Data for: A practical photogrammetric workflow in the field for the construction of a 3D rock joint surface database

The dataset is the 3D rock joint surface database mentioned in the manuscript, which are point cloud files of 310 samples stored in Stanford Triangle Format (*.ply). All samples are processed into standard raster data sets and have realistic colorful texture, which is convenient for researchers to evaluate the roughness of the rock joint surface from a 2D or 3D perspective. The rock joint surface database can also be extended using 3D printing technology. The artificial rock joint surface samples with real morphological features can be reproduced and tested in the laboratory. We hope the supplementary data can increase the visibility and impact of our work. The compressed package contains samples collected from two sites. Each database contains three folders (point cloud segments: "01 PLY File"; images of rock joint: "02 TIF File"; anisotropic visualization results: "03 Polar Plot" ) and one Excel data for joint surface roughness evaluation.本数据集为本论文手稿中提及的三维岩体节理面数据库，包含310个样本的点云文件，存储格式为斯坦福三角格式（Stanford Triangle Format，*.ply）。所有样本均已处理为标准栅格数据集，并带有逼真的彩色纹理，便于研究人员从二维或三维视角评估岩体节理面的粗糙度。该岩体节理面数据库还可借助3D打印技术进行扩展，可复现带有真实形态特征的人工岩体节理面样本并在实验室中开展相关测试。本团队希望本补充数据集能够提升本研究的可见度与影响力。 该压缩包包含从两个采集站点获取的样本。每个数据库均包含三个文件夹与一个用于节理面粗糙度评估的Excel数据文件：分别为点云片段文件夹「01 PLY File」、岩体节理图像文件夹「02 TIF File」，以及各向异性可视化结果文件夹「03 Polar Plot」。
