MultiLeaf-Dim: A Multi-Species Leaf Image Dataset with Dimensions

This dataset contains 1,088 images from 14 distinct plant species, designed for computer vision and digital phenotyping tasks. Featuring both single-leaf and multi-leaf compositions, every image includes a square scale reference and is paired with annotated reference dimensions to support the development of models for taxonomic classification, segmentation, and morphological measurement.本数据集包含来自14种不同植物物种的1088张图像，专为计算机视觉与数字表型分析（digital phenotyping）任务设计。该数据集涵盖单叶与多叶两种构图形式，每张图像均带有方形比例尺参考物，并配套有带标注的参考尺寸数据，可用于支撑物种分类、图像分割以及形态测量相关模型的开发。
