影响条纹图形拼接法测量精度的主要误差因素

Factors Influencing on Accuracy of 3 D Shape Measurement Using the Fringe Pattern Connection Method

通过对计算机模拟和实验结果的分析表明，影响条纹图形拼接法测量精度的主要因素是：子孔径面形测量精度、重叠区的大小、面形拟合阶次和拼接模式等。

The fringe pattern connection method (FPCM) is an effective method in 3 D shape measurement of a large object without annoyance of illumination and readout shadows. It has shown that the main factors that effect the final accuracy of 3 D shape measurement using the fringe pattern connection method include the measurement error of subapertures the overlap coefficient K D , the order N f  of polynomial fitting and the mode of aperture connection.
