Analytical Aspects of Small Format Surveys Using Oblique Aerial Photographs

Abstract

Appropriate analytical techniques to make use of small format oblique photographs for photogrammetry are outlined, including several transformation methods and associated problems relating to the inclusion of reseau measurements. Various options are compared by applying the techniques to a series of hand-held, small format oblique aerial photographs.

The accuracies of derived coordinates are examined and show that the small format camera can be considered to be of photogrammetric importance. Some of the transformation methods associated with the use of reseau photography to correct for image deformation are outlined and compared in terms of their ability to model specific problems associated with semi-metric photography.
