针对早期光学遥感成像模拟软件的不足,根据该系统的使用要求和软件结构,在Windows开发平台下,提出了基于COM(Component Object Model)的光学遥感成像模拟软件的框架设计。对该系统的逻辑结构进行了研究,分析了各模块之间的调用关系,定义了各组件对象。利用COM组件的工作原理给出了相应组件实现的方法。实际应用表明,由于采用了基于COM软件技术,使光学遥感成像模拟软件大大提高了扩展性和通用性。
Aiming at the shortcomings of the early optical remote sensing imaging simulation software, the frame design of the optical remote sensing imaging simulation software based on COM (Component Object Model) is proposed based on the system requirements and software structure under Windows development platform. The logical structure of the system has been studied, the call relationship between the modules has been analyzed, and the components of each component have been defined. The working principle of COM component is given and the corresponding components are implemented. The practical application shows that the optical remote sensing imaging simulation software greatly improves scalability and versatility due to adopting COM software technology.
