About
Hiroshi Tsuchiya is a leading researcher in underwater robotics perception, specializing in acoustic imaging and 3D mapping for autonomous underwater vehicles. His work addresses the fundamental challenge of extracting three-dimensional information from inherently 2D forward-looking sonar (FLS) and acoustic camera systems—a critical problem for robot navigation and mapping in turbid, low-visibility waters where optical cameras fail. Tsuchiya pioneered the "Acoustic Camera-Based Pose Graph SLAM" paradigm, enabling dense 3D mapping in underwater environments (37 citations), and introduced ACMarker, the first fiducial marker system designed specifically for acoustic cameras (24 citations). His innovative contributions include learning-based methods to recover missing elevation angle information from 2D sonar images, as well as the Acoustic-N-Point algorithm for robust pose estimation. With over 100 cumulative citations, Tsuchiya’s work has directly advanced the feasibility of unmanned underwater construction, inspection, and exploration. His research on sonar simulation with ground echo modeling further supports the development and validation of perception algorithms. By bridging the gap between acoustic sensing and 3D computer vision, Tsuchiya is shaping the future of autonomous operations in challenging underwater environments.
