基于倾斜航空影像的城市生态三维重建研究

Research on reconstruction of 3D urban ecology based on oblique aerial images

针对当前城市建筑物三维模型构建的需要,本文提出一种利用非量测型相机获取的倾斜航空影像来实现高精度空中三角测量和城市三维重建的技术路线。一方面通过倾斜相机重叠影像自动匹配的自检校来支持高精度空中三角测量;另一方面,通过检校的4个倾斜相机,能够在一次飞行中获得4个方向的建筑物侧面影像,为城市景观的三维表达、精细建模和可视化提供一种新的、快捷的技术方案。

To meet the needs of the current city building 3D model construction,this paper puts forward a kind of using non metric camera to obtain oblique aerial images technical route to realize high precision aerial triangulation and urban 3D reconstruction. On the one hand,high precision aerial triangulation was supported by the camera image overlap automatic matching of self- calibration; On the other hand,building profile images could be acquired at one flight from four oblique cameras.This paper provides a new and high- efficient technical scheme for the 3D expression of the urban landscape.
