Step 6-3, the touching display screen of three-dimensional dressing system is according to the left point coordinates of gained shoulder breadth, the right point coordinates of shoulder breadth, waistline Left point coordinates and the right point coordinates of waistline, are calculated the maximum distortion deformation region of restriction；Wherein, the maximum distortion shape of restriction It is Region to become zone marker_max：

$\left\{\begin{array}{c}{\mathrm{Region}}_{\max \_x}=\frac{(x_{Waist-L}-x_{Waist-R})+\left(\frac{x_{Waist-R}-x_{Shoulder-L}+1}{2}\right)+\left(\frac{x_{Waist-L}-x_{Shoulder-R}+1}{2}\right)}{|x_{Waist-L}-x_{Waist-R}+1|}-1\\ {\mathrm{Region}}_{\max \_y}=\frac{(y_{Waist-L}-y_{Waist-R})+\left(\frac{y_{Waist-R}-y_{Shoulder-L}+1}{2}\right)+\left(\frac{y_{Waist-L}-y_{Shoulder-R}+1}{2}\right)}{|y_{Waist-L}-y_{Waist-R}+1|}-1\\ {\mathrm{Region}}_{\max \_z}=\frac{(z_{Waist-L}-z_{Waist-R})+\left(\frac{z_{Waist-R}-z_{Shoulder-L}+1}{2}\right)+\left(\frac{z_{Waist-L}-z_{Shoulder-R}+1}{2}\right)}{|z_{Waist-L}-z_{Waist-R}+1|}-1\end{array}\right.;$

The region that the virtual costume fitting model is taken up an official post at meaning point (x, y, z) is satisfied by

Step 7, fitting person is input into the fitting background image title to be worn of the try-on garment by central processing unit, and by trying Clothing Background generation device generates corresponding fitting background image；Touching display screen carries out depth to the fitting background image for being generated Pretreatment, the selected fitting background image of fitting person is shown with high-resolution；Wherein, fitting of the touching display screen to being generated The process that background image carries out depth pretreatment is：

By the edge some pixels of expansionism in the horizontal direction of the fitting background image, to cause fitting background image surface On depth value reach unanimously, and then avoid causing the geometric distortion of fitting background image；Wherein, the edge of fitting background image The expansion model of expansionism is in the horizontal direction：

$d^{\&prime;}(x+dir(x,y)*h,y)=\{\begin{array}{ccc}d(x,y)& dir(x,y)=-1& h=0,1,\mathrm{...},K\\ d(x+1,y)& dir(x,y)=1& h=0,1,\mathrm{...},K-1\end{array};$

Wherein, d (x, y) represents gray level of the pixel at coordinate (x, y) place on fitting background image before edge expansionism, D'(x, y) gray level of the pixel at denotation coordination (x, y) place after edge expansionism, dir (x, y) represents fitting Background As the direction of upper coordinate (x, y) expansionism；1 representative is expanded to the right in the horizontal direction, and -1 representative is expanded to the left in the horizontal direction, Any expansion is not done in 0 expression in the horizontal direction；K represents the number of pixels value of coordinate (x, y) expansionism on fitting background image；

Th is directed to for touching display screen The predetermined threshold value constant that the selected fitting background image of fitting person is pre-processed；

Step 8, fitting person is being satisfied with virtual costume fitting model with the actual dynamic model of human body in selected fitting background image Under try situation on after, the satisfied instruction of fitting person input fitting is joined to central processing unit by central processing unit order dress form Number database transfers the current clothes parameter feedback fitted corresponding to satisfied instruction to fitting person, so that fitting person is according to feedback Clothes parameter acquiring is corresponding to be satisfied with clothes.

2. the three-dimensional fitting method based on body-sensing characteristic parameter extraction according to claim 1, it is characterised in that in step Also include after 8：

Step 9, after the satisfied instruction of fitting person input fitting is to the central processing unit of three-dimensional dressing system, three-dimensional dressing system is touched Touch the display of formula display screen and inquire whether fitting person obtains each one corresponding to the prompting frame and the fitting person of clothes effect model The actual dynamic model of body, and after fitting person selection obtains the instruction of clothes effect model, shown by touching display screen and paid Fund is prompted to fitting person；

Step 10, three-dimensional dressing system prestores embedding close image zooming-out key in banking system, in fitting person by touch After being input into bank's card number and corresponding payment cipher on display screen, touching display screen continuously acquires the fitting person preset number Fitting person face-image treat embedding close original image as this delivery operation, with the fitting person with unique biological characteristic Face-image is used as preliminary safe encryption measures, and the payment information including bank's card number and payment cipher to being received enters Row is based on the embedding close Hybrid Encryption of image, to obtain embedding close image, and will be embedded in embedding close image by touching display screen Payment information is safely supplied to corresponding banking system to be decrypted；

Step 11, the embedding close image zooming-out key that banking system prestores according to three-dimensional dressing system, extracts embedding close fitting person Payment information in face-image, banking system judges the branch that extracted payment information prestores with fitting person in the banking system When the information of paying is consistent, banking system completes withholing and silver to fitting person bank account according to the embedding close image zooming-out key that prestores Row system is transferred accounts to three-dimensional dressing system account.

3. the three-dimensional fitting method based on body-sensing characteristic parameter extraction according to claim 2, it is characterised in that step 11 Also include afterwards：Three-dimensional dressing system confirm receive fitting person payment after, life of the 3D printer according to central processing unit The order printing fitting person actual dynamic model of selected human body, to print 3D moulds during try-on garment corresponding to fitting person dress Type, and the actual body-sensing characteristic parameter of the fitting person is supplied to fitting person by the three-dimensional dressing system, to facilitate fitting The actual body-sensing characteristic parameter of oneself is exported to three-dimensional dressing system when person fits again.
