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.

Facial zone setup module is used for arranging facial sensitizing range；Facial sensitizing range includes the eyes of people, face, nose Son and face, when people blinks or opens one's mouth to be will to cause the change of pixel in area-of-interest.The specifically pixel in facial sensitizing range Change be the change causing the colour of skin when blood flows through face blood capillary, that is, in video human face region pixel change.

Facial sensitizing range sets distance between eyes as 4d, chooses the long and wide rectangle being respectively 8d and 10d, as black Shown in color dashed region, here it is the facial sensitizing range obtaining；Then at the d distance above the point midway of eyes distance Choose a long and wide rectangle being respectively 3d and 3d/2, the facial sensitizing range of point analysiss of attaching most importance to；Lower section at eyes midpoint 0.5d at choose the long and wide rectangle being respectively 8d and 3d, the facial sensitizing range of point analysiss of attaching most importance to.Obtain face in detection During sensitizing range, each frame video image is all to analyze using the band of position of this three part as facial sensitizing range and to convert Obtain heart rate.Facial zone setup module 66 is used for arranging facial sensitizing range；Facial recognition photographic head is used for obtaining face and regards Frequency image；Facial recognition photographic head adopts high-resolution photographic head, to improve the definition obtaining video image it is ensured that heart rate The accuracy of conversion.It is quick that described facial recognition modules 67 are used for selection face in each frame from the facial video image obtaining Sensillary area domain is as the extraction region of follow-up heart rate signal；When the selection face sensitizing range in the video obtaining, in a certain frame During the failure of domain, facial sensitizing range in previous frame is used as the facial sensitizing range in present frame；Facial recognition modules Facial zone is identified as the function that photographic head or video camera have, for conventional means.Here facial recognition modules are from acquisition Facial video image in each frame in choose facial sensitizing range as the extraction region of follow-up heart rate signal；Due to people 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.
