MASK RECOGNITION MODEL TRAINING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2023/221608

A1

The present application provides a mask recognition model training method and apparatus, a device, and a storage medium. The method comprises: respectively cutting each picture in a first training set into a plurality of image blocks having the same size, and performing tag labeling on the image blocks to obtain a second training set; respectively cutting each picture in a third training set into a plurality of image blocks having the same size, and performing tag labeling on the image blocks to obtain a fourth training set; pre-training a first preset model by using the second training set to obtain a pre-trained model; and performing formal training by using the fourth training set and a second preset model to obtain a mask recognition model, wherein the first preset model and the second preset model can use a YOLOV4-tiny network model, the YOLOV4-tiny network model comprises a backbone network and a remaining part of networks, and parameters of the backbone network of the models in the pre-training and formal training are frozen. According to the method, an operation speed of the model and the accuracy of recognition of a small target at a relatively long distance are improved.
