specific Embodiment approach

[0064] A specific embodiment of a training improvement Slim-YOLOV3 model, including:

[0065] S1: Get the original data set, and classify the original data set, the results of the classification include: specification wearing hood map, not standardizing wearing mask, not wearing mask Figure three class;

[0066] S2: Divide the classified data set to obtain the training sample set and test sample set; data enhancement processing is performed on the training sample.

[0067] S3: Enter the image of the enhanced training sample into the YOLOV3 network model of the backbone network DarkNet-53, extracts multi-scale classification features and positioning features;

[0068] S4: Two feature layers need to be output, and the two feature layers are located at different locations of the trunk portion Darknet 53, located in the middle lower layer, the underlayer, and the two feature layers are (26, 26, 512) and (13, 13, 1024), respectively. Then, two feature layers are subjected to 5 convolut...

Abstract

The invention belongs to the technical field of deep learning target detection and computer vision, and particularly relates to a Slim-YOLOv3-based mask wearing condition detection method, which comprises the following steps: acquiring face video data in real time, and preprocessing the face video data; and inputting the preprocessed face image into the trained Slim-YOLOv3 model, and judging whether the user correctly wears the mask or not. According to the invention, through adoption of the Slim-YOLOv3-based mask wearing condition video detection method and an improved unsupervised self-classification method, sub-class division is carried out on data of non-standard mask wearing, so that a mask wearing video detection task can be realized more accurately and rapidly. The proposed network is more concise, so that the application cost is further reduced.

Description

Technical field [0001] The present invention belongs to depth learning objective detection and computer visual technology, and in particular, the present invention relates to the detection method of mask wearing sites based on Slim-Yolov3. Background technique [0002] Due to harmful gases, odors, foams, viruses, all virus, through air, to effectively prevent the material invading the human body by standardizing the wearing mask. The role of the standard wearing mask is not only to prevent viruses from spreading from the invisible person to others, reducing the probability of secondary communication to protect others, but also protect the wearer, reduce the amount of virus in contact with the wearer, make the virus The risk of infection is lower. [0003] In recent years, deep learning has made great progress in the fields of target testing, image classification, semantic segmentation. Combined with various algorithms of convolutional neural networks, both precision or computatio...
