Spray Drift Segmentation for Intelligent Spraying System Using 3D Point Cloud Deep Learning Framework

This study proposes a novel spray drift analysis method, based on 3D deep learning, managing and reducing spray drift using a mobile LiDAR method. LiDAR point clouds were trained to classify and segment spraying forms from orchards using the PointNet++ model, which is a 3D deep learning structure. The trained deep learning model represented an accuracy of 96.23%. The spray drift analysis system was demonstrated through its application in intelligent spraying systems. Three control field experiments were performed in a pear orchard to verify the effectiveness of the system. The obtained results confirm the satisfactory performance of 3D deep learning-based spray drift analysis method. It is expected that the proposed system can measure and manage spray drift.
