Uncalibrated reconstruction of curved surfaces
Image and Vision Computing, 1999In this article, we show that even if the camera is uncalibrated and its translational motion is unknown, curved surfaces can be reconstructed from their apparent contours up to a 3D affine ambiguity. Further, we show that even if the reconstruction is non-metric (non-Euclidean), we can still extract useful information from the reconstruction for many ...

Parallel Surface Reconstruction
2002The task of surface reconstruction is to find a mathematical representation of a surface which is given only by a set of discrete sampling points. The mathematical description in the computer allows to save or transfer the geometric data via internet, to manipulate (e.g.

Surface Reconstruction - An Introduction
Scientific Visualization Conference (dagstuhl '97), 1997The goal of surface reconstruction is to find a surface from a given finite set of geometric sample values. In many applications, the sample values are points. But other types of samples, like curves occurring e.g. in tactile sampling by an adapted milling machine, or volume densities occurring for instance in X-ray based computer tomography, are also ...

Variational surface reconstruction
2016The demand for capturing 3D models of real world objects or scenes has steadily increased in the past. Today, there are numerous developments that indicate an even greater importance in the future: Computer generated special effects are extensively used and highly benefit from such data, 3D printing is starting to become more affordable, and the ...

Surface reconstruction and surface magnetism
Journal of Magnetism and Magnetic Materials, 1992Abstract Surface lattice relaxation including changes of interlayer spacings and reconstruction is theoretically investigated in magnetic transition metal thin films with a nearly half-filled d band. The c(2 × 2) surface reconstruction with 〈001〉 atomic displacement is found in bcc(001) films with surface-induced antiferromagnetism.

Numerical reconstruction of optical surfaces
Journal of the Optical Society of America A, 2008There are several problems in optics that involve the reconstruction of surfaces such as wavefronts, reflectors, and lenses. The reconstruction problem often leads to a system of first-order differential equations for the unknown surface. We compare several numerical methods for integrating differential equations of this kind.

Reconstruction of the Si(113) surface
Physical Review B, 1996The tight-binding molecular dynamics method is used to study reconstructions of the Si(113) surface. Comparisons of tight-binding total energies of the 3\ifmmode\times\else\texttimes\fi{}1 and 3\ifmmode\times\else\texttimes\fi{}2 reconstructed surfaces as well as the bulk terminated and the fully relaxed 1\ifmmode\times\else\texttimes\fi{}1 surfaces ...

Reconstruction of the Pt(111) surface
Physical Review Letters, 1992The structure of the clean Pt(111) surface has been studied between 300 K and 0.92${\mathit{T}}_{\mathit{m}}$ (${\mathit{T}}_{\mathit{m}}$=2045 K) via x-ray scattering. The surface is unreconstructed for temperatures less than 0.65${\mathit{T}}_{\mathit{m}}$, but reconstructs at higher temperatures to form a layer isotropically compressed and ...
