随着成像光谱技术的发展,成像光谱技术已被越来越多地应用于考古研究中。随着应用的不断深入,在理论和实践上都产生了一些问题。本文从传感器、基本原理、数据处理、光谱知识库的建立、数据解译这几个方面总结了在实践中所遇到的问题,并有的放矢的提出了一些可能的解决途径。最后,从遥感和考古的角度提出了异常信息在地下遗址勘测中的定位。在地下遗址勘测中,成像光谱技术在一定的地表异常特征知识的支持下,可为田野考古科研人员提供参考性信息,缩小地面勘探范围。
With the development of imaging spectroscopy, imaging spectroscopy has been increasingly used in archeological research. With the deepening of applications, some problems have arisen both in theory and in practice. This article summarizes the problems encountered in practice from the aspects of sensor, basic principle, data processing, establishment of spectral knowledge base and data interpretation, and puts forward some possible solutions. Finally, from the perspective of remote sensing and archeology, the paper puts forward the location of anomaly information in underground site survey. In the underground site survey, the imaging spectroscopy technique can provide reference information for researchers in field archeology and reduce the scope of ground exploration with the help of some knowledge of the anomalous surface features.
