摘　　要：几何校正是遥感信息处理中一个十分重要的环节,它直接关系到信息提取的精度与实用程度。本文分析遥感图像产生几何畸变的原因,介绍几何校正的原理和方法,以湘中某地区QuickBird遥感图像在ENVI下进行几何校正为例阐述其具体步骤。Geometric correction is one of the important steps in remote sensing processing and related to the accuracy and application during the information extracting. This paper analyzed the causes of geometric distortion of remote sensing image and introduced the principle and method of geometric correction. Taking the QuickBird remote sensing image of the central part of Hunan province as an example, it introduced the processing steps of geometric correction using ENVI.

关 键 词：遥感图像 几何畸变 几何校正 地面控制点
