摘要
纸质文物粗化程度是纸质文物保存情况质量检测的重要指标。为充分提升当前纸质文物粗化程度的检测效率和检测精度,以空气耦合超声技术为基础构建了一种纸质文物粗化程度计算机检测系统。该系统包含了超声发射单元等硬件模块及特征提取等软件模块。以某图书馆内典藏的纸质文物为对象,对该系统的工作性能进行试验分析。结果表明,该系统可以对紫外加速老化、自然老化的宣纸,自然老化的报纸等进行粗化程度检测,且检测精度较高。
The degree of roughening of paper cultural relics is an important indicator for the quality inspection of the preservation condition of paper cultural relics.To fully enhance the detection efficiency and accuracy of the roughening degree of current paperbased cultural relics,a computer detection system for the roughening degree of paper-based cultural relics was constructed based on air-coupled ultrasonic technology.This system includes hardware modules such as ultrasonic emission units and software modules such as feature extraction.Taking the paper-based cultural relics in a certain library as the objects,the working performance of the system was experimentally analyzed.The results show that the system can detect the coarsening degree of Xuan paper with accelerated ultraviolet aging and natural aging,as well as naturally aged newspapers,etc.,and the detection accuracy is relatively high.
