I'm currently a master candidate at the School of Geodesy and Geomatics (SGG), Wuhan University (WHU). My area of research currently focuses on integrated navigation systems and multi-sensor fusion. I'm working on the continue-time-based (B-spline-based) state estimation currently 😃.
- Student at Wuhan University, E-Mail: shlchen@whu.edu.cn.
- A brief introduction about me can be found here.
- I love photography, I also love writing cpp (cplusplus) and creating funny toy libraries.
- Ask me about anything here.
- RIs-Calib: a targetless continuous-time-based multi-radar multi-IMU spatiotemporal calibrator.
- River: a continuous-time-based radar-inertial velocity estimator.
- MI-Calib: a continuous-time-based imu-only multi-IMU spatiotemporal calibrator.
- iKalibr: unified targetless spatiotemporal calibration for resilient integrated inertial systems.

So why is my nickname ULong2 😃? ULong is a data type in C++ that stands for unsigned long integer, which can store a large number, but no negative numbers are allowed. This represents my desire to explore a wide range of knowledge and a positive (non-negative) mindset. Interestingly, Long is also the pinyin for one of the Chinese characters in my name. And the number 2, yes, is my lucky number.
