摘要
为了解决传统虚拟规划设计存在数据收集不准确、虚拟画面不真实,无法满足景观精准规划标准的问题,在大数据分析下,提出基于三维景观可视化虚拟系统设计。融入建筑外观和道路设计,同时对场景进行动态浏览,并制作真实渲染图以及三维虚拟动画,对场景进行多方位、多角度展示。根据系统结构图,运用虚拟技术突出仿真效果;采用规则网格法完成地形设计,利用局部插值算法对地形表面数字化采样点或等高线数据进行收集,进而对植被进行构造,并转换为规则的网格数据,由此完成三维景观虚拟规划。实验结果表明,该系统具有数据收集准确、虚拟画面真实等特点,能快速完成景观虚拟规划。
Since the traditional design about virtual planning has the problems of inaccurate data collection and unreal virtual image,and can′ t satisfy the precise planning standard of the landscape,a visualization virtual system based on 3 D landscape is put forward by means of big data analysis,which can integrate the architectural appearance and road design,browse the scene dynamically,fabricate the real rendering pictures and three-dimensional virtual animation and perform multi-faceted and multi-angle display of the scene. In the system,the virtual technology is used to highlight the simulation effect according to the system structure,the regular grid method is adopted to accomplish the terrain design,the local interpolation algorithm is used to acquire the digital sampling points and contours line data of the terrain surface to construct the vegetation,and then convert it into the regular grid data,so as to accomplish the three-dimensional landscape virtual planning. The experimental results show that the system has the characteristics of accurate data collection and real virtual picture,and can accomplish the landscape virtual planning quickly.
