1. Graduate Student Researcher (Jan 2015 - Present)
Control and Robotics Lab, University of California, Riverside
- Bucket wheel reclaimer calibration, surface reconstruction and automatic control:
Developed a method to calibrate LiDAR-GPS extrinsic parameter. Developed a software that manages a point cloud and reconstructs a 3D surface in real time using 2D LiDARs and GPS receivers mounted on a bucket wheel reclaimer.
- Mixed Sample Rate Nonlinear Smoothing:
Wrote a tutorial on different smoothing methods for the nonlinear model where the sensors have different sampling rate. Simulated the algorithms in MATLAB for a 2D differential robot.
- Roadway feature mapping using mobile laser scanner (LiDAR):
Developed a complete process to map roadway features for intelligent driving assistance systems and future self-driving cars from 3D mobile laser scanner and GPS data. The algorithm was used to generate J2735 map of 11 intersections of California ITS testbed in Palo Alto.
- Roadway feature extraction from 3D point clouds using a graph-based clustering approach:
Developed a graph based clustering approach to extract roadway features directly from 3D point cloud. This method extracts features without any rasterization which preserves point cloud accuracy without increasing computational requirement.
