摘　　要：根据干涉场的条纹灰度分布规律 ,对条纹图象进行处理。用多项式对条纹数据进行拟合 ,提高了条纹提取的速度和精度 ,同时也起到了噪声抑制的作用。用求极值的方法确定每次采样条纹中心点的位置 ,再把所有的中心点组合起来表示条纹的形状 ,从而达到提取条纹的目的。The fringe image is processed according to fringe gray distribution rule in interference field.Fitting the fringe data with polynomials can improve the speed and accuracy in fringe extracting,and restrained the noise at the same time.The central point for each sampling fringe is determined by seeking extreme.All the central points are combined for representing the shape of the fringe,thus the goal for extracting fringe can be carried out.
