Problems solved by technology

Although this method can realize non-invasive and continuous measurement, the processing method is too simple and the accuracy is low by using ordinary linear dimension reduction, and it can only provide human heart rate information, which cannot meet the increasing various measurement needs of modern society.

Embodiment

[0046] In this embodiment, a computer (Dell Optiplex790) connected to an external camera (Logitech C170) is used to record video for analysis. Video data is collected in color (24-bit RGB, 3-channel 8-bit / channel), 30 frames per second (fps), resolution format, and saved in AVI format with MEPG compression. attached figure 1 It is a flowchart of the method of the present invention. attached figure 2 It is the system architecture diagram of this example. The specific content of the method in this example is as follows:

[0047] In the video collected by the camera, the "Haar-like face detector" constructed by Adaboost is used to detect the face area in each frame. In the following reference, Proceedings of the IEEE Conference on Image Processing, pp. 900-903, "An Extended Set of Haar-like Features for Rapid Object Detection" by R. Lienhart and J. Maydt. 2002, provides Detailed information about the Haar-like face detector; the collection of visual information is to detect...

Abstract

The invention relates to a method and a system for monitoring human physiological indexes by using visual information. The method includes the following steps: collecting the visual information of a to-be-monitored object through a collection device and saving datum; processing the selected visual information; analyzing processed results to extract the human physiological indexes; and returning the extracted human physiological indexes for display. The system comprises a module used for collecting the visual information, a module used for processing the collected visual information and a module used for analyzing processed signals to extract the human physiological indexes. According to the method and the system for monitoring the human physiological indexes by using the visual information, noninvasive and continuous monitoring of human physiological status and synchronous detection and collaborative analysis of the multiple physiological indexes are achieved, monitoring accuracy is high, wire layout is simple, and the method and the system for monitoring the human physiological indexes by using the visual information can be easily popularized as household medical care contents.

Description

technical field [0001] The invention relates to a method and system for monitoring human physiological indicators by using visual information, belonging to the technical field of detection. Background technique [0002] Non-invasive and continuous monitoring of physiological indicators such as human heart rate and respiration rate is of great significance in home medical care and monitoring of human physiological conditions. With the improvement of domestic living standards, great changes have taken place in people's dietary structure and living habits: the content of dietary fat and cholesterol has increased significantly, and high-fiber components such as vegetables have decreased; daily activities have decreased, irregular work and rest, and life Faster pace, increased stress, etc., have become hotbeds for cardiovascular disease, which has become an important cause of death in developing countries. However, the usual medical testing requires the support of fixed precisio...
