I am a final year Master student at BBNC Lab, Department of Automation, Tsinghua University, supervised by Prof. Dr. Xiangyang Ji. I got my bachelor's degree also from Department of Automation, Tsinghua University. I'm having a great time as an exchange project student in CVG, ETH Zurich, supervised by Prof. Dr. Marc Pollefeys, working with Dr. Francis Engelmann and Fangjinhua Wang.

My research interest lies in 3D computer vision, especially scene reconstruction and understanding, human-scene interaction and pose estimation.

Some of my close colllaborators include PD Dr. Federico Tombari, Dr. Yan Di, Dr. Gu Wang, Ruida Zhang, Xingyu Liu.

I am invited as a reviewer for CVPR, ICCV and ECCV. I'm a student member of Chinese Society of Image and Graphics (CSIG).

News

[Feb, 2025] My first-authored paper OpenFunGraph is accepted by CVPR 2025. It proposes a functional scene graph representation to model indoor functionality and interaction.
[Feb, 2025] Two co-authored papers are accepted by CVPR 2025. UNOPose for unseen object pose estimation with an RGB-D reference. GIVEPose for RGB-based category-level object pose estimation.
[Oct, 2024] Two co-authored papers are presented at ECCV 2024. D-SCo for diffusion-based hand-held object reconstruction. LaPose for RGB-based category-level object pose estimation.
[May, 2024] My co-first-authored paper RaSim is presented in ICRA 2024. It involves a useful pipeline for simulating real-world depth scan and completing defected depth maps.
[Feb, 2024] Three my (co-)first-authored papers are accepted by CVPR 2024, including MOHO for single-view hand-held object reconstruction without 3D supervision; KP-RED for shape analysis without part annotations; ShapeMatcher for indoor shape analysis from arbitrary poses.
[Feb, 2024] I'm approved to enroll as an project mobility student to CVG, ETH Zurich. Great thanks for Prof. Marc Pollefeys for giving this opportunity!
[Oct, 2023] Our work GPose2023 wins BOP Challenge 2023, ICCV R6D Workshop. It's honored for me to give an oral presentation in ICCV 2023.
