摘　　要：倾斜摄影技术是一种通过多个相机同时拍摄不同角度照片,从而实现对测场实景三维建模的方法。在整个过程中,由于不同外业影像采集设备的视角不同,使得相机镜头数可能会对实景三维建模的精度产生一定影响。本文主要以常见单镜头、双镜头和五镜头相机为例,建立相同测区实景三维模型,并从模型精度、建模效率以及经济成本等多角度综合对比分析,以期为相关同行相机镜头数的选择和优化摄影流程提供参考。This paper points out that oblique photography is a method of real scene 3D modeling in the survey area by taking pictures from different angles with multiple cameras.In the whole process,due to the different viewing angles of different field image acquisition equipment,the numbers of camera lens may have a certain impact on the accuracy of real scene 3D modeling.This paper mainly takes common single-lens,dual-lens and five-lens cameras as examples,to establish a real scene 3D model in the same survey area,and makes comprehensive comparative analysis from multiple perspectives such as model accuracy,modeling efficiency and economic cost,so as to provide technical reference for the selection of the number of camera lens and optimization of photography process of relevant peers.
