摘　　要：为了解决光栅图像噪声抑制问题,提出基于多滤波器组合的光栅图像噪声抑制方法。首先划出光栅图像光滑区域、噪声区域,采用高斯滤波器对两个区域设置不同滤波尺度,滤除图像噪声,经模糊滤波器结合噪声像素点的残余量,处理动态调整滤波窗口大小,抑制光栅图像椒盐噪声。实验结果验证:所提方法对光栅图条纹图像处理的时间最长为15.341 s,对光栅图像噪声抑制后,光栅图条纹图像视觉效果明显变好,目标轮廓清晰,相位信息光滑,且峰值信噪小,得到了较好的光栅图像噪声抑制效果。In order to solve the problem of grating image noise suppression,a method of grating image noise suppression based on multi filter combination is proposed.Firstly,the smooth area and noise area of the raster image are marked out.The Gaussian filter is used to set different filter scales for the two areas to filter out the image noise.After the fuzzy filter is combined with the residual amount of noise pixels,the filter window size is dynamically adjusted to suppress the pepper and salt noise of the raster image.The experimental results show that the maximum processing time of the proposed method is 15.341 s.After the noise suppression of the grating image,the visual effect of the grating image is obviously better,the target contour is clear,the phase information is smooth,and the peak signal-to-noise is small.A good noise suppression effect of the grating image is obtained.
