The special construction of human body skin and the optical phenomena having its initiation are by the theoretical foundation that skin image is processed, 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, is horny layer respectively, epidermal area, the skin corium containing tremulous pulse and venous capillary, and
Hypodermis layer containing fat.The optical phenomena producing between each layer of skin and incident illumination is not quite similar, different skin
Pigment in layer is also different to the absorption of light.The present embodiment major embodiment epidermal area and skin corium are special to the absorption of light and reflection
Property, this is also the main cause leading to energy of reflection light change.
Incident ray creates the optical phenomena of complexity with skin during contacting.Incident ray reaches the table of skin
During face, about 5% is directly mirrored, and remaining major part will enter the lower surface of skin.Incident illumination enter epidermal area it
Afterwards some by melanin absorption, a part is scattered, and the light of remainder enters following corium by penetrating epidermal area
Layer.And the presence due to hematochrome, skin corium equally exists the absorption to light and scattering phenomenon.It is a difference in that,
Light is by forward scattering mostly in epidermal area, thus comparatively fairly simple.And after entering into skin corium, light
Forward scattering and back scattering will be produced, the particularly scattering phenomenon after the upper strata of skin corium-mastoid process layer is more serious, makes
Obtain portion of incident light and return in the air.Lamina reticularises under skin corium, most of is forward scattering, and light will reach up to
Subcutaneous tissue is simultaneously reflected into and penetrates light and remove some outside surface and lower surface are reflected back in the air, remaining all
By the pigment absorption in skin.Although the kind of pigment containing in skin is varied, be present in epidermal area melanin and
The hematochrome of skin corium is the most obvious to the absorption of light, therefore, when in skin, melanin and other organizational structure are unchanged, blood
Pigment number directly affect the absorption of incident illumination, and finally change the energy of reflection light entering ccd.

In movement, deviation may be occurred on the acquisition of each image, then facial sensitizing range in previous frame be used as current
Facial sensitizing range in frame, makes Image Acquisition have certain seriality.Video pre-filtering module 68 is used for the face chosen
The frame of video of portion sensitizing range is measured, and when the frame number of metering reaches default frame number, described frame of video is sent to video
Processing and amplifying module;When the frame number not up to default frame number of metering, continue metering frame of video until reaching default frame number;So
Default frame number be that processor operational capability according to entrained by control device is determined.Operational capability then can be preset by force relatively
Many frame numbers, disposal ability is weak then to preset less frame number.Video amplifier processing module 69 is used for described video pre-filtering mould
The frame of video that block sends carries out video amplifier process, the frame of video after processing and amplifying is decomposed in rgb color space, shape
Become three width single channel image;Calculate the spatial averaging of pixel in the facial sensitizing range of triple channel image respectively, formed and correspond to
Three signal values of the RGB of each frame, between 0 ~ 255, three signal values of RGB of each frame form three to signal value scope
Individual original signal sequence, so that amplify from each frame heart rate signal;When the length of frame of video reaches specific length, this reality
Applying example and setting the time span of use is 30 seconds, and that is, the frame per second of the length of frame of video to be 30 seconds be multiplied by video, just enters to video segment
Row video amplifier is processed, and the video after amplification carries out the extraction of heart rate signal.Video frame number just updated once every 1 second, carried out
Video amplifier is processed that is to say, that the frame of video having 90% in the video of adjacent video amplifier twice process is identical next time.
By the rgb passage of each frame processing in rear video separately, and calculate the space of pixel in each passage face sensitizing range respectively
Meansigma methodss, thus obtain three values between 0 ~ 255.Area-of-interest corresponding to 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 limit here.
Normalization needs to also needing to carry out bandpass filtering treatment to the signal in window after completing, with eliminate low frequency breath signal and
The impact to heart rate detection result for the high-frequency noise.Heart rate signal denoising Processing module is used for original signal sequence is carried
Pass filter is processed, to adjust signal waveform and to eliminate effect of noise;Heart rate range in view of normal person is 45 ~ 240, therefore
Upper lower limiting frequency using band filter is respectively 0.75hz and 4hz.Heart rate value modular converter is used for elimination noise
It is a kind of highly effective algorithm of dft, referred to as fast fourier transform (fast that three signal sequences carry out fft conversion fft respectively
Fourier transform), calculate the corresponding power spectral density of three signal sequences, choose maximum work in g channel signal sequence
The corresponding frequency of rate is as the value of calculation of heart rate;Three signal sequences after bandpass filtering treatment carry out fast Fourier transform
To respectively obtain the power spectral density of three signal sequences.The pulse wave signal that g passage in video image comprises is stronger, therefore
The peak power choosing the signal sequence that pixel average is formed in g passage area-of-interest composes corresponding frequency as heart rate value.

The oxygen uptake of user of service of conversion is compared with default oxygen uptake, when the oxygen uptake of user of service takes the photograph oxygen less than default
During amount, alarm module sends alarm;
From data in table, when heart rate meansigma methodss are less than 92 beats/min, oxygen consumption of often fighting is 7.576 milliliters, heart rate
Oxygen consumption of often fighting during for 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
When, oxygen consumption of often fighting is 9.130 milliliters.Heart rate reaches oxygen consumption of often fighting when 175 beats/min and is 9.130 milliliters.Thus it is converted into
It can be deduced that required oxygen consumption when user works in cable tunnel.When the oxygen uptake of user of service is less than default taking the photograph
