Abstract: In this paper a method for the forming of orthogonal additional parameters in a self-calibrating bundle block adjustment is described and the effect of each kind of systematic errors represented by Ebner's additional parameters on the adjusted results is analyzed.All these are deemed necessary for the understanding of the functional rule of systematic image errors as well as of the efficiency of the compensation of systematic errors by using the self-calibrating adjustment.These will help us also to analyze the possible strong correlations between the additional parameters and some other unknowns,to choose the additional parameters correctly and to know how to locate the ground control points more profitably.
