不同分辨率图象的计算机复合方法与效果

Computer-based integration of different resolution images and its effect

以往对不同分辨率图象进行复合时,不管工作如何细致,图象配准得如何精确,由于不同分辨率的影响,使复合产生的新图象质量受到很大影响。 作者结合“75”国家科技攻关项目:多种遥感数据的综合分析,研制了一种新颖和有效的复合方法——IHS变换复合法,使计算机复合处理获得十分理想的图象,在地质与地学信息提取方面获得十分满意的效果。这一方法为多种遥感图象及各种遥感与非遥感图象的复合与综合显示开辟了一条有效的新途径。

When we integrated with different resolution images before,no matter how careful we were and how precise the rectification of image was,the resolution of new image,result from integrated images,was not very good owing to the different resolution of images. So the qual- ity of image was affectde deeply.In combination with the synthesis analysis of multiple remote sensing date, one of the state's major science and technology research projects of Seventh Five-Year Plan,authors have developed a new and effective integration method-IHS transformation integration method. Using it,high quality image has been obtained from computer-based integration processing and the result in terms of the information extraction of geology or geonomy was very satisfactory.This method provides a new and effective way for integration and synthesis display of multiple remote sensing and non-remote sensing images.
