人工建模技术在地铁三维图中的应用

三维示意图的三维模型仿真度可超过90%,各种城市实景和信息由实地采集所得,并按照卫星定位和国家测绘相关标准与要求绘制,表达位置精准,以45°视角俯瞰城市,使乘客能轻易地通过辨认自己熟悉的建筑物来判断方向,从而强化地铁出口位置和周边信息的导向功能。以郑州市轨道交通5号线32个站点的三维示意图工程为例,简述了人工建模技术在郑州地铁交通服务中的应用情况,并对人工建模的流程和关键技术等进行了研究。

Research on Application of Artificial Modeling Technology in 3D Map of Subway

The 3D model of the 3D sketch map has a simulation degree of more than 90%and an image element of more than 250 dpi.All kinds of city scenes and information are collected on the spot and drawn according to the relevant standards and requirements of satellite positioning and national surveying and mapping.The location of the map is precise.The content of the map is not less than 500 meters in the radius of the subway station as the central point,and is overlooked from a 45°angle of view city,so that passengers can easily identify familiar buildings to determine the direction,thereby strengthening the subway exit location and surrounding information guidance function.In this paper,taking 32 stations of Zhengzhou subway line 5 for example,we described the application of artificial modeling technology in Zhengzhou subway transportation service,and studied process and key technology of artificial modeling.
