perspective Transformer and the OpenLane Benchmark
Li Chen∗, Chonghao Sima∗, Yang Li∗, Zehan Zheng, Jiajie Xu, Xiangwei Geng, Hongyang Li, Conghui He, Jianping Shi, Yu Qiao, Junchi Yan.
ECCV, 2022 (Oral)
[Paper] | [Code] | [Blog] | [Slides] | [Video] (4min) | [Talk] (50min) | [Poster]
End-to-end monocular 3D lane detector with a novel Transformer-based spatial feature transformation module which generates BEV features by attending to related front-view local regions with camera parameters as a reference.
