-- Fx/Fy: Estimated camera focal length, in mm
+- Fx/Fy: Estimated camera focal length, in pixels
- Fx/Cy: Estimated camera optical center, in pixels. This should be at about the center of the image
- Distortion: OpenCV camera model distortion coefficients
- FOV: calculated using estimated focal length and image size. Useful for gut-checking calibration results
