英文摘要：

Video satellites acquire continuous images of targets in a certain time period to dynamically monitor areas of interest in real time. They have become a hot spot in remote sensing satellite development in recent years. In this paper, a survey is given on the development of video satellites and application perspectives of satellite video data. Major challenges facing satellite video are analyzed, focusing on geometric calibration, radiomet- ric calibration, video stabilization, super resolution reconstruction, moving target detection and tracking, 3D reconstruction, and the development trend. Major application fields of satellite video and the future perspectives are discussed.
