📦 Overview

This repository hosts the datasets and pretrained .ply Gaussian models for PanoLOG / GGPS — panoramic (equirectangular / ERP) outdoor 3D Gaussian Splatting reconstruction. For training and rendering code, see the GGPS code repository.

datasets/ — per-scene capture data (ERP panoramas + openMVG reconstruction), one archive per scene.
ply/ — pretrained / reconstructed Gaussian Splatting .ply models.

🔢 Dataset overview

Scene	Archive	Panoramas	Reconstruction
FTP	`datasets/FTP.zip`	354	openMVG (`sfm_data.bin`/`.json`, `colorized.ply`, `cloud_and_poses.ply`)
NSC	`datasets/NSC.zip`	1862	openMVG (same as above)
NSK	`datasets/NSK.zip`	576	openMVG (same as above)
Total		2792

All panoramas are equirectangular (ERP) .png.

Each dataset archive expands to the openMVG → COLMAP layout expected by the code repo:

<scene>/
├── images/                  # ERP panoramas
└── reconstruction/
    ├── sfm_data.bin         # openMVG binary (sfm_data.json can be re-exported from this)
    ├── sfm_data.json        # openMVG JSON
    ├── colorized.ply        # colorized sparse point cloud (3DGS init)
    └── cloud_and_poses.ply
