摘　　要：进入大数据时代以来,知识图谱、人工智能、虚拟仿真等诸多高新技术迅速发展,地球科学的研究方法也在不断与时俱进。相比传统的二维图像和文本信息,三维数字模型能提供更加丰富多样的数据,可以在基础研究和应用领域发挥重要作用。地质露头和三维标本的数字化是三维建模技术在地球科学领域的两类典型案例。文章对数字露头和三维标本数字化的建设现状进行了调研,对现阶段常用数字化技术、数据共享与开发服务方式以及目前具有代表性的数字地质露头与三维标本数据库进行了介绍,并对调研结果进行了总结分析。此外,还归纳了目前存在的一些问题,从数据建设标准规范、建设内容以及功能拓展等方面,对未来发展进行了展望。In the era of big data,the high techniques such as knowledge graph,artificial intelligence and virtual simulation rapidly developed,and as a result the research methods of geosciences are evolving with the times.Compared to the traditional two-dimensional images and texts,three-dimensional digital models can provide more diverse data,and therefore hold enormous potential for both the scientific research and technology fields.The digitization of geological outcrops and specimens are two typical cases of 3D modeling technology in geoscience.This paper investigated the construction of digital outcrop and 3D specimen digitization,introduced the common digitization technologies,data sharing and development services,and the current representative digital geological outcrop and 3D specimen database.The investigation results were summarized and analyzed.Moreover,some problems that exist at present were summarized,and the future development was prospected in terms of data construction standard specification,construction content and function expansion.
