SOLUTIONS FOR EXTERIOR ORIENTATION IN PHOTOGRAMMETRY, A REVIEW

Résumé

The determination of the attitude, the position and the intrinsic geometric characteristics of the camera is known as the fundamental photogrammetric problem. It can be summarised in the determination of camera interior and exterior orientation parameters, as well as the determination of 3D coordinates of object points. The term "exterior orientation" of an image refers to its position and orientation related to an exterior coordinate system. Several methods can be applied to determine the parameters of the orientation of one, two or more photos. The orientation can be processed in steps (as relative and absolute orientation) but simultaneous methods (as bundle adjustments) are now available in a majority of software packages. Several methods have also been developed for the orientation of single images. They are based in general on geometric and topologic characteristics of imaged objects. In this paper we present a survey of classical and modern methods for the determination of the exterior parameters in photogrammetry, available for some of them as software packages with practical examples on the Internet. The presented methods are classified in three principal groups. In the first one, a selection of approximate methods for applications that do not require grand accuracy are presented. They are also used to calculate values required for iterative methods. In the second group, standard point-based methods derived from collinearity, coplanarity or coangularity conditions are shortly reviewed with an extend to line-based approaches. The third group represents orientation methods based on constraints and projective geometry concepts, which are more and more of interest for photogrammetrists. In the last section, the paper gives a summary of existing strategies for automatic exterior orientation in aerial photogrammetry.
