View and Path Planning for Large-Scale 3D Acquisition 

Demand for high-volume 3D scanning of real objects is rapidly growing in a wide range of applications, including online retailing, quality-control for manufacturing, stop motion capturing for 3D animation, as well as archaeological documentation and reconstruction. Although mature technologies exist for high-fidelity 3D model acquisition, deploying them at scale continues to require non-trivial manual labor. In this talk, I will present a system that allows non-expert users to scan large numbers of physical objects within a reasonable amount of time, and also with greater ease. I will describe the design of a structured-light scanner and positioning system, which are optimized for acquisition of relatively small objects, such as fragments of archaeological artifacts. I will also discuss novel view- and path-planning algorithms that enable automatic 3D acquisition, and demonstrate the ability of our prototype to safely, robustly, and automatically acquire 3D geometry and color models for large collections of small objects, such as toy soldiers and fragments of ancient artifacts.
