| 摘 要： | 大地校正和数字图像镶嵌是应用遥感图像进行资源环境监测工作的基础,其精度的高低将对后续工作产生直接影响。基于经过系统校正的TM图像内部几何精度高的前提,本文提出一种快速实用的大地校正及图像镶嵌方法,该方法避免了传统方法在应用控制点建立拟合方程时耗时长的缺点,保证了TM镶嵌图像的几何精度. |

| Abstract: | Earth Correction and Image Mosaic are the basis of using TM image to monitoring resource and environment. The accuracy of registration is the key factor for the follow_up work. The traditional method, which selects control-points to set up equation, tends to take long time and result in geometric distortion. This paper puts forward a rapid and practical method based on the high internal geometric accuracy of TM image. Tests show that the method is characterized by high speed and high registration accuracy. |
| Keywords: | Image mosaic Internal Geometric Accuracy Geometric distortion |
