| 摘 要： | 提出一种新的光栅条纹投影轮廓测量术系统标定模型，新模型不要求投影装置和成像系统的光心连线与参考面平行、成像系统的光轴垂直于参考面及投影装置和成像系统的光轴相交。基于该模型得出了新的相位高度映射关系，其待定系数与成像点的坐标无关。实际测量中只需2个高度不同的标准块便可以求得待定系数。对4个标准块进行高度测量，得到的最大相对误差为0.6%。实验证明:该标定方法简单有效，提高了系统标定的可操作性和测量精度。

| Abstract: | A novel system calibration model in fringe projection profilometry (FPP) was proposed, which does not require the connecting line between two optical center parallel to the reference plane, the optical axis of the imaging system is perpendicular to reference plane and the two axes intersect. The coefficients of the phase-to-height relationship can be deduced by using only two different height gauge blocks, which are irrelevant to the coordinate system. The maximum relative error is 0.6% among 4 measured gauge blocks. The experiments demonstrate that this calibration method is flexible and the accuracy is high. |
