Using LiDAR and AI, Fujitsu creates digital twin of ocean to support marine conservation efforts

Fujitsu is utilizing LiDAR and artificial intelligence (AI) to create a digital replica of the ocean. This technology supports marine conservation efforts, contributes to carbon neutrality initiatives, and promotes biodiversity. The underlying technology for building this digital twin is based on a real-time measurement technique that Fujitsu initially developed for its Evaluation Support System in collaboration with the International Gymnasts Federation.

This innovative approach employs autonomous underwater vehicles to scan the ocean in challenging conditions such as currents and waves. Artificial intelligence is then used to restore color and contour to underwater subjects, resulting in high-resolution 3D images. This allows for precise identification and measurement of targets up to several centimeters, even in murky waters.

Fujitsu recently completed a successful field test near Ishigaki Island, Okinawa Prefecture in Japan, in partnership with the National Maritime Research Institute and the National Institute of Maritime, Port, and Aviation Technology. During this test, they obtained accurate 3D data to map coral reefs. In the future, Fujitsu plans to expand its use of this technology to map seaweed beds, which play a vital role in absorbing carbon dioxide from the atmosphere.

By creating a digital twin of seaweed beds, Fujitsu aims to support companies and local governments in estimating carbon storage capacity, implementing conservation measures, cultivating new seaweed beds, and promoting biodiversity in seaweed reefs. This technology has significant potential to impact marine conservation efforts and contribute to broader environmental initiatives by providing valuable insights into ocean ecosystems’ health and productivity.

In summary, Fujitsu’s innovative approach using LiDAR and AI has tremendous potential for marine conservation efforts by providing accurate 3D data that can help protect coral reefs from climate change impacts such as ocean acidification and warming temperatures. With further development of this technology, it could also contribute significantly towards reducing carbon emissions by monitoring seaweed beds’ health status accurately.
