针对单一点云数据在古遗迹数据存档和模型重建过程中存在数据缺失的问题,以柬埔寨吴哥女王宫遗址为例,提出一套完整和高效的数字化记录与重建方案。通过结合地基激光雷达点云与无人机影像视觉点云,可以解决模型重建过程中激光与视觉点云的配准和融合以及模型构建与修补等关键问题,从而获得目标对象的三维模型。在此基础上,进一步提出的模型应用成果场景漫游动画和平立剖面图,能够更好地为吴哥女王宫保护、修复和研究提供静态和动态数据基础。所提方案能够为古遗迹保护过程中的数据采集、数字化存档、数据分析、场景展示和遗迹修复等多方面提供数据基础与技术参考,进一步推动激光雷达在该领域中的应用。

This paper addresses the problem of the lack of single point cloud data for archeological site data archiving and model reconstruction, using the ruins of Banteay Srei in Angkor, Cambodia as a case study, and proposes a complete and efficient digital recording and reconstruction plan. By combining the ground-based lidar point cloud and the UAV-image visual point cloud, the key issues, such as the registration and fusion of the laser and the visual point clouds, and model construction and repair in the model reconstruction process can be solved, and a three-dimensional model of the target object obtained. Based on this, the proposed model application can produce a scene-roaming animation and vertical profile view that can provide an enhanced static and dynamic data basis for the protection, restoration, and research of the Angkor Banteay Srei. The proposed scheme can also provide data foundation and technical reference for data collection, digital archiving, data analysis, scene display, and relic restoration for ancient heritage protection, and further promote the application of the lidar technology to these fields.
