    Publications

    Satellite to GroundScape - Large-scale Consistent Ground View Generation from Satellite Views
    Ningli Xu, Rongjun Qin
    CVPR 2025 (2878/13008, top 22.1%)
    arxiv | project page

    Sat2groundscape is a framework that transforms satellite imagery into realistic street view sequences using diffusion models, and a constrained optimization strategy to enhance cross-view synthesis quality.

    Skyeyes: Ground Roaming using Aerial View Images
    Zhiyuan Gao*, Wenbin Teng*, Gonglin Chen, Jinsen Wu, Ningli Xu, Rongjun Qin, Andrew Feng, Yajie Zhao
    WACV 2025
    arxiv | project page

    SkyEyes is a framework that transforms aerial imagery into realistic street view sequences using 3D Gaussian Splatting, diffusion models, and a constrained optimization strategy to enhance cross-view synthesis quality.

    Geospecific View Generation -- Geometry-Context Aware High-resolution Ground View Inference from Satellite Views
    Ningli Xu, Rongjun Qin
    ECCV 2024 (Oral Presentation, 200/8585, top 2.3%)
    paper | dataset | project page | Invited talk at Voxel51

    The first work applying diffusion-based method to tackle satellite-to-ground view generation task. It performs ground-view synthesis conditioning on the weak building facades information from satellite images.

    Large-scale DSM registration via motion averaging
    Ningli Xu, Rongjun Qin
    ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2024 Best Paper Award (1/229)
    paper | slides

    Want ICP (iterative closes point) be applied to terrain-scale DSMs (digital surface model) and even multiple noisy DSMs? Check out the proposed DSM-ICP, which applies a fast and exact nearest neighbor search method leveraging the grid structure of DSM.

    Multi-tiling neural radiance field (NeRF)—geometric assessment on large-scale aerial datasets
    Ningli Xu, Rongjun Qin, Debao Huang, Fabio Remondino
    The Photogrammetric Record , 2024 (Cover article of 12/2024 issue)
    paper | video | code

    NeRF vs Multi-view stereo? We propose multi-camera tiling technique to enable NeRF on large-scale aerial datasets and further conduct experiment to compare their geometry reconstruction performance.

    Point cloud registration for LiDAR and photogrammetric data: A critical synthesis and performance analysis on classic and deep learning algorithms
    Ningli Xu, Rongjun Qin,Shuang Song
    ISPRS Open Journal of Photogrammetry and Remote Sensing , 2023
    paper | awesome-registration-papers

    Review and evaluation experiment of feature-based and ICP-based registration methods on photogrammetry and LiDAR data.

    A volumetric change detection framework using UAV oblique photogrammetry – a case study of ultra-high-resolution monitoring of progressive building collapse
    Ningli Xu, Debao Huang, Shuang Song, Xiao Ling, Chris Strasbaugh, Alper Yilmaz, Halil Sezen, Rongjun Qin
    International Journal of Digital Earth , 2021
    paper | video

    Monitoring of progressive building collapse using photogrammetry technique.
