3d Building Adjustment Using Planar Half-space Regularities
The automatic reconstruction of 3D building models with complex roof shapes is still an active area of research. In this paper we present a novel approach for local and global regularization rules that integrate building knowledge to improve both the shape of the reconstructed building models and their accuracy. These rules are defined for the planar half-space representation of our models and ...
متن کامل3d Building Generalization Based on Half-space Modeling
This article presents a novel approach for the automatic generalization of 3D building models with regard to a cartographic 3D visualization. Here, the goal is not to render realistic, but rather visually appealing images of an urban scene. The geometric simplification is realized by remodeling the object by means of a process similar to half space modeling. Approximating planes are determined ...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولGeneralization of 3d Building Data Based on Scale-spaces
For an interactive visualization of three dimensional (3D) city models a Level of Detail representation is extremely useful to avoid unnecessary computations. Differently detailed models of the same object are displayed depending on the distance of the object. This implies that less detailed models have to be generated from complex models (generalization). In this paper an approach for the auto...
متن کاملShear Waves Through Non Planar Interface Between Anisotropic Inhomogeneous and Visco-Elastic Half-Spaces
A problem of reflection and transmission of a plane shear wave incident at a corrugated interface between transversely isotropic inhomogeneous and visco-elastic half-spaces is investigated. Applying appropriate boundary conditions and using Rayleigh’s method of approximation expressions for reflection and transmission coefficients are obtained for the first and second order approximation of the...
