Dependencies

• Python 3.5
• NumPy
• OpenCV
• Matplotlib
• MoviePy

How to run

To run the script stand-alone:

Usage: lane_lines.py [options]

Options:
  -h, --help            show this help message and exit
  -i INPUT_FILE, --input_file=INPUT_FILE
                        Input video/image file
  -o OUTPUT_FILE, --output_file=OUTPUT_FILE
                        Output (destination) video/image file
  -I, --image_only      Annotate image (defaults to annotating video)

For example, to detect lanes lines on the video 'challenge.mp4', run:

python lane_lines.py -i challenge.mp4 -o extra.mp4

To detect lane lines on a single image (e.g. for debugging), run:

python lane_lines.py -i input_image.jpg -o output_image.jpg -I
