Surface Reconstruction from Points
نویسنده
چکیده
This report surveys recent techniques for reconstructing surfaces from points. We describe four main ideas in the graphics literature: signed distance estimation, Voronoi-based reconstruction, implicit surface fitting, and moving least squares surfaces. The main challenges include reconstruction without surface normals, robustness to noise, accuracy to sharp features, and provable reconstruction guarantees. We compare various techniques and discuss possible avenues for future work.

3D Reconstruction Using Cubic Bezier Spline Curves and Active Contours (Case Study)
Introduction 3D reconstruction of an object from its 2D cross-sections (slices) has many applications in different fields of sciences such as medical physics and biomedical engineering. In order to perform 3D reconstruction, at first, desired boundaries at each slice are detected and then using a correspondence between points of successive slices surface of desired object is reconstructed. Mate...
متن کاملA Survey on Surface Reconstruction Algorithms for 3-D Unorganized points
--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...
متن کاملDirect Reconstruction of Displaced Subdivision Surface from Unorganized Points
In this paper we propose a new mesh reconstruction algorithm that produces a displaced subdivision mesh directly from unorganized points. The displaced subdivision surface is a new mesh representation that defines a detailed mesh with a displacement map over a smooth domain surface. This mesh representation has several benefits — compact mesh size, piecewise regular connectivity — to overcome l...
متن کاملDirect Shape Carving: Smooth 3D Points and Normals for Surface Reconstruction
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 ...
متن کاملThe displaced subdivision surface reconstruction from unorganized points
In this paper we propose a new mesh reconstruction scheme that produces a displaced subdivision surface directly from unorganized points. The displaced subdivision surface is a new mesh representation that defines a detailed mesh with a displacement map over a smooth domain surface, but original displaced subdivision surface algorithm needs an explicit polygonal mesh since it is not a mesh reco...
متن کاملShape-aware surface reconstruction from sparse 3D point-clouds
The reconstruction of an object's shape or surface from a set of 3D points plays an important role in medical image analysis, e.g. in anatomy reconstruction from tomographic measurements or in the process of aligning intra-operative navigation and preoperative planning data. In such scenarios, one usually has to deal with sparse data, which significantly aggravates the problem of reconstruction...
