【摘要】：在對文物進(jìn)行預(yù)防性保護(hù)中,需要對監(jiān)測點進(jìn)行定期監(jiān)測而獲得監(jiān)測數(shù)據(jù)。由于大多數(shù)文物依存環(huán)境不允許在監(jiān)測點處設(shè)置監(jiān)測標(biāo)記,因此不破壞文物依存環(huán)境的重定位技術(shù)就顯得尤為重要。本文提出了一種基于幾何約束的三點重定位方法,借助激光標(biāo)線儀、激光測距儀等設(shè)備,在不需要破壞文物依存環(huán)境的情況下,對監(jiān)測點進(jìn)行精確的重定位。重定位的理論精度達(dá)到了0.1mm。在實驗室和敦煌莫高窟的實際實驗中證明,我們提出的三點重定位方法重定位精度高、操作簡單、易于安置、不破壞文物的依存環(huán)境,適用于多種監(jiān)測環(huán)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.
