Abstract

Accurate identification of grapevine trunks and interplant weeds is crucial for the intelligent development of weeding sessions in vineyards. Challenges arise due to the nonuniform planting of wine grapes, obscuration of grapevine trunks by interplant weeds, and variations in trunk characteristics across different growth stages, complicating the accurate segmentation of grapevine trunks and intraplant weeds. This study presents a new identification model that employs an improved Deeplabv3 Plus framework with lightweight Mobilenetv2 as its central network, supplemented by a coordinate attention block to boost feature extraction capabilities. The model was deployed using the robot operating system (ROS) on a crawler robot for field operations. We developed datasets for grapevine trunks and intraplant weeds, and upon training and testing, the model achieved a mean intersection over union (MIoU) of 84.4 % and a pixel accuracy of 92.03 %. Field trials integrating the ROS system demonstrated a grapevine trunk miss detection rate of 3.6 %, a false detection rate of 2.4 %, and a detection speed of 22 frames per second (FPS). The results show that our method effectively balances recognition accuracy and speed, offering valuable technical support for developing intelligent field weeders for wine grape cultivation.

基于改进型 Deeplabv3 Plus 的葡萄树干和植株内杂草分割方法

准确识别葡萄树干和株间杂草对葡萄园智能除草工作的开展至关重要。由于酿酒葡萄种植不均匀、植株间杂草对葡萄树干的遮挡以及不同生长阶段葡萄树干特征的差异，导致葡萄树干和植株间杂草的准确分割变得复杂。本研究提出了一种新的识别模型，该模型采用了改进的 Deeplabv3 Plus 框架，以轻量级 Mobilenetv2 作为中心网络，并辅以坐标注意力块来提高特征提取能力。该模型通过机器人操作系统（ROS）部署在爬行机器人上，用于田间作业。我们开发了葡萄树干和植株内杂草的数据集，经过训练和测试，该模型的平均交集比结合率（MIoU）达到 84.4%，像素准确率达到 92.03%。集成 ROS 系统的实地试验表明，葡萄树干漏检率为 3.6%，误检率为 2.4%，检测速度为每秒 22 帧 (FPS)。结果表明，我们的方法有效地平衡了识别精度和速度，为开发酿酒葡萄种植智能田间除草机提供了宝贵的技术支持。
