【摘要】：近年来随着数字城市(智慧城市)的建设与发展,城市信息化的范围将不断扩大,基于大范围城市三维景观模型的建立将日益受到重视。传统的三维建模技术在面对海量数据时所表现出来的建模周期长、可视化效果差等问题,这些软件难以满足现代城市建模的需求。所以,应数字城市的发展需求,城市级的快速建模将成为建模方法研究的趋势。针对以上的问题,本文首先系统地研究了目前城市三维景观重建中主要的两种建模方法,即地形和地物的建模方法。其次,通过对近几年常用的三维建模软件的研究,分析他们各自的功能模块、平台架构,综合比较,最终选择基于CityEngine的规则化建模方法。然后,根据海量数据建模的需求,阐述了CityEngine在实现城市三维景观快速建模上具有的独特优势,并对其城市建模中关键技术进行分析。最后,选择营口市开发区(鲅鱼圈)的部分街道作为实验对象,应用编写的规则模板,完成该实验区的快速三维景观重建,并将三维模型一键发布至Web Scene实现3D模板浏览、查询,以及上传到ArcGIS Online与他人共享。基于CityEngine规则化建立的模型可以通过调整参数值改变模型的外观,并同步显示,显示建筑的空间范围,还可以基于规则输入统计报告,例如统计建筑物占地面积、总建筑面积以及分析其容积率等。CityEngine规则建立的三维模型可以应用于数字城市、城市规划、建筑、管线、轨道交通、仿真、游戏开发等方面。
[Abstract]:In recent years, with the construction and development of digital city (intelligent city), the scope of urban informatization will be expanded, and the establishment of 3D landscape model based on large-scale city will be paid more and more attention. The traditional 3D modeling technology has many problems such as long modeling period and poor visualization effect in the face of massive data. These software can not meet the needs of modern urban modeling. Therefore, to meet the needs of the development of digital cities, rapid modeling at the city level will become the trend of modeling methods. Aiming at the above problems, this paper first systematically studies two main modeling methods of urban 3D landscape reconstruction, that is, the modeling method of terrain and features. Secondly, through the research of 3D modeling software which is commonly used in recent years, this paper analyzes their respective function modules, platform architecture, comprehensive comparison, and finally chooses the regularized modeling method based on CityEngine. Then, according to the requirement of mass data modeling, this paper expounds the unique advantages of CityEngine in the fast modeling of urban 3D landscape, and analyzes the key technologies in urban modeling. Finally, some streets of Yingkou Development Zone (Bayuquan) are selected as experimental objects. The fast 3D landscape reconstruction of the experimental area is completed by using the rules template, and the 3D model is released to Web Scene to realize 3D template browsing. Query and upload to ArcGIS Online to share with others. The model based on CityEngine regularization can change the appearance of the model by adjusting the parameter value, and display it synchronously, showing the space range of the building, and also entering the statistical report based on the rules, for example, statistics on the size of the building. The 3D model based on the total building area and its volume ratio can be applied to digital city, urban planning, architecture, pipeline, rail transit, simulation, game development and so on.
