# Golf Ball Trajectory Tracker
This application uses Meta's Segment Anything Model (SAM) 2.1 and physics-based trajectory fitting to track and analyze golf ball trajectories from videos.
## Setup
1. Download the SAM model checkpoint:
- Visit: https://dl.fbaipublicfiles.com/segment_anything/sam_vit_b_01ec64.pth
- Save the file in the project directory
2. Install dependencies:
```bash
pip install -r requirements.txt
```
## Usage
1. Run the application:
```bash
python app.py
```
2. Using the interface:
- Upload a golf swing video
- Click "Process Video" to load the video
- Click on the golf ball position in key frames (at least 3 points recommended)
- The application will fit and display the trajectory
- Use "Clear Points" to start over
## Features
- Interactive point selection for trajectory tracking
- Physics-based trajectory fitting
- Real-time visualization of predicted path
- CPU-optimized for Intel UHD 630 graphics
## Notes
- The application uses the SAM base model optimized for CPU usage
- For best results, provide clear video footage with visible golf ball
- Select points at different stages of the ball's flight for better trajectory fitting
