摘    要:基于投影栅线的三色条纹相移算法与投影栅线法相结合,提出一种数字三色条纹相移形貌投影栅线法.此法是对时间相移法的改进,只需一幅三色条纹图,就可利用简单的三光强相移算法完成物体表面的形貌重建;不需要相移装置而误差较小,成本较低,简易实用,将有利于推广到动态实时分析.实验证明,此法是正确可行的.

关 键 词:形貌重建  投影栅线法  三色条纹  相移法

Abstract:The tricolor fringe phase-shifting technique in digital projection grating profilometry to reconstruct the profiles of object surface is proposed.The technique improves the time phase-shifting technique.Only one fringe pattern is used to reconstruct the profiles of object surface by the advanced technique combined with a simple three-step phase-shifting algorithm without any phase-shifting devices.The proposed technique is economical and practical and maybe use for the dynamic rea-time analysis.The experiment illuminates that the technique is right and feasible.
Keywords:Profile construction  Projection grating profilometry  Tricolor fringe  Phase-shifting algorithm
