摘要
在以CCD为核心器件的光电成像测量系统对物体进行线度测量中,成像光学系统的固有特性使得数字图像存在畸变,根据像差理论建立了三次多项式的畸变校正模型,分析比较了不同的灰度重建方法的优缺点,进行了双线性插值的灰度重建.对一种校正图像进行了噪音点滤除,进行了仿真实验.校正后的图像可用于高准确度的成像测量.
The digital image has distort measuring body＇s scale through high pr a core component. The distortion mode The scale rebuild was progressed afte interpolation method. The image＇s nois image is approve of fitting high precisio ion because the inherent characteristic of imaging optical system in ecision measurement system based on the CCD camera was used as 1 of 3^th polynomial was found based on primary aberration theory. r analyzing and validating the excellence and defect of different e contrapose one of correction methods filter off.
