| # OpenCommand |
|
|
| Catcher targets and pitcher command for MLB, inferred from broadcast video. |
|
|
| OpenCommand scores **command** using the pitch location's distance from target. |
|
|
| This dataset contains the 2025/2026 computer vision object detections, every intermediate the pipeline writes, and the resulting **command scores**. The pipeline itself and the full method write-up live at [github.com/tomdoyo/open-command](https://github.com/tomdoyo/open-command). |
|
|
| ## Download |
|
|
| ``` |
| hf download tomdoyo/open-command --repo-type dataset --local-dir data |
| ``` |
|
|
| That puts the tree where the pipeline expects it, so any stage re-runs from the code repo: |
|
|
| ``` |
| python src/solve_glove_locations.py 2026 |
| ``` |
|
|
| One file instead of the whole tree: |
|
|
| ``` |
| hf download tomdoyo/open-command 2026/command_scores.csv --repo-type dataset |
| ``` |
|
|
| ## Data |
|
|
| Each season lives under `<year>/`. |
|
|
| **Keys:** `(game_pk, play_id)` identify a pitch. |
|
|
| Raw detections (in `<year>/raw/`) are produced using YOLO11 glove/ball/strikezone detector models, with postprocessing based on detection confidence. |
|
|
| | File (per season) | One row per | Contents | |
| |---|---|---| |
| | `pbp_info.csv.gz` | pitch | Statcast 9-parameter trajectory, `sz_top`/`sz_bot`, plate location, pitcher, pitch type, and the game_date/type/venue | |
| | `raw/gloveball_tracks/<game_pk>.csv.gz` | frame | glove + ball detections (pixels on screen) | |
| | `raw/strikezone_tracking.csv.gz` | clip | broadcast strikezone detections (pixels on screen) | |
| | `camera_poses.csv.gz` | clip | camera pose (+ vote diagnostics & reprojection accuracies) | |
| | `glove_locations/<game_pk>.csv.gz` | detection | solved glove location (real-world) | |
| | `targets.csv.gz` | clip | naive/inferred targets | |
| | `command_scores.csv` | pitcher, pitch type | n, naive and inferred median miss | |
|
|
| `fg_pitching_2025.csv.gz` and `fg_pitching_2026.csv.gz` sit at the root, carrying the FanGraphs season lines command is validated against. |
