Hanqing Jiang | 姜翰青
I am a Research Director in SenseTime Group Inc., in charge of 3D Reconstruction Team, 3D Vision & Augmented Reality Dept. of SenseTime Research. I am also a member of 3D Vision Committee of CSIG, the secretary general of ZJAI-AR Committee of ZFAI, and an expert of ISO/IEC JTC1.
I obtained my Ph. D degree from Zhejiang University, after which I was a postdoctoral researcher in the State Key Lab of CAD&CG, Zhejiang University, under the supervision of Prof. Hujun Bao and Prof. Guofeng Zhang. My research interests focus on computer vision, including video enhancement, multi-view stereo, 3D reconstruction, and augmented reality. I was the third prize winner of Lu Zengyong's CAD&CG High-tech Awards 2012, and won the best paper award of Chinagraph 2012 and the best paper award of ISMAR 2020.
