Mask wearing identification method

Abstract

The invention discloses a mask wearing recognition method, which includes: training a face detection model and training a mask wearing recognition model. The face detection model training process includes: building a face detection network based on MTCNN, and training to obtain a robust A face detection model with high reliability, realizes the prediction of the face area and facial key point position in the spectral image, and narrows the detection range of the mask wearing model. The mask recognition model training process includes: marking the sample ROI on the face spectrum image, obtaining the sample coordinate information and category information through the sample ROI file, and constructing a data set; by training the SVM classifier, the model parameters are obtained, which are used in the face image. recognition. This method can realize automatic non-contact mask wearing detection, fast positioning and detection speed of the face, and can accurately distinguish between using clothing to cover the mouth and nose and wearing a mask correctly, greatly reducing false detections caused by clothing covering, and accurate The rate is high.

Description

technical field [0001] The invention relates to a mask wearing recognition method, which belongs to the field of target detection. Background technique [0002] In crowded places such as hospitals and public transportation, staff need to check whether pedestrians wear masks one by one, and the workload is quite heavy. Existing mask detection methods generally cannot distinguish whether the mask is worn correctly or is covered by hands or clothing. Therefore, a new method is needed to accurately distinguish between wearing a mask correctly and being blocked. Contents of the invention [0003] The purpose of the present invention is to provide a mask wearing identification method, improve the sorting speed and sorting accuracy of various and irregular complex parts on the production line, improve the sorting efficiency, and thereby increase productivity. [0004] A mask wearing identification method, the method comprises the following steps: [0005] S1. Carry out face det...
