摘要
目前城市建模的方法中利用航空立体像对建模速度较快,自动化程度高,适合大规模城市建模,但对建筑物侧面纹理获取困难,需要人工采集,效率低下。针对这些局限性,本文提出了一种基于倾斜摄影技术与3ds Max插件开发技术实现城市建模的方法,该方法旨在将两者的优势结合,提供一种实用、快捷高效、半自动城市建模方案。结果证明该方法可实现一次量测同时完成三维模型构建和纹理自动映射,并可直接在3ds Max下进行模型修改。
Modeling using aerial stereo pair in city modeling is less time consuming with high degree of automation and is fit for large scale modeling. While it is difficult to get the side textures of the construc tions directly by the method, and needs much labor with low efficiency. Thus a new method that combined the technology of oblique photography with 3ds Max plug in development was proposed to support the 3- dimensional city modeling in the paper, which would provide a practical and efficient means of semiauto- matic city modeling. The result showed that the 3-dimensional modeling and texture auto-mapping could be realized under one measurement, and the model could be modified on 3ds Max platform directly.
