SPOT-5影像融合技术在西部测图工程中的应用

本文针对西部干燥荒漠地区的地貌地表影像,进行了基于信息量的波段选取和融合试验,获取了一定的经验值,将此经验值应用于相似类型地表的影像融合后,取得了良好的效果。经实际生产作业证明,基于信息量理论选取的组合波段,能很好地保持原始影像的光谱特征,且融合后,影像层次丰富、色彩逼真。

Technique of SPOT-5 image fusion and practice in Western Mapping Project

Western Mapping Project Kunlun Mountains area(edge of the Tarim Basin) is typical of dry desert,surface exposed and cut broken;the quality of Remote Sensing Image that obtained from SPOT-5 satellite is generic.The selection of bands and fusion test were carried out in the paper,to get some experience in value,the value of this experience in similar type of surface used in image fusion,and achieved good results.It was proved by the actual production work,based on the selected combination of information theory band based combination bands could well maintain the spectral characteristics of the original image,and the fused image with rich layers and fidelity color.
