Registration of Digitized Aerial Photography with a Digital Map Data Base

Franz Leberl, Hubert Ranzinger

Publikation: Buch/Bericht/KonferenzbandBuch (Autorenwerk)


The feasibility of automatic registration of a digital aerial image with existing map data bank is investigated. The geometry of an aerial image can be modelled mathematically by a central perspective. The background of this model and various strategies to solve the problem of resection in space are discussed. A method to recognize automatically areal features of the map in the image and to extract control points for the reconstruction of the imaging configuration is proposed. Recognition is done by three algorithms; by correlation, by thresholding and by adaption of a binary mask. Estimates for the distance of projected features from actual objects and dislocations caused by variation of the transformation parameters are given.
