轮廓的尺寸量、位置量以及形状误差估计值的不确定度与测量误差、被测轮廓的形状特征以及采样策略等有关。
Sampling strategy, measurement errors and measured contour form features are all related to the uncertainty analysis for dimension, position and form error estimated.
然后投射到被测物体表面，计算未发生形状变形处的相位，即为由产品定位不精确引起的相位变化量。
Secondly, fringe analysis techniques are adopted to acquire the phase when referenced sample is perfect positioned; the same way is employed onto the product which is inaccurate positioning.
