摘要
面向考古遗址三维重建,以安徽凌家滩遗址为例,提出了多源数据融合方法和基于融合结果的古地层三维建模方法.根据无人机航拍数据、大范围钻探数据、基础地理数据、田野考古图及文本资料,着重研究解决这些多源异构时空数据在空间基准、时空尺度和数据结构等方面的差异问题,进而构建了该遗址古地表三维模型.并在此模型基础上,初步探讨了面向考古遗址时空分析的地理空间统计、空间关系和最优路径分析等应用研究方法.实践证明,本文提出的方法为考古研究提供了直观科学的可视化平台,有助于进一步分析大范围遗址中各类遗迹的时空关系,为推演古人类的生存环境和历史发展规律提供依据.本研究深化了地理学与考古学的交叉应用,为数字考古提供新的思路,也拓展了历史地理研究新方向.
A multi-source data fusion method and a 3 D modeling method for paleostratigraphy(by focusing on solving the difference of the multi-source data in the space criterion,scale,data structure and so on.)based on fusion results were proposed in this paper. By taking Lingjiatan Site as a study case,the 3 D model of the ancient surface was constructed based on UAV aerial data,extensive drilling data,basic geographic data,field archaeological maps,text data and so on. What’s more,the application research method of spatial statistics,spatial relationship and optimal path analysis based on the constructed model were also discussed preliminarily in the paper,and the experimental results were in line with the expectations of archaeologists. It had proved that the method proposed in this paper provided an intuitive and scientific visualization platform for archaeological research,and was helpful for further analysis of spatio-temporal relationship of various relics in large-scale sites. Besides,it could help archaeologists understand the living environment,customs and productivity development level of the ancients,and provide a basis for the study of historical development and environmental change. More importantly,this study deepens the cross-application of geography and archaeology,not only solves the practical problems in digital archaeology and promotes the process of archaeological digitization and standardization,but also brings new vitality into the geography subject,and expands the new direction of historical and geographical research.
