| 摘 要： | 坐标转换是所有的遥感、GIS、航测等软件都必须具备的一个基本功能,在功能实现中会遇到大规模的矩阵运算问题,而灵活运用IDL编程工具中的结构数组运算能大大地简化计算步骤,加快图像处理的速度。本文运用IDL设计了坐标转行算法,对于一幅row(行)、col(列)的图像,在已知该幅图像其中一个像元点在图像中的像元位置和经纬度坐标的情况下,利用该算法能够实现整幅图像中所有点的经纬度坐标的计算,并验证了其正确性。 |

| Abstract: | Coordinate transformation is a basic function in many softwares.This is true especially in the remote sensing,Geographic Information System (GIS),aerial Photogrammetry software.But,the large-scale matrix operation is the most difficult problem that should be solved in the process of coordinate transformation.The flexibly use of structure array computing in the IDL programming tools can greatly simplify the steps of the calculation to accelerate the speed of image processing.In this study the IDL is used to ... |
