Abstract

Although vertical aerial images have played the leading role in photogrammetric applications for more than a century, in recent years oblique aerial images have gained popularity, mainly because of certain fundamental advantages they provide compared to nadir views, in combination with the progress made in photogrammetric and computer vision algorithms that enable their automatic processing. The main subject of this dissertation is the metric exploitation of datasets containing oblique aerial images, with emphasis on the establishment of automatic georeferencing algorithms, both in terms of exterior orientation estimation and in terms of image-to-ground 2D transformation, i.e., polynomial/projective transformation that approximates the relationship between each image and the ground reference system. Furthermore, it investigates how the automatic extraction of elements describing the geometry of the scene depicted in oblique aerial images contributes in their metric exploitation, foc...
