| # MultiCameraDataset |
|
|
| A trimmed copy of the **CHIRLA** dataset, kept for building a multi-target multi-camera (MTMC) |
| person tracking pipeline from scratch: raw videos plus full per-frame identity annotations. |
| The Re-ID / tracking benchmark crops and their Parquet manifests from the original release were removed. |
|
|
| **Original dataset:** [bdager/CHIRLA](https://huggingface.co/datasets/bdager/CHIRLA) · |
| [Paper](https://www.nature.com/articles/s41597-025-06425-3) · [Code](https://github.com/bdager/CHIRLA) · |
| [Project page](https://bdager.github.io/CHIRLA/). All credit for data collection and annotation goes to the |
| CHIRLA authors. Redistributed under **CC BY 4.0**; the only modifications are the removal of files and |
| renaming of `:` to `-` in file names (Windows compatibility). |

|
| ## Contents |
|
|
| | Path | Description | |
| |------|-------------| |
| | `videos/seq_XXX/camera_N_<timestamp>.avi` | 70 videos (10 sequences × 7 cameras), 1080×720, 30 fps | |
| | `videos/metadata.parquet` | file_name, annotation_path, camera, seq | |
| | `annotations/seq_XXX/camera_N_<timestamp>.json` | Per-frame boxes: `{"<frame>": [{"id": int, "BboxP": [x1,y1,x2,y2]}]}` | |
| | `data/videos_{train,test}_all.parquet` | Official video-level split (train = seq_004, seq_026) | |
| | `filename_mapping.csv` | Original path (with `:`) ↔ path in this repo (with `-`) | |
| | `docs/` | Floor plan with camera positions and a sample view per camera | |
|
|
| Notes: |
| - Frame keys in annotations start at **1**. |
| - Person IDs are consistent across all cameras and all sequences (21 positive IDs). |
| - Paths inside the Parquet files still contain `:`; apply `path.replace(':', '-')` before opening. |
| - Cameras share a start timestamp per sequence, but frame counts differ by up to ~60 frames (~2 s). |
| - Camera views barely overlap; there is no calibration or ground-plane homography. |
