Abstract: The use of reliable change detection from remote sensory data coming from Earth Observation (EO) technologies is one of the main challenges in security research. This paper describes the extraction of Digital Surface Models (DSM) from high resolution stereo imagery. It describes the algorithms used and the optimisations introduced to deal with man-made structures. The second part of the paper concentrates on the detection of changes from the different DSMs including the introduction of quality values for robust 3D change detection. Representative examples from real sites will be presented.
