摘要
提出了一种基于数据融合的高分辨率彩色核线影像生成方法.首先对全色立体影像与多光谱影像进行融合处理,根据物方投影基准面的卫星影像核线模型由融合影像生成近似核线影像,实现了高分辨率彩色核线影像生成.通过对ZY-3影像进行试验,结果表明所提出的方法具有与全色立体影像相同的量测性能,能真实反映地形地貌特征,而且比全色立体影像信息更丰富,更容易正确解读.
A high-resolution color epipolar image generation method is proposed based on image fusion. A pair of panchromatic stereo images is fused with registered multispectral images. Approximate epipolar images based on projection reference plane （PRP） are then generated according to the practical epipolarity model for linear pushbroom satellite stereo-imagery. Thus, generation of high-resolution color epipolar images is realized. Experimental results of the ZY-3 data show that the proposed method has the same measurement performance in revealing true terrain features, and can provide more information and better visual interpretation.
