摘要:
针对目前遥感商用软件影像镶嵌过程中人工干预过多、自动化程度不高和不易修改等问题,提出了基于平面剖分的遥感影像镶嵌模型.模型基于开源类库空间数据抽象库(geospatial data abstraction library,GDAL),在GNU/Linux平台下,使用Python语言,实现了遥感影像按研究区域进行掩模及镶嵌的功能,并采用模型—视图—控制器(model view controller,MVC)的设计模式,应用跨平台的图形用户界面(graphical user interface,GUI)库wxPython实现了软件的封装,提供了完整的、功能键全的GUI用户界面.程序可以基于GUI界面或命令行方式运行,参数简单、可定制性强、可以批处理数据,提高了影像镶嵌自动化水平,在东北土地利用数据库更新中被用于Landsat5 TM影像镶嵌.
Abstract:
A plane split model was designed to resolve the problems of manual intervention dependency, low automation and difficulty in modification during remote sensing image mosaicking. Based on the GNU/Linux system, segmentation and mosaicking of experimental remote sensing images were carried out by Python and open source geospatial data abstraction library ( GDAL ) . The set of algorithms was encapsulated by wxPython in the model view controller ( MVC ) framework. The design of the software with graphical user interface ( GUI ) is so perfect that it not only can be operated by GUI or command line, but also can process large numbers of images in batch. It has been well received to mosaic Landsat5 TM images in Land Cover Database Updated Program of Northeast China.
