On development of portable digital holographic speckle pattern interferometry system for remote‐access monitoring and documentation in art conservation

Artworks are delicate objects representative of the most high values of human kind that require constant control over the situation they are in and effective actions to preserve them and deliver them safely to next generations. As such, the non‐destructive or minimally destructive nature of operator–artwork interactions has been considered as essential in this field. The complete diagnosis of the status of the art object signifying a full knowledge of invisible defects and their morphology allows its timely and correct maintenance and ensures its durability. It is herein presented the basic technical information on the development of a portable system termed Digital Holographic Speckle Pattern Interferometry (DHSPI) for the structural diagnosis of works of art. DHSPI has been tested on a variety of conservation problems over the years. It is a completely portable and fully PC driven automated system for the detection and non‐destructive diagnosis of the structural alterations of an artwork, whether they are defects lying on the subsurface or between the layers below it, the fringe number information allows the depth estimation and the complete documentation. The system exploits the benefits of a highly coherent laser beam as essential presupposition for remote on‐field access—that is the main emphasis given here—to immovable/movable art objects. It takes advantage of a CCD camera as photosensitive medium to record the interference of the retro reflected object laser beam from the object under consideration with a twin reference laser beam. The device allows micro projections of the defects on the surface of the object to be detected with a resolution that corresponds to half the wavelength of the laser beam. Local disparities, in relation to the total response of the object, are directly correlated to the detected microdisplacement of object surface as structural defects. Special tailor‐made software allows full control of the system, processing of the data, and extraction of anomalies. Direct visual qualitative observation of the displacement processes is followed as captured in the monitor. A second custom‐made software—not presented in detail here—enables further processing of the results to improve their imaging, quantification, and dimensioning. The final result is a quantitative map of alterations, the coordinates, and the classification of their risks which can be also extracted if further information is necessary. The qualitative or quantitative documentation map can be used as a guide to the conservator for maintenance and restoration work. Further on, the system also allows observation of the object's response to climate changes in order to predict the formation of alterations or the evolution of existing ones providing the only known direct tool for scheduling preservation strategies.     

强度储备法在岩质高边坡稳定性分析中的应用

强度储备法抓住影响边坡稳定因素中最关键最难确定的强度指标,通过研究不同强度参数所对应的破坏区域的演变关系来分析边坡的稳定性和潜存的破坏机理,是切实可行的。受材料及试验水平限制,以往在该方面的研究仅局限于少数数值分析。本文结合具体边坡工程实践探索强度储备法在岩质高边坡稳定性分析中的应用。在边坡稳定性三维非线性有限元分析中用强度储备法求解边坡在各种工况下的稳定安全系数,并在三维地质力学模型试验中用该方法寻求边坡的稳定安全系数及破坏机理获得成功。数值计算与模型试验所得结果相近。研究成果在工程实践中得到成功的应用。表明强度储备法是岩质边坡稳定分析的有效方法。

基于深度学习的野外露头区岩石裂缝识别

针对当前地质考察中的野外露头区岩石裂缝及周围环境较为复杂且数据依赖人工描绘和传统的图像处理算法,其识别效率及准确度低下造成地质考察研究困难这一实际情况,提出一种基于深度学习的露头区岩石裂缝识别算法,从而提高岩石裂缝识别的准确度及效率。该方法基于TensorFlow架构,先将预处理的训练数据集图片进行人工挑选预处理为裂缝和背景2类图片,再将已分类的图片传入已设计完成的卷积神经网络模型进行训练并保存训练模型的参数数据,用已训练的模型数据对预处理的岩石裂缝图片进行识别并记录裂缝位置信息,通过裂缝位置信息对未预处理过的原色岩石裂缝图片进行裂缝定位并显示。实验结果表明所用方法可较高准确度地识别裂缝,为地质考察提供更准确便捷的裂缝识别方法。     

基于深度学习的无人机飞行轨迹及地质勘测研究

为了对无人机的飞行轨迹及地质灾害勘测进行研究,首先基于深度学习、无人机等相关理论,对无人机飞行高度、图像分辨率以及地质勘测所消耗时间三者之间的关系进行分析;其次将卷积神经网络模型应用于地质勘测图像精度研究中;最后引入Sigmoid算法对无人机的飞行轨迹进行分析。结果表明：无人机的飞行高度与图像分辨率成反比、与地质勘测所用时间成正比。在同一高度、不同控制点的情况下,卷积神经网络模型能够缩小数据的点位误差以及高程误差,并且随着控制点的增多,精确度也会越来越高。将Sigmoid算法引入无人机的姿态控制以及速度控制中,能够将姿态控制的误差限制在-0.5~1之间,速度控制误差限制在-0.3~0.3之间,可见不管是卷积神经网络模型还是Sigmoid算法都对无人机的发展具有优化作用。因此,深度学习下飞行轨迹规划以及地质灾害勘测,对无人机的快速发展具有很大的参考意义。     

斜坡下浅埋偏压隧道地层响应的解析解答

针对斜坡下浅埋偏压隧道的开挖问题,考虑重力梯度作用,根据有限元模拟结果对现有解析偏压初始应力场进行修正,通过理论推导给出隧道开挖引发的地层响应解析解。求解采用复变函数法和Laurent级数解法,采用两种荷载释放方式建立隧道开挖边界的应力边界条件。结合地表边界条件求解得到完整的复位势表达,进而得到全域开挖增量应力和位移的理论解答。考虑到实际工程中隧道边界不存在不平衡力影响,采用洞心释放的理论解答分析了斜坡角度对隧道开挖后的地表位移和洞周应力、位移的影响。结果表明:随斜坡角度增大,偏压影响更加显著,地表位移整体向浅埋侧移动,浅埋侧隆起现象越加明显,地表最大沉降量减小,沉降槽整体向深埋侧移动。环向全应力在90°和270°区域出现拉应力极值,并随偏压角度增加向顺时针方向移动。研究成果对浅埋偏压隧道的初步设计具有参考价值。     

Digital heritage interpretation: a conceptual framework

‘Heritage Interpretation’ has always been considered as an effective learning, communication and management tool that increases visitors’ awareness of and empathy to heritage sites or artefacts. Yet the definition of ‘digital heritage interpretation’ is still wide and so far, no significant method and objective are evident within the domain of ‘digital heritage’ theory and discourse. Considering ‘digital heritage interpretation’ as a process rather than as a tool to present or communicate with end-users, this paper presents a critical application of a theoretical construct ascertained from multiple disciplines and explicates four objectives for a comprehensive interpretive process. A conceptual model is proposed and further developed into a conceptual framework with fifteen considerations. This framework is then implemented and tested on an online platform to assess its impact on end-users’ interpretation level. We believe the presented interpretive framework (PrEDiC) will help heritage professionals and media designers to develop interpretive heritage project.
