摘要
目前,数字城市建模主要采用传统三维建模方法,该方法效率较低、投资成本大、真实纹理采集困难,无法满足城市大范围快速建模的需要。针对传统建模方法局限性,提出了利用新的对地观测技术——倾斜摄影技术实现城市三维建模的方法。该方法旨在结合倾斜摄影技术和3ds max软件的优势,实现一个集三维建模、纹理自动获取、纹理映射等功能于一身的高效率的数字城市建模平台,该方法易于在实践生产中推广,具有较好的应用前景。
At present,digital city modeling still uses traditional 3D modeling method.This method has low efficient and large investment cost,and is difficult to obtain real texture,which can not meet the needs of large-scale fast urban modeling.In view of these limitations,this paper proposes a new method of 3D urban modeling using tilt photography technology.This method aims to combine the advantages of tilt photography technology and 3DS Max software to achieve an efficient digital city modeling platform with three-dimensional modeling,automatic texture acquisition,texture mapping and other functions.
