RGB images of sorghum fields gathered by UAV flights

A supplementary datase for the paper Hybrid-AI and model ensembling to exploit UAV-based RGB imagery: Evaluation of sorghum crops nitrogen content. The data set consist of RGB images of sorghum fields gathered by UAV flights and a CSV that contains laboratory measured ground-truth for Nitrogen content.本数据集为论文《Hybrid-AI与模型集成：利用无人机（Unmanned Aerial Vehicle, UAV）RGB影像开展高粱作物氮含量评估》的补充数据集。该数据集包含两类核心数据：一是通过无人机飞行作业采集的高粱田RGB影像；二是存储有实验室实测氮含量真值（ground truth）的逗号分隔值（Comma-Separated Values, CSV）文件。
