Lumio3D: rapid 3D geometry and reflectance acquisition from continuous spherical illumination

Abstract

We demonstrate a prototype of a rapid 3D scanner that can capture both the geometry and reflectance properties of an object under 30 seconds. The scanner utilizes custom made LED panels to provide continuous illumination on an object sitting on a rotatable base. Six cameras will be used for capturing images from various viewpoints under different illuminations. The images are then used for creating reflectance maps and later reconstructing the 3D geometry, albedo and specular maps. The resulting geometry and the maps are also of high resolution. The resulting model and maps can be used for photo-realistic interactive rendering of the object through our webbased viewer. The main advantages of our scanner design compared to state of the arts [Weinmann and Klein 2015] will be the improved speed and reduced artifacts due to moving parts.
