About

Chi Leung Tsui’s research centers on underwater imaging and robotic perception, with a particular focus on developing depth-sensing technologies for challenging aquatic environments. His major contributions lie in adapting and modifying commercial depth cameras—both structured light and Time of Flight (ToF) systems—for underwater use, enabling three-dimensional point cloud imaging and depth measurements. This work directly supports applications such as robotic navigation and haptic feedback for underwater ordnance recovery, bridging the gap between terrestrial computer vision and subsea robotics. His most cited paper, “Using a Time of Flight method for underwater 3-dimensional depth measurements and point cloud imaging” (2014, 11 citations), demonstrates the feasibility of ToF cameras for generating underwater depth data, while his follow-up study on an RGB-D camera system (2016, 2 citations) further refines this approach. Though his citation counts are modest, Tsui’s work is notable for its practical engineering focus, addressing real-world challenges in underwater sensing—a field with growing relevance for marine robotics, environmental monitoring, and defense applications. His research offers a foundation for students and engineers seeking to extend terrestrial depth-sensing methods into the underwater domain.
