Subpixel imaging method is an effective way of increasing the resolution of remote sensing image, which acquires image series of the same target, relatively shifted by fractions of a pixel, and obtains a high resolution image by processing the low resolution image series. A subpixel imaging testbed was built by using a electric control stage, an area CCD sensor, an image acquisition card as hardware, developing control software based on Lab VIEW platform, the function of acquiring subpixel image series was implemented. The test results showed that this testbed acquires the subpixel image series with high registration precision. The testbed is a good foundation for further research.%亚像元图像融合方法是一种提高遥感图像分辨力的有效方法,通过融合两帧对同一目标成像的、错开1/2像元的亚像元图像序列,得到分辨力更高的图像.本文以电控直线导轨、面阵CCD探测器、图像采集卡为硬件,基于LabVIEW开发控制软件,搭建了亚像元成像实验平台,实现了采集亚像元图像序列的功能.通过测试实验证明,该系统采集的图像配准精度极高,为下一步研究亚像元图像融合算法打下了良好的基础.
