It is understood that the relation of atmospheric pressure and suction gas oxygen dividing potential drop and blood oxygen saturation is with the change of height above sea level
Changing, the partial pressure of oxygen of ambient air declines, and atmospheric density diminishes, and the oxygenous quality of unit volume reduces the most accordingly, presses
Oxygen purity is 20.9%, temperature.DEG C calculate, if table air basic parameter is with shown in the change of height above sea level.Oxygen content hundred
Proportion by subtraction, with the atmospheric oxygen content of zero height above sea level as standard, increases with height above sea level, and it is to cause human body to lack that air oxygen content declines
The main cause of oxygen.
Atmospheric pressure reduces, and sucks gas decrease in oxygen partial pressure, and in lung, partial pressure of oxygen also decreases, and such hemoglobin is the most not
Can be by oxygen saturation, it may appear that supervenosity phenomenon.It is generally acknowledged (suitable 1500m height), people when air pressure is at 7.4x 104Pa
Knowing from experience and produce a series of physiological changies, but typically can adapt to, when air pressure is less than 5.3*104 Pa, human body adapts to arise that
Difficulty.In 8-8.5km eminence, the hemoglobin of only 50% is combined with oxygen, and in body, the deposit of oxygen is down to normal 45%, life
To be affected, therefore the general physiological limits that the atmospheric pressure value of 3.2* 104 Pa (being equivalent to 8.5km) is regarded as air pressure (highly).
The general symptom of anoxia is weak, dizziness, inappetence, pale complexion；Severe depletion of oxygen or acute anoxia then show
Give for dyspnea, skin purple, loss of consciousness, even go into a coma.Dissolve in the blood of 100 milliliters 37 DEG C, with physical state
Oxygen, every 0.003 milliliter of partial pressure of oxygen that can produce 0.133kPa.Normal person, at quiescent condition, breathes sea level air, with physics shape
About 0.3 milliliter of % of the oxygen that state is dissolved in arterial blood, arterial partial pressure of oxygen (Pa02) about 13.3kPa (100mmHg)；Venous oxygen
The normal about 5.32kPa (40mmHg) of dividing potential drop (Pv02).Owing to sucking partial pressure of oxygen and the change one of partial pressure of oxygen in blood of gas
Causing, i.e. suck gas oxygen dividing potential drop and increase, in blood, partial pressure of oxygen also increases, otherwise, all reduce.Therefore, the available gas oxygen that sucks divides
The change of pressure approximates and judges the change of partial pressure of oxygen in blood.
Suck gas oxygen dividing potential drop to be tried to achieve by the calculating about atmospheric pressure, it may be assumed that suck gas oxygen dividing potential drop=atmospheric pressure
Power * 20.9%.Suck gas oxygen dividing potential drop as shown in the table with the change of height above sea level.
Normal adults under rest state, about oxygen consumption 250mL per minute, i.e. oxygen demand every day about 360L, but internal storage
The oxygen deposited only about 1.5L, even if storage oxygen is all utilized the most enough tissues and consumes 4-5min.Therefore, it is necessary to constantly from outward
Boundary's oxygen intake, could maintain normal activities.If the supply of oxygen is not enough or owing to the metabolic process of internal oxygen hinders
Hindering, it is impossible to obtain enough oxygen or normally utilize oxygen, so that producing a series of changes of body, even threat to life, this just claims
For " anoxia ".

The special construction of human body skin and the theoretical foundation having its optical phenomena caused to be by skin image process, human body skin
Skin is a translucent body containing multiple structure, and different research worker has different views to the concrete layering of skin.Will
Skin regards semi-transparent configuration body as it is shown on figure 3, be horny layer respectively, epidermal area, true containing tremulous pulse and venous capillary
Cortex, and the hypodermis layer containing fat.The optical phenomena produced between each layer and the incident illumination of skin is not quite similar,
Pigment in different skin layer is the most different to the absorption of light.The present embodiment major embodiment epidermal area and skin corium to the absorption of light and
Reflection characteristic, this is also the main cause causing energy of reflection light to change.
