Brief Bio

I'm Xinpu, a passionate and self-motivated explorer of 3D vision research. Currently, I'm a Ph.D. student (Jan. 2023 - ) at the National University of Defense Technology (NUDT), supervised by Profs. Zhen Liu, Yulan Guo and Hanyun Wang. I received my Master and B.E. degrees from NUDT in 2022 and 2020, respectively. My research interests focus on 3D Computer Vision, particularly on object detection and point cloud processing.
