1. A method for assessing a camera calibration,
ascertaining a first quality measure;
assessing a systematic error using the first quality measure, the assessment being carried out with respect to errors remaining after a calibration;
virtually segmenting an overall calibration object including at least one calibration object into calibration objects;
estimating a detector noise for each of the calibration objects;
combining the detector noise for each of the calibration objects to form an overall estimate; and
comparing the combined detector noise with an estimate of detector noise of the overall calibration object.
