A Method to Estimate Surface Shape of Transparent Objects by Using Polarization Raytracing Method
نویسندگان
چکیده
There are few methods which easily measure the shape of transparent objects easily In this paper we propose a method to estimate the surface shape of transparent objects by analyzing the polarization state of the light Previous methods do not provide enough accuracy because of the lack of deeply analyzing the light re ected refracted and transmitted inside the transparent object Proposed method employs a polarization raytracing method to compute both the polarization state of the light and the re ection refraction and transmission of the light Proposed iterative computation method which minimizes the di erence between the polarization data rendered by the polarization raytracing method and the polarization data obtained by a real object estimates the surface shape of the transparent object with higher precision than previous methods

Polarization-based Shape Estimation of Transparent Objects for Digitizing Cultural Assets
Though there are many cultural assets which are made of glasses, most of the existing methods cannot estimate the shape of transparent objects with enough accuracy. We propose a novel method for estimating the surface shape of transparent objects by analyzing the polarization state of the light. Existing methods slightly consider the reflection, refraction, and transmission of the light occurri...
متن کاملShape Estimation of Transparent Objects by using Polarization Analyses
Today, techniques developed in the field of computer graphics and virtual reality are applied in many scenes, resulting the method of measuring 3D shape of real objects to be more and more important. However, less methods are proposed to measure 3D shape of transparent objects such as glasses and acrylics. In this paper, I propose three kinds of method, which estimate the surface shape of trans...

متن کاملA Time-Domain Method for Shape Reconstruction of a Target with Known Electrical Properties (RESEARCH NOTE)
This paper uses a method for shape reconstruction of a 2-D homogeneous object with arbitrary geometry and known electrical properties. In this method, the object is illuminated by a Gaussian pulse, modulated with sinusoidal carrier plane wave and the time domains’ footprint signal due to object presence is used for the shape reconstruction. A nonlinear feedback loop is used to minimize the diff...
متن کاملMeasurement of Surface Orientations of Transparent Objects Using Polarization in Highlight
This paper proposes a method for obtaining surface orientations of transparent objects using polarization in highlight. Since the highlight, the specular component of reflection light from objects, is observed only near the specular direction, it appears merely limited parts on an object surface. In order to obtain orientations of a whole object surface, we employ a spherical extended light sou...
