Abstract :
This Paper discusses the practical implementation of a polynomial camera model for a wide variety of common cameras equipped with catadioptric, fish-eye, short or long focal length lenses. A unified approach of deriving initial model parameters using an extended direct linear transformation followed by a maximum likelihood estimation of these parameters was tested with different camera systems. The possibility of sub-pixel accuracy for all used camera systems will be shown.
