AN ADVANCED REDUCTION AND CALIBRATION FOR PHOTOGRAMMETRIC CAMERAS

Abstract

In order to fully exploit recent advances in photogrammetric technology it has been necessary to develop a comprehensive plate reduction appreciably more powerful than any hitherto employed. In addition to factors considered in previous plate reductions, an advanced reduction must treat with full physical and statistical rigour such factors as: random errors in catalogued stellar positions; atmospheric refraction (particularly at great zenith distances); higherorder symmetric radial distortion; tangential distortion and asymmetric radial distortion resulting from imperfectly centered optics; differential bias between measurements of different types of images; effective utilization of uncatalogued stars for photogrammetric control; introduction of a priori constraints on any of the parameters of the reduction. Such a reduction is developed in this paper and illustrations of its practical application are provided. Special attention is given to decentering distortion, a topic inadequately treated in the photogrammetric literature.
