Paper Abstract

This paper proposes a comparative survey on techniques of vision based on invisible structured lighting. We have classified them in three distinct families: InfraRed Structured Light (IRSL), Imperceptible Structured Light (ISL) and Filtered Structured Light (FSL). For each of them, definition, minimal configuration and main applications found in the literature are given. Then, we compare them regarding to several criteria: required equipment, light pattern coding, color analysis, texture analysis, motion analysis, security, use in non-controlled environment. The description is IRSL, ISL and FSL sensors will permit to sum up these techniques; the comparison will permit to evaluate performances and efficiency of each of them. We think that this study could be useful to researchers that are looking for a compromise between stereovision and structured light vision, combining the processing tools extent of the former with the point matching reliability and simplicity of processing of the latter.
