已有不少文献针对激光扫描在建筑变形测量中的应用进行了研究,但是国家和行业尚无三维激光扫描技术规程出台。本文通过应用调研、扫描仪的标称精度统计分析,以及具有针对性的试验,明确了激光扫描测量建筑变形的作业方法,确立了选用仪器精度、扫描测量的测回数、标靶入射角度等技术指标,为激光扫描技术在建筑变形测量中的工程应用提供了参考依据。 Many literatures have studied the application of laser scanning in the measurement of building deformation, but there is no technical regulation of 3D laser scanning in the country and industry. Through the application of research, the statistical analysis of the nominal accuracy of the scanner, as well as the targeted tests, the method of laser scanning to measure the deformation of the building was clarified, and the techniques such as the accuracy of the selected instruments, the number of measurements of the scanning measurements and the target incident angle were established It provides a reference for the engineering application of laser scanning technology in the measurement of building deformation.
