摘要
现有基于遥感的矢量电子地图自动化质量提升方法较少,且传统方法效率低,研究区域受限,精度满足不了生产要求。针对这一问题,本文提出基于遥感匹配的矢量电子地图质量快速提升的方法。核心思路是:以项目实验为基础,基于IDL语言编程实现影像匹配获取同名点并进行坐标转换,运用GIS软件的配准功能对矢量数据进行空间配准,实现矢量电子地图与影像的匹配。试验证明:采用影像匹配算法,矢量电子地图质量提升更灵活,效率更高,能够大幅度的提升矢量电子地图的质量。
The current automatic methods of the vector electronic map to improve the quality based on remote sensing are less,and the traditional methods have low efficiency,and has regional restricted,so the accuracy cannot meet the production requirements.To solve this problem,the approach of the vector electronic map quality improved rapidly based on remote sensing match has been proposed in this paper.The core idea as with project lab,to achieve access the same name points by image matching and coordinate conversion based on IDL programming language,the vector data was spatial registrated using GIS registration function,to achieve matching of vector electronic map and image.The results proved that using the image matching algorithm,the vector electronic map to improve the quality is more flexible and efficiently,and can enhance the quality of vector electronic map greatly.
