公路环境仿真系统中三维地面模型简化

Simplification of 3D terrain models of highway

随着“虚拟现实”技术的进一步发展 ,它在公路管理中将会有较好的应用前景。但由于其需要依赖较为复杂的数字地面模型的支持 ,这必将制约其更为广泛的应用 ,基于这一情况 ,对公路环境仿真系统中三维地面模型的 DTMs模型及 TIN模型的简化技术作了一定的讨论 ,并提出了一些具体的、实用的算法。

With the development of virtual reality technigue,it will be widely applied in the furture.Since it depends on complex terrain model,it has been limited in application.The technology of simplifying 3d terrain model of DTMs and TIN model in Real time Operation Environment Simulation System is discussed,and some constructive ideas are put forward.
