MISHA3D - Three-dimensional Surface Capture with the MISHA Multispectral Imaging System

In this paper we introduce MISHA3D, a set of tools that enable 3D surface capture using the MISHA multispectral imaging system. MISHA3D uses a novel multispectral photometric stereo algorithm to estimate normal, height, and RGB albedo maps as part of the standard multispectral imaging workflow. The maps can be visualized and analyzed directly, or rendered as realistic, interactive digital surrogates using standard graphics APIs. Our hope is that these tools will significantly increase the usefulness of the MISHA system for librarians, curators, and scholars studying historical and cultural heritage artifacts.
