利用IDL与VC++联合构建森林叶面积指数反演系统

The inversion system for leaf area index of forest based on IDL and VC++

以CHRIS多角度数据为数据源,采用IDL语言,运用控件和类技术实现系统框架,设计模型对象管理器组织模型对象,设计数据的各项处理技术,完成叶面积指数(LAI)物理模型的参数反演与经验模型反演技术,实现近真实森林三维场景的显示。结果表明,利用IDL处理多角度遥感数据是一种可行的技术方案,并实现森林叶面积指数信息自动化提取与浏览。

Using the multi-angle data CHRIS and the IDL computer language, the system framework was built by the technology of controls and class, and the manager of model object was designed to organize the model objects, the data was processed by corresponding technology. LAI（Leaf Area Index） was inversed with physical model and empirical model, then the three-dimension scene of forest was displayed. The result shows that it is a feasible technology scheme to process multi-angle data with IDL, to inverse and display the leaf area index of forest.
