中文摘要：

当机场障碍物较多时,飞行性能工程师往往会出现计算工作量繁重和工作效率低的问题。为了解决这一问题,我们依次建立了机场障碍物数据库、设计了障碍物的坐标转换方法、阐述了机场重要障碍物的评估确定与输出方法,编写了机场重要障碍物的三维可视化输出语言,最终设计出了一款机场重要障碍物评估软件,利用它来评估机场障碍物,并且对机场周边重要障碍物进行三维可视化显示。

英文摘要：

When there are too much obstacle near the aerodrome,the aircraft performance engineer will have to face heavier workload and low work efficiency. In order to solve this problem, we establish the aerodrome obstacle database; and design a method about transforming of the coordinates.This paper describes the evaluation and output method of the important obstacles in the airport.The three-dimemional visual output computer language of the important obstacles in the airport was prepared. Finally, an airport important obstacle assessment software is designed,the ability of software can realize the function we need. We can use it to assess the aerodrome obstacle, meanwhile ouput the result by 3D visualization.
