Aerospace Instrument-Making Annotation << Back Estimation of vision system three-dimensional coordinates reconstruction accuracy S.A. Amelkin, V.V. Trushkov Particular properties of direct photogrammetric tasks approximate solving were considered. The stability of least squares method solving with possible appearance of disturbances of translation matrix factors was proven. Alternative task solutions suitable for practical use in vision systems were obtained. Emphasis is placed on various depending on the selected criterion estimations of coordinates reconstruction accuracy. Key words: technical vision system, model, three-dimensional coordinates, accuracy. E-mail: vmh48@mail.ru
