About

Dr. Peidong Liu is currently an Assistant Professor of Computer Science at Westlake University, Hangzhou, China. He got his PhD degree from the Department of Computer Science at ETH Zurich, under the supervision of Prof. Marc Pollefeys. He got both his master and bachelor degrees in Electrical Engineering from National University of Singapore. His research bridges 3D computer vision and robotics, focusing on visual spatial intelligence (SpatialAI) - developing algorithms that enable machines to perceive, understand, and interact with their 3D environment through visual data. Details are as follows:

  • Perception: 3D/4D reconstruction and generation;
  • Reasoning: 3D scene understanding and reasoning;
  • Action: 3D vision for robot;
