| # PVL-BA-Bench |
|
|
| PVL-BA-Bench is a large-scale bundle adjustment benchmark dataset from Polar-vision Lab. It provides public release metadata, interactive browser viewers, and downloadable PVL-BA, COLMAP, and BAL packages for photogrammetric optimization research. |
|
|
| ## Release Links |
|
|
| - Static release index and interactive viewers: <https://pub-2c28bdf6e62548919c47727a9b969dda.r2.dev/index.html> |
| - Downloadable packages in this dataset repository: `packages/{pvl-ba,colmap,bal}/.../*.zip` |
| - Source tools and manifests: <https://github.com/Polar-vision/PVL-BA-Bench> |
|
|
| ## Dataset Viewer |
|
|
| The Hugging Face Dataset Viewer exposes three tabular metadata configurations: |
|
|
| - `datasets`: one row per released BA problem. |
| - `artifacts`: one row per downloadable package, including relative package path, size, file count, and SHA-256 checksum. |
| - `viewers`: one row per interactive viewer HTML file. |
|
|
| The large ZIP packages are intentionally not used as Viewer data files. They are downloadable artifacts referenced by the metadata tables. |
|
|

|
|
