|
|
| ## ✅ Test Completed Successfully |
|
|
| ### Input |
| - **Video**: `input_videos/video_1.mp4` (4.24 MB) |
| - **Duration**: 20 frames |
| - **Processing Time**: ~7 minutes (CPU only) |
|
|
| ### Output |
| - **File**: `output_videos/test_output.avi` (8.1 MB) |

|
|
| --- |
|
|
| ## 🔧 Issue Fixed |
|
|
| **Problem**: Import error for `BallAquisitionDetector` |
| - The class was in `ball_aquisition_detector.py` at root level |
| - Import expected it in `ball_aquisition/` module |
|
|
| **Solution**: |
| - Moved file to proper module directory |
| - Created `ball_aquisition/__init__.py` to export the class |
| - ✅ Import now works correctly |
|

|
| ## 🚀 How to Run Analysis |
|
|
| ### Option 1: Using the Convenience Script |
| ```bash |
| cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end |
| ./run.sh input_videos/video_1.mp4 |
| ``` |
|
|
| ### Option 2: Using Python Directly |
| ```bash |
| cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end |
| source venv/bin/activate |
| python main.py input_videos/video_1.mp4 --output_video output_videos/my_output.avi |
| ``` |
|
|
| ### Option 3: Using Test Script |
| ```bash |
| cd /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end |
| source venv/bin/activate |
| python test_system.py --video input_videos/video_1.mp4 |
| ``` |
|
|
| --- |
|
|
| ## 📁 Output Location |
|
|
| Analyzed videos are saved to: |
| ``` |
| /home/okidi6/Documents/Personalised-AI-Basketball-Skill-Analysis-System./back-end/output_videos/ |
| ``` |
|
|
| Current output: |
| - `test_output.avi` (8.1 MB) - ✅ Successfully created! |
|

|
|
| ## ⚡ Performance Notes |
|
|
| ### Processing Speed (CPU Only) |
| - **~1 second per frame** (979.7ms inference time) |
| - **20 frames processed** in ~7 minutes total |
| - Includes: detection, tracking, team assignment, analysis, and rendering |
|
|
| ### Stub Caching |
| The system created cached files in `stubs/`: |
| - `player_track_stubs.pkl` (56 KB) - Player detections |
| - `ball_track_stubs.pkl` (2.8 KB) - Ball detections |
| - `court_key_points_stub.pkl` (63 KB) - Court keypoints |
|
|
| **Benefit**: Next run on same video will be much faster! |
|

|
| ## 🎥 View Your Results |
|
|
| To view the analyzed video: |
|
|
| ```bash |
| # Using default video player |
| xdg-open output_videos/test_output.avi |
| |
| # Or using VLC |
| vlc output_videos/test_output.avi |
| |
| # Or using mpv |
| mpv output_videos/test_output.avi |
| ``` |
|
|
| The video includes: |
| - Player bounding boxes (color-coded by team) |
| - Ball tracking visualization |
| - Court keypoint overlays |
| - Team ball control statistics |
| - Pass and interception markers |
| - Tactical view (mini-map) |
| - Player speed and distance metrics |
| - Frame numbers |
|

|
|
| ## 🎯 Next Steps |
|
|
| ### 1. Test with More Videos |
| ```bash |
| # Test with other sample videos |
| python main.py input_videos/video_2.mp4 |
| python main.py input_videos/video_3.mp4 |
| python main.py input_videos/video_4.mp4 |
| ``` |
|
|
| ### 2. Add Your Own Videos |
| - Place basketball videos in `input_videos/` |
| - Recommended: 10-30 second clips for testing |
| - Supported formats: MP4, AVI |
|
|
| ### 3. Optimize Performance |
| - Consider installing CUDA-enabled PyTorch for GPU acceleration |
| - Current: ~1 second per frame (CPU) |
| - With GPU: Could be 5-10x faster |
|
|
| ### 4. Integration |
| Once satisfied with results: |
| - Integrate with FastAPI backend |
| - Add video upload endpoints |
| - Implement async processing |
| - Store results in Supabase |
| - Connect to frontend |
