Paper Abstract

The principle of spatial periodicity used for coding is proposed in the paper, the maximum stripe deformation (due to depth change on surface) and measuring resolution limit is analyzed. When spatial periodicity is used for coding, the resolution is greatly improved, or the number of pattern is greatly reduced for real-time structured light systems. When spatial periodicity is exploited in coding design, the number of coding is limited according to the principle of spatial periodicity, which is the maximum of measuring resolution is determined. Or when spatial periodicity is used in coding design, bottom limit of patterns is defined, which is maximum response speed in real-time structured light system. A novel coded pattern based on spatial periodicity for real-time structured light system is presented. These coding patterns allow range scanning of moving objects with high measurement resolution.
