【摘要】 遥感(RS)技术在高等级公路工程中的应用正不断发展,而RS图像的计算机自动分类解译是RS数据解译计算智能化和自动化的关键技术之一.本支通过分析RS图像的物理基础,分析了传统的分类方法的弊端,指出基于广义夹角的计算机分类方法(SAM法)较适合地物光谱的形状特征,进而对SAM法进行研究并提出了改进方法和实施步骤,给出了分析比较试验实例.说明其研究改进使分类计算精确.更多还原

【Abstract】 The application of RS technique is developing continuous in the express highway engineering and The computer automatic classification expounding of RS image is one of key technique on RS Date expounding and computing .This paper analyzed tradition classification absence by studying physical base of RS image ,point out the SAM method suit to shape feature of surface spectrum, and studied that, advanced the improving way and implement step ,then it gave out example about analysis is comparison experiment ,and showed ’ that studied improving made classification more accurate .更多还原
