摘要
随着无人机的快速发展,利用无人机为平台的倾斜摄影技术在"数字城市"快速三维建模中得到广泛应用。本文以倾斜摄影技术为基础,深入研究了消费级无人机倾斜摄影三维建模生产的可行性,分析总结了其三维建模的总体流程及关键技术。同时在充分考虑了相机检校及机器性能,两个影响因素的基础上,对生产的三维模型精度进行评价。评价得到三维模型的平面精度中误差为0.189 m,高程精度中误差为0.471m,达到《三维地理信息模型数据产品规范》中平面精度中误差不超过0.300m,高程中误差不超过0.500m的要求。最后总结了此技术的优势和局限性,对"数字城市"快速三维建模工作提供一定参考。
With the development of unmanned aerial vehicles, the use of unmanned aerial vehicles as the platform of the tilt photography technology in the “digital city” rapid three-dimensional modeling has been widely used. Based on the oblique photography technology, this paper deeply studies the feasibility of the three-dimensional modeling and production of the portable UAV tilt photography, and summarizes the overall process and key technology of its 3D modeling. At the same time, taking into account the camera calibration and machine performance, the two factors on the basis of the production of three-dimensional model to evaluate the accuracy. The error in the plane accuracy of the 3D model is 0.189 m, and the error in the elevation accuracy is 0.471 m. The error in the plane accuracy of the “3D Geographic Information Model Data Product Specification” is not more than 0.300 m, and the error in the elevation is not more than 0.500 m The Finally, the advantages and limitations of this technology are summarized, which provides a reference for the 3D city modeling work.
