单镜头无人机五向与井字飞行倾斜摄影建模对比分析
Comparative Analysis on Modeling of Five Way and Well Shaped Flight Tilt Photography of Single Lens UAV

以单镜头无人机为平台的倾斜摄影在小区域实景三维建模中得到广泛应用，其航线规划存在五向和井字飞行两种方式。为验证两种航线规划方式建模的质量和精度，本文以某消费级无人机为例，对两种航线所生成三维模型进行了对比分析。实验结果表明，采用两种飞行方式的三维建模成果在精度方面均满足制作大比例尺地形图的精度要求。
Tilt photography based on single lens UAV is widely used in small area real scene 3D modeling. Its route planning has two ways: five-way and well shaped flight. In order to verify the quality and accuracy of the two route planning methods, this paper takes a consumer UAV as an example to compare and analyze the three-dimensional models generated by the two routes. The experimental results show that the three-dimensional modeling results of the two flight modes meet the accuracy requirements of making large-scale topographic map in terms of accuracy.
