Coordinate-Free Camera Calibration

A method for calibration of the optic center and the focal length of a pin-hole camera is suggested, where the camera parameters are constructed geometrically in the image plane. Box shaped objects of unknown dimensions,likefllrniture, buildings or a textured ground plane with trees, lamp poles or people are examples of sufficient calibration objects. Experiments are reported with relative errors in the range of one percent for suitable calibration views.
