中文摘要：
亚像元动态成像技术是实现遥感器高分辨、小型化的有效方法.将双三次B样条曲面插值方法应用于亚像元动态成像,利用待插值点周围邻域范围内16个像素点做一张B样条曲面,取曲面中点的值作为待插值点的像素值.文中推导了双三次B样条曲面插值亚像元图像的插值算式,对所提方法进行了计算机仿真研究,并与其他几种常用插值方法进行了性能比较,结果表明,本文算法得到的高分辨率图像效果更佳.
英文摘要：
The subpixel dynamic imaging technique is one of the valid new methods to reduce the size of camera and improve its spatial resolution. The method of interpolation for the subpixel images is realized based on bi-cubic B-Spline surface. The formula of interpolation is given and the method of interpolation is analyzed and it is compared with other kinds of methods. The validity of the conclusions is demonstrated by simulation. The simulation results show that this method has better effect.
