Human body physiological pressure evaluation method and device

Abstract

The invention discloses a human body physical stress evaluation method and device. A video signal of a human body finger end is acquired by a camera, and is decomposed into a graph sequence accordingto time; each graph in the graph sequence is subjected to pixel summing and averaging according to space to be converted into point data; the point data is synthesized into pulse wave signals according to time; the pulse wave signals are converted into an eigenvalue interval variable set; performing statistical variable calculation according to the eigenvalue interval variable set; Statistical variables are used to quantitative evaluation on human body physical stress is performed on the basis of statistical variables. The beneficial effect is that an external sensor does not need to be bought, and only a smartphone with a camera is needed to use in terms of hardware. The method is easy to implement, has good reproducibility, and can be used in many fields such as human body physical stress evaluation for a wide range of people, and treatment effect feedback.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for assessing human physiological pressure. Background technique [0002] Stress, also known as stress or tension, refers to the physiological changes and emotional fluctuations of people caused by changes in the external environment and internal state of the body. Chronic stress develops when you experience too much stress for too long. Numerous studies have shown that chronic stress can induce various diseases in the human body, such as chronic respiratory disease, heart disease, stroke, and even cancer. Therefore, measuring stress and reducing it in time is of great significance to maintaining health. [0003] Stress can be measured with the Stress index (SI). Traditional stress measurement methods mainly use stress test scales, such as the "psychological and physical tension and relaxation test table". Although the test scale is simple to use, each te...
