数字田野考古精细化实景三维提取与场景适配数据融合表达研究与实践——以苏州历史遗存考古为例

Research and Practice on Refined Real 3D Extraction and Data Fusion Expression of Scene Adaptation in Digital Field Archaeology

以苏州市田野考古现状为出发点,依托考古对象的营造法式等建造技艺和结构特征,提出了集三维场景多源数据融合及信息化表达,应用于一体的数字考古建设体系。通过采用一种多源、异构、海量的考古数据采集体系,以全局优化点云配准为基础和控制点为约束条件,实现考古对象的多粒度成果精细融合和精细化三维表达,解决当前田野考古中空间数字采集和应用中数据碎片化、集成精度不适配等关键技术问题。通过工程实践,该技术体系能够很好的提升数字考古建设需求,同时,为苏州人类文明探源工程提供重要的技术支撑。

Based on the current situation of field archaeology in Suzhou,rely on construction techniques and structural characteristics such as french style of archaeological objects,this paper presents a digital archaeology construction system that integrates multi-source data fusion and information expression of three-dimensional scenes.By adopting a multi-source,heterogeneous and massive archaeological data collection system,and based on the global optimization point cloud registration and the control point as the constraint condition.It realizes the fine fusion and fine three-dimensional expression of multi-granularity results of archaeological objects,to solve the key technical problems such as data fragmentation and integration accuracy mismatch in current spatial digital acquisition and application in field archaeology.Through engineering practice,the technical system proposed in this paper can well meet the needs of archaeology and digital construction of archaeological objects,and will also play a very important role in studying how to protect cultural heritage more effectively.This technical system can improve the demand of digital archaeological construction,and provide important technical support for the Suzhou human civilization exploration project.
