A Method of Determining the Parameters of the Opticai System for the SBG Camera and the Results

In this article a method is proposed for determining the focal length, distortion coefficient and optical central position of the SBG camera. By the method we obtain that the focal length F=777.34 cm, the distortion value c=-1.48 × 10^-6mm. And the parameters and method for calculating the optical central position of photographic plates in the correction of the SBG photographic observations are also given here.
