Fujitsu has successfully used LiDAR and artificial intelligence (AI) technology to create a digital twin of the ocean, which supports marine conservation efforts and contributes to carbon neutrality and biodiversity initiatives. The technology, based on real-time measurement techniques originally developed for an evaluation support system with the International Gymnastics Federation, scans the ocean from autonomous underwater vehicles, even in challenging conditions such as currents and waves.

Artificial intelligence is then used to restore color and contour to underwater subjects, creating high-resolution 3D images that enable precise identification and measurement of targets down to several centimeters, even in murky waters. In a successful field test conducted near Ishigaki Island, Okinawa Prefecture, Japan, with the National Institute of Naval Research and the National Institute of Maritime, Port and Aerospace Technology, Fujitsu obtained precise 3D data for mapping coral reefs.

In the future, Fujitsu plans to expand its use of this technology to map seaweed beds, which play a key role in carbon absorption. By creating a seaweed digital twin, Fujitsu aims to support companies and local governments in assessing carbon storage, implementing conservation measures, cultivating new seaweed beds and promoting biodiversity in seaweed reefs. This technology has the potential to have a significant impact on marine conservation efforts and contribute to broader environmental initiatives.
