【摘要】:在田野考古领域,考古发掘现场是考古资料获取的主要场所,而探方是考古发掘现场的发掘单元,探方的三维重建对历史回溯、古环境恢复等考古研究具有重要意义。传统的田野考古发掘手段获得的地下考古资料大都是分散的二维图形,不利于遗址、文物时空关系研究和完整的三维复原与展示。随着与3D GIS技术的不断发展成熟,以及在考古工作中应用领域的拓展和应用水平的提高,3D GIS为考古发掘中遗址、文物提供数字化的存储、展示与开发利用,为田野考古遗址重建和三维可视化分析提供了更有效的手段。 为了推动3D GIS在田野考古遗址恢复应用的深度和广度,本文展开了基于垂直剖面数据与水平剖面数据分别建立探方遗址中考古地层及遗迹的三维实体模型研究,并给出了考古地层与遗迹整合为一个完整探方模型的方案,具体进行的研究内容和取得的研究成果如下: (1)对田野考古数据进行分析,包括田野考古数据采集流程、田野考古发掘对象和田野考古发掘图类型,总结了田野考古数据的特点,并在此基础上建立了田野考古探方三维空间数据模型,设计数据结构合理表达该空间数据模型。 (2)基于探方四壁二维剖面数据,提出并实现了基于剖面的考古地层三维建模方法,该方法具体包括四个步骤:考古探方数据预处理、考古探方边界面建模、考古探方地层界面建模、考古地层界面与考古探方边界面缝合成体。 (3)利用有限的遗迹平面图和剖面图,提出基于轮廓线的遗迹三维建模方法,重建遗迹三维形态并利用相关信息确定遗迹在考古地层中的空间位置,继而使用三维空间实体布尔运算完成考古地层与遗迹整合。 最后,基于本文提出的算法,以湖南澧县八十W笔荻鳷1-T21田野考古发掘数据为研究对象,实现了面向田野考古探方三维建模原型系统,验证了本文相关研究成果的有效性与实用性。
[Abstract]:In the field of archaeology, the site of archaeological excavation is the main place for the acquisition of archaeological data, and the exploring side is the excavating unit of the site of archaeological excavation. The three-dimensional reconstruction of the excavation is of great significance to archaeological research such as historical backtracking and restoration of paleoenvironment. Most of the underground archaeological data obtained by traditional field archaeological excavations are scattered two-dimensional graphics, which is not conducive to the study of the space-time relationship of cultural relics and the complete three-dimensional restoration and display. With the development and maturity of 3D GIS technology, and the expansion and improvement of application level in archaeological work, 3D GIS provides digital storage, display and utilization for archaeological excavations. It provides a more effective method for field archaeological site reconstruction and 3D visualization analysis. In order to promote the depth and breadth of 3D GIS application in the restoration of archaeological sites in the field, this paper studies the establishment of three-dimensional solid models of the paleostratigraphy and remains of the site based on vertical profile data and horizontal profile data, respectively. The scheme of integrating archaeological strata and remains into a complete square model is given. The specific research contents and results are as follows: (1) analyzing field archaeological data, including field archaeological data collection process, the main contents of this paper are as follows: (1) analyzing field archaeological data, including the process of collecting field archaeological data. The objects of field archaeological excavation and the types of field archaeological excavations are summarized. Based on this, the three-dimensional spatial data model of field archaeological exploration is established, and the data structure is designed to reasonably express the spatial data model. (2) based on the two dimensional section data of four walls, a 3D modeling method of archaeological strata based on section is proposed and realized. The method includes four steps: preprocessing of archeological exploration data, modeling of archeological boundary surface. Modeling the interface of archeological exploration stratum, suturing the interface of archaeological stratum and the boundary surface of archaeological exploration. (3) using finite trace plan and section, a method of 3D modeling of relic based on contour is put forward, which can reconstruct 3D shape of relic and determine the spatial position of relic in archaeological strata. Then the three-dimensional spatial entity Boolean operation is used to integrate archaeological strata and relics. Finally, based on the algorithm proposed in this paper, to Hunan Lixian 80W pen? Dee? Based on the field archaeological excavation data of 1-T21, a 3D modeling prototype system for field archaeological exploration is implemented, which verifies the validity and practicability of the related research results in this paper.
