| 摘 要： | 为了克服传统大气校正效率低、精度差和自动化程度不高的缺陷,提高LAND-SAT TM/ETM数据大气校正的效率和精度,达到用计算机来代替传统手工作业的目的,依据线性回归法大气校正原理,借助专业遥感图像处理软件ERDAS IMAGINE的空间建模功能,构建了大气自动校正模型.通过与传统手工作业方法对比得出,在效率上,自动校正模型比传统手工作业高出60~100倍;在精度上,也比传统手工作业方式提高了1~5个DN值.证明了该模型具有一定的可靠性和实用性.

| Abstract: | In order to overcome the weakness of conventional method of atmosphere rectification in low efficiency,the bad precision and low-level automation,to improve efficiency and precision for LANDSAT TM/ETM data and achieve the goal of utilizing computer instead of conventional way,in this paper,based on the atmosphere rectification principle of linear regression method,a automatic model by ERDAS IMAGINE software is built up.Compared with the conventional method,the automatic model is 60~100 times higher than that in conventional method in efficiency and improves 1~5 DN value in precision.The results show that the automatic model has some reliability and practicability. |
