Because we combine 2-D edge information, photometric and chromatic attributes and 3-D information, we can deal with complex houses. Neither do we assume the roofs to be flat or rectilinear nor do we require parameterized building models. From only one image, 2-D edges and their corresponding attributes and relations are extracted. Using a segment stereo matching based on all available images, the 3-D location of these edges are computed. The 3-D segments are then grouped into planes and 2-D enclosures are extracted, thereby allowing to infer adjoining 3-D patches describing roofs of houses. To achieve this, we have developed a hierarchical procedure that effectively pools the information while keeping the combinatorics under control. Of particular importance is the tight coupling of 2-D and 3-D analysis. * We acknowledge the support given to this research by ETH under project 13-1993-4.

This measure contains not only geometric and topographic information, but also differential information covering land or atmospheric changes between the two scenes observed. These atmospheric artifacts can be an obstacle to the production of digital terrain models (DTMs) from multi-pass SAR interferometry.

Several methods have been proposed to reconstruct houses from aerial images, most of them using rather specific models. These methods can not be applied when dealing with european-style houses and when a high level of detail is required. We present a system that works with rules instead of parameterizable shape models. This allows a larger variability of the objects to be extracted but also results in a more complex structure of the knowledge base and in a more sophisticated reasoning control. In the application section we demonstrate the use of such a system for reconstructing an object made up of planar surfaces from an aerial image. We will also explain how additional domain specific knowledge could speed up the extraction process and increase robustness. 1 Introduction The development of practical algorithms that support the robust and precise reconstruction of buildings and other man-made objects from aerial imagery is one of the aims of the project AMOBE 1 , a join...

We present a technique to extract complex suburban roofs from sets of aerial images. Because we combine 2-D edge information, photometric and chromatic attributes and 3-D information, we can deal with complex houses. Neither do we assume the roofs to be at or recti-linear nor do we require parameterized building models. From only one image, 2-D edges and their corresponding attributes and relations are extracted. Using a segment stereo matching based on all available im-ages, the 3-D location of these edges are computed. The 3-D segments are then grouped into planes and 2-D enclosures are extracted, thereby allowing to infer adjoining 3-D patches describing roofs of houses. To achieve this, we have developed a hierarchical procedure that eectively pools the information while keeping the combinatorics under control. Of particular importance is the tight coupling of 2-D and 3-D analysis. 1

Automation of Digital Terrain Model Generation and Man-Made Object Extraction from Aerial Images ... more Automation of Digital Terrain Model Generation and Man-Made Object Extraction from Aerial Images (AMOBE) is a joint project between the Institute of Geodesy and Photogrammetry (IGP) and the Institute of Communications Technology (Image Science Group) (IKT) at the Swiss Federal Institute of Technology in Zurich. In the project we develop methods and algorithms to detect and reconstruct man-made objects, such as buildings and roads, and to generate Digital Surface Models (DSMs) from high resolution aerial images. Primary attention in AMOBE focuses on high quality reconstruction of buildings as being one of the more predominantly and frequently occurring 3-D man-made objects in high-resolution aerial imagery. In this paper we present our research strategy, current results, and make an outlook onto future work.

Such applications will cover classic mapping applications, advanced building information management, risk and disaster management and simulations. Exotic applications such as virtual reality and 3D printing will also be studied and the benefit for such applications will also be shown which is extending the classic mapping usage to more streamlined applications. 1.

The introduction of such product has changed the way how people are interacting with 3D information and using that 3D information into their geographic system and organization. This paper will focus on the advantages of automated processing for 3D mosaic generation with some real case applications of such final product. Indeed, introducing automatic processing for such database has changed the current paradigm that 3D realistic database can only be acquired and generated with lots of manual work and taking months to get small area. Introducing fast automatic processing gives ability to map a whole city in few weeks and then to make available such data with very dense 3D details to numerous actors which can then integrate it into their application. It opens also real possibili...

Such software should be able to handle large volume of digital data, to distribute the computation over multiple computers and to produce automatically accurate end-products. If these constraints can be met, it is then possible to produce cartographic products instantly over large areas: digital data is uploaded in a PIXEL FACTORY and accurate end-products are automatically produced by this factory. Within the paper, a description of such a framework will be presented and compared to classical photogrammetric systems.
