dc.description.abstractThis study proposes a method based on Spatial Augmented Reality (SAR) technology to transform the perceived material of an object's surface by projecting imagery rendered from measured BRDF data. The core of this method lies in the non-contact estimation of the object's three-dimensional surface shape from images captured at four different polarization angles. Specifically, Stokes parameters are calculated from four polarized images, and a normal vector is derived for each pixel based on the resulting Angle of Linear Polarization (AoLP) and Degree of Linear Polarization (DoLP). Next, rendering is performed using the estimated normal map and a measured BRDF database. The resulting appearance of the target material is then projected onto the object via a projector-camera system. Experiments demonstrate the ability to change the material appearance of certain objects, such as plaster statues and plastic products. The significance of this research lies in demonstrating a new framework for presenting material appearance by combining shape estimation using polarization with physically based rendering.en_US
