Registration of Digitized Aerial Photography with a Digital Map Data Base.
Abstract
This report investigates the feasibility of automatic registration of a digital aerial image with an existing map data bank. The geometry of an aerial image can be modelled mathematically by a central perspective. The theoretical part presents the background of this model and discusses various strategies to solve the problem of resection in space. We propose a method to automatically recognize areal features of the map in the image and to extract control points for the reconstruction of the imaging configuration. Recognition is done by three algorithms: by correlation, by thresholding and by adaption of a binary mask. Results give estimates for the distance of projected features from actual objects, dislocations caused by variation of the transformation parameters and include experiments performed with an actual aerial photograph.
