Abstract
A method for highly accurate estimation of the geometry of photographing from space (the coordinates of the principal point and the camera orientation), with the use of ground reference points is proposed and experimentally tested. The method is based on the matching of projective and geographic coordinates of given landmarks on space photos and ground digital maps. A precise estimate of the camera geometry uses the singular value decomposition technique and the nonlinear root mean square method. The dependence of error in determining the absolute orientation angles on the number of points used for the calculation is obtained.
