| # TowerDataset |
|
|
| TowerDataset is a power-line corridor point cloud dataset for semantic segmentation. |
| It contains annotated airborne/mobile LiDAR scenes of transmission towers, conductors, |
| insulators, vegetation, ground objects, and other corridor elements. |
|
|

|
|
| - Train: 419 scenes |
| - Validation: 122 scenes |
| - Test: 120 scenes |
| - Total: 661 scenes |
| - Total points: 2,466,076,987 |

| ## Data Format |
|
|
| All point clouds are stored as `.las` files. |
|
|
| - LAS version: 1.2 |
| - Point format: 2 |
| - Coordinate scale: 0.001 |
| - Point attributes: XYZ coordinates, RGB color, semantic label |
| - Semantic labels are stored in the LAS `classification` field |
