Fujitsu Utilizes LiDAR and AI to Develop Digital Twin of the Ocean for Marine Conservation Initiatives

Fujitsu’s Digital Twin of the Ocean: Boosting Marine Conservation Efforts and Carbon Neutrality Initiatives through LiDAR and AI Technology

Fujitsu is using LiDAR and artificial intelligence (AI) to create a digital twin of the ocean, which supports marine conservation efforts and contributes to carbon neutrality initiatives and biodiversity. The technology involves acquiring high-resolution 3D data of organisms and artificial structures to accurately replicate the ocean environment.

The technology behind the digital twin project is based on a real-time measurement technique developed by Fujitsu for its ‘Evaluation Support System’, in collaboration with the International Gymnasts Federation, that uses LiDAR technology. This technique allows for scanning from autonomous underwater vehicles, even in challenging conditions such as strong currents and waves.

By applying artificial intelligence to the data collected, the system is able to restore the color and contour of underwater subjects, creating detailed and accurate 3D images. This technology enables the identification and precise measurement of targets up to several centimeters in murky waters, as explained by Fujitsu in a press release.

Fujitsu conducted a successful field test of this technology near Ishigaki Island, Okinawa Prefecture in Japan, in collaboration with the National Maritime Research Institute and the National Institute of Maritime, Port and Aviation Technology. Precise 3D data was obtained to map coral reefs, showcasing the technology’s potential for marine conservation efforts.

In addition to coral reefs, Fujitsu plans to expand the capabilities of this technology to include seaweed beds by fiscal year 2026. By creating a digital twin of seaweed reefs, companies and local governments can estimate the carbon stored in seaweed beds, implement measures for conservation and cultivation
