| 摘 要： | 地形可视性分析在军事、电信、旅游等领域有着广泛的应用。各种复杂的、和应用有关的可视性分析大多数采用的是基于视线(LineofSight,LOS)的方法。文章在阐述视线方法的基础上,根据分析对象的不同对地形可视性分析问题进行了分类,并且从数学模型和实验仿真两方面对各种类型的可视性分析的联系和区别进行了研究,在此基础上提出了关于地形可视性分析的统一模型以及对可视性问题解决方法的一些展望。

| Abstract: | The terrain visibility analysis is widely used in military,telecom,touring and so on.All complex and problem related analyses are mainly based on the Line of Sight(LOS) method.In this paper,the classification for terrain visibility analysis is developed according to the difference of objects to be analyzing.Then the relationship and difference among those visibility analysis types are discussed from the math model and experiment result aspects and a unified model for terrain visibility analysis is developed together with some prospect of the method for this problem. |
