Abstract

Numerical Relative Orientation using elements of one projector (dependent orientation) has been applied to several cases of complete as well as incomplete stereoscopic models of flat terrain. Parallax observations were made on the Zeiss Jena Stereometrograph E. using the (by) screw. Since in all cases more than five observations were available, a least squares solution was used to solve for the five elements of relative orientation. This allowed the accuracy assessment to be based on analysis of variances and covariances. In complete models, the accuracy of the solution improved by increasing the number of the orientation points. However, some elements improved more significantly than others. For incomplete models, the distribution of the orientation points proved to be more significant than their number. The larger the determinant of the coefficient matrix of normal equations, the better was the solution. 111-conditioned systems resulted in large variances despite an increased number of orientation points.
