Abstract

The invention discloses a vision technology-based respiration monitoring device which can monitor the fluctuating change of the chest when a patient breathes without contact so as to monitor the vital sign of the patient. The vision technology-based respiration monitoring device comprises a camera, a processor, an image acquiring unit, an image preprocessing module, a contour characteristic extracting module and a respiration analyzing module, wherein the camera is used for obtaining a sequence image frame of the patient; the processor is used for carrying out analysis processing and input and output signal control on the sequence image frame and displaying a monitoring parameter on a connected display screen; the image acquiring unit is used for transmitting the sequence image frame of the camera to the processor for processing after acquiring the sequence image frame; the image preprocessing module is used for carrying out the processing of denoising, strengthening, and the like on the sequence image frame; the contour characteristic extracting module is used for extracting the contour characteristic when the patient breathes from the sequence image frame; and the respiration analyzing module is used for calculating respiration frequency according to the change rule of the contour characteristic along with time and carrying out skin color monitoring, and the like.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a breathing monitoring device based on vision technology. Background technique [0002] Life monitoring generally monitors the beating of the heart, or monitors breathing conditions. The monitoring method is to use a contact sensor for detection, which requires installation and connection of the sensor, which is inconvenient to use. For example, a patent document with a publication date of June 22, 2011 and a publication number of CN 102100558A discloses a technical solution: a wireless respiratory monitoring device, including a control circuit, a piezoelectric film sensor and an antenna. The piezoelectric film sensor is electrically connected to the antenna, and the piezoelectric film sensor is used to sense the respiratory movement and convert it into a corresponding charge signal, which is processed by the control circuit to obtain a corresponding monitoring result, and then ...
