基于BIM技术的共享街道景观改造仿真系统设计与实现

Design and implementation of shared street landscape reconstruction simulation system based on BIM technology

共享街道景观项目在设计中,通常采用解析法实现三维图像的构建,但此方法导致各个指标间的关联性不高,建模的效率低下,且图像的质量较低。基于共享街道景观信息模型(BIM)技术能够实现共享街道景观改造仿真系统的设计。BIM中Navisworks能够整合和阅览共享街道的景观项目,提供共享街道景观Navisworks信息的组织形式。借助于CAD建模技术,能够完成大型共享街道景观三维仿真系统的建模。同时,基于Navisworks可视化软件可渲染共享街道三维仿真模型,从而制作出共享街道景观的三维仿真图像。BIM能够提供共享街道景观三维仿真系统的实际方案,结合动态演示功能,更好地掌控共享街道景观三维仿真的具体进展。实践表明,基于BIM技术的共享街道景观三维仿真图像的清晰度更高、系统的耗时更短且性能更优。

In the design of the shared street landscape,analytical method is usually adopted to build 3D image,but it nevertheless leads to low correlation between various indicators,with low modeling efficiency and poor image quality.Therefore,the shared street landscape reconstruction simulation system is designed on the basis of the building information model(BIM)technology.In the BIM,Navisworks is used to integrate and review the shared street landscape projects,and provide the organizational form of Navisworks information for the shared street landscape.The CAD modeling technology is used for the modeling of 3D simulation system of large⁃scale shared street landscape.Meanwhile,Navisworks visualization software is used to render the 3D simulation model of shared street landscape,based on which,the 3D simulation image of shared street landscape is built.The BIM can provide the practical scheme of the 3D simulation system for shared street landscape,and better control the detailed progress of 3D simulation of shared street landscape in combination with the dynamic demonstration function.The practices show that the 3D simulation image of shared street landscape based on BIM technology has higher definition,shorter system time consumption and better performance.
