基于数字近景摄影测量的文物三维监测技术及其应用

Three-Dimensional Cultural Relic Monitoring Technology Based on Digital Close-Range Photogrammetry and Its Application

文物变形监测是文物结构安全稳定分析与预报的重要方法,目前常用的全站仪、水准仪等监测方法主要是监测文物某些特征点的变化,以此反映文物的变形,其主要缺陷是不能全面准确反映监测目标的变形特征。文章提出基于数字近景摄影测量的方法实现室外大型文物的三维监测技术,创造性地克服了传统点监测方法的缺陷,极大地降低了传统点监测方法的工作量,监测效率成倍提高,并为表面鼓胀凹陷、风化、褪色、剥落、裂缝等变形破坏监测提供全新了的解决思路。

Deformation monitoring of cultural relic is an important method for stability analysis of cultural relic structures. At present, the commonly used monitoring methods such as total station and balance level are mainly to monitor the changes of some characteristic points of cultural relics to reflect the construction. The main defect is that it cannot fully and accurately reflect the deformation characteristics of the monitoring target. This paper proposes a 3D monitoring technology based on digital close-range photogrammetry to realize large-scale outdoor cultural relic, which creatively overcomes the defects of traditional point monitoring methods and greatly reduces the workload. The monitoring efficiency has been doubled, and a new solution to the deformation and damage monitoring of surface cultural relic, weathering, fading, spalling, cracks, etc. is provided.