Incident ray is creating the optical phenomena of complexity as shown in Figure 4 during contact skin.Incident ray arrives
When reaching the surface of skin, about 5% is directly mirrored, and remaining major part will enter the lower surface of skin.Incident illumination is entering
After entering epidermal area, some is scattered by melanin absorption, a part, and the light of remainder will penetrate epidermal area and enter
Following skin corium.And due to the existence of hematochrome, skin corium equally exists the absorption to light and scattering phenomenon.No
It is that light is by forward scattering mostly at epidermal area with part, thus the most fairly simple.And enter into skin corium
Afterwards, light general generation forward scattering and back scattering, the particularly scattering phenomenon after the upper strata of skin corium-mastoid process layer are relatively
For seriously so that portion of incident light returns in air.Lamina reticularis under skin corium, major part is forward scattering, light
To reach up to subcutaneous tissue being reflected into penetrate light remove some outside surface and lower surface are reflected back air,
Remaining all by the pigment absorption in skin.Although the kind of pigment contained in skin is varied, but is present in epidermal area
Melanin and the hematochrome of skin corium the most obvious, therefore, when melanin and other knot of tissue in skin to the absorption of light
When structure is unchanged, hematochrome number directly affect the absorption of incident illumination, and finally change the energy of reflection light entering CCD.
Facial zone arranges module for arranging face sensitizing range；Face sensitizing range includes the eyes of people, face, nose
Son and face, when people's nictation or open one's mouth to be will to cause the change of pixel in area-of-interest.Pixel in concrete face sensitizing range
Change be the change that blood causes the colour of skin when flowing through face blood capillary, i.e. the pixel change of human face region in video.
As Fig. 5, Fig. 6 show that face sensitizing range, face sensitizing range set distance between eyes as 4d, choose long with
The wide rectangle being respectively 8d and 10d, is shown in black dotted lines region, here it is the facial sensitizing range obtained；Then double
Eye distance from point midway above d distance choose one long and wide be respectively 3d and 3d/2 rectangle, attach most importance to analyze
Face sensitizing range；Long and the wide rectangle being respectively 8d and 3d, analysis of attaching most importance to is chosen at the 0.5d of the lower section at eyes midpoint
Facial sensitizing range.When detection obtains face sensitizing range, each frame video image is all with the lane place of this three part
Territory analyzes as face sensitizing range and conversion obtains heart rate.
Light source transceiver is used for obtaining face video image；Light source transceiver can use photographic head, obtains and examines for heart rate
The facial video image surveyed, can use high-resolution photographic head here, to improve the definition obtaining video image, it is ensured that
The accuracy of heart rate conversion.
Facial recognition modules chooses face sensitizing range conduct in each frame from the facial video image obtained
The extraction region of follow-up heart rate signal；When obtain video in, in a certain frame choose face sensitizing range failure time, make
With the facial sensitizing range in previous frame as the facial sensitizing range in present frame；The facial zone identification of facial recognition modules
The function being had by photographic head or video camera, for conventional means.Here facial recognition modules is from the facial video figure obtained
Each frame in Xiang is chosen the extraction region as follow-up heart rate signal, the face sensitizing range；Due to user at the volley,
In the acquisition of each image, deviation may occur, then use the facial sensitizing range in previous frame as the face in present frame
Sensitizing range, makes Image Acquisition have certain seriality.
Video pre-filtering module is for measuring the frame of video of the facial sensitizing range chosen, when the frame number of metering reaches
To when presetting frame number, frame of video is sent to video amplifier processing module；When the frame number of metering not up to presets frame number, continue
Metering frame of video is until reaching to preset frame number；Such default frame number is according to the processor operational capability institute entrained by treadmill
Determine.Operational capability the most then can preset more frame number, and disposal ability is weak, presets less frame number.
Video amplifier processing module carries out video amplifier process for the frame of video sending video pre-filtering module, will put
Frame of video after big process is decomposed in RGB color, forms three width single channel image；Calculate triple channel image respectively
Facial sensitizing range in the spatial averaging of pixel, form three signal values of RGB of corresponding each frame, signal value scope
Between 0 ~ 255, three signal values of the RGB of each frame form three original signal sequence, so that amplifying from each frame
Heart rate signal；
When the length of frame of video reaches specific length, it is 30 seconds that the present embodiment sets the time span of use, i.e. the length of frame of video
Degree is 30 seconds is multiplied by the frame per second of video, just video segment is carried out video amplifier process, and the video after amplification carries out heart rate signal
Extraction.Video frame number just updated once every 1 second, carries out video amplifier next time and processes, say, that adjacent twice video
The frame of video having 90% in the video of processing and amplifying is identical.The RGB channel of each frame processed in rear video is separated, and
Calculate the spatial averaging of pixel in each passage face sensitizing range respectively, thus obtain three values between 0 ~ 255.Corresponding
The area-of-interest of each frame in video is the formation of three sections of original signals of red, green, blue.
For the characteristic of observation signal, need signal is normalized.Concrete normalized mode is existing
Technology, is before treatment, has program staff according to practical situation, writes corresponding normalization formula and realizes, does not limits.
