【摘要】:在对文物进行预防性保护中,需要对监测点进行定期监测而获得监测数据。由于大多数文物依存环境不允许在监测点处设置监测标记,因此不破坏文物依存环境的重定位技术就显得尤为重要。本文提出了一种基于几何约束的三点重定位方法,借助激光标线仪、激光测距仪等设备,在不需要破坏文物依存环境的情况下,对监测点进行精确的重定位。重定位的理论精度达到了0.1mm。在实验室和敦煌莫高窟的实际实验中证明,我们提出的三点重定位方法重定位精度高、操作简单、易于安置、不破坏文物的依存环境,适用于多种监测环境。
[Abstract]:In the preventive protection of cultural relics, the monitoring points need to be monitored regularly to obtain the monitoring data. Because most cultural relic dependent environments do not allow monitoring marks to be set at monitoring points, it is particularly important not to destroy the repositioning technology of the cultural relic dependent environment. In this paper, a method of three-point repositioning based on geometric constraints is proposed. With the aid of laser marking instrument, laser rangefinder and other equipment, the monitoring points can be accurately relocated without destroying the dependent environment of cultural relics. The theoretical accuracy of repositioning is 0.1 mm. It is proved in the laboratory and in Dunhuang Mogao Grottoes that the three-point repositioning method proposed by us has high accuracy, simple operation, easy placement, and does not destroy the dependent environment of cultural relics, and is suitable for various monitoring environments.
