多时相三维激光扫描技术在考古发掘过程中的应用——以江苏孔塘遗址为例

摘要

3D laser scanning technology has been increasingly applied in heritage preservation and ar-chaeological excavations for its advantages of efficiency,accuracy,and keeping the relics intact.The excava-tion of the Kongtang site located in Jurong, Jiangsu province has used the 3D laser scanning technology to collect spatial data of different types of heritage remainsthrough successional scanning and recording the en-tire working process.The collected multi-temporary point cloud data are processed through steps of registra-tion,segmentation,and interpolation to reconstruct the three-dimensional scenes of the site.These sceness-how the space-time relationship of the site at different stages and provide data support for later investiga-tions.%三维激光扫描技术凭借快速、准确、无需接触文物表面等优势,已被越来越多地应用于文物保护和考古发掘工作中.江苏句容孔塘遗址在发掘过程中运用三维激光扫描技术不断跟进扫描,全面真实记录发掘过程中的各类遗迹的空间数据.在顾及遗存特征的前提下,对多时相墓葬点云数据进行了空间匹配、分割和缺失数据拟合等后期处理,重建遗址三维场景,直观展示多期遗存的时空关系,为后期考古研究推理提供了数据支持.
