3dcap-md: Sample datasets of Agisoft Metashape for generating metadata

In this repository we provide Agisoft Metashape (SfM) projects and the 3D models processed from them with their metadata using the example of a souvenir of a terracotta warrior (sample 1) and a preserved wood sample (sample 2). The metadata was generated with our script for metadata generation. The first example is referenced with coded targets and imported coordinate list. The second example is referenced with coded targets and scales defined in between. For each project there is metadata in the format of a *.json file and a *.ttl file. In the metadata folders there are files with all selected metadata and additionally those where only with a Uri link were exported. We used Agisoft Metashape version 1.8.3 to create this data.本代码仓库提供了Agisoft Metashape（运动恢复结构（Structure from Motion，SfM））处理项目，以及基于此类项目生成的附带元数据的三维模型，本次示例以兵马俑纪念品（样本1）与防腐木材样本（样本2）为例。元数据由我们自研的元数据生成脚本生成。 首个示例采用编码标记点（coded targets）与导入的坐标列表完成空间参考配准；第二个示例则借助编码标记点与标记点间预设的比例尺实现配准。每个项目均附带两种格式的元数据文件：*.json格式与*.ttl（Turtle）格式。元数据文件夹中包含两类文件：一类存储全部选定的元数据，另一类仅导出了统一资源标识符（Uniform Resource Identifier，URI）链接。本次数据生成采用的Agisoft Metashape版本为1.8.3。
