基于无控倾斜摄影的实景三维建模生产研究

Research on Real 3D Modeling Production Based on Oblique Photography of Image without Ground Control Points

随着倾斜摄影测量技术的发展,利用多旋翼无人机搭载倾斜航摄系统获取地面建筑物影像,进而使用PhotoScan、街景工厂等处理软件,将地面全要素制作成三维模型,这种技术逐渐替代了传统手工三维建模,成为快速构建城市三维模型的新选择。本文针对多旋翼无人机获取的倾斜影像存在旋偏角较大的特点,基于无控数据的空三重建方面进行了研究,制作出符合规范的空三数据,选取最适合旋翼无人机倾斜影像的生产方法,形成基于无控倾斜摄影数据的实景三维生产解决方案。

With the development of oblique photograph,using the UAV to carry the oblique aerial photography system to obtain the image of ground buildings,then using Photo Scan,Street Factory or other processing software,the ground elements are made into the 3D model. This technique gradually replaces the traditional manual 3D modeling and becomes a new choice for the rapid construction of the 3D model of the city. In this paper,the tilt angle of the tilt image obtained by the rotor UAV is larger. The research is carried out on the aerial triangulation reconstruction based on uncontrolled data to make up the standard aerial triangulation data. Select the most suitable method for the production of tilt images of UAV,and form a real 3D production solution based on uncontrolled tilt photography data.
