Data collection was carried out in two cotton crop plots located in the district of Lambayeque, province of Lambayeque, Lambayeque region, Peru (6°40′20″ S, 79°53′17″ W). A total of 370 original images were captured in JPG format at a resolution of 640 × 640 pixels, using a Samsung A12 device mounted on a 2.5 m-high structure.
Out of these, 100 images were selected for manual annotation using LabelImg (v1.8.6), resulting in 3062 YOLO-format annotations corresponding to the class “cotton”.
Subsequently, data augmentation techniques were applied (progressive rotations ranging from −5° to +5°), which expanded the dataset to 2186 images with a total of 70,348 annotated cotton fruits.
This dataset is intended to support research in computer vision, object detection, and agricultural applications based on artificial intelligence.

数据采集工作于秘鲁兰巴耶克大区兰巴耶克省兰巴耶克区的两块棉花种植地块开展，采集点位地理坐标为南纬6°40′20″、西经79°53′17″。研究采用搭载于2.5米高支架上的三星A12（Samsung A12）移动设备，共采集得到370张分辨率为640×640像素的JPG格式原始图像。
从中选取100张图像，使用LabelImg（v1.8.6）工具开展人工标注，最终生成3062条对应“棉花”类别的YOLO格式标注数据。
随后通过数据增强技术对数据集进行扩充：采用范围为-5°至+5°的渐进式旋转操作，最终将数据集规模扩展至2186张图像，总计包含70348个标注的棉花果实样本。
本数据集旨在为计算机视觉、目标检测以及基于人工智能的农业应用相关研究提供支撑。
