摘　　要：倾斜摄影测量按照相机镜头的个数可分为五镜头相机、双镜头摄像机及单镜头相机等。在城市实景三维建模中,单镜头无人机由于外业影像采集视角有限,模型精度整体偏低,而五镜头无人机载荷过大,测量成本较高,一般不适用于小范围场景建模。将双镜头无人机应用于城市精细化实景建模中,从多角度与五镜头、单镜头进行综合对比。研究结果表明,双镜头倾斜侧影测量兼顾了模型质量及成本优势,在城市实景建模中具有较好的应用前景。According to the number of camera lenses,tilt photogrammetry can be mainly divided into five-lens cameras,dual-lens cameras and single-lens cameras,etc.In urban real scene 3D modeling,the model accuracy of single-lens UAV is generally low due to the limited field image acquisition perspective,while the five-lens UAV is generally not suitable for small-range scene modeling due to excessive load and high measurement cost.Dual-lens UAV is applied to urban fine reality modeling,and comprehensive comparison is made with five and single lens from multiple angles.The research results show that dual-lens oblique profile measurement takes the advantages of model quality and cost into account,and has a good application prospect in urban reality modeling.
