摘要

由于从一个彩色图像中可以提取多个条纹,复合条纹投影技术在三维测量领域得到了广泛的研究和应用。为了覆盖所有的光谱范围,投影和成像系统颜色通道间存在着串扰,从而改变了条纹的形状,最终影响三维数据测量的精度。综述了彩色复合条纹投影三维测量系统中颜色通道间串扰的补偿方法。针对彩色条纹投影系统中相机和投影仪颜色通道间的串扰问题,分析了其形成原因。对彩色条纹投影三维测量系统的串扰消除方法进行了分类和总结,并具体比较了各种方法对串扰消除的效果。所综述的方法对选择合适的串扰消除方法、提高彩色复合结构光投影三维测量系统的精度具有重要的应用价值。

Abstract

The composite fringe projection techniques have been widely studied and applied in many fields because multiple fringe patterns can be extracted from single color image. Crosstalk between color channels exists in projecting and imaging systems in order to cover all the range of spectrum. Therefore, the obtained fringe patterns are deformed and the measurement accuracy of three-dimensional (3D) shape data is affected. The compensation method of crosstalk between color channels in color composite fringe projection 3D measuring profilometry is reviewed. The crosstalk between color channels is analyzed with respect to the camera and projector in color fringe projection system. The corresponding crosstalk elimination methods are classified and summarized. The effects of these elimination methods are also compared. The reviewed methods have important application value in choosing the appropriate crosstalk elimination methods and improving the accuracy of color composite fringe pattern projection profilometry.
