Fixed camera calibration type

The Fixed camera calibration type uses fixed locations of the cameras and the reference markers to calibrate a camera system. It can be used for systems covering large areas, where other methods are impractical. The fixed calibration type requires that the cameras are at fixed, stable locations.

The fixed camera calibration requires that the exact positions of the cameras and reference markers, obtained from a survey measurement, are entered on the Calibration page in the Project options dialog, see chapter Fixed camera calibration. The fixed calibration than calculates the camera orientations and optimizes the focal lengths for each camera, based on the measured positions of the reference markers.
