摘　　要：为提高塔型构筑物的倾斜测量效率,提出了一种基于三维激光扫描技术的塔形构筑物倾斜变形监测方法。首先详细阐述了利用点云进行倾斜变形信息提取及扫描点位精度分析的方法;然后利用逆向工程软件(Imageware)对采集的点云进行重构,并提取构筑物轴线坐标,进而计算得到构筑物的倾斜值;最后通过全站仪前方交会精度比较实验验证了三维激光扫描技术在塔型构筑物倾斜监测中应用的可靠性。结果表明,运用三维激光扫描技术进行塔型构筑物倾斜监测的结果与传统全站仪前方交会方法测定的结果吻合,该技术在塔型构筑物倾斜监测中具有较高的实用价值。In order to improve the tilt measurement efficiency of the tower construction, this paper presented a tilt monitoring method for the tower construction based on 3D laser scanning technology. Firstly, this paper described the method which using point cloud to extract the tilt deformation information and analyzing the scanning positional accuracy in detail. And then, the paper used Imageware software to reconstruct point cloud, extracted the axis coordinates of constructions, and calculated tilt value. Finally, this paper verified the reliability of this method by comparing the total station forward intersection test.
