Measuring method for physiological parameter

Abstract

The invention provides a measuring method for physiological parameters, and belongs to the technical field of physiological signals, and especially relates to a measuring method for physiological parameters. The invention provides a measuring method for physiological parameters, and the method is low in use cost and good in measuring effect. The method comprises the following steps: 1) a user finger covering a mobile phone camera, turning on a mobile phone flash lamp, and taking pictures by an image sensor in the mobile phone camera; 2) a mobile phone performing quantization determining on green ray value of RGB of all pixels in each frame of images, and calculating average gray value, to draw a green ray curve, calculating color variation of each frame, to form a pulse wave curve; performing median filtering on the pulse wave, and removing baseline drift; 3) inputting user body parameters; and finding a main wave crest, a dicrotic crest, the height of the main wave crest, the height of the dicrotic crest in the pulse wave which is processed by filtering, and calculating physiological parameters of a human body through the parameters.

Description

technical field [0001] The invention belongs to the technical field of physiological signal measurement, and in particular relates to a method for measuring physiological parameters. Background technique [0002] The traditional clinical method of measuring the pulse wave is to collect the pulse signal of the finger through an infrared finger clip. Although this method can obtain an ideal pulse wave signal, it needs medical equipment, which are expensive, troublesome to measure, and very inconvenient to measure at any time. [0003] With the rapid development of mobile technology, the camera pixels on mobile phones are getting higher and higher, and the speed of mobile phones is getting faster and faster. Some health measurement methods can also be found on the market, but these measurement methods generally only detect heart rate; There are some measurement methods that can measure other physiological parameters of the human body, but they need the help of other devices, a...

Although this method can obtain an ideal pulse wave signal, it needs medical equipment, which are expensive, troublesome to measure, and very inconvenient to measure at any time

[0003] With the rapid development of mobile technology, the camera pixels on mobile phones are getting higher and higher, and the speed of mobile phones is getting faster and faster. Some health measurement methods can also be found on the market, but these measurement methods generally only detect heart rate; There are some measurement methods that can measure other physiological parameters of the human body, but they need to use other devices, and then transmit them to the mobile phone through Bluetooth technology
