公路三维可视化设计的实现

The implement of three-dimensional visual design of highway

综合运用计算机数字化手段，即地理信息系统、遥感、航测、网络、多媒雄及虚拟仿真等技术，对公路工程的基础设施进行全方位的数字采集和处理，结合公路CAD技术，使公路设计实现动态、三维的仿真世界。

In order to make highway design to achieve dynamic and three-dimensional simulation world, this paper, combined with highway CAD technology, carries out figures collecting and treating on infrastructure in highway construction by using computer digitalization methods, i.e. geographic information system, remote sensing, aerial survey, network, multimedia and virtual simulation.
