Currently, to map a coral reef, divers must take hundreds of photos from different angles. This creates a huge data processing challenge that often results in only small areas being mapped. DeepReefMap changes that.
Developed by EPFL researchers, DeepReefMap allows a single diver using a GoPro to map hundreds of meters of reef. The diver glides over the reef, continuously filming it. DeepReefMap’s deep learning algorithms then transform this video into a massive 3D composite that can be viewed from any angle captured on camera.
Unlike traditional methods that require bright, high-resolution images, DeepReefMap generally works well in dark and dim underwater environments. Moreover, it allows you to evaluate the condition of corals and classify species by their shape.
During field tests in the Red Sea, a diver captured a 100-meter section of the reef in just five minutes. After another five minutes, DeepReefMap processed the image and created a 3D map. You can use multiple GoPros mounted on the same frame to cover large areas. The Red Sea survey used six GoPro Hero 10 cameras and was all shot at 1080p/30fps; This is proof that DeepReefMap does not require high-end equipment.
