Abstract

Many engineering structures require high measurement accuracy. Their displacement and deformation are determined from the results of special measurements. For the measurements to be accurate, a properly constructed and marked survey network is necessary. The long-term stability of survey points can be ensured by marking (installing) them on solid rock or special triangulation pillars. Accurate and repeatable instrument positioning and premarking over the points is ensured by centring plates. Centring plates with eccentric points can be used when a survey involves several instruments. The article presents the results of measurements and computations done using centring plates with eccentric points. The measurements were conducted in a metrology laboratory. The sought points were premarked with prisms and reflective targets. The measuring methods were angular intersection, linear intersection, and linear-angular measurements. We computed coordinates for the measured points, and the results were compared to their known directory values. The results demonstrate that centring plates with eccentric points can be employed in engineering surveys.

带偏心点的改进型定心板用于大地测量的分析

许多工程结构对测量精度要求很高。它们的位移和变形是根据特殊测量的结果确定的。为保证测量的准确性，一个合理构造和标记的测量网是必要的。通过在坚硬的岩石或特殊的三角测量柱上标记(安装)测点，可以保证测点的长期稳定。准确和可重复的仪器定位和预标记点是由定心板保证。带偏心点的定心板可用于涉及多台仪器的测量。本文介绍了偏心点定心板的测量和计算结果。测量是在计量实验室进行的。搜索点用棱镜和反射目标预先标记。测量方法有角交会法、直线交会法和线角交会法。我们计算了测量点的坐标，并将结果与它们已知的目录值进行了比较。结果表明，偏心点定心板在工程测量中是可行的。

期刊介绍： Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences. The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
