## Overview

DynPose-100K is a large-scale dataset of diverse, dynamic videos with camera annotations. We curate 100K videos containing dynamic content while ensuring cameras can be accurately estimated (including intrinsics and poses), addressing two key challenges:
1. Identifying videos suitable for camera estimation
2. Improving camera estimation algorithms for dynamic videos

| Characteristic | Value |
| --- | --- |
| **Size** | 100K videos |
| **Resolution** | 1280×720 (720p) |
| **Annotation type** | Camera poses (world-to-camera), intrinsics |
| **Format** | MP4 (videos), PKL (camera data), JPG (frames) |
| **Frame rate** | 12 fps (extracted frames) |
| **Storage** | ~200 GB (videos) + ~400 GB (frames) + 0.7 GB (annotations) |
| **License** | NVIDIA License (for DynPose-100K) |

## DynPose-100K Download

DynPose-100K contains diverse Internet videos annotated with state-of-the-art camera pose estimation. Videos were selected from 3.2M candidates through advanced filtering.

### 1. Camera annotation download (0.7 GB)
```bash
git clone https://huggingface.co/datasets/nvidia/dynpose-100k
cd dynpose-100k
unzip dynpose_100k.zip
export DYNPOSE_100K_ROOT=$(pwd)/dynpose_100k
```

### 2. Video download (~200 GB for all videos at 720p)
```bash
git clone https://github.com/snap-research/Panda-70M.git
pip install -e Panda-70M/dataset_dataloading/video2dataset
```
- For experiments we use (1280, 720) video resolution rather than the default (640, 360). To download at this resolution (optional), modify [download size](https://github.com/snap-research/Panda-70M/blob/main/dataset_dataloading/video2dataset/video2dataset/configs/panda70m.yaml#L5) to 720
```bash
video2dataset --url_list="${DYNPOSE_100K_ROOT}/metadata.csv" --output_folder="${DYNPOSE_100K_ROOT}/video" \
              --url_col="url" --caption_col="caption" --clip_col="timestamp" \
              --save_additional_columns="[matching_score,desirable_filtering,shot_boundary_detection]" \
              --config="video2dataset/video2dataset/configs/panda70m.yaml"
```

### 3. Video frame extraction (~400 GB for 12 fps over all videos at 720p)
```bash
python scripts/extract_frames.py --input_video_dir ${DYNPOSE_100K_ROOT}/video \
    --output_frame_parent ${DYNPOSE_100K_ROOT}/frames-12fps \
    --url_list ${DYNPOSE_100K_ROOT}/metadata.csv \
    --uid_mapping ${DYNPOSE_100K_ROOT}/uid_mapping.csv
```

### 4. Camera pose visualization
Create a conda environment if you haven't done so:
```bash
conda env create -f environment.yml
conda activate dynpose-100k
```
Run the below under the `dynpose-100k` environment:
```bash
python scripts/visualize_pose.py --dset dynpose_100k --dset_parent ${DYNPOSE_100K_ROOT}
```

## LightSpeed Benchmark

LightSpeed contains ground truth camera pose and is used to validate DynPose-100K's pose annotation method.

Coming soon!

## FAQ

**Q: What coordinate system do the camera poses use?**  
A: Camera poses are world-to-camera and follow OpenCV "RDF" convention (same as COLMAP): X axis points to the right, the Y axis to the bottom, and the Z axis to the front as seen from the image.

**Q: How do I map between frame indices and camera poses?**  
A: The `frame_idxs` field in each camera PKL file contains the corresponding frame indices for the poses.

**Q: How can I contribute to this dataset?**  
A: Please contact the authors for collaboration opportunities.
