摘要
以不同像移探测需求为导向,梳理了像移探测方法的发展脉络,将像移探测历程划分为基于工程参数的像移计算、基于联合相关器的像移估计和基于遥感图像的像移探测三个阶段;客观分析了每个阶段所解决的问题及面临的瓶颈;结合空间相机的发展趋势,剖析了目前像移探测方法中迫切需要解决的三个关键科学问题,为宽频带像移探测提供了一种可能的研究思路。
Abstract
Taking different requirements for image motion detection as orientation, the development of image motion detection methods is traced, and the whole detection process of image motion is clarified as three stages: image motion calculation based on engineering parameters, image motion estimation based on joint optical correlators, and image motion detection based on remote sensing images. For each stage, the existing solved problems and the remaining technical bottlenecks are analyzed objectively. In combination with the development trend of space cameras, three pivotal scientific problems that need to be solved in the existing image motion detection methods are deeply analyzed. This study provides a possible research thought for wide-band image motion detection.
