# Coral reefs 3D photogrammetry

## Description

We 3D mapped multiple coral reefs in Indonesia following [wildflow.ai/protocol](https://wildflow.ai/protocol) using two GoPro cameras.

This dataset currently contains raw and color-corrected photos. Additional data - including camera poses, reconstructed 3D point clouds, 3D polygonal meshes, orthomosaic, annotations, and 3D Gaussian Splatting models - will be added soon.
