摘　　要：为更全面地掌握智慧城市环境动态变化情况,研究基于虚拟现实技术的智慧城市环境动态变化自动化模拟系统。利用GIS数据层获取智慧城市环境空间数据,输入三维CA智慧城市环境动态变化模型,生成智慧城市的动态变化结果;将结果存储在VR场景数据库中,构建逼真的智慧城市环境动态变化虚拟场景,用户可以与虚拟场景交互,通过漫游与交互设计展示智慧城市环境变化。实验结果显示:场景立体度高、画面逼真,加载时间快且流畅,能模拟不同年份的建筑和土地变化,应用效果卓越。In order to grasp the dynamic change of smart city environment more comprehensively,the automatic simulation system of smart city environment dynamic change based on virtual reality technology is studied.Utilize the GIS data layer to obtain spatial data of the smart city environment,input the 3D CA smart city environment dynamic change model,and generate the dynamic change results of the smart city.Store the results in the VR scene database to construct a realistic virtual scene of dynamic changes in the smart city environment.Users can interact with virtual scenes and showcase changes in the smart city environment through roaming and interactive design.The experimental results show that the scene has high stereoscopic accuracy,realistic visuals,fast and smooth loading time,and can simulate changes in buildings and land in different years,with excellent application effects.
