三维建模中的纹理处理

Texture Mapping in Three-dimensional Solid Modeling

纹理是影响三维模型逼真程度的最主要因素 ,当三维模型建立以后 ,需要将纹理映射在DSM上 ,真实地模拟三维景观。在大范围的城市三维建模中 ,纹理处理的工作量非常大 ,因此如何进行纹理处理是城市三维建模中的关键。本文将对城市三维建模中采用航空遥感影像和地面摄影影像进行地表纹理。

Texture is the main factor which affects the reality of 3D modeling.After three dimensional solid modeling is finished,the next ste is to map remote sensing images as texture data on DSM and simulate real 3D lanscape of the city.In creating 3D model of large area,the textre data processing is huge work ,so texture data procesing is the key in creating 3D landscape of the city. In this paper,aerophotoes and close range photogrammetric images are used to create 3D city model,some problems on the earth surface texture,building roof and side texture and others will be discussed thoroughly.
