Abstract:
Following the development of digital measurement technology in recent years, the information contained in the measurement outcomes have become increasingly rich. However, the traditional graphical representation method based on vector graph needs to be updated. In this study, we use the Beamless Hall of Linggu Temple as an example. Measurements are conducted by using digital techniques, including three-dimensional (3D) laser scanning, close-range photogrammetry, and infrared thermal imaging. The pseudocolours that express spatial information and moisture distribution are calculated and generated through point clouds, which are used to express the land subsidence, wall deformation, moisture distribution, and other effects of the Beamless Hall. Furthermore, combining it with two-dimensional (2D) graphical representation, such as the plan, elevation, and section, damage-related information can be expressed intuitively and efficiently. This method can combine the advantages of graphics and images to provide a comprehensive and intuitive representation of the digital measurement results of brick architecture heritage. It can also provide a reference for surveying similar monuments and buildings of our architectural heritage.
摘要:
随着近年来数字测量技术的发展,测量结果中包含的信息越来越丰富。然而,传统的基于矢量图的图形表示方法需要更新。在这项研究中,我们以灵谷寺的无梁殿为例。测量是通过使用数字技术进行的,包括三维(3D)激光扫描,近景摄影测量,和红外热成像。通过点云计算和生成表达空间信息和水分分布的伪彩色,用来表示地面沉降,墙体变形,水分分布,以及无波束大厅的其他效果。此外,将其与二维(2D)图形表示相结合,比如计划,高程,和部分,与损伤相关的信息可以直观有效地表达。该方法可以结合图形和图像的优点,为砖建筑遗产的数字测量结果提供全面、直观的表示。也可为我国建筑遗产类似古迹和建筑物的测量提供参考。
