消费级无人机倾斜摄影三维建模与测图分析

3D modeling and mapping analysis of oblique photography for consumer UAV

相较于传统航空摄影测量使用单镜头、与地面垂直角度进行测量,倾斜摄影测量在无人机平台上搭载多个传感器(镜头),同时从若干不同角度进行影像采集,获取的信息更丰富、完整。使用单镜头消费级无人机实现倾斜摄影测量,充分利用其操作简便、价格低廉等特点,实现实景三维模型的建立,结果表明,精度符合相关规范要求。

Compared with traditional aerial photogrammetry, which uses single lens and adopts vertical angle to the ground, the tilt photogrammetry carries multiple sensors(lenses) on the UAV platform and collects aerial images from several different angles at the same time, which obtains more abundant and complete information. Using single lens consumer UAV for tilt photogrammetry, and making full use of its characteristics of simple operation and low price, the scene 3 D model is established. The experiment shows that the accuracy meets the requirements of relevant specifications.
