摘要
高分辨率卫星影像由于高空间分辨率和立体成像观测使得数据量通常很大,建立一个快速操作高分辨率卫星影像数据的平台非常必要。本文利用GDAL开源库研究建立了高分辨率卫星影像数据操作平台,主要包括大数据量卫星影像读取、显示、缩放、平移、截取等基本操作。在此平台基础上,利用有理函数模型进行立体影像几何定位,实现了高分辨率卫星影像立体量测。
Because of its high spatial resolution and three-dimensional imaging observation,high-resolution satellite imagery(HRSI)data is usually very large,which makes it very necessary to establish a fast operation platform for high-resolution satellite image data.In this paper,we utilized the open source GDAL library to build HRSI data platform that includes a lot of basic operations of satellite image data such as read,display,zoom,pan and interception.Based on this platform,we used Rational Function Model for three-dimensional image geometric positioning and achieved three-dimensional measuring for high-resolution satellite images.
