Jiadai Sun 孙家岱

I obtained my Master’s degree in April 2023 from Northwestern Polytechnical University (NWPU), with the supervision of Prof. Yuchao Dai, once again with the honor of Outstanding Graduate. And I received my Bachelor’s degree in July 2020 from the School of Computer Science of NWPU, with the honor of Outstanding Graduate.

Currently, I am a Perception Algorithm Engineer at Intelligent Driving Technology (IDT) of Baidu Inc. I spent about a year of pleasant and fulfilling internship at the Robotics and Autonomous Driving Lab of Baidu Research, and working on a research topic about Scene Reconstruction and Novel View Synthesis. Before that, I have been working very closely with Xieyuanli Chen on a research topic about LiDAR-Based Moving Object Segmentation at Haomo.AI. I used to be a Research Intern on topics related to 3D Scene Reconstruction and Understanding at 3D&AR Group @ MIG of SenseTime Research supervised by Jiaming Sun and Prof. Xiaowei Zhou (CAD&CG, ZJU) from October 2019 to May 2020.

During my undergraduate study, I worked in CVR-Lab supervised by Prof. Yuchao Dai as a Research Assistant on LiDAR/Visual 3D Registration and Reconstruction, Dual LiDAR calibration, etc. I’ve served in the NWPU Dancing Robot Research And Training Base - Rescue Robot Group Team - Explorer for two years as a Robot Software Engineer and Team Leader since July, 2017. As usual, we participate in RoboCup Rescue Robot League Regional Open Competitions, and my main contribution is about SLAM, Robot Localization and Navigation, Path Planning, etc.
