摘要:

针对标准化的宽行矮化密植苹果种植模式的特点,设计一种基于视觉—RTK的自主导航植保机器人自主导航系统。导航任务分为2个部分:行间直行阶段应用U—Net语义分割网络提取边缘线拟合出导航线控制行间植保机器人的航向;行头行尾转弯阶段通过预设RTK全局目标点对植保机器人运动轨迹进行控制,发挥组合导航的优势。结果表明,基于RTK全局规划的平均横向偏差为0.1 m,最大偏差为0.3 m;而基于视觉导航的平均横向偏差为0.5 m,最大偏差为0.9 m。植保机器人导航系统基本满足苹果园自动导航任务的要求,具有一定的可行性。

Abstract:

Aiming at the characteristics of standardized wide‑row dwarfing and densely planted apple planting mode, an autonomous navigation system for plant protection robot based on visual—RTK was designed in this paper. The navigation task was divided into two parts as follows: in the straight line stage, the edge lines extracted by U—Net semantic segmentation network were used to fit the navigation lines for independent navigation between rows. The motion trajectory of plant protection robot was controlled by RTK positioning point in the turning stage of the row head and tail, and the advantages of integrated navigation were exerted respectively. The results showed that the average lateral deviation of the global planning based on RTK was 0.1 m and the maximum deviation was 0.3 m, while the average lateral deviation of the visual navigation was 0.5 m and the maximum deviation was 0.9 m. The plant protection robot navigation system basically met the requirements of the automatic navigation task of the apple orchard and had certain feasibility.
