Abstract

Camera calibration is fundamental for camera based measurement processes. While photogrammetric calibration models are widely established, the more sophisticated approach, describing an independent ray for every pixel, still requires thorough investigation to achieve its full potential. Such a Generic-Camera-Calibration or so called Vision-Ray-Calibration (VRC) compensates the effects of lens distortions more precisely than other techniques and can calibrate various lenses. Our current efforts are to improve calibration algorithms for VRC and find geometrically optimal calibration procedures. As a step towards this goal we present a metric to compare calibration results and therefore the necessary procedure to ensure that the coordinate systems of the calibrations are similar. With this new metric it is easier to investigate VRC procedures.
