We propose an approach to constrain the reconstruction of complex surfaces to diierential information. Both linear structures such as crest lines or scalar elds such as curvature values can be used to generate a reconstruction of the surface which is consistent with the diierential properties. This method improves the accuracy of the reconstruction around the discontinuities and increases the c...

One problem of classical phase shifting for optical 3D surface reconstruction is the occurrence of ambiguities due to the use of fringe projection. We generally derive a number-theoretical approach to calculate absolute phase measurements which can be used as a base for a reliable surface reconstruction without any ambiguity. The essence of our method is the application of pattern sequences wit...

Themajority of the existing techniques for surface reconstruction and the closely related problem of normal estimation are deterministic. Their main advantages are the speed and, given a reasonably good initial input, the high quality of the reconstructed surfaces. Nevertheless, their deterministic nature may hinder them from effectively handling incomplete data with noise and outliers. In our ...

--Reconstruction of a 3-D object surface from sample of points has a wide range of applications such as computer-aided design (CAD) design, medical imaging,virtual reality and movie industry. The problem of approximating a surface from a given set of sample is known as surface reconstruction. This paper reviews the wellknown algorithms used to reconstruct the topology surface from sample points...

Three-dimensional models have played important roles in medical simulation and education. Surface models can be manipulated in real time and even online; surface models have significant features for an interactive simulation system. The objective surface models are obtainable from accumulation of each structure's outlines, followed by surface reconstruction. The aim of this research was to sugg...

It was recently found by us that oxygen induces ordered reconstructions on several III-Vsurfaces [1], which is significant, because ordered oxygen-induced reconstructions have not beenreported to III-V semiconductor surfaces having zincblende structure. These reconstructions attractattention due to the immense interest in the development of oxide-semiconductor interfaces for the...

This paper proposes a method for reconstructing a smooth and accurate 3D surface. Recent machine vision techniques can reconstruct accurate 3D points and normals of an object. The reconstructed point cloud is used for generating its 3D surface by surface reconstruction. The more accurate the point cloud, the more correct the surface becomes. For improving the surface, how to integrate existing ...

Reverse engineering technology plays an important role in reconstruction of a surface. It signicantly reduces the reconstruction time and the costs of the part duplication. This paper presents a new approach to the reconstruction of a surface. The proposed methodology nds the basic parts of the surface and blends surfaces between them. Each basic geometric part is divided into triangular patc...

Surface reconstruction is the process to achieve three-dimensional complex surface model quickly and accurately from three-dimensional data obtained as a sample, that is widely used in reverse engineering. Reverse engineering of geometric shapes is the process of converting a large number of measured data points into a concise and consistent computer representation. Reconstruction of a 3-D obje...
