摘　　要：为了提升无人机倾斜摄影技术辅助三维城市建模的工作效率,引入点阵离群标记算法和机器学习算法,使用计算机辅助技术取代三维城市模型修正工作的人工工作环节,在实际项目现场实测中,该方案在节约工时成本的前提下,大幅度提升了三维城市建模的模型精度。最终认为后期继续优化机器学习模块的数据训练过程,可以进一步实现更高效率的无人机三维城市建模工作。In order to improve the efficiency of 3D city modeling assisted by UAV tilt photography,the lattice outlier labeling algorithm and machine learning algorithm are introduced,and the computer-aided technology is used to replace the manual work of 3D city model correction.In the actual project field test,the scheme greatly saves the man hour cost and the accuracy of 3D city modeling is greatly improved.Finally,it is considered that further strengthening the data training process of machine learning module can further achieve more efficient UAV 3D city modeling.
