多图像摄影测量正迅速成为一种重要的考古工具，这在很大程度上是由于现成软件的自动化水平不断提高。该技术可以提供显着降低考古调查的成本和提高调查结果，因此对在合同主导的背景下工作的考古学家特别有价值，在许多地区占考古工作的大部分（例如在苏格兰高达80%）。多图像摄影测量软件的最新进展导致了高度自动化的工作流程，并大大减少了产生可接受标准的测量结果所需的技术知识负担。虽然大多数多图像摄影测量调查仍然是在学术背景下进行的，但越来越多的遗产专业人员正在使用该技术，其中许多人并不是摄影测量方面的首要专家。采用这种高度自动化的工作流程在结果的准确性和可靠性方面存在一定的风险，如Remondino等人（2012，52）所述。然而，该技术在快速准确调查和降低成本方面的巨大潜力不容忽视，我们面临的挑战是确保考古学家在合同主导的背景下采用的高度自动化的工作流程是强大和可靠的，并得到指导和知识交流的支持。本文并不打算对该技术的技术方面或其发展进行全面的技术审查，而是重点强调其作为考古从业者在两种主要类型的合同主导的考古工作中应用的实用日常工具的潜力，快速调查和社区参与。该技术的非技术概述，然后通过案例研究说明该技术如何在非学术合同主导和社区参与的背景下成功应用。进行这些调查时，用于调查和数据后处理的预算非常有限，而且时间通常非常有限。在每一个案例研究中，使用多图像摄影测量可以得到更好、更快和更具成本效益的结果。案例研究包括为遗产管理目的委托对铁器时代堡垒进行的调查、对潮间带沉船暴露部分的快速调查，以及由16岁以下儿童对17世纪世纪墓碑进行的社区调查。最后讨论了在合同主导的部门更广泛采用的障碍，有人认为，需要采取协调一致的方法来创建和传播简单可靠的工作流程。(c)2014爱思唯尔有限公司版权所有。
Multi-image photogrammetry is rapidly emerging as an important archaeological tool due in large part to the increasing level of automation in off the shelf software. The technique can offer significant reductions in the cost of archaeological survey and in the enhancement of survey results and is of particular value therefore to archaeologists working in contract-led context, which in many areas accounts for the majority of archaeological work (up to 80% in Scotland for example). Recent advances in multi-image photogrammetric software have resulted in highly automated workflows and significantly reduced the burden of technical knowledge required to produce survey results of an acceptable standard. Although the majority of multi-image photogrammetry surveys are still undertaken in an academic context the technique is increasingly being used by a far wider proportion of heritage professionals, many of whom are not first and foremost specialists in photogrammetry. The adoption of such highly automated workflows presents certain risks with regard to accuracy and reliability of results as noted by Remondino et al. (2012, 52). However the enormous potential of the technique for rapid and accurate survey and for reduced costs cannot be ignored and the challenge we face is to ensure that the highly automated workflows adopted by archaeologists in contract-led contexts are robust and reliable and underpinned by guidance and knowledge exchange. This paper is not intended as a comprehensive technical review of the technical aspects of the technique or of its development but instead focusses on highlighting its potential as a practical everyday tool for archaeological practitioners to apply in two of the main types of contract-led archaeological work, rapid survey and community engagement. A non-technical overview of the technique is given followed by case studies illustrating how the technique has been applied successfully in a non-academic contract-led and community engagement context. These surveys have been undertaken with very limited budgets for both survey and post-processing of data and typically with very limited time frames. In each case study, use of multi-image photogrammetry has allowed for better, faster and more cost-effective results than would otherwise have been possible. Case studies include a survey of an Iron Age fort, a rapid survey of exposed segments of an intertidal wreck, both commissioned for heritage management purposes and a community survey of a 17th century gravestone undertaken by children under the age of 16. Finally the obstacles to wider adoption in the contract-led sector are discussed and it is argued that a concerted approach is required to create and disseminate simple and reliable workflows.
