Title
Shape and Albedo Recovery by Your Phone using Stereoscopic Flash and No-Flash Photography
Abstract
Recovering shape and albedo for the immense number of existing cultural heritage artifacts is challenging. Accurate 3D reconstruction systems are typically expensive and thus inaccessible to many and cheaper off-the-shelf 3D sensors often generate results of unsatisfactory quality. This paper presents a high-fidelity shape and albedo recovery method that only requires a stereo camera and a flashlight, a typical camera setup equipped in many off-the-shelf smartphones. The stereo camera allows us to infer rough shape from a pair of no-flash images, and a flash image is further captured for shape refinement based on our flash/no-flash image formation model. We verify the effectiveness of our method on real-world artifacts in indoor and outdoor conditions using smartphones with different camera/flashlight configurations. Comparison results demonstrate that our stereoscopic flash and no-flash photography benefits the high-fidelity shape and albedo recovery on a smartphone. Using our method, people can immediately turn their phones into high-fidelity 3D scanners, facilitating the digitization of cultural heritage artifacts.
