一种TDI CCD亚像元图像合成方法

Method for Composing Two Images of Tdiccd Sub-Pixel Camera

通过分析TDI CCD亚像元相机输出数据的空间和频谱特点,设计了亚像元插值算法,由相机输出的两幅原始图像经过插值融合处理得到一幅比原图像分辨率高的图像.仿真结果表明,该算法较其它算法得到的高分辨率图像的效果更佳,融合之后的图像比原图像分辨率提高至少1.4倍.

Based on the analysis of frequency spectrum of the images,a method for composing of two images is proposed.By using rhe method the high-resolution image was obtained from the two images of the TDICCD sub-pixel camera.The simulation results show that it was more effective compared to other sub-pixel imaging methods and the resolution of the image can be improved 1.4 times.
