顾及像面畸变的卫星视频稳像

卫星视频每帧影像外方位元素数值存在差别,相邻帧影像间的同名点在像面位置不同,且由于每帧影像均存在几何畸变,经典的帧间的投影变换模型、仿射变换模型等视频稳像的配准模型不能精确描述帧间的同名点关系。针对该问题,本文提出顾及像面畸变的卫星视频稳像算法,基于仿真的卫星视频,验证了该算法的可行性和精度。...

There is an exterior orientation difference in each satellite video frame,and the corresponding points have different image locations in adjacent frames images which has geometric distortion.So the projection model,affine model and other classical image stabilization registration model cannot accurately describe the relationship between adjacent frames.This paper proposes a new satellite video image stabilization method with geometric distortion to solve the problem,based on the simulated satellite video,we verify the feasibility and accuracy of proposed satellite video stabilization method.
