# Biography

Yu Chen is a SLAM algorithm engineer in Segway Robotics. He obtained his M.S. degree in Electronic Engineering and Computer Science School, Peking University, where he joined the 3D reconstruction group of EECS, he is advised by Prof. Yisong Chen and co-supervised by Shuhan Shen. His research interests mainly include 3D reconstruction, which include Structure-from-Motion (SfM), distributed optimization, Simultaneous Localization and Mapping (SLAM), semantic reconstruction. He used to be a web developer when he studied in BUAA. His dream is to build the world by computer vision techniques. His career in the future is classified…

# Experience

#### TuSimple

Apr 2019 – Jul 2019 Beijing
Responsibilities include:

• I researched in the globally optimal guaranteed rotation averaging optimization approaches. I was supervised by Dr. Ji Zhao.
• I improved global rotation averaging approach by x100 times in efficiency, without precision loss compared with state-of-the-art in large scale datasets.
• I make the global rotation averaging optimization approach practicable in SLAM backend.

#### Megvii

Sep 2018 – Dec 2018 Beijing
Responsibilities include:

• I implemented a mobile-based real-time 3D reconstruction framework utilizing the raw images and depth images as input.
• I applied depth fusion-based approach for front-end reconstruction, multi-view based approach for backend texture mapping.
