Ningli Xu

I'm a 5th year Ph.D. student at The Ohio State University working with Rongjun Qin in Columbus, Ohio.

During my Ph.D. period, I worked on 3D reconstruction of multi-source data including satellite, aerial, UAV, ground-view images; 3D registration of cross-view/cross-source data; View synthesis & generation of ground views from aerial & satellite views.

Most my works are related to: Computer vision, Generative AI, Diffusion, NeRF, Guassian Splatting. Some works are highlighted.

	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.
