虽然长期的实验数据表明，航空热像可以揭示地表和地下的广泛考古特征，但技术障碍在很大程度上阻碍了这种前景光明的勘探方法的更广泛使用。然而，最近在热像仪的尖端程度、商用无人机的可靠性以及摄影测量软件包日益强大的能力方面的进展正在彻底改变考古学家收集、处理和分析航空热像的能力。本文概述了航空热像仪在考古学中的理论基础，并讨论了作者为进行成功的调查而开发的一套新兴方法。总结对北美、地中海和近东考古遗址的调查，我们的结果说明了航空热像仪非常有效的一些背景，以及地面覆盖、土壤组成或考古特征的深度和特征构成挑战的情况。此外，我们还重点介绍了滤除植被噪声的新方法，以及使用辐射热成像提高地物可见性的方法。
While a long history of experimental data shows that aerial thermal images can reveal a wide range of both surface and subsurface archaeological features, technological hurdles have largely prevented more widespread use of this promising prospecting method. However, recent advances in the sophistication of thermal cameras, the reliability of commercial drones, and the growing power of photogrammetric software packages are revolutionizing archaeologists' ability to collect, process, and analyze aerial thermal imagery. This paper provides an overview of the theory behind aerial thermography in archaeology, as well as a discussion of an emerging set of methods developed by the authors for undertaking successful surveys. Summarizing investigations at archaeological sites in North America, the Mediterranean, and the Near East, our results illustrate some contexts in which aerial thermography is very effective, as well as cases in which ground cover, soil composition, or the depth and character of archaeological features present challenges. In addition, we highlight novel approaches for filtering out noise caused by vegetation, as well as methods for improving feature visibility using radiometric thermal imagery.
