数字化遗产景观:基于三维点云技术的上海豫园大假山空间特征研究

Digital Heritage Landscape: Research on Spatial Character of the Grand Rockery of Yuyuan Garden in Shanghai Based on 3D Point Cloud Technologies

三维点云技术的快速发展为重新认知中国古典园林遗产提供了重要机遇。以遗产景观保护为视角,对上海豫园黄石大假山空间特征进行定量化研究:全面梳理大假山的历史演进与核心特征,集成运用数字化近景摄影测量技术、激光雷达扫描技术和点云可视化技术采集大假山的空间信息,构建数字化三维模型,更正对其空间尺度认知的误差,并以此为基础,对豫园大假山主次分明、浑然一体、峰峦相间、错落有致、蹬道迂回、盘旋曲赴六大空间特征开展定量化的识别与分析,相关成果为进一步研究大假山的遗产价值和保护策略提供了新的视角和工具。

The rapid development of three-dimensional point cloud technologies has provided significant opportunities for reexamining the rockworks in Chinese classical gardens.With a perspective of heritage conservation,the aim of this research was to quantitatively explore the spatial character of the Grand Rockery in Yuyuan Garden in Shanghai.This research has comprehensively examined the evolution and the character of the Grand Rockery.It has integrated digital close-range photogrammetry,light detection and ranging,and point cloud visualization technologies to collect spatial information of the Grand Rockery,and then built digital models to update existing maps.Based on the new data,this research re-identified the spatial character of the Grand Rockery.The outcomes of this research provided innovative perspectives and tools on heritage value research and conservation strategies for the Grand Rockery.
