This project will establish two Reflectance Transformation Imaging (RTI) systems for use in the recording, analysis and dissemination of ancient written artefacts and archaeological material. RTI uses images captured via digital cameras and high speed video to produce detailed models of surfaces. These can then be visualised in a way similar to interaction with the physical object. Different kinds of processing enable details to be highlighted.The project will design systems incorporating all current best practice in the field. They will be piloted on a range of ancient written materials and on other archaeological materials, in order to develop systems and workflows suitable for rolling out across the cultural heritage sector. The project will also produce freely available blueprints and specifications for the systems, free software, and tutorial materials that will enable rapid takeup of the technology by experts and the interested public. The technology has significant industrial, commercial and public potential.In the field of ancient document studies, the RTI systems will stimulate new research by enabling the capture of important collections that are often dispersed and difficult to access. These objects are often very hard to read and RTI will help with their interpretation. In addition, the ability to combine related documents from different collections and to link them to textual data will have a direct impact on research. Virtual access will limit the need for physical interaction with these frequently fragile, priceless objects.In the broader field of archaeology RTI enables the detailed analysis of objects where surface texture is of particular importance, such as recording Roman brick stamps, measuring the deterioration of delicate textiles or wall paintings, and analysing lithics or bones.The systems will be embedded in two established communities. First, the Oxford Centre for the Study of Ancient Documents. CSAD has proven its value across the broad field of ancient texts and written artefact studies. The focus of the CSAD's research on a wide range of ink-written, incised and inscribed texts addresses technical problems of digital imaging and signal-processing. The effectiveness of these has been demonstrated in a number of published studies, but work remains to be done on turning them into flexible instruments. The RTI systems will provide this flexibility across datasets and disciplines, drawing directly from CSAD's experience.The second community is the Archaeological Computing Research Group at the University of Southampton. This group has for twenty years been at the forefront of archaeological computing teaching and research, with strong links across the academic, commercial, public and third sectors. One particular strength of the ACRG is in the capture and analysis of digital datasets from archaeological materials. This includes work developing and integrating RTI, laser scanning, and digital photogrammetry. The project members have recently submitted for publication a major study of archaeological applications of RTI in areas such as conservation, surface analysis, visualisation, public dissemination and archiving. The ACRG benefits from strong links with the School of Electronics and Computer Science at Southampton. Their involvement brings a long history in imaging approaches to cultural heritage materials, with a focus on art, and in the necessary cutting-edge electronic research core to this project. The success of these teams is further supported by the involvement of Tom Malzbender from Hewlett Packard Labs as an advisor, ensuring that the two systems are and remain at the forefront of research and value in this area. The systems produced will be integrated into existing CSAD digital frameworks designed to improve access and analysis of the data studied. Partnership with the Archaeology Data Service will similarly safeguard the future of the archaeological data produced.

该项目将建立两个反射率转换成像（RTI）系统，用于在古代书面人工制品和考古材料的记录，分析和传播中使用。 RTI使用通过数码相机和高速视频捕获的图像来生成详细的表面模型。然后可以以类似于与物理对象的相互作用的方式进行可视化。各种处理可以突出显示细节。该项目将设计结合现场所有最佳实践的系统。为了开发适合在整个文化遗产部门推出的系统和工作流程，它们将在一系列古老的书面材料和其他考古材料上进行驾驶。该项目还将为系统，自由软件和教程材料提供免费可用的蓝图和规格，以使专家和感兴趣的公众可以快速采用该技术。该技术具有重要的工业，商业和公共潜力。在古代文档研究的领域，RTI系统将通过捕获经常被分散且难以获取的重要收藏来刺激新研究。这些对象通常很难阅读，RTI将有助于其解释。此外，将不同集合中相关文档并将其链接到文本数据的能力将对研究产生直接影响。虚拟访问将限制与这些经常脆弱的无价物体进行物理互动的需求。在更广泛的考古学领域RTI可以详细分析表面纹理特别重要的物体，例如记录罗马砖邮票，测量详细的纺织品或墙壁绘画，并分析质地或骨骼。首先，牛津大学研究中心。 CSAD证明了其在整个古代文本和书面人工制作研究的广泛领域的价值。 CSAD的研究重点是广泛的墨水写，切割和铭文的文本，涉及数字成像和信号处理的技术问题。在许多已发表的研究中已经证明了这些功能的有效性，但是将它们变成灵活的仪器还有待努力。 RTI系统将直接从CSAD的经验中提供跨数据集和学科的灵活性。第二个社区是南安普敦大学的考古计算研究小组。该小组已经在考古计算教学和研究的最前沿，在学术，商业，公共和第三个领域之间建立了牢固的联系。 ACRG的一种特殊优势是从考古材料捕获和分析数字数据集。这包括开发和集成RTI，激光扫描和数字摄影测量法的工作。该项目成员最近提交了对RTI在保护，表面分析，可视化，公共传播和归档等领域的考古应用的主要研究。 ACRG受益于与南安普敦电子和计算机科学学院的牢固联系。他们的参与为文化遗产材料的成像方法带来了悠久的历史，重点是艺术，以及该项目必要的尖端电子研究核心。这些团队的成功得到了惠普（Hewlett Packard）实验室的汤姆·马尔茨本德（Tom Malzbender）作为顾问的参与，以确保这两个系统在该领域的研究和价值保持最前沿。生产的系统将集成到现有的CSAD数字框架中，旨在改善研究数据的访问和分析。与考古数据服务的合作伙伴关系将同样地保护所产生的考古数据的未来。
