基于资源三号三线阵影像快速制作DSM 生产应用研究

摘要

主要利用资源三号卫星影像进行稀少控制定向和选择不同视影像组合分别进行DSM产品快速制作试验，并对试验结果进行主观和定量评价，分析利用资源三号三线阵影像快速制作DSM产品的流程及适用条件。%This paper mainly discuss the DSM product rapid producing test using ZY -3 satellite images by sparse control and choo-sing different visual images combination .In this paper we evaluate the test results subjectively and quantitatively , we analyze the work flow and applicable conditions of rapid DSM producing using three -line array images of ZY-3.
