摘　　要：针对园林假山逐年沉降问题,需要对其空间位移变化进行精确测量。以往的测量方法是使用非棱镜全站仪对测量目标的空间坐标进行采集,但这种方法采集信息有限,并且效率较低。基于空间精确定位的方法利用三维激光扫描技术可以对建筑物实行非接触、高效率与高密度的扫描,并将其应用于假山信息采集中。详细介绍了点云数据采集、拼接、建模、模型比对的方法与流程,并将其两期扫描的数据成果进行比对分析,结果表明假山出现不同程度的沉降现象,整体变化趋势基本稳定。研究结果以期为相关部门对园林假山的修葺提供依据。In view of the settlement problem of garden rockery year by year,it is necessary to accurately measure its changes.The conventional measurement method was to collect the three-dimensional coordinates of the measured object with non-prism total station,but this method had limited information collection and low efficiency.The method based on precise spatial positioning can use the three-dimensional laser scanning technology to perform non-contact,high-efficiency and high-density scanning of buildings,and apply it to the collection of rockery information.The method and process of point cloud data collection,splicing,modeling,and model comparison were introduced in detail,and the results of two scannings were compared and analyzed.The results show that the rockery has different degrees of settlement,and that the overall change is basically stable.The research results are expected to provide help to the related departments for repairing the garden rockery.
