基于多角度卫星影像制作 DSM，DEM数字产品的方法研究

摘要

With the development of multi-angular satellite, the application of multitier is also developed.The multi-angular satel-lite can provide stereo pair and multi-angle observation data at the same time which provide a possibility of extracting elevation.This paper is based on the cartosat1 satellite and discussed the methods of producing 3D products.Its development prospects were dis-cussed.%随着多角度卫星的不断发展，多角度的应用也随之而来。由于多角度观测卫星可同时提供多角度观测数据，提供立体像对，从而为提取影像高程信息提供了可能。本文基于Cartosa1t 卫星获取的多角度卫星影像，对DSM、DEM等数字3D产品的生成方法进行了论述，对其发展前景做了展望。
