Abstract
Global illumination effects such as inter-reflections,
diffusion and sub-surface scattering severely degrade
the performance of structured light-based 3D scanning.
In this paper, we analyze the errors caused by global
illumination in structured light-based shape recovery.
Based on this analysis, we design structured light pat-
terns that are resilient to individual global illumination
effects using simple logical operations and tools from
combinatorial mathematics. Scenes exhibiting multi-
ple phenomena are handled by combining results from
