Abstract[English]
A fit detection system for a respiratory protection device is presented. The system includes a camera that captures an image sequence of a user wearing the respiratory protection device. The system also includes a feature extractor that analyzes the image sequence and extracts features from the image sequence. The system also includes a fit score calculator that analyzes the extracted features and calculates a fit score indicative of how well the respiratory protection device fits the user. The system also includes a communication component that communicates the fit score.[French]
L'invention concerne un système de détection d'ajustement pour un dispositif de protection respiratoire. Le système comprend une caméra qui capture une séquence d'images d'un utilisateur portant le dispositif de protection respiratoire. Le système comprend également un extracteur de caractéristiques qui analyse la séquence d'images et extrait des caractéristiques de la séquence d'images. Le système comprend également un calculateur de score d'ajustement qui analyse les caractéristiques extraites et calcule un score d'ajustement indiquant l'efficacité avec laquelle le dispositif de protection respiratoire s'adapte à l'utilisateur. Le système comprend également un élément de communication qui communique le score d'ajustement.
