摘要 为解决遥感图像反立体现象给使用者带来的不便,加强遥感图像的使用,提出一种基于反DEM结合太阳光照和HSV颜色变换的遥感图像反立体校正方法,并以高黎贡山地区的IRS遥感图像为例与原有的方法进行了对比试验。结果表明:所提出方法在原始图像色彩保留、原始图像阴坡区域的校正效果及原始图像光谱信息保留方面都要优于原有方法。 A correction method for false topographic perception phenomenon was brought forward based on inverse DEM,solar illumination and HSV transformation,in order to solve the inconvenience caused by the false topographic perception phenomenon of the remote sensing images and enhance the application of remote sensing images.An experiment on IRS images of Gaoligong Mountain area was conducted to compare the new method with the previous method.Result indicates that the new method is superior in the color preservation,correction effect of the shaded slope region and spectral information preservation of original images.
