Abstract

In this paper a new method for the georeferencing of low-oblique images is presented. Our georeferencing approach is based on the estimation of the camera pose and the subsequent use of geographical data in order to find global coordinates for every pixel in the image. For this purpose, concepts like Ground Control Point (GCP) or Digital Elevation Model (DEM) are explained and applied, achieving good results in real situations.
