Abstract Modern measuring technologies give the means to perform tasks previously impossible with conventional methods. Their main advantages include reduced time consumption and higher measurement precision. Contemporary displacement and deformation studies of engineering structures often involve application of laser technologies, which are characterised by high precision of measurements. This article presents an analysis of results obtained from measurements of changes in the geometry of an engineering structure in which two complementary measuring technologies were used, i.e. tachymetric measurement with a Leica TDRA6000 laser station and laser scanning with a 3D FARO Focus S150 scanner. The utilised laser station enabled determination of 3D displacements in the local control point network installed on the studied structure as well as transfer of point clouds obtained from laser scans into a uniform coordinate system. The hybrid technology employed and the measurement method used ensured that the accuracy of the determined displacements and deformations of the structural components of the structure was high. The described measurement and result processing technology makes it possible to comprehensively analyse the geometric performance of structures, which consequently leads to the development of more complete conclusions concerning prevention of adverse effects of displacements and deformations in engineering structures.

基于现代激光技术的工程结构位移与变形研究

摘要 现代测量技术提供了执行以前用传统方法无法完成的任务的方法。它们的主要优点包括减少时间消耗和更高的测量精度。当代工程结构的位移和变形研究往往涉及激光技术的应用，其特点是测量精度高。本文介绍了对工程结构几何变化测量结果的分析，其中使用了两种互补的测量技术，即使用 Leica TDRA6000 激光站进行测速测量和使用 3D FARO Focus S150 扫描仪进行激光扫描。所使用的激光站能够确定安装在研究结构上的局部控制点网络中的 3D 位移，以及将从激光扫描获得的点云转移到统一坐标系中。所采用的混合技术和所使用的测量方法确保了所确定的结构构件位移和变形的精度很高。所描述的测量和结果处理技术可以对结构的几何性能进行综合分析，从而得出关于防止工程结构位移和变形的不利影响的更完整的结论。所采用的混合技术和所使用的测量方法确保了所确定的结构构件位移和变形的精度很高。所描述的测量和结果处理技术可以对结构的几何性能进行综合分析，从而得出关于防止工程结构位移和变形的不利影响的更完整的结论。所采用的混合技术和所采用的测量方法确保了所确定的结构构件位移和变形的精度很高。所描述的测量和结果处理技术可以对结构的几何性能进行综合分析，从而得出关于防止工程结构位移和变形的不利影响的更完整的结论。
