Shipbuilding / Underwater Robot Development Three-Dimensional Motion Analysis Device Qualisys
Qualisys Ocean Applications
Wide-ranging support from fishing gear development to shipbuilding, underwater unmanned robot development, and research.
Model ship motion analysis experiments can be conducted over a wide range. Qualisys supports long-range active markers, allowing it to recognize and track model ships located more than 100 meters away, which is impossible with standard markers. By using long-range active markers, it enables motion analysis of objects moving over large distances. Additionally, Qualisys has the world's only optical underwater camera, making it possible to obtain highly accurate underwater motion data that was previously unattainable. This opens up new possibilities for various research areas, including fishing gear, ship propellers, and naval research. Furthermore, by combining ground-based Qualisys cameras with underwater Qualisys cameras, it is also possible to integrate ground data with underwater data.

Company information
We handle high-precision measurement equipment that can be used for ergonomics, building structure, behavior, seismic analysis, fluid analysis, VR, and more, both domestically and internationally. In particular, the Qualisys system we offer is a leading company in the industry that manufactures a three-dimensional optical motion capture system based in Sweden. Qualisys's core technology has been developed since 1989, and based on years of accumulated experience, they develop everything in-house, from hardware like cameras to software. Currently, motion capture systems are used in a wide variety of fields, including medicine and industry. Among their products, there is a unique model that can measure underwater, enabling the acquisition of high-precision three-dimensional data in environments where motion analysis and validation of accuracy were previously impossible.
