| 摘要: | 隨著人工智慧技術的發展，植物病害的自動化識別已成為提升農業生產效率的關鍵。儘管深度學習模型在病害診斷中表現出色，但在複雜田間環境下，圖像若包含非葉片背景或多片葉子，現有方法難以精準判別葉片，亦無法對個別葉面的病癥進行細部分析。為克服此挑戰，本研究旨在開發一套更具穩健性與多功能性的智慧農業服務系統。
本文提出一種創新的雙階段深度學習識別策略：首先，利用 MobileNetV3 模型對輸入圖像進行葉片存在性預判；隨後，再結合 YOLOv11 模型對圖像中經確認的個別葉片進行精準的疾病檢測。此策略有效解決了複雜田間背景下病害識別的挑戰，能精確識別健康、赤星病 (Rust)、黑星病 (Scab) 及黑斑病 (Black rot) 等多種病癥。
本研究的學術貢獻在於首次整合葉片預判與病害物件偵測的雙階段深度學習模型（MobileNetV3 + YOLOv11），顯著提升了模型在非標準化輸入圖像下的病害識別穩健性與精準度。實務上，本研究開發的系統透過整合至 LINE Bot 平台，為農民提供了一站式的智慧農業解決方案。這不僅包含即時的病害診斷與地理位置結合的病害數據可視化，能有效呈現病害分佈趨勢，更拓展至提供即時天氣查詢、農產品價格查詢、雷達回波圖、系統使用說明等多樣化資訊服務。實驗結果表明，本系統能顯著提升現實農業場景中病害偵測的準確性、應用廣度與整體農業管理效率，為智慧農業的推動奠定堅實的技術基礎。;With the advancement of artificial intelligence technology, automated identification of plant diseases has become crucial for enhancing agricultural production efficiency. While deep learning models, such as convolutional neural networks and their variants, excel in disease diagnosis, existing methods struggle to accurately distinguish leaves from complex field backgrounds or when images contain multiple leaves, making detailed analysis of individual leaf symptoms challenging. To overcome these limitations, this study aims to develop a more robust and versatile smart agricultural service system.
This paper proposes an innovative two-stage deep learning identification strategy: first, a MobileNetV3 model performs preliminary leaf presence detection on input images to filter out irrelevant backgrounds; subsequently, a YOLOv11 model conducts precise disease detection on the confirmed individual leaves. This strategy effectively addresses the challenge of disease identification in complex field environments, accurately identifying various symptoms such as healthy, Rust, Scab, and Black rot.
The academic contribution of this research lies in its first-time integration of a two-stage deep learning model (MobileNetV3 for leaf pre-judgment and YOLOv11 for disease object detection). This significantly enhances the robustness and accuracy of disease identification for non-standardized input images. Practically, the system developed in this study, integrated into the LINE Bot platform, offers farmers a one-stop smart agricultural solution. This solution not only provides real-time disease diagnosis combined with geospatial visualization of disease data, effectively showcasing disease distribution trends, but also expands to include diverse information services such as real-time weather queries, agricultural product price inquiries, radar echo maps, and system usage instructions. Experimental results demonstrate that this system significantly improves the accuracy, application breadth, and overall agricultural management efficiency of disease detection in real-world agricultural scenarios, laying a solid technical foundation for advancing smart agriculture. |
