Abstract:
A method of calibrating a camera performs a first calibration for frames of a sequence captured by the camera to calculate for those frames first calibration data for a set of one or more camera parameters; performs, for selected frames of the sequence, a second calibration to calculate second calibration data for the selected frames in dependence on the first calibration data for those frames; and uses the second calibration data in the first calibration performed for subsequent frames of the sequence.

Claim (Index 14):
An apparatus as claimed in  claim 13 , wherein the calibration calculation unit is configured to determine the first calibration data for each of the said one or more frames of the sequence subsequent to the selected frame from: i) an estimate of the set of camera parameters determined from an incremental calibration; and ii) a correction determined from a comparison of the second calibration data for the selected frame and the first calibration data for that selected frame.
