    摘要:

    為實現(xiàn)枇杷采后快速、準確篩選,,本文以MobileViT為主干特征提取網(wǎng)絡,,通過分別在Layer1和Layer2層之后嵌入注意力模塊CBAM(Convolutional block attention module),,強化網(wǎng)絡在通道和空間上對細節(jié)特征的提取能力,構建了一種輕量化網(wǎng)絡模型MobileViT-CBAM,。相較于MobileViT,,在驗證集和測試集上本文方法對疤痕、機械傷,、腐爛等缺陷果的識別準確率分別提高1.17,、1.23個百分點。試驗結果表明,,MobileViT-CBAM模型與VGG16,、ResNet34、MobileNetV2相比較,,準確率最高(97.86%),,同時兼具內(nèi)存占用量小(3.768 MB),、推理時間短(每幅圖像需42 ms)的優(yōu)勢,。該輕量化網(wǎng)絡模型可部署于嵌入式系統(tǒng)。本研究為構建枇杷在線檢測系統(tǒng)提供了缺陷識別理論基礎,,為枇杷等農(nóng)產(chǎn)品外部品質(zhì)檢測提供了一個高效,、準確的方法。

    Abstract:

    The MobileViT as the main feature extraction network was employed in order to accomplish quick and precise post-harvest screening of loquats in the paper. A lightweight network model called MobileViT-CBAM was developed as a result of strengthening the network’s capacity to extract detailed features in both channel and spatial dimensions by inserting convolutional block attention module (CBAM) after Layer1 and Layer2. The method outperformed MobileViT in terms of defect recognition accuracy, showing gains of 1.17 percentage points on the validation set and 1.23 percentage points on the test set for things like scars, mechanical damage, and decaying fruits. According to experimental results, the MobileViT-CBAM model performed better in terms of accuracy (97.86%) than VGG16, ResNet34, and MobileNetV2. It also had the advantage of having a small memory footprint (3.768 MB) and a rapid inference time (42 ms per image). It was possible to use this lightweight network model on embedded systems. The research offered an effective and precise technique for external quality inspection of loquats and other agricultural products by providing a theoretical framework for fault recognition in the construction of an online detection system for loquats.
