摘要
为探索空间分辨率为2.5 m的SPOT5遥感图像用于水土保持监测的可行性,须进行遥感图像几何精校正。在理论分析遥感图像校正模型的基础上,通过实例计算,详细研究各种可能的几何精校正方法及实际精度状况。综合考虑几何位置变换精度、灰度重采样精度,确定适合水土保持监测的SPOT5遥感图像的几何精校正方法。
order to study the probability of SPOTS remote sensing image with a spatial resolution of 2.5 m when used to monitor soil and water conversation,calibration of remote sensing image needs to be carried out. On the basis of analyzing calibration model of remote sensing image from theory,according to real example calculation,the calibration method of SPOTS remote sensing image appropriate for soil and water conversation monitoring is determined by synthetically thinking of the precision of geometry transform,the precision of gray resample.
