Protective Mask Wearing Recognition Based on Improved VGG-16 Deep Learning Network
To efficiently identify whether polishing and welding operators are wearing protective masks,an improved deep learning model of VGG-16 network was proposed,and a deep feature extraction network based on VGG-16 was constructed to mine important information of images.To address the shortcomings of the VGG-16 network in capturing local image features and global structural information,a spatial position information perception mechanism based on coordi-nate attention was established to enhance the attention to image position and channel information.Finally,a classification network based on multiple fully connect-ed layers was established to output recognition re-sults.The experimental results showed that the recog-nition accuracy,precision,recall,and F1 score of this model for whether polishing and welding opera-tors wore protective masks reached 95.88%,96.48%,95.25%,and 95.86%,respectively,which had bet-ter performance than traditional manual inspection methods.
