Polarization Imaging Applied to 3D Reconstruction of Specular Metallic Surfaces
نویسندگان
چکیده
This paper presents a new application of “Shape from Polarization” method to specular metallic surfaces. It demonstrates how to extend the commonly used method for dielectric to metallic surfaces. Studying the state of polarization of the reflected light is very useful to get information on the normals of the surface. After computing the surface normals, the 3D surface is reconstructed thanks to a relaxation algorithm. Applications on shape defects detection are discussed, and the efficiency of the system to discriminate defects on metallic objects made by stamping and polishing is presented.

Active Lighting Applied to 3D Reconstruction of Specular Metallic Surfaces by Polarization Imaging
In the field of industrial vision, the three-dimensional inspection of highly reflective metallic objects is still a delicate task. This paper deals with a new automated 3D inspection system based on polarization analysis. We first present an extension of the ‘Shape from Polarization’ method for dielectric to metallic surfaces. Then, we describe a new way of solving the ambiguity concerning the...
متن کامل3D digitization of metallic specular surfaces using scanning from heating approach
Because of the difficulty of dealing with specularity of several surfaces, few methods have been proposed to measure three-dimensional shapes of specular metallic objects. In this paper we present an application on this kind of material of an approach called “Scanning From Heating”. This approach has been developed initially for 3D reconstruction of transparent objects. This article presents an...
متن کاملReconstruction of Specular Surfaces using Polarization Imaging
Traditional intensity imaging does not offer a general approach for the perception of textureless and specular reflecting surfaces. Intensity based methods for shape reconstruction of specular surfaces rely on virtual (i.e. mirrored) features moving over the surface under viewer motion. We present a novel method based on polarization imaging for shape recovery of specular surfaces. This method ...
متن کامل3D Reconstruction of Specular Objects with Occlusion: A Shape-from-Scattering Approach
In this paper, we propose a method to measure specular objects regardless occlusion. The main contribution of this paper is that we have shown that the scattering of incident and specular reflection enable us to measure occluded surfaces. We locate objects in a tank filled with participating media, irradiate a laser beam to the objects, and observe the scattering of incident light and specular ...
متن کاملAn Introduction to Image-based 3D Surface Reconstruction and a Survey of Photometric Stereo Methods
1 This paper provides an introduction to photometric methods for image-based 3D shape reconstruction and a survey of photometric stereo techniques. We begin with taxonomy of active and passive shape acquisition techniques. Then we describe the methodical background of photometric 3D reconstruction, define the canonical setting of photometric stereo (Lambertian surface reflectance, parallel inci...
