摘要
害虫是影响油茶(Camellia spp.)产量的主要因素之一,对其进行准确识别有助于及时防控,减少损失。目前,油茶害虫识别研究缺少相关的数据集,限制了深度学习技术在油茶害虫识别中的应用。为给在生态环境下准确识别油茶害虫提供1种新范式,构建包含1116张7类害虫的油茶害虫识别图像数据集,采用4种目标检测算法(SSD、YOLOv3、YOLOX和RetinaNet)在该数据集上进行试验。结果表明,IOU阈值为0.5时,SSD的平均精度为93.50%,YOLOX为93.50%,RetinaNet为86.80%,YOLOv3为96.60%;SSD的平均召回率为73.20%,YOLOX为75.10%,RetinaNet为78.00%,YOLOv3为76.80%。综合分析,YOLOv3的检测和分类能力最优。
Pests are one of the most significant factors affecting yields of Camellia spp.,and accurate identifica⁃tion of pests is helpful to control timely and reduce losses.However,relevant datasets were lacked in identifica⁃tion researches of Camellia spp.pests,which limited application of deep learning technology.To provide a new model for accurate identification of Camellia spp.pests in ecological environment,a Camellia spp.pests recog⁃nition dataset was constructed,which contained 1116 images of 7 classes of pests.Object detection algorithms SSD,YOLOv3,YOLOX and RetinaNet were experimented based on the dataset.Results showed that when IOU threshold was 0.5,average accuracy of SSD was 93.50%,YOLOX was 93.50%,RetinaNet was 86.80%,and YO⁃LOv3 was 96.60%;average recall of SSD was 73.20%,YOLOX was 75.10%,RetinaNet was 78.00%,and YO⁃LOv3 was 76.80%.YOLOv3 had the best abilities of detection and classification by comprehensive analysis.
