Seven-step hand washing method operation standardization automatic detection method

Abstract

A seven-step hand washing method operation standardization automatic detection method comprises the following steps of S1, using a camera arranged above a wash basin for collecting a hand washing video; S2, performing screenshot on the hand-washing video and preprocessing the hand-washing video according to the actual condition of hardware and the requirement of the detection frame rate; S3, inputting each frame of preprocessed image into a clipped YOLOv3 gesture type detection network trained by adopting an adaptive learning rate algorithm to obtain a gesture type of each frame and a confidence coefficient thereof; S4, calculating the arrangement sequence, the effective time and the corrected average confidence coefficient of each gesture type based on all detected gesture information; and S5, based on the obtained characteristic value of each gesture type, scoring according to a normativity evaluation rule, and carrying out normativity evaluation on the hand washing operation according to the normativity evaluation rule. The objectivity of evaluation is improved, and implementation of effective supervision is facilitated; the gesture type detection speed and accuracy are improved; and evaluation rationality is improved.

Description

technical field [0001] The present invention relates to the field of deep learning and gesture recognition, in particular to a YOLOv3-based seven-step hand washing method operation normative automatic detection method, and in particular to an automatic gesture recognition method based on the third generation You Only Look Once (YOLOv3 for short). Background technique [0002] Hand hygiene is an important means of preventing hospital disease transmission and cross-infection. It usually refers to various methods of removing pathogenic organisms on the skin surface of hands, mainly referring to hand washing, surgical hand disinfection and hygienic hand disinfection. It is the most convenient and effective way to prevent and control nosocomial infection. method. As a representative of the standard hand washing method, the seven-step hand washing method can not only remove surface stains and debris, but also eliminate pathogenic bacteria. Therefore, this method plays an important...