Normalization completes to need also needing to the signal in window is carried out bandpass filtering treatment afterwards, exhales eliminating low frequency
Inhale signal and the high-frequency noise impact on heart rate detection result.Heart rate signal denoising Processing module is for original signal sequence
Row carry out bandpass filtering treatment, to adjust signal waveform and to eliminate effect of noise；In view of the heart rate range of normal person be 45 ~
240, therefore use the upper lower limiting frequency of band filter to be respectively 0.75Hz and 4Hz.
Rate calculation module is a kind of DFT for three signal sequences eliminating noise are carried out FFT FFT respectively
Highly effective algorithm, referred to as fast fourier transform (fast Fourier transform), calculate the corresponding merit of three signal sequences
Rate spectrum density, chooses frequency that in G channel signal sequence, peak power the is corresponding value of calculation as heart rate；
Three signal sequences after bandpass filtering treatment carry out fast Fourier transform and respectively obtain three signal sequences
Power spectral density.The pulse wave signal that G passage in video image comprises is relatively strong, therefore chooses picture in G passage area-of-interest
The frequency of the peak power spectrum correspondence of the signal sequence that element average is formed is as heart rate value.
Heart rate is used for describing the technical term of cardiac cycle, refers to the heart number of times beated per minute, with the first sound is
Accurate.Heart rate during normal adult peace and quiet has significant individual variation, averagely at 75 times/about min.
Heart rate raises with height above sea level and increases.Height above sea level 2260m increases by 11.3% compared with the oxygen content of zero Altitude Regions, and 3000m increases
Adding 21.1%, 3450m increases by 25.0%, and 4100m increases by 33.8%.In the case of load exercise, same load raises the heart with height above sea level
Rate absolute value increases, and the oxygen content of each height above sea level load and zero Altitude Regions increases percentage ratio with heart rate during load and also increases, and 8 is public
In/oxygen content running heart rate hour in zero Altitude Regions is 95.1 times/min, 2260m is 105.1 times/min, and 3000m is
113.0 times/min, 3450m is 116.6 times/min, and 4100m is 121.7 times/min；When running on plateau, changes in heart rate another
One feature is that the oxygen content that the same height above sea level in plateau increases relatively zero Altitude Regions with load increases percentage ratio minimizing with heart rate during load.
May under anoxic conditions, parasympathetic activity strengthens, the partly cause that during running, heart rate reduces.The present embodiment with 8 kilometers/
Hour and 10 kilometers/hour run time changes in heart rate as a example by.
In order to make exercise heart rate and oxygen consumption have relation, it is simple to draw user's oxygen consumption when using treadmill,
Height above sea level arranges module for arranging the height above sea level of treadmill local environment；Height above sea level is used for oxygen content conversion module
Height above sea level according to treadmill local environment is converted to the oxygen content of height above sea level；
Concrete,
From data in table, when heart rate meansigma methods is below 92 beats/min, oxygen consumption of often fighting is 7.576 milliliters, heart rate
Oxygen consumption of often fighting when being less than 110 beats/min is 8.691 milliliters, and when heart rate reaches less than 130 beats/min, oxygen consumption of often fighting is
9.130 milliliters, when heart rate is increased to 150 beats/min, oxygen consumption of often fighting is 9.067 milliliters.Heart rate is increased to 165 beats/min
Time, oxygen consumption of often fighting is 9.130 milliliters.Oxygen consumption of often fighting when heart rate reaches 175 beats/min is 9.130 milliliters.Thus it is converted into
User when using treadmill, oxygen consumption required under the speed that difference is run.
In order to the conversion making heart rate further is the most accurate, treadmill operating rate conversion heart rate module is for according to running
The height above sea level of machine local environment and treadmill operating rate, be converted to the heart of active user in real time by treadmill operating rate
Rate；It is the height above sea level that can preset according to treadmill local environment and treadmill operating rate, will run in real time
Machine operating rate is converted to the heart rate of active user；So according to normal calculation, it can be deduced that heart rate value.
Heart rate correcting module is converted with treadmill operating rate for the heart rate calculated in real time according to rate calculation module
Treadmill operating rate is converted to the heart rate of active user and is weighted averagely obtaining the real-time correction heart by heart rate module in real time
Rate；Heart rate and oxygen consumption conversion module for being converted to the oxygen consumption of user by correction heart rate；
So two heart rate values are done weighted average and has obtained real-time correction heart rate, improved the accuracy obtaining heart rate value.
