    摘要:

    针对葡萄园害虫识别过程中害虫种类繁多、形态属性复杂、实体间深层次关联关系差等因素导致的识别准确率不够高的问题,该研究提出一种基于属性特征知识图谱的细粒度葡萄害虫识别模型。该模型以视觉编码器作为提取图像高层表征的骨干网络,并结合知识图谱具有在描述害虫实体属性特征和害虫实体间关联方面的优势,将知识图谱所提供的细粒度属性特征和害虫实体关联特征信息用于葡萄园害虫分类研究。该方法在2个数据集上进行了测试:一是GP21数据集,该数据集由公开大规模害虫数据集IP102中21类葡萄园相关害虫类别图像构成;二是GP8数据集,该数据集包含从农业生产基地实地采集并手工标注的8种葡萄园害虫。试验结果表明,该文所提模型性能明显优于普遍通用预训练网络模型,分类准确率在GP21数据集和GP8数据集上分别达到了91.21%和95.03%,相比于仅使用视觉编码器分别增加1.64和1.17个百分点。这证明属性特征知识图谱的引入能够辅助视觉编码器捕获细粒度更高的葡萄园害虫特征信息,有效解决了葡萄园害虫识别中的精度不够高的问题。

    Abstract:

    Pest infestation is one of the main reasons for the decrease in crop yield and quality in vineyards. Deep learning can be expected to identify the pest species for scientific prevention and control strategies, in order to improve the production level of vineyards. In this study, an identification model was proposed, termed as ACKGViT (attribute characteristics knowledge graph enhanced vision transformer), for the fine-grained vineyard pest using constructed attribute characteristics knowledge graph (KG). Particularly, the KG was fully utilized to treat the variety, complex morphology, and low correlation of vineyard pests. A specific description was also given for the entity attribute characteristics and inter-entity association of pests. The improved approach was then applied in various agricultural settings. Pest recognition challenges were clarified across diverse domains. The inherent structure of KGs incorporated valuable contextual complements with the visual features extracted by the visual encoder. The graph convolutional network facilitated the efficient learning of pest attributes and relationships from the KG. This information was then seamlessly integrated into the classification. ViT (vision transformer) was used as the backbone network to extract the high-level representation of images. The fine-grained attribute was combined with the associated features provided by KG for pest identification in vineyards. The KG recognition model of vineyard pests was also trained and optimized using traditional features of images. Traditional image features (such as color, texture, and shape) were extracted using various techniques, including histogram-based methods, wavelet transform, and local binary patterns. The essential information was obtained about the pest species and their characteristics, enabling the KG to accurately capture the associations between different pests. Two datasets were evaluated: one was the GP21 dataset, which was composed of 21 vine-related pest categories from the IP102 public large-scale pest dataset, and another was the GP8 dataset, including eight vine-related pest categories that were collected from agricultural production sites and hand-labelled. The experimental results show that the performance of ACKGViT was significantly better than the general pre-training networks. The accuracies of GP21 and GP8 datasets reached 91.21% and 95.03% respectively, which increased by 1.64 and 1.17 percentage points, compared with the original ViT. The attribute characteristic KG was introduced to assist the ViT with more pest information on the vineyard. In conclusion, accurate and rapid pest identification was offered for the fine-grained vineyard pest recognition model with attribute feature KGs. The improved model can substantially contribute to the targeted and effective pest prevention and control strategies, and further improve the grape yield, quality, and overall productivity in vineyards. Future work can expand the KG into additional attributes and relationships. Other sources of information can also be introduced, such as temporal data or expert knowledge. Furthermore, the proposed approach can be extended into other agricultural domains, indicating the versatility of pest recognition under various settings. Additionally, better performance can be expected to achieve in the high efficiency of the graph convolutional network and the full integration of KG information during classification.
