Three-dimensional description of scenes observed in aerial photography

摘要

Three-dimensional (3-D) representation of natural scenes is a major problem of computer vision. In this paper, we present a method for re-building scenes from aerial photographs. The complete method involves the geometric modelling of taking of views, the automatic matching of images and the scene description as a set of vertical, oblique or horizontal planes. This method was tested on images of urban and industrial zones. The precision that we obtained allows us to introduce such a 3-D representation in a complex set of routines for the analysis of aerial photographs.
