Sheng Cao's home page
I am a master's student in Mechanical Engineering at Huazhong University of Science and Technology, working in the State Key Laboratory of Intelligent Manufacturing Equipment and Technology. I am supervised by Prof. Wenlong Li.
My work focuses on:
- robotic perception and geometric estimation in large-scale environments;
- point cloud registration, reconstruction, and spatial understanding;
- multi-sensor fusion and calibration for autonomous robotic systems.
