摘要
综合利用多种不同遥感卫星获取的数据,可以较为全面地反映观测对象的几何和物理特性,有利于后续影像融合、影像分类等操作的进行,但是不同传感器设计各异,使多源影像自动配准难度重重。为此本文首先对自动配准的流程进行简要介绍,进而对国内外多源遥感影像的自动配准技术进行了分析和评述,最后总结了多源遥感影像自动配准技术面临的主要问题,并展望了其未来的发展方向。
By integrating the multi-sensor images together,the geometry and physical features of observation object can be depicted roundly,which makes the subsequent processing such as image fusion,image classification and so on more convenient.But the different design between sensors causes a big difficulty in automatic registration between multi-sensor images.In this paper,first the flow of automatic registration is introduced briefly,then the techniques of automatic registration of multi-sensor remote sensing images are reviewed and analyzed.At last the difficulties of automatic registration of multi-sensor images are summarized,and the prospects are presented.
