Calibrate a camera and extract the intrinsic and distortion parameters.

Original script and more info can be found here.

1. Print out the checkerboard and attach it to a flat surface that doesn't distort the checkerboard.
2. Take images of the checkerboard with your camera from various angles and distances.
   • Save between 10 - 15 images (see examples below).
   • NOTE: In order for the calibration to be compatible with the rdk, take the images by running the camera using the rdk.
3. Run python3 cameraCalib.py YOUR_PICTURES_DIRECTORY
4. Copy-paste the intrinsic_parameters and distortion_parameters into your rdk config.
