The objective of the invention is to solve the problem that prior art exists, by the improvement to sample preparation methods in the prior art, the appliance computer image analysis technology is directly measured dermatoglyph and wrinkle.
Method of the present invention comprises the preparation of the multiple membrane sample of skin silica gel and the measurement of dermatoglyph and wrinkle, wherein: the preparation of the multiple membrane sample of (1) skin silica gel is followed successively by with ultra-fine silica gel and answers film at tested position, through solidifying the cross-section section of film of writing in reply after stable, arrange in order in the cross section of section, and it is to be measured to make multiple membrane sample; (2) appearance profile that is measured as the multiple membrane sample that will arrange in order with the cross section of dermatoglyph and wrinkle amplifies and videotapes and import computer, machine ias as calculated, measure the nearly skin of the multiple membrane sample of skin one by one and survey the height of rat, record the degree of depth of dermatoglyph and wrinkle.
Fig. 1 is the multiple film of the silica gel of place, canthus skin.
Fig. 2 is the cross-section section that the multiple film of Fig. 1 is arranged in order.
Fig. 3, Fig. 4, Fig. 5 are the multiple film measurement result curve maps of three Different Individual skins.
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Embodiment one: we selected human body the earliest and the tail of the eye place skin of the easiest generation wrinkle be tested position, the concrete operations step is: clean once with 70% alcoholic solution and physiological saline respectively at left or right tail of the eye place, after drying, with the canthus is sign, on the skin up and down in its outside, evenly smear the about 3 * 4cm of area with the ultra-fine silica gel that adds curing agent.After silica gel curing is stable, gently it is peeled off with tweezers, promptly obtain the multiple membrane sample of skin surface structure, (as shown in Figure 1), will answer film again is sign with the canthus, along the cross-section section of membrane sample of writing in reply of canthus horizontal line, every thick about 0.75mm (± 10 μ m), arrange according to the order of sequence in the cross section of section, (as shown in Figure 2), so far sample preparation finishes, and is to be measured.Known computer image analysis technique is used in the measurement of dermatoglyph and wrinkle, and all can be measured descriptive geometry CALCULATION OF PARAMETERS machine analytical system and can use.Above-mentioned multiple film section is arranged with the cross section order, and use microscope and video camera that its appearance profile is amplified the back and take in, and the input computer aided video system, measure the skin height of film rat again one by one, measurement category is 1.5 * 1.0cm.Because the multiple film of this skin silica gel is the negative of dermatoglyph and wrinkle, so multiple nearly skin side height of projection of the cross-section tangent plane of film of the skin that records, promptly represented the actual grade of dermatoglyph and wrinkle, all mensuration numerical value, the degree of depth according to dermatoglyph and wrinkle, machine classification or statistical disposition as calculated, the result is with all kinds of textures, the sum of wrinkle or account for the ratio value representation of total amount.
Embodiment two: with method of the present invention to the mensuration of the blue or green application on human skin texture of normal year and the preliminary observation of feature thereof
In order to determine the boundary of dermatoglyph and trickle wrinkle, we have investigated 37 ages between 18-23 year, the Healthy Youth men and women that place, canthus skin naked eyes are not seen wrinkle and do not had a dermatopathy use the method preparation multiple membrane sample identical with embodiment one through videotape and as calculated machine image analysis measurement result show what table one.
| Sex | Number | Mean age | The dermatoglyph degree of depth (um) | Average every example is measured frequency | ||
