基于Titan Image软件的QuickBird影像融合

摘要

基于北京东方泰坦科技股份有限公司研发具有完全自主知识产权的Titan Image7.0遥感图像处理软件平台,对QuickBird标准组合(全色0.61 m+多光谱2.44m)影像进行像素级融合,探讨Titan Image7.0遥感图像处理平台在影像融合及评价方面的应用.结果表明:该软件以友好的全中文界面,在同一平台上以简单的操作过程即可完成影像的融合过程与质量评价指标的求算,不仅有效的避免了跨平台、语言差异等因素带来的操作不便与信息损失,而且丰富的融合算法和质量评价指标,可以完成多种影像数据的融合和质量评价；从QuickBird影像融合与质量评价结果来看,参与融合的4种算法中以Pansharp融合算法最好,其次为小波变换算法,IHS算法、PCA算法融合效果最差,这与前人的研究结果基本一致.因此,可以认为Titan Image7.0软件是一种非常好的遥感影像融合平台.%The Titan Image 7.0 software platform of remote sensing image processing was developed by Beijing Oriental TITAN Technology Co, Ltd. Based on this software, the combination of standard spectral (Panchromatic 0. 61 m+multispectral 2.44 m) of QuickBird image was processed in image pixel level fusion. The application and evaluation of this platform in image fusion were carried out. The results show the software has the friendly Chinese interface with a simple operation for the image fusion process and quality evaluation index calculating on the same platform. This platform not only can avoid the inconvenience and loss of information by cross-platform, language differences and other factors, but also can complete a variety of image fusion and quality assessment based on the rich integration of algorithms and quality evaluation. From the results of QuickBird image fusion and quality evaluation, the best image fusion method is Pansharp, followed by the wavelet transform, the IHS and PCA. The results are basically consistent with the previous findings. Therefore, Titan Image 7. 0 software is a good remote sensing image fusion platform.
