摘　　要：针对传统变形监测手段面对高大的塔式建筑物时观测困难的问题,以云南大学呈贡校区塔式建筑物为研究对象,采用Leica P40地面三维激光扫描仪对其进行两期三维点云数据采集,经点云数据绝对定向、拼接与融合等数据处理后,构建两期点云数据模型,对两期数据进行模型拟合与点位差异分析。结果表明:该塔式建筑物整体未发生明显水平位移与沉降,墙体表面存在脱落可能。该结论表明基于地面三维激光扫描仪的高塔建筑物形变分析可行。Aiming at the problem of difficulty in observation of traditional deformation monitoring methods facing tall tower buildings.Taking the tower buildings on the Chenggong campus of Yunnan University as the research object,the Leica P40 ground 3 D laser scanner was used to collect two phases of 3 D point cloud data.After data processing such as absolute orientation,splicing and fusion of the point cloud data,two Periodic point cloud data model.Model fitting and point difference analysis of the two periods of data show that there is no obvious horizontal displacement and settlement of the tower building as a whole,and the wall surface may fall off.This conclusion shows that the deformation analysis of high tower buildings based on the ground 3 D laser scanner is feasible.
