3D Modelling Using Geometric Constraints: A Parallelepiped Based Approach

In this paper, efficient and generic tools for calibration and 3D reconstruction are presented. These tools exploit geometric constraints frequently present in man-made environments and allow camera calibration as well as scene structure to be estimated with a small amount of user interactions and little a priori knowledge. The proposed approach is based on primitives that naturally characteriz...

Towards a 3D Spatial Urban Energy Modelling Approach

Today’s needs to reduce the environmental impact of energy use impose dramatic changes for energy infrastructure and existing demand patterns (e.g. buildings) corresponding to their specific context. In addition, future energy systems are expected to integrate a considerable share of fluctuating power sources and equally a high share of distributed generation of electricity. Energy system model...

Spatial Modelling with Geometric Constraints

In recent years constraint-based modelling has become an important method for describing dependencies within a CAD-model. In this paper, we present a constraint-based approach for the assembly, the spatial joining of separate rigid bodies. It is mainly in-uenced by Kramer's rule-based state automaton, which is an appropriate concept for solving the geometric constraint solving problem (GCSP) ee...

3d Geometric Modelling of Ikonos Geo Images

Digital elevation model (DEM) extracted from IKONOS along-track stereo images with photogrammetric method is evaluated. As few as 12 GCPs are enough for the stereo photogrammetric bundle adjustment, which also filters the errors of the input data. With an area-based image matching users may produce high resolution DEMs with LE68 errors of 1 m to 4 m depending on the land covers. The best result...

3D Modelling From Images Using Geometric Constraints

Image-based 3D modelling is often an underconstrained and noise-sensitive process. Incorporation of geometrical constraints increases the robustness of this process, especially when dealing with small image sets. This relies on a human operator and his intuitive knowledge of the main properties of the objects commonly present in scenes. In this thesis we propose various approaches for the camer...
