The object of the invention provides a kind of apparatus and method for measuring the hair gloss degree, can estimate objectively the glossiness of hair.The present invention is directed to the problem of above-mentioned present existence, can not accurately pass judgment on different hair care products to the impact of hair gloss degree in order to overcome existing glossiness appraisal procedure, so that the low deficiency of measurement result and the results of sensory evaluation goodness of fit.
The technical solution adopted in the present invention: a kind of device of measuring the hair gloss degree that exsomatizes comprises digital camera 1, lucifuge black box 2, light-source system 3, hair stationary cylinder 4.Lucifuge black box 2 is light tight casing, long 60-80cm, wide 30-50cm, high 40-60cm; End at lucifuge black box 2 is installed digital camera 1, and digital camera 1 is 1,800 ten thousand pixels or more high-resolution digital camera; Light-source system 3 is installed at lucifuge black box 2 middle parts, light-source system 3 comprises that the 220v alternating current transfers the circuit conversion device of 12v DC voltage-stabilizing electric current and two 12v, the quartzy white light of 50w-100w low pressure to, and two quartzy white lights place respectively the both sides in the lucifuge black box 2; Quartzy white light is apart from digital camera 1 optical center 20-40cm.The other end at lucifuge black box 2 is installed hair stationary cylinder 4, and hair stationary cylinder 4 is used for fixing tested bundle of hair, and hair stationary cylinder 4 is the black cylinder of diameter 5-8cm, long 10-20cm surface no-reflection, apart from digital camera 1 optical center 50-70cm.The center of digital camera, two quartzy white lights and hair stationary cylinder is in the same level height, all apart from 20-30cm at the bottom of the lucifuge black box 2 casees.Bundle of hair to be measured is at hair stationary cylinder 4 length direction upper berth broadening 2-10cm, and the long 20-40cm of bundle of hair carries out luminance test around the rear vertical sagging confession of hair stationary cylinder 4 one circles.
Measure the method for the hair gloss degree that exsomatizes among the present invention, comprise by digital camera 1 and take acquisition hair image, through the MATLAB image processing software hair image of taking is carried out data acquisition, output brightness curve, peak of curve, area under the curve.
The shooting aperture F value of digital camera 1 is set to 5.6-7.1 among the present invention, shutter speed is that 1/100s-1/10000s, light sensitivity ISO value are 100-800.
Image processing and data acquisition are among the present invention:
(a) the hair image of taking is processed via MATLAB software, the RGB system is converted to LAB chrominance space system;
(b) image after MATLAB software is processed is reduced into 0.1 times of original image, and again from downscaled images apart from limit, the left and right sides each 160-230 pixel, each 110-150 of bottom pixel place intercepts the topknot image on the distance, gets the cut-away view picture;
(c) program is got a little in vertical each pixel the cut-away view picture, and takes multiple measurements at each vertical height, averages, and obtains the average brightness value L of each vertical At The Height in the cut-away view picture;
(d) different vertically highly as horizontal ordinate in the cut-away view picture, take the L value of this vertical At The Height as ordinate, draw brightness curve figure, use peak value P and the area under the curve A sign hair gloss degree of brightness curve.
Beneficial effect of the present invention: the present invention is simple to operate, quick, can objectively measure the glossiness for the human body topknot of research purpose, can be used for different hair care products to the action effect evaluation of hair gloss degree.
