摘　　要：传统技术在超高层建筑测量中,存在测量精度较低的问题,且整体测量模型的稳定性较差。针对该情况,本文提出一种基于无人航飞的超高层建筑三维点云校准测量方法。布设无人机(UAV)航测控制网,在获取清晰的超高层建筑图像的基础上进行模型计算,提升测量有效性,减少模型三维误差,确保测量数据处于较高的收敛程度中,完善建模测图以及数据处理机制,由此提高测量精度。根据实验结果分析可知,该测量方法能够有效减少测量误差,整体测量精度提升了24%,表明该方法能够有效完成无人机航测技术在超高层建筑测量中的应用。Traditional technology has the problem of low measurement accuracy in the measurement of super high-rise buildings,and the overall stability of the measurement model is poor.Therefore,this paper proposed a three-dimensional(3D)point cloud calibration and measurement method for super high-rise buildings based on unmanned aerial vehicle(UAV)flight to address these issues.The paper set up a UAV survey control network and conducted model calculations based on obtained clear images of super high-rise buildings,improving measurement effectiveness,reducing 3D errors of the model,and ensuring that measurement data was at a high level of convergence.It improved modeling,mapping,and data processing mechanisms,thus enhancing measurement accuracy.According to the experimental results,this measurement method can effectively reduce measurement errors and improve overall measurement accuracy by 24%,indicating that the method can effectively complete the application of UAV survey technology in the measurement of super high-rise buildings.
