ABSTRACT
We present an optimized full scale automatic camera
calibration approach which is both accurate and simple to
implement. The method can be applied to a wide range of
cameras equipped with normal, wide-angle, fish-eye, and
telephoto lenses. The procedure does not require prior
knowledge of any parameters. The method uses a simple
planar calibration pattern which is observed from different
positions. Closed-form estimates for the intrinsic and
extrinsic parameters are computed followed by nonlinear
optimization. A polynomial function describes the lens
projection instead of the commonly used radial model.
Statistical information criteria are used to automatically
determine the complexity of the lens distortion model. The
proposed complete calibration method is shown to obtain
