Abstract

The invention belongs to the field of machine vision and data recognition, particularly relates to a transfomer-based non-contact respiratory rate measurement method, system and device, and aims to solve the problem that the measured respiratory rate is poor in precision due to the fact that a model obtained by an existing respiratory rate measurement method is poor in generalization ability. The method comprises the following steps: acquiring a to-be-detected video frame sequence containing face information in a set time period; obtaining a face region-of-interest image sequence through a face detection model and a face key point model based on the to-be-detected video frame sequence; and on the basis of the face region-of-interest image sequence, acquiring a respiration rate sequence in a set time period through a trained end-to-end Transform model. The measurement precision of the respiratory rate is improved.

Description

technical field [0001] The invention relates to the fields of machine vision and data recognition, in particular to a transfomer-based non-contact respiration rate measurement method, system and equipment. Background technique [0002] Respiratory rate is defined as the number of breaths a person takes in one minute during rest. The number of breaths we take per minute indicates how often our brain is telling the body to breathe. Also: "normal" breathing rates may vary with age. Normal ranges for respiration rates in children of different ages include: Newborns: 30-60 breaths per minute; Infants (1 to 12 months): 30-60 breaths per minute; Toddlers (1-2 years): 24- 40 breaths; preschoolers (3-5 years): 22-34 breaths per minute; school-age children (6-12 years): 18-30 breaths per minute; adolescents (13-17 years): 12 breaths per minute -16 breaths. In general: Respiration rate measurements are taken while a person is at rest. [0003] In the early research on respiration ...
