摘要:

植食性潜叶蝇对蔬菜和园艺植物造成严重的经济损失。为了准确科学防控潜叶蝇,调查人员一般通过目测植物叶片上潜叶蝇为害状的严重度来评估农药施用量。这种人工目测估计法客观性差,精准性低,数据难以追溯。为了客观精准诊断潜叶蝇为害等级,达到科学防控潜叶蝇目的,本文采用AR眼镜相机和AI算法结合的方法,建立了野外智能潜叶蝇为害调查系统。该系统利用穿戴式AR眼镜相机作为潜叶蝇为害叶片图像采集工具,便于调查人员利用双手展开受害叶片,来获得较平整的叶片图像。为了准确计算叶片上潜叶蝇为害区域,本文提出了DeepLab-Leafminer图像分割模型。针对潜叶蝇为害区域形状不规则,DeepLab-LeafminerDeepLabv3+基础上添加了边缘感知模块和Canny损失函数,增强了对潜叶蝇为害状的边缘分割能力。与其他表现优越的图像分割模型相比,DeepLab-Leafminer模型达到了81.23%IoU87.92%F1 score,分割效果出色。根据模型分割出的潜叶蝇为害区域在整个叶片的面积占比计算得到的潜叶蝇为害等级,测试结果表明基于DeepLab-Leafminer的潜叶蝇为害等级诊断准确率为92.4%。我们设计并开发了潜叶蝇为害等级自动诊断APPWeb平台,实现了潜叶蝇为害等级诊断结果的可视化和数据分析。这种基于AR眼镜相机与AI模型DeepLab-Leafminer结合进行潜叶蝇为害等级自动诊断的方法为调查人员提供了高效、便捷、准确和数据可追溯的潜叶蝇为害等级自动诊断工具。此外,我们的方法也可以应用于其它作物叶片病虫为害等级自动诊断。

Abstract:

Agromyzid leafminers cause significant economic losses in both vegetable and horticultural crops, and precise assessments of pesticide needs must be based on the extent of leaf damage. Traditionally, surveyors estimate the damage by visually comparing the proportion of damaged to intact leaf area, a method that lacks objectivity, precision, and reliable data traceability. To address these issues, an advanced survey system that combines augmented reality (AR) glasses with a camera and an artificial intelligence (AI) algorithm was developed in this study to objectively and accurately assess leafminer damage in the field. By wearing AR glasses equipped with a voice-controlled camera, surveyors can easily flatten damaged leaves by hand and capture images for analysis. This method can provide a precise and reliable diagnosis of leafminer damage levels, which in turn supports the implementation of scientifically grounded and targeted pest management strategies. To calculate the leafminer damage level, the DeepLab-Leafminer model was proposed to precisely segment the leafminer-damaged regions and the intact leaf region. The integration of an edge-aware module and a Canny loss function into the DeepLabv3+ model enhanced the DeepLab-Leafminer model's capability to accurately segment the edges of leafminer-damaged regions, which often exhibit irregular shapes. Compared with state-of-the-art segmentation models, the DeepLab-Leafminer model achieved superior segmentation performance with an Intersection over Union (IoU) of 81.23% and an F1 score of 87.92% on leafminer-damaged leaves. The test results revealed a 92.38% diagnosis accuracy of leafminer damage levels based on the DeepLab-Leafminer model. A mobile application and a web platform were developed to assist surveyors in displaying the diagnostic results of leafminer damage levels. This system provides surveyors with an advanced, user-friendly, and accurate tool for assessing agromyzid leafminer damage in agricultural fields using wearable AR glasses and an AI model. This method can also be utilized to automatically diagnose pest and disease damage levels in other crops based on leaf images.
