3. Script Descriptions: A_formatIntrinsics

• A_formatIntrinsics

  • Description:

  This function initializes the intrinsics matrix for a given camera. It is to be run first in the progression. It should be run for each camera in a multi-camera fixed station, every time the focus is adjusted, a new lens is added, or a new enclosure is introduced. For a UAS camera, it should be run for each type of recording mode (4K Video, 12MP snapshot, etc). It can entered manually or refer to a Cal-Tech Camera Calibration file, a third-party MATLAB repository to perform camera intrinsic calculations [3]. Note, this function assumes the calib_results is for a standard distortion model, not fish eye. Model is outlined in Section 5.

  • Input:

  Input is entered by user into the script in Section 1, 2, and possibly 3.

  Section 1: Loading and Saving Information

  Variable	Description
  oname	Output string for the basename for the intrinsic matfile to be saved under.
  odir	Output filepath where the intrinsic mat file will be saved.

  Section 2: Intrinsics

  Variable	Description
  iopath	Filepath of the saved Caltech calibration results (Calib_result.mat). If user is going to enter manually, this should be left empty {} and entered in Section 3.

  Section 3: Manually Entered Intrinsics (Optional)

  Variable	Description
  intrinsics	A [1x11] vector describing the focal lengths and distortion of the camera/lens combination. Distortion coefficients are defined by [3] and defined in Section 5.

  • Output:

  A .mat file saved as oname_IO.mat in odir. Will contain following variables.

  Variable	Description
  intrinsics	A [1x11] vector describing the focal lengths and distortion of the camera/lens combination. Distortion coefficients are defined by [3] and defined in Section 5.
