Embodiment 1

[0055] In this embodiment, the intelligent video vital signs monitoring method combines figure 1 ,Proceed as follows:

[0056] The first step: the heart rate analysis and extraction module, use the camera to capture the face video image for heart rate detection, use the face detection algorithm to extract the region of interest, calculate the gray value of the three RGB channels, use independent component analysis and Blind source separation technology, the heart rate is obtained by the heartbeat interval mean method, and the processing steps are as follows:

[0057] Step 11, in the case of ordinary sunlight or fluorescent lamps as the light source, use the high-definition camera installed in the fitness club to shoot people who are doing fitness exercises such as running, and obtain face video images for heart rate detection.

[0058] Step 12, select a region of interest (ROI) from each frame in the acquired face video image as the extraction region of the subsequent heart r...

Abstract

The invention discloses a system and method for intelligent video monitoring of vital signs. The system comprises a heart rate analysis and extraction module, a cloud side database and an intelligent application module, wherein the heart rate analysis and extraction module and the intelligent application module are equipped with wireless communication modules respectively. The heart rate analysis and extraction module is used to shoot a human face video image, conduct human face detection, determine a human face area, process the human face area, determine a skin area, extract an interested area, compute gray averages of three RGB channels, apply independent component analysis to conduct blind source separation of signals and obtain a heart rate by a heart beat interval mean value method; the wireless communication modules upload the real-time heart rate obtained by the heart rate analysis and extraction module to the cloud side database and are connected to wireless intelligent communication equipment in the intelligent application module; and the intelligent application module is used to conduct the real-time monitoring and store heart rate information, and is also used to conduct early warning for physical health conditions. The system and the method disclosed by the invention are effective and reliable and have the advantages that vital sign signals can be monitored in real time; monitoring accuracy is high; timeliness is high; and applications are wide.

Description

technical field [0001] The invention belongs to the technical field of video medical treatment, in particular to an intelligent video vital sign monitoring system and method. Background technique [0002] At present, the heart rate detection method based on face video images generally uses the principle of photoplethysmography, adopts face detection technology, uses independent component analysis and power spectrum analysis methods, and can quickly complete non-contact heart rate detection for people in fitness. However, at present, this method has been perfected into an intelligent video vital sign monitoring system to achieve real-time monitoring of the user's health status, including storing user health data through the cloud database, and installing APP applications on wireless smart communication devices. Not reported. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent video vital sign monitoring system and method wit...
