基于倾斜摄影测量技术的三维建模研究

Research on 3D Modeling Based on Oblique Photogrammetry

针对传统摄影测量视场死角的问题,指出倾斜摄影测量能较好地顾及建筑物侧面纹理信息,为三维模型建立提供了一种高效的方法。本文以郑州某校区为例,借助专业的倾斜摄影三维建模软件,成功构建出该校区的三维模型。通过在模型上进行一系列量测工作,并与实际踏勘数据对比,验证模型的精度。研究显示:在像控点约束的情况下,倾斜摄影测量建模不但能直观反映真实场景中地物分布状况,而且精度完全能满足日常生产需求。

Aiming at the problem of blind angle of conventional photogrammetry,it is pointed out that oblique photo⁃grammetry can better take into account the texture information of building side,which provides an efficient method for the establishment of 3D model.Taking a campus in Zhengzhou as an example,this paper successfully constructed a 3D model of the school district with the help of professional oblique photography 3D modeling software.Through a series of measurements on the model,and compared with the actual survey data,the model accuracy was verified.The research shows that under the condition of image control point constraints,the oblique photogrammetric model⁃ing can not only directly reflect the distribution of ground objects in the real scene,but also fully meet the daily pro⁃duction requirements.
