| 摘 要： | 为纠正太阳同步卫星所获取的山地地形遥感图像中存在的反立体现象,以四川省广元市某区的遥感图像为例,尝试一种基于DEM和IHS变换的遥感图像反立体纠正方法。该方法用DEM制作的地形阴影图替换IHS变换得到的亮度(I)分量后进行IHS反变换,能有效纠正遥感图像上的反立体现象,并与原图像色彩基本保持一致。

| Abstract: | In order to remove the false topographic perception phenomenon existing in the remote sensing images obtained by sun-synchronous satellites of mountainous area,this paper brought up a method based on DEM data and IHS transformation and took a case study on an image of Guangyuan city in Sichuan Province.After replacing the intensity image obtained by IHS transformation with the terrain shade image produced by DEM,a back IHS transformation was done to acquire corrected RGB image.The results of experiment indicate that the method can remove the false topographic perception phenomenon effectively and maintenance the primary hue. |
