This paper introduces a methodology for tracking displacements in canvas paintings exposed to relative humidity changes. Displacements are measured by means of the 3D digital image correlation method that is followed by a postprocessing of displacement data, which allows the separation of local displacements from global displacement maps. The applicability of this methodology is tested on measurements of a model painting on canvas with introduced defects causing local inhomogeneity. The method allows the evaluation of conservation methods used for repairing canvas supports.
本文介绍了一种用于跟踪暴露于相对湿度变化的帆布油画中位移的方法。位移通过三维数字图像相关方法进行测量，随后对位移数据进行后处理，这使得能够从全局位移图中分离出局部位移。该方法的适用性在一幅带有引入缺陷导致局部不均匀性的帆布模型画上的测量中得到了测试。该方法可用于评估修复帆布支撑物所采用的保护方法。
