Chong Xia | 夏冲

I'm a second-year PhD student in the Department of Electronic Engineering at Tsinghua University , advised by Prof. Yueqi Duan. In 2024, I obtained my B.Eng. in the Department of Automation, Tsinghua University.

My research interest lies in 3D Vision and Embodied AI. If you are interested in working with me, please feel free to drop me an email.

    dise SimRecon: SimReady Compositional Scene Reconstruction from Real Videos
    Chong Xia*, Kai Zhu*, Zizhuo Wang, Fangfu Liu , Zhizheng Zhang , Yueqi Duan
    Computer Vision and Pattern Recognition (CVPR), 2026
    [arXiv] [Code] [Project Page]

    In this paper, we propose a novel compositional scene reconstruction framework, coined SimRecon, that implements a "Perception-Generation-Simulation" pipeline with specialized bridging modules to ensure high visual fidelity and physical plausibility.

    dise OnlineX: Unified Online 3D Reconstruction and Understanding with Active-to-Stable State Evolution
    Chong Xia, Fangfu Liu , Yule Wang, Yize Pang, Yueqi Duan
    Finding of Computer Vision and Pattern Recognition (CVPR), 2026
    [arXiv] [Code] [Project Page]

    To enable online 3D reconstruction from streaming images, we propose OnlineX, a framework that jointly models visual appearance and language fields through a novel decoupled memory state evolution.

    dise ScenePainter: Semantically Consistent Perpetual 3D Scene Generation with Concept Relation Alignment
    Chong Xia, Shengjun Zhang , Fangfu Liu , Chang Liu, Khodchaphun Hirunyaratsameewong, Yueqi Duan
    International Conference on Computer Vision (ICCV), 2025
    [arXiv] [Code] [Project Page]

    In this paper, we introduce a novel world generation framework, coined ScenePainter, to direct the iterative scene generation process with semantically consistent scene concepts and relations.

    dise Memory-based Adapters for Online 3D Scene Perception
    Xiuwei Xu* , Chong Xia*, Ziwei Wang , Linqing Zhao , Yueqi Duan , Jie Zhou , Jiwen Lu
    Computer Vision and Pattern Recognition (CVPR), 2024
    [arXiv] [Code] [Project Page]

    We propose a model and task-agnostic plug-and-play module, which converts offline 3D scene perception models (receive reconstructed point clouds) to online perception models (receive streaming RGB-D videos).
