基于插值法对可编程成像系统中莫尔条纹的处理研究

在可编程成像系统中,由于编程器件与感光器件空间频率不同,会产生莫尔条纹。为了降低莫尔条纹对图像质量产生影响,使用插值法对系统产生的莫尔条纹进行处理。首先得到系统莫尔条纹的补偿图像,然后对图像进行直接插值处理。由于被拍摄物体成像后存在光强差异,因此产生莫尔条纹的光密度也会随着光强而变化。使用这种插值与补偿图像相结合的方法对系统采集到的图像处理,得到的结果图像清晰,无明显莫尔条纹,达到了系统要求。

Research on the disposal of Moiré fringe in programmable imaging system based on interpolation

For programming devices have different spatial frequencies with photosensitive devices,a Moiré fringe appears in programmable imaging systems.To reduce the impact which is caused by Moiré fringe on the image quality,an interpolation method is used to handle the Moiré fringe in the system.Compensation image of system Moiré fringe is gained first and then the image is interpolated directly.As the light intensity difference existing in imaging of objects shot,optical density of Moiré fringe will change with light intensity together.The image incepted by the system is processed by a method which is combined interpolation methods and image compensation.The result is image clarity,no evidence Moiré fringe,so it reaches the system requirements.
