Dataset Description This dataset is designed for **Keypoint Detection (Pose Estimation)** tasks, specifically to detect the 4 semantic corners of a chessboard from various camera angles. It is intended to be used as **Phase 1** of a Chess Move Tracking pipeline. The detected keypoints are used to calculate the Homography matrix for Perspective Warping (straightening the board). - **Task:** Keypoint Detection (YOLO-Pose) - **Format:** YOLOv8 / YOLO11 Pose Format - **Input:** Raw video frames (rotated, tilted, occluded) - **Output:** 4 Keypoints (`a1`, `h1`, `a8`, `h8`) ## 2. Dataset Structure ### Keypoints Definition The model is trained to detect **1 Class (Chessboard)** with **4 Keypoints**: 1. **Index 0:** `a1` (Bottom-Left in White perspective) 2. **Index 1:** `h1` (Bottom-Right in White perspective) 3. **Index 2:** `a8` (Top-Left in White perspective) 4. **Index 3:** `h8` (Top-Right in White perspective) ### Data Splits | Split | Images | Description | | :--- | :--- | :--- | | **Train** | 3390 | Extracted from Various Chess Play Videos with augmentations | | **Valid** | 290 | Extracted from Various Chess Play Videos (Unseen angles) |
