Ningli Xu I'm a Ph.D. student at The Ohio State University Electrical and Computer Engineering Department working with Dr.Rongjun Qin in Columbus, Ohio. At OSU, I've worked on various photogrammetry and computer vision tasks, including 3D reconstruction, 3D data registration & view sytnthesis. The processed data including satellite, airborne, UAV, street-view images and LiDAR. |

ResearchI'm interested in photogrammetry, computer vision, and robotics. Most of my research is about inferring the realistic and accurate physical world from images. |
