针对消费级无人机采用传统航带式影像采集进行倾斜摄影测量效率低以及精细度不够的问题,提出采用环绕式航摄采集像片进行倾斜摄影三维建模.采用正交试验法对环绕航摄所涉及的参数进行优化研究,创建满足 1 ∶ 500 精度要求的非大高差场地的实景三维模型,得到兼顾建模效率和模型精细度的最优参数组合.基于航带式航摄(五架次)与环绕航摄的对比实验结果表明,采用最优参数组合的环绕航摄倾斜摄影三维建模既能保证建模精度又能极大提高建模效率和模型精细度,可应用于非大高差场地实景建模,促进城市信息模型基础平台的建设.
Optimization of surrounding aerial photography parameters for 3D modeling of oblique photography
Aiming at the problems of low efficiency and low precision in oblique photogrammetry of consumer UAV in using traditional aerial photography,a 3D model of oblique photogrammetry based on the surrounding aer-ial photography is proposed.The orthogonal experiment method is used to optimize the parameters involved in the cross surrounding aerial photography.The real 3D model of the site with a non-large elevation difference meeting the accuracy requirement of 1∶500 is created,and the optimal parameter combination considering the modeling ef-ficiency and model fineness is obtained.The experimental results based on the comparison of aerial belt photo-graphing(five sorties)and surrounding photographing show that the 3D modeling of surrounding aerial oblique photographing with the optimal parameter combination can not only ensure the modeling accuracy,but also greatly improve the modeling efficiency and precision.The research results can be applied to the real scene modeling of non-large elevation sites,and promote the construction of the basic platform of urban information model.
