AI总结:

针对精准农业无人机扫描因“错失恐惧”采用均匀策略导致效率低的问题,提出名为OverFOMO的主动感知路径规划方法,依据作物杂草检测数量与置信度调速,计算量与农田规模无关,经仿实评估性能优于现有方法且已开源。

摘要:

本文研究了应用于精准农业场景的无人机信息路径规划问题。首先,我们观察到对数据的“错失恐惧”会导致在整个农田采用均匀、保守的扫描策略。因此,采用非均匀扫描方法能够减少在实际价值极低或可忽略的区域的时间消耗,同时确保在信息密集区域实现更高的精度。梳理现有的信息路径规划方法后,我们发现部分方法计算需求极高,另一些则需要在理想世界模拟器上进行训练。为解决上述问题,我们提出了一种主动感知覆盖路径规划方法,名为OverFOMO,该方法根据识别出的类别(即作物和杂草)的相对数量以及此类检测的置信度来调节无人机的飞行速度。为识别这些目标,研究部署了一个鲁棒的深度学习分割模型。所提算法的计算需求与农田规模无关,因此能够非常简便地应用于现代无人机。我们通过结合真实无人机任务数据与AirSim模拟器高保真动力学特性的仿实流程对该算法进行了评估,结果表明其性能优于此类任务的现有最优方法。该算法及评估流程的开源实现可在以下地址获取:https://github.com/emmarapt/OverFOMO。

英文摘要:

This paper deals with the problem of informative path planning for a UAV deployed for precision agriculture applications. First, we observe that the ``fear of missing out'' data lead to uniform, conservative scanning policies over the whole agricultural field. Consequently, employing a non-uniform scanning approach can mitigate the expenditure of time in areas with minimal or negligible real value, while ensuring heightened precision in information-dense regions. Turning to the available informative path planning methodologies, we discern that certain methods entail intensive computational requirements, while others necessitate training on an ideal world simulator. To address the aforementioned issues, we propose an active sensing coverage path planning approach, named OverFOMO, that regulates the speed of the UAV in accordance with both the relative quantity of the identified classes, i.e. crops and weeds, and the confidence level of such detections. To identify these instances, a robust Deep Learning segmentation model is deployed. The computational needs of the proposed algorithm are independent of the size of the agricultural field, rendering its applicability on modern UAVs quite straightforward. The proposed algorithm was evaluated with a simu-realistic pipeline, combining data from real UAV missions and the high-fidelity dynamics of AirSim simulator, showcasing its performance improvements over the established state of affairs for this type of missions. An open-source implementation of the algorithm and the evaluation pipeline is also available: \url{https://github.com/emmarapt/OverFOMO}.
