三维激光扫描支持下电视塔变形监测试验研究

Experiment Research on Deformation Monitoring of Television Tower by Three-dimensional Laser Scanning

三维激光扫描仪目前已成为空间数据获取的一种技术手段。针对电视塔在运营中的形变情况,使用三维激光扫描仪定期对电视塔的移动变形进行观测,并通过对电视塔的形变监测数据采集、内业处理、分析与预报,可以较快地获得空间位置的相对变化,并与传统的测量方法进行精度对比分析,为电视塔的安全运营提供了技术保障和决策支持,同时也为焦作市其他高大建筑物的变形监测提供了经验。

At present,it is one of technical way to obtain spatial data＇s by three-dimension laser scanner.Aimed at deformation situation in motion of television tower,deformation monitoring is implemented by three-dimensional laser scanner at fixed period,relying on deformation monitoring data＇s are collected,processed,analyzed and predicted,then spatial location relative change of television tower is obtained quickly.And the precision compared and analyzed between three-dimensional laser scanning and traditional surveying methods,the expected effect is received.Technology secure and policy decision supporting are provided for security running of television tower,also experience gained by deformation monitoring of television tower is afforded for others high structures in Jiaozuo.
