| 摘 要： | 随着数字正射影像(DOM)的广泛应用,对正射影像的质量要求也越来越高。影像匀光、匀色处理是制作正射影像时的一个重要环节,它决定着正射影像色彩的优劣。本文主要介绍以低层级谷歌影像为参考基准色,对天绘多光谱影像DGP进行颜色匹配法匀光、匀色;利用波段调整功能对天绘多光谱影像DGP进行绿色增强;采用Pansharp最小二乘法对多光谱影像DGP和高分辨率影像GFB进行影像融合,从而获得如谷歌影像一样丰富的纹理层次感强、色彩真实的彩色天绘正射影像。

| Abstract: | With the widely application of the DOM , the quality of DOM demand is higher and higher .Unifier ray and color of the im-age is an important part in the produce process of orthography images ,the stand or fall of it decides the color of the orthography ima-ges.This paper mainly introduces the unifier ray and color of Tianhui multispectral image ( DGP) in the way of color matching with the low levels of Google image as the color of a reference datum;enhancing the green band of Tianhui multispectral image ( DGP) with the function of band adjustment;Using the least square method for image fusion of high resolution image ( GFB) and multispectral im-age ( DGP) to gain the colored orthography image of Tianhui which has rich color information like Google image , real color and strong lays of graphics . |
