应用三维激光扫描技术监测高层建筑整体变形

3d laser scanning technology is applied to monitor the overall deformation of high-rise buildings

三维激光扫描技术被大量应用于各种事故调查、历史古迹恢复、工程测量等领域中,应用于高层建筑整体变形监测却很少。文章分析了三维激光扫描系统的原理,研究了变形监测中三维激光扫描技术的应用现状及高层建筑整体变形监测中三维激光扫描系统的常见误差。其次,选择3维激光扫描仪来对某采空区上方三个高层建筑进行整体变形监测,利用三维激光扫描仪有效提取房屋特征点,获得其移动变形情况。实测表明,所测得的房屋移动变形值精度较高,完全符合地表沉陷监测的相应要求。

Three-dimensional laser scanning technology has been widely used in various accident investigation,historic site restoration,engineering surveying and other fields,and it is seldom used in the overall deformation monitoring of high-rise buildings.Through the analysis of the principle of3d laser scanning system,and studies the deformation monitoring of the present situation of the application of3d laser scanning technology and high-rise buildings in the whole deformation monitoring a common error of3d laser scanning system.It choose three-dimensional laser scan to perform overall deformation monitoring on that three high-rise buildings above a certain hollow area,and effectively draws the feature point of the house through the3d laser scanner to obtain the deformation situation of the moving house.The measured results show that the measured value of the moving deformation of the house is high,which is fully consistent with the corresponding requirements of surface subsidence monitoring.
