摘　　要：为了提高对管制物品的检测精度,本文提出一种结合RFB(receptive field block)网络结构和特征融合的目标检测算法。首先对采集的安检数据进行无效内容剔除、滤波;接着对安检数据进行人工标注和数据增强;然后在MobileNetV3-SSD算法的基础上,通过引入RFB网络改进其网络结构,以加强网络的特征提取能力,并利用特征融合的方法提高模型的小目标检测能力;最后,构建了一个安检数据集SCCI2020来验证算法的性能,该数据集包含91767张图片。实验结果表明,本算法在安检数据集SCCI2020上的检测精度为87.0%,比MobileNetV3-SSD算法的检测精度高2.7个百分点;在COCO2014和COCO2017通用数据集上的检测精度分别为21.9%和23%,相对于VGG16-SSD、MobileNetV3-SSD算法均有一定提升。In order to improve the detection accuracy of controlled items,a target detection algorithm that combines Receptive Field Block(RFB)network structure and feature fusion is proposed.First,the collected security inspection data are eliminated and filtered,then,the security inspection data are manually labeled and the data are enhanced.Based on the MobileNetV3-SSD algorithm,the RFB network is introduced to improve its network structure to strengthen the network’s feature extraction capabilities,and the feature fusion method is used to improve the model’s small target detection capability.Finally,a security inspection dataset SCCI2020 is constructed to verify the performance of the algorithm,where the dataset contains 91767 images.Experimental results show that the detection accuracy of this algorithm on the security inspection dataset SCCI2020 is 87.0%,which is 2.7 percentage point higher than the detection accuracy of the MobileNetV3-SSD algorithm.The detection accuracy on the COCO2014 general dataset and COCO2017 general dataset are 21.9%and 23%.Compared with VGG16-SSD and MobileNetV3-SSD algorithm,the detection accuracy is improved to a certain extent.
