Unwrapping of Urban Surface Models
ثبت نشده
چکیده
In this paper we present an approach for the geometric reconstruction of urban areas. It is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate the type and parameter of basic primitives which in turn are combined to obtain complex building structures. The final output consists of 3D CAD models for the buildings. Using the reconstructed geometry, terrestrial images can be mapped onto building facades to generate virtual city models.

InSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space
Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...

Phase unwrapping in L-dimensional topologies is an important problem that has several applications in radar and satellite imaging. Sum product algorithm (belief propagation) gives excellent results for the phase unwrapping problem. In this work, we present a gradient smoothing technique that uses higher order surface models to produce very smooth surfaces and report an improvement in the soluti...

PU (phase unwrapping) is the key step and important problem in DEM (digital elevation model) extraction and the measurement of surface deformation of InSAR (Interferometric synthetic aperture radar). The CKFPUA (conventional Kalman filter phase unwrapping algorithm) can obtain reliable results in the flat terrain areas, but it caused error transmission not making the accurate inversion of surfa...
متن کاملEvaluation of urban resilience in dealing with flood risk using SWMM and Hec-Ras models in Mashhad Ab-o-Bargh neighborhood
Aims & Background Assessing the vulnerability of urban areas to surface water in cities is of particular importance. Destruction of the watershed upstream of urban areas, including the destruction of vegetation and road construction, as well as the uncontrolled expansion of urban and industrial lands, reduces the infiltration and increases runoff and carries the risk of floods. This study aims ...
متن کاملRevisiting Homomorphic Wavelet Estimation and Phase Unwrapping
Surface-consistent deconvolution is a standard processing technique in land data to uniformize the wavelet across all sources and receivers. The required wavelet estimation step is generally done in the homomorphic domain since this is a convenient way to separate the phase and the amplitude spectrum in a linear fashion. Unfortunately all surface-consistent deconvolutions make a minimum-phase a...
