Abstract
The present invention discloses a detection device for respiratory frequency detection. The detection device for the respiratory frequency detection comprises a first mark, a second mark, an image acquisition unit and a processing unit; a relative position between the first mark and the second mark changes periodically with breath of testers; the image acquisition unit acquires a video image of the position change of the first mark and the second mark when the testers breath; the processing unit separates the video image into video frames with a sequence of time order, specific video frames are selected, and positions of the first markers and the second markers in each of the selected video frames are identified; distances between the first marks and the second marks in each of the selected video frames are measured to form a time-distance curve graph; and counting of periods of the time-distance curve graph in specific time is conducted. The detection device is simple in application and relatively low in cost, and can conduct relatively accurate detection of respiratory frequency of the testers.
Description
[0001] This application is a divisional application for an invention patent with an application date of March 09, 2018, application number 201810194475.7, and the name "Respiratory Frequency Detection Method and Detection Device for Respiratory Frequency Detection". technical field [0002] The invention relates to the field of medical detection equipment, in particular to a detection device for respiratory frequency detection. Background technique [0003] Respiration is one of the important factors to measure the physiological health index of human body. The detection of respiratory frequency is of great significance to respiratory diseases such as cold, fever, cough, asthma, lung disease, heart disease, and sleep apnea syndrome. [0004] In the prior art, detection methods of respiratory frequency mainly include contact measurement method and non-contact measurement method. In the contact measurement method, the measurer needs to carry, bundle or paste the breathing sens...
