Accurately extracting plant point clouds from complex agricultural environments is essential for high-throughput phenotyping in smart farming.However,existing methods face significant challenges when processing large-scale agricultural point clouds owing to high noise levels,dense spatial distribution,and blurred structural boundaries between plant and non-plant regions.To address these issues,this study proposes PlaneSegNet,a voxel-based semantic segmentation network that incorporates an innovative plane attention module.This module aggregates projection features from the XZ and YZ planes,enhancing the model's ability to detect vertical geometric variations and thereby improving segmentation performance in boundary regions.Extensive experiments across representative agricultural scenarios at multiple scales,including open-field populations,greenhouse cultivation environments,and large-scale rural landscapes,demonstrate that PlaneSegNet significantly outperforms traditional geometry-based approaches and deep-learning models in plant and non-plant separation.By directly generating high-quality plant-only point clouds,PlaneSegNet significantly reduces reliance on manual pre-processing,offering a practical and generalisable solution for automated plant extraction across a wide range of agricultural applications. 展开更多
