Abstract:
Since 1970s, deformation monitoring in engineering has been
concerned widely by the society because it is related to the safety of people’s life
and property. The variety of deformation monitoring and the particularity of
precision requirements make the deformation monitoring means constantly
changing. 3d laser scanner, with its unique advantages, makes the deformation
monitoring efficiency of engineering greatly improved. In this paper, the
principle and error source of 3D laser scanning are introduced, the types and
characteristics of deformation monitoring in engineering are analyzed, and
the application of different 3D laser scanners in deformation monitoring in
engineering is obtained, thus providing guidance and reference for the selection
of appropriate 3D laser scanners in deformation monitoring in engineering.
自20 世纪70 年代起,工程中的变形监测因一直关系着人民生命和财产安全而受到社会的广泛关注。变形监测的种类多样化及精度要求的特殊性,使得变形监测手段在不断变化,三维激光扫描仪以其独有的优势,使得工程的变形监测效率得到了极大提高。本文通过介绍三维激光扫描原理及误差来源,分析工程中的变形监测类型与特点,得出工程中不同三维激光扫描仪在变形监测中的应用,从而起到对工程的变形监测中选择合适的三维激光扫描仪有指导借鉴作用。
