【摘要】：随着遥感技术的快速发展，遥感技术在资源探测、环境监测和国民经济等诸多方面发挥了越来越重要的作用。作为遥感技术的直接探测结果，遥感图像在波谱分辨率、图像分辨率、空间分辨率等方面也取得了长足的进步，很多相关的图形图像处理技术和数学方法也不断地涌现出来，这就要求遥感图像处理软件可以实现快速地动态扩充，适应这种快速发展。如果每次扩充功能都要改变原始程序的编码、重新编译、发布，不仅费时费力，还可能引起软件兼容性的问题。本文提出并实现了一种可扩展遥感图像处理平台的设计方式，制定了平台默认的遥感图像格式，并提供了格式转换功能，尽可能地兼容现有和未来可能出现的图像格式。平台提供遥感图像读写和图像显示与处理等必要的基本功能，其他的扩展功能可由开发人员根据实际需求进行开发，并以插件的形式添加到图像处理平台之中。平台包含内部服务接口和外部插件接口。平台将部分基本功能进行封装，作为平台服务功能，并对插件开放内部服务接口，插件可通过调用相应的接口实现遥感图像的访问与平台基本功能的使用。插件需要按照平台规定的接口规范进行开发，平台可直接通过插件接口进行调用，插件也可以向其他插件开放接口信息，供其它插件调用。平台提供了插件管理工具，可为插件动态关联一个菜单资源，，在平台初始化时，会根据配置文件动态生成插件对应的菜单，用户可通过图形界面调用插件。平台还制定了数据交换方式，插件可通过调用相应的接口实现插件与平台、插件与插件间的通信功能。通过这种设计方法，已有的开发成果可以得到很大程度的重用，新的研究成果与方法也可以快速地添加到现有的处理平台之中，同时避免了开发基础功能的重复劳动。通过测试证明，本文提出的设计方法可以将新功能、新方法相对简单、快速地添加到现有的处理平台之中，实现功能的扩充，解决相应实际问题。
[Abstract]:With the rapid development of remote sensing technology, remote sensing technology has played a more and more important role in resource exploration, environmental monitoring and national economy. As the direct detection result of remote sensing technology, remote sensing image has made great progress in spectral resolution, image resolution, spatial resolution and so on. This requires remote sensing image processing software to achieve rapid dynamic expansion to adapt to this rapid development. If every extension changes the coding, recompiling and publishing of the original program, it not only takes time and effort, but also may cause software compatibility problems. In this paper, a design method of extensible remote sensing image processing platform is proposed and implemented. The default remote sensing image format of the platform is established, and the function of format conversion is provided, which is compatible with the existing and future image formats as far as possible. The platform provides basic functions such as remote sensing image reading and writing and image display and processing. Other extended functions can be developed by developers according to actual requirements and added to the image processing platform in the form of plug-in. The platform includes internal service interfaces and external plug-in interfaces. The platform encapsulates some basic functions as the platform service function, and opens the internal service interface to the plug-in. The plug-in can access the remote sensing image and use the basic function of the platform by calling the corresponding interface. The plug-in needs to be developed according to the interface specification stipulated by the platform. The platform can be called directly through the plug-in interface, and the plug-in can also open the interface information to other plug-ins for other plug-ins to call. The platform provides a plug-in management tool, which can dynamically associate a menu resource for the plug-in. During the initialization of the platform, the menu corresponding to the plug-in will be dynamically generated according to the configuration file, and the user can call the plug-in through the graphical interface. The platform also has a data exchange mode. The plug-in can realize the communication function between the plug-in and the platform and between the plug-in and the plug-in by calling the corresponding interface. Through this design method, the existing development results can be reused to a large extent, and the new research results and methods can be quickly added to the existing processing platform, while avoiding the duplication of the development of basic functions. It is proved by test that the new function and the new method can be added to the existing processing platform quickly and easily, which can expand the function and solve the corresponding practical problems.
