在欧洲遗产管理的背景下，考古实践面临着记录和复制迁地保存遗址的巨大挑战。作为《瓦莱塔条约》的结果，作为过去人类活动主要来源的出土建筑的存档图像和图纸数量呈指数级增长。然而，与便携式遗骸不同的是，它们未来的研究和修订受到记录数据的二维特征的影响，这使得它们未来的重建难以进行新的研究或公开传播。应该追求更逼真的三维（3D）记录和存档方式。在本文中，使用PhotoScan软件包（Agisoft LCC）在基于计算机视觉的方法中检查了考古特征的3D注册的可能性。事实证明，与传统的文件编制方法相比，它是一种科学和经济有效的改进。该方法的优点是准确性高、简单明了。从三维模型中提取正射影像或数字地形模型，可以将详细准确的信息整合到数字考古挖掘计划中。3D表面建模的视觉特性提供了增强的输出可能性，为未来的研究提供了更好的原位结构文档，并提高了公众对考古遗产的参与和认识。(C) 2012 Elsevier Ltd.版权所有。
Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage.
