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

Fujitsu is using LiDAR and artificial intelligence (AI) to create a digital twin of seaweed beds, which supports marine conservation efforts and contributes to carbon neutrality initiatives and biodiversity. The technology for creating a digital twin is based on a real-time measurement technique that Fujitsu originally developed for its Evaluation Support System, working with the International Gymnasts Federation and using LiDAR technology.

This technology scans seaweed beds from autonomous underwater vehicles, even under challenging conditions like currents and waves. Artificial intelligence is then used to restore color and contour to underwater subjects, creating high-resolution 3D images. This allows for the precise identification and measurement of targets up to several centimeters, even in murky waters.

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. They were able to obtain precise 3D data to map coral reefs. In the future, Fujitsu plans to expand the use of this technology to map seaweed beds, which play a crucial role in absorbing carbon.

By creating a digital twin of seaweed beds, Fujitsu aims to support companies and local governments in estimating 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.
