摘要
分析了两帧图像的“亚象元”法提高图像空间分辨率的合理性。将“亚象元”技术应用于鉴别率板目标物,并进行三种插值方法的后续数字图像处理,分辨率提高到1.4倍。使用面阵CCD拍摄图片的实验结果显示,图像分辨率提高,同时图像显得细腻,像质提高。此种方法适合于遥感测量。
The rationality is analyzed that the subpixel technology can be used to improve the spatial resolution
of the image. The simulation of standard board for distinguishability test, including image fusion and three kinds
of interpolation,is carried out. The spatial resolution of image increases by 40%. The experimental results show
that the quality and spatial resolution of image are improved and the image looks finer. The technology can be ap-
plied to remote sensing.
