提出了一种用于三维（M）表面高度测量的彩色结构化图案投影的条纹移动新方法。彩色条纹的时间编码与多个条纹的局部空间移位相结合，实现了少量图案投影的图像采集。通过借助移位模式和时间和空间邻域中的编码模式提供的冗余信息对每个条纹的码字进行解码，以高分辨率检索对象形貌。评估弯曲管形状的应用证明了该方法的有效性。 (C) 2008 年美国光学学会。
A new method of fringe shifting for color structured pattern projection is presented for three-dimensional (M) surface height measurement. Temporal encoding of color stripes is combined with locally spatial shifting of multiple fringes to realize image acquisition with a small number of pattern projections. Object topography is retrieved with high resolution by decoding the code word of each fringe with the help of the redundant information provided by the shifting patterns and the encoding patterns in their temporal and spatial neighborhoods. An application to evaluate the shape of a buckled tube demonstrates the effectiveness of the method. (C) 2008 Optical Society of America.
