"Mobile Surface Reflectometry"
ACM SIGGRAPH 2014 Posters, August 2014
Abstract
We present two approaches for acquiring spatially varying reflectance of planar samples using a mobile device. For samples with rough specular BRDF, we propose to employ the back camera and flash pair on any typical mobile device for freeform handheld reflectance acquisition using dense backscattering measurements under flash illumination. For samples with highly specular BRDF, we instead employ a 10" tablet for illuminating the sample with extended illumination while employing the front camera for reflectance acquisition. With this setup, we also exploit the tablet's LCD screen polarization for diffuse-specular separation.
