摘要
传统建立场地现状三维模型的技术方式存在技术门槛高、周期长、工作量大、精度有限等问题,制约了数字城市技术在景观设计中的应用。随着城市建设对景观设计要求的不断提高,景观设计场地现状条件的不断复杂,如何实现对场地的精细化分析,形成更为直观的景观设计对比方案,从而提高景观设计的精确性和落地性,是信息化技术在景观设计领域中的研究热点。从建立数字城市的技术经验出发,介绍了利用无人机航摄获取地面影像,建立场地三维实景模型的技术,实现了针对场地的三维空间分析以及精细化设计。结果表明,三维实景模型的构建具有快速、直观、精确等优势,在规划设计的各个阶段能够充分发挥作用。
There are a lot of problems in traditional site-situation3D model building technology,such as high technical threshold,long operation period,heavy workload and limited accuracy.These problems constrain the application of digital city technology in the landscape design field.Along with the continually increase requirement of urban development for landscape design and more complexity of the site condition,there appears new research hotspots in landscape design on how to realize the delicate analysis and create more visual landscape design plan for comparison,so as to improve the accuracy and operability of landscape design.This paper has been setting up based on the technology experience of building digital city.It introduces the technology abouthow to obtain the image informationon the surface using unmanned aerial vehicles and build3D real-scene models.Thus,it could realize the3D spatial analysis and fine design specific to the site.The result shows that3D real-time model has many advantages such as fast,visual and accurate,thus it could come into play in all kinds of phases in planning and design.
