## 🔍 Troubleshooting



### 🐛 Common Issues



#### Installation Problems

```bash

# Missing OpenCV

pip install opencv-python opencv-contrib-python



# CUDA Issues (GPU acceleration)

pip install opencv-python-headless

export CUDA_VISIBLE_DEVICES=0

ulimit -m 8388608  # Increase memory limit

```



#### Performance Issues

```bash

# Low FPS

- Reduce image resolution

- Use ORB instead of SIFT/SURF

- Decrease max_features parameter

- Enable GPU acceleration



# High Memory Usage

- Reduce batch size

- Clear trajectory history periodically

- Use opencv-python-headless

- Monitor with htop/Task Manager

```
