About

Shiwen Wang is an emerging researcher specializing in sensor calibration, multi-modal sensor fusion, and state estimation for mobile robotics and autonomous systems. His work centers on developing robust, targetless spatiotemporal calibration frameworks that enable seamless integration of heterogeneous sensor suites — including LiDARs, cameras, IMUs, and radar — using continuous-time trajectory optimization techniques. Wang's most significant contributions lie in addressing the fundamental challenge of precisely synchronizing and calibrating multi-sensor systems without requiring specialized calibration targets, making these methods practically deployable in real-world robotic applications. His most-cited work on multi-LiDAR multi-IMU calibration (19 citations) demonstrates his ability to tackle increasingly complex sensor configurations as hardware costs continue to decline. Complementary efforts, including MI-Calib for multiple IMU calibration and a targetless camera-IMU calibration framework, highlight the breadth and systematic nature of his research agenda. Beyond calibration, Wang has extended his expertise to velocity estimation, developing River, a tightly-coupled radar-inertial estimator that broadens perception capabilities in challenging environments. With a growing citation record accumulated largely within just two years, Wang is establishing himself as a promising contributor to the autonomous robotics and sensor fusion community.
