基于Pictometry倾斜影像的三维城市模型纹理映射

Texture mapping of 3D city model based on Pictometry oblique image

由于倾斜影像的直观性,目前,倾斜航空摄影测量在摄影测量领域再次成为焦点。倾斜影像能显示出地物丰富的三维信息,它们不但被广泛地应用于三维量测和可视化,还被应用于三维城市模型的构建中。Pictometry公司开发一种中幅面数字影像系统用于获取垂直影像和倾斜影像。文中介绍Pictometry公司的中幅面数字影像系统,并提出一种基于Pictometry数字倾斜影像进行三维城市模型纹理映射的方法。

Recently, oblique aerial photogrametry has become the focus again in the field of photogrametry because of the intuitive perception of the oblique image. The oblique image is rich in 3D information like objects on ground, which is widely applied to not only 3D measurement and visualization but 3D city modeling. The Pictometry corporation has developed a middle format digital image system to capture vertical and oblique images. It introduces the Pictometry＇s middle format digital image system briefly and proposes a method for texture mapping of 3D city models based on Pictometry oblique image.
