摘要
三维虚拟现实技术是计算机技术和遥感技术相结合的产物,可以模拟三维世界的真实空间,让人们体验到现实中不能体验的感觉,能更好地与虚拟世界进行交互。将三维虚拟现实技术应用到城市规划系统中,可以更好地辅助规划和决策。本文从利用OSG引擎实现系统主机显示端与虚拟显示端的同步虚拟展示展开探究。实践证明,此方法能较好地体现城市建筑物的特点,具有较高的信息饱和度、较低的归一化均方根误差、较好的可视化效果。
3D virtual reality technology is the product of the combination of computer technology and remote sensing technology,which can simulate the real space of the 3D world,so that people can experience the feeling that can not be experienced in reality,and can better interact with the virtual world.The application of 3D virtual reality technology to urban planning system can better assist planning and decision-making.In this paper,the OSG engine is used to realize the synchronous virtual display between the host display and the virtual display.Practice has proved that this method can better reflect the characteristics of urban buildings,with higher information saturation,lower normalized root-mean-square error and better visualization effect.
