| 摘 要： | 几何校正将引起几何校正前后像元的像素值发生变化,进而导致暗像元的辐亮度在几何校正前后存在偏差.本文以太湖为研究水区,以2003年10月28日的Landsat/TM影像、2008年7月24日的CBERS影像和2009年4月25 日的HJ-1B影像作为数据基础,研究与探讨了几何校正对暗像元大气校正算法以及离水辐亮度反演精度...

| Abstract: | The pixel values would be different before and behind the geometric correction,which would lead to the different irradiance of dark pixel before and behind the geometric correction.Regarding the Lake Taihu as the study area and using the Landsat/TM,CBERS and HJ-1B satellite imageries,data collected at October 28,2003,July 24,2008 and April 25,2009,respectively,as the data foundation,the paper researched and discussed the influences of geometric correction on the accuracy of dark pixel atmospheric correction... |
