Automated Orientation of Aerial Images

Methods for automated orientation of aerial images are presented. They are based on the use of templates, which are derived from existing databases, and area-based matching. The characteristics of available database information and the accuracy requirements for map compilation and orthoimage production are discussed on the example of Denmark. Details on the developed methods for interior and exterior orientation are described. Practical examples like the measurement of reseau images, updating of topographic databases and renewal of orthoimages are used to prove the feasibility of the developed methods.
