摘要
以SPOT 5及ETM+遥感影像为基础数据,通过对云南昆明郊区利用PCA法和Brovey法进行影像融合,使融合后影像同时具有多光谱特性和高分辨率,提高影像的解译度。并对融合后的影像进行分类及精度分析,讨论影像融合技术在土地调查中的应用。
Taking SPOT5 and ETM ＋ remote sensing image as basic data, this paper implemented the image fusion for the suburb of Kunming in Yunnan using PCA method and Brovey method. The fusion image both has the characteristics of multispectral information and high spatial resolution enhancing the interpretation capability. Then it classified the fusion image and analyzed the accuracy, and discussed the application of image fusion technology for land investigation.
