# Coral reefs 3D photogrammetry

## Description

We 3D mapped multiple coral reefs in Indonesia (following this [protocol](https://wildflow.ai/protocol)) and sharing all our data with you 🤗

![exampel image](https://huggingface.co/datasets/wildflow/corals/resolve/main/indonesia_tabuhan_p1_20250210/corrected/images/GPAA0485.jpg)

This dataset currently [**contains 89,407 (350GB) of raw GoPro images**](https://huggingface.co/datasets/wildflow/sweet-corals/tree/main) and some [colour-corrected](https://huggingface.co/datasets/wildflow/sweet-corals/tree/main/indonesia_tabuhan_p1_20250210/corrected/images) 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 hope this helps improve AI models for coral reef species classification, 3D semantic segmentation, 3D reconstruction, disease detection and help protect these precious ecosystems!
