Specify the present invention below in conjunction with concrete data.
Utilize the non-contact 3-D body-scanner to scan and obtain the human body surface data.Select the East China, 18-24,25-29, four age bracket women of 30-34,35-40.
The selected three-dimensional human body measurement of the present invention system is U.S. TC
2The non-contact type human body measuring system that company develops, it comprises body scans and two main functional modules of anthropological measuring.The body scans module utilizes white light source at human body surface projection sinusoidal curve, and sinusoidal curve produces phase differential along with the irregular variation of body surface shape, thereby reflects the body surface form of human body.System scans human body from four orientation, at first obtains one group of topography, after testing after, system is merged into a complete human body image with this group topography automatically, obtains the data of 300,000 points of body surface, precision is in 0.06mm.The anthropological measuring module utilizes the size extraction software of special exploitation can extract more than 180 dimensional data of human body on the basis of the data point of body scans.
Determining of anthropological measuring sample size, generally speaking, stipulate in statistics that n＜30 are small sample, n＞30 are large sample.For general anthropological measuring, because age and regional span are very big, so within the specific limits, sample size is big more in principle, statistics is accurate more, and the present invention is chosen to be the area, Shanghai, and age bracket is decided to be 18-40 year woman, research range is all relative with age bracket less on the region, so in the light of actual conditions sample size is done following calculating.
According in country's type standard to learning in the human dimension sample survey, the measurement index of partes corporis humani position is obeyed approx just too and is distributed, and gets confidence level α=5%, the sample limiting error
Wherein, σ is a standard deviation.When getting α=5%, promptly measuring the sample fiducial probability is 95%, looks into the Standard Normal Distribution table, and getting the t value is 1.96, and the substitution following formula draws:
Guarantee error relatively
Draw thus:
Opening radical sign draws:
If the cv value is the coefficient of variation, it weighs the individual and overall divorce degree of sample.Its computing method are sample standard deviation and the ratio of sample average, that is:
Finally draw:
The value of A is followed following principle:
1-2%: be applicable to major research item;
3-4%: be applicable to general scientific research;
5%: be applicable to commercial production in enormous quantities
According to the method for building up of industrial people's platform of the present invention, the minimum A of the choosing value of the present invention is 2%, and in order to reach bigger degree of accuracy, it is 1% that the present invention selects the A value.CV is the coefficient of variation, the difference degree of expression statistic.Its computing method are that standard deviation is divided by the statistic mathematical expectation.Utilize the related mainly measurement project of human body of national garment size standard to carry out determining of CV value.Its data are as shown in table 1 below:
| The position | Height | Cervical vertebra point is high | The waist height | Chest measurement | The neck rhizosphere | Shoulder across | Waistline | Hip circumference |
| C·V | 0.039 | 0.0431 | 0.0562 | 0.0735 | 0.0536 | 0.0996 | 0.0996 | 0.0504 |
Table 1
According to the numerical value of CV shown in the table 1 as can be known, the accuracy requirement of waistline is higher, because mainly consider waistline, if can meet the demands for the precision of waistline, then the precision of other indexs also can be met.Be calculated as follows n=1.962*0.09962/0.012=381, regular is 400.So the method for building up of industrial people's platform of the present invention, the n of sampling amount preferably of human sample is 400.This sampling amount satisfies the needs of clothes research fully.
The East China is selected in anthropological measuring of the present invention, and the East China is the clustering area of Chinese costume brand, also is the cradle of Chinese trendy product.Certainly, other areas also can be set up industrial people's platform in its area by identical method.
The present invention selects 18-24 year, 25-29 year, 30-34 year and 35-40 year four age brackets classify.Its main cause is the restriction of anthropological measuring cost and objective condition, the reason of human body growth rhythm and the reason of garment market etc.In like manner, other age brackets also can carry out the foundation of industrial people's platform by identical method.The method for building up of industry people platform is not subjected to the influence of area or age bracket, applicable to any one location, and any age.
Pass through TC
2The anthropological measuring module of three-dimensional human body measurement system can be discerned automatically, analyze, calculate the data that scanning obtains, and reports out the length and the latitude dimensional data of partes corporis humani position, can obtain 268 dimensional datas altogether.
Because the present invention is mainly used in garment industry, so selected 45 of direct measurement projects on the measuring point, comprises the data such as height (length), degree of enclosing, width, thickness and angle of human body, and is as shown in table 2.

Table 2
According to the human body information of wanting required for the present invention, more than 45 item numbers according to not embodying the feature of buman body type completely, thereby direct measurement data is transformed by some algorithm, can obtain indirect project participate in data analysis with to 15 of the descriptions of trunk feature, as shown in table 3.
Table 3
More than 60 measurement projects can satisfy the clothes research needs of industrial people's stage body type fully.
The present invention selects 18-24 year, 25-29 year, 30-34 year and 35-40 year four age brackets classify.Its main cause is that all ages and classes has very big difference on build, thereby forms the clothes classification of different size; All ages and classes section women has bigger difference on the dress ornament demand simultaneously, in the segmenting market, clothes usually the women is divided into maiden (phase adolescence 15-17 year), Miss (love and marriage phase 18-24 year), young married woman (maturity stage 25-34 year), middle age (without doubt phase 35-44 year), they have nothing in common with each other to the requirement of dress ornament, and the maiden who is in phase adolescence requires style vivaciously fresh, dazzlingly beautiful, changeable; The Miss who is in the love and marriage phase follows the fashion, and it is higher that dress ornament is appreciated taste, and dress ornament U.S.A is had strong request and motivated; Maturity stage young married woman appreciation level height has unique opinion to clothing; The middle aged women of phase without doubt is then refined and unique, and pretty and not gorgeous, selecting then to dress ornament, standard tends towards stability.The present invention is a single factors with the age by one-way analysis of variance, choose height, degree of enclosing, width, thickness totally 24 indexs four age bracket women's build is compared analysis, as shown in table 4.
Table 4
By average as can be seen, with advancing age, the numerical value of each height project of women is descending, degree of enclosing respectively, and width, the value of thickness project is increasing; Prominent amount increases gradually with the growth at age before the abdomen, and the prominent amount of stern then descends gradually.The F assay shows, height, and cervical vertebra point is high, hip breadth, the conspicuousness of four projects of the prominent amount of thoracic dorsal is respectively 0.128,0.138,0.062,0.327, and it is worth all greater than 0.05, shows four age bracket women builds there was no significant difference on these four projects; All the other project conspicuousnesses illustrate that all less than 0.05 the conspicuousness change all takes place these projects with advancing age, and wherein waist and belly is especially remarkable with advancing age.
So with 18-24 year, 25-29 year, 30-34 year and 35-40 the year four age brackets needs that not only meet garment market age location of classifying also match with the size differenceization of all ages and classes section female body.
Because women's build still has very big difference in each age bracket, the present invention is divided into Y, A, four kinds of builds of B, C according to country's type standard with female body, is the criteria for classifying with chest waist difference.As shown in table 5ly be:
Table 5
