摘要
采用编码条纹投影解相位技术,通过向物体投影6 幅经过格雷编码的二值条纹图与4 幅周期为2N - 1 的正弦条纹图,来实现相位的求解。这种方法实现了边缘陡峭物体的测量,同时提高了相位解包的准确性。与传统方法相比,这种方法能够测量物体的阶跃特性,且投射高频条纹能够提高测量精度。
Abstract
The way of encoded fringe projection is taken through projecting six binary fringe patterns after gray coding and four sinusoidal fringe patterns with the cycle of 2N - 1 into the object to unpack phase. This method achieved a measurement of object with steep edge, and improved the accuracy of phase unwrapping at the same time. Compared with traditional methods, this method can measure the step characteristics of object, and the measurement accuracy can be improved when high frequency fringe is projected.
