Coral reefs 3D photogrammetry

Description

We 3D mapped multiple coral reefs in Indonesia (following this protocol) and sharing all our data with you 🤗

This dataset currently contains 90,289 (352GB) of raw GoPro images and some colour-corrected images.

Additional data - including camera poses, reconstructed 3D point clouds, 3D polygonal meshes, orthomosaics, annotations, and 3D Gaussian Splatting models - will be added soon. We just decided share raw data right now, and processed as soon we have it, so we don't block the progress.

There's one survey site (farm) has a lot of photos with a ton of coral reef nurseries. It was collected not for reconstruction, but rather for training species classification models, because each table has the same coral species.

Everything (except the farm) is correctly georeferenced and scaled.

We hope this dataset helps improve AI models for coral reef species classification, 3D semantic segmentation, 3D reconstruction, disease detection and help protect these precious ecosystems! 🪸
