DETERMINATION OF A SCALE FACTOR IN PHOTOGRAMMETRY

The work aims to improve determination of space coordinates of image points. The research presents analysis of the formulas, used to determine space coordinates of image points, which are obtained with corrections in a space ratio, fixing such mutual orientation of the basis of image pair projecting, which exists during surveying and does not depend on deviations in determination of a scale ratio. The authors make conclusions that formulas for determination of a space ratio are not precise. It can be explained by the fact, that distance between the centers of surveying are defined in plane, i.e. distance between the points, which characterize centers of surveying, is projected on one of the plane (X, Y or Z). The work proposes original formulas, which determine distance between the centers of surveying in space, but not on projections on planes.
