Dataset for automated grain size characterization of rock fragments

This is the official dataset of "Automated grain size characterization and gradation evaluation of rock fragments for dam construction using close-range UAV photogrammetry," which we have decided to release ahead of our impending research paper publication. UAV images of rock fragments which we used for grain size characterization. It contains a large number of rock fragments photos that are not limited to those used in our paper. Should you need further assistance or have any queries, please don't hesitate to contact us.本数据集为《基于近景无人机摄影测量（close-range UAV photogrammetry）的大坝建设用岩屑自动化颗粒尺寸表征与级配评价》的官方配套数据集，我们已决定在正式研究论文发表前先行发布该数据集。本数据集包含用于岩屑颗粒尺寸表征的无人机影像，所收录的岩屑照片规模较大，且不限于论文中所采用的样本。若您需要进一步协助或有任何疑问，请随时与我们联系。
