| 摘 要： | 在遥感应用中,要将遥感影像的空间信息转换到其他坐标系中,一般通过几何校正来实现。这种方法工作量大而且不可避免会引入新的误差。本文从坐标转换的角度出发,通过事先计算两个坐标系之间的转换参数,结合遥感影像中储存空间信息的方式,推导出遥感图像坐标转换的计算公式,并由此推导出根据坐标转换参数计算重采样像元坐标变换函数。根据本文提出方法,可以很方便地实现遥感图像的坐标转换,将遥感图像的空间信息转换到不同坐标系下。

| Abstract: | Spatial information of remote sensing images need to be transformed to other coordinates systems in remote sensing applications,which is commonly accomplished by geometric correction.It needs hard work and will bring new error to remote sensing images.Based on the coordinate transformation,the transformation parameters between two coordinate systems are calculated in advance.Then coordinate transformation formula as well as function of remote sensing images is deduced on the basis of the way by which spatial information is stored in remote sensing images.As a result,coordinates can be easily transformed and spatial information of remote sensing images can be transformed to different coordinate systems with this method. |
