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.
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 re- gression 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.
