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…

旋转在三维重建中是比较重要的，这里主要对旋转的性质及应用做一些总结。
设某个单位正交基 $(e_1, e_2, e_3)$ 经过一次旋转变成了 $(e_1^{'}, e_2^{'}, e_3^{'})$ 。那么， …
