基于资源三号卫星影像的数字表面模型快速生产及精度分析

随着国产遥感卫星影像资源的日益丰富,基于国产遥感卫星影像的应用与研究也逐渐成为焦点。目前,充分利用国产卫星影像,逐步减少使用国外遥感影像,是我国现代测绘产业发展的大趋势。论文基于资源三号国产卫星影像,分别在稀少控制点、足够多控制点的条件下,研究快速生产DSM的技术流程,并对其精度进行对比分析,对基于国产高分辨率遥感卫星影像的现代测绘产品快速生产具有重要的理论意义和实践意义。

Rapid Production and Precision Analysis of Digital Surface Model Based on ZY-3 Satellite Imageries

With the development and rich of indigenous satellite images , the application and study base on satellite images become fo-cus little by little.At present, adequately utilize indigenous satellite images , step by step reduce overseas satellite images , becoming the tendency of modern surveying and mapping industry .The paper base on resource three satellite images , in conditions of few control points and enough control points respectively , study the skill flow of product DSM quickly , proceeding comparison and analysis of pre-cision.The study has important theory meaning and practice meaning of modern surveying and mapping industry base on domestic high resolution images .
