Abstract

An accurate method based on the automatic identification of starmap is put forward in this paper to calibrate optical systems.The basic procedure is to obtain the star's coordinates in image space by processing starmap and calculating the centroid of a star

accurately calculate the star's apparent position

correct the atmospheric refraction

and obtain the the star's coordinates in object space by automatic celestial body identifying techniques

then calculate the lens aberration and the internal and external parameters of an optical system.
