摘要
针对二维平面地形图与遥感图像之间同一地区不同比例的融合问题,研究了遥感地形图的几何校正和重采样等技术实现。基于图像处理器(GPU)实现了Linux环境下遥感图像的几何校正,以及带有纹理信息的遥感图像与平面地形图的融合,扩展了传统二维平面地形图的表现形式。
A method for achieving the fusion of remote sensing image with two-dimensional （2D） maps in different scales is introduced. The method includes some technologies, such as geometric correction and resampling, etc. In addition, an approach to achieve the geometric correction of the remote sensing image and the fusion of remote sensing image with 2D map are introduced through graphic processing unit （GPU） in Linux environment, thus improving the displaying ef- fects of traditional topographical maps on computer.
