# The D2P dataset

The **D2P dataset** is a dataset based on the Depth2Pose monocular depth estimation benchmark, a pose-based evaluation of MDEs without ground-truth depth. The dataset contains challenging scenes beyond the distribution of common training data, together with a simple and extensible evaluation framework, presented on the github page. The scenes are divided into two categories: statues and vegetation. Undistorted images and reconstructions in standard colmap format is provided for each scene, together with a list of image pairs used for the evaluation.

## Dataset Fields

Each **scene** contains:
- `images/`: RGB images
- `sparse/`: COLMAP reconstruction files:
  - camera parameters
  - frames
  - image poses
  - 3D points
  - rigs
- `scene1_image_list.txt`: List of all images used for the benchmark, found in the images/ folder 
- `scene1_image_pairs.txt`: List of all image pairs used for the benchmark, for which realtive pose is evaluated

### Direct Use

Benchmarking monocular depth estimators. For the current leaderboard, see the [Depth2Pose webpage](https://kocurvik.github.io/depth2pose/)

### Load with 🤗 Datasets

```python
from datasets import load_dataset

ds = load_dataset("floodgab/d2p_dataset")
print(ds["validation"][0])
```

### Loading Example

To download the Depth2Pose dataset

```python
from huggingface_hub import snapshot_download

path = snapshot_download("floodgab/d2p_dataset")
```
