摘　　要：针对机场空侧真实感三维场景建模的需求,提出一种采用机场地图数据库,在OpenFlight API支持下参数化生成机场空侧三维场景模型的方法。首先分析了AMDB数据库架构和数据构造;其次依据AIXM5数据交换标准,设计了针对机场空侧三维场景模型几何数据整合接口;然后提出了机场空侧三维场景模型的特征分类模型,并根据不同的分类设计基于OpenFlight API的场景树生成方法;最后通过实例构建了三维场景模型。该技术能够实现不同时候、天气情况下机场空侧三维场景的快速构建。According to the requirements on photorealistic 3D model of airside area in an airport, a parameter modeling method based on AMDB and OpenFlight API is proposed. Firstly, AMDB framework and data organization are analyzed. Secondly, according to the AIXM5 standards, the integrated geometric data interface for extracting AMDB data is designed. Thirdly, the feature classification model of airside area in an airport is proposed; furthermore, by using OpenFlight API, we generate the photorealistic 3D model in accordance with the classification. Finally, we construct some airport 3D model with the above method. This technology can be used to constructor the airport 3D model automatically according to different seasons and weather condition.
