摘　　要：出于提高复杂不规则采空区三维建模效率以及精确度的目的,通过改进多源异构数据融合进行三维建模的方法,结合实际研究案例及关键技术,构建复杂不规则采空区三维建模框架,由地面激光雷达以及无人机航测进行数据采集并得到对应点云,对点云去噪处理并结合改进快速点特征直方图以及迭代最近点方式实现。通过结合实际案例进行模拟仿真试验,得出改进的多源异构数据融合防范进行复杂不规则采空区的三维建模时,点云配准时间大幅缩短,点云配准误差更小的结论。In order to improve the efficiency and accuracy of 3D modeling of complex irregular goafs,the 3D modeling framework of complex irregular goafs is constructed by improving the method of multi-source heterogeneous data fusion for 3D modeling,combined with actual research cases and key technologies,and the corresponding point clouds are obtained by ground lidar and UAV aerial survey.By carrying out simulation experiments in combination with actual cases,it is concluded that the point cloud registration time is greatly shortened and the point cloud registration error is smaller when the improved multi-source heterogeneous data fusion prevents the three-dimensional modeling of complex irregular goafs.
