Abstract

The invention discloses a mask recognition method and device based on an improved convolutional neural network, and is used for solving the problems that an existing convolutional neural network modelis relatively complex in parameter, too large in calculated amount, relatively low in recognition efficiency and poor in real-time performance. The method comprises the steps of acquiring a to-be-detected image; according to the improved MobileNet model, image features of the image to be detected are extracted based on channel convolution; and detecting and identifying the mask in the image to bedetected according to the CenterNet architecture and the image features. According to the method, the parameter quantity and calculation quantity of the model can be reduced, the size of the model isreduced, the calculation efficiency is improved, the detection instantaneity is improved and the time delay is reduced while the detection precision of the model is reserved as much as possible.

Description

technical field [0001] The present application relates to the technical field of object detection and recognition, in particular to a mask recognition method and device based on an improved convolutional neural network. Background technique [0002] Infectious disease is a disease that can be transmitted from person to person, and from person to animal through air, contact, and body fluids. During the epidemic of infectious diseases, the transmission of viruses can be blocked to a certain extent by wearing masks. Therefore, during the epidemic of infectious diseases, the public is usually required to wear masks and the wearing of masks is tested. [0003] At present, most neural network-based object detection and recognition methods usually mark the target on the image to be tested in the form of an axisymmetric frame, and the target detector exhaustively exhausts the potential target positions, and then conducts all potential target positions. Classification to get the co...
