英文摘要： Information extraction based on satellite video belongs to the interdisciplinary research field of photogrammetry and computer vision,which has broad application prospects. Owing to the plane array video satellite platform and payload features, considering the poor stability and difficulty in information extraction of satellite video,this project will propose high-resolution video moving target detection and track extraction method based on the theory of aerospace photogrammetry ;through satellite video imaging geometry in-depth analysis, the gaze satellite video image stabilization method is studied; this project researches detection and tracking algorithm for rigid body motion targets (including point and area targets) in satellite video; with strict geometric relationships based on satellite-to-ground video imaging,the ground three-dimension moving target track extraction method and velocity calculation is studied.This project will provide a solid theory basis and implement methods for the application on satellite video motion detection, tracking ,and prediction. The project fills in gaps in video satellite data processing methods and applications, thusing being of great significance for video satellite exploration in remote sensing field.
