1. the three-dimensional female body automatic generation method based on female body component model and body-contoured is characterized in that, concrete steps are as follows:

  • (1) the female body front that is provided by the client, side two width of cloth two-dimensional numerals photos and female body bodily form feature information extraction rule, acquisition client'"'"'s direct bearing, side coil body-contoured information and bodily form geometric properties information;

    Described two-dimensional numerals photo extracts female body bodily form characteristic information rule;

    at first client'"'"'s two width of cloth two-dimensional numerals photo application digital image processing method positive, the side is obtained its direct bearing, side coil body-contoured, then adopt the crucial cross-section bit position of the preliminary automatically location of ratio female body at each position of female body in the GB " clothes female body measuring point and method ", then according to the geometric properties at each position of female body these positions are finely tuned, extract female body bodily form characteristic information according to these positions;

    (2) set up female body component model series;

    After gathering a series of female body samples by spatial digitizer, according to the standard customization female body component model series of female body bodily form tagsort rule and women'"'"'s bodily form tagsort method;

    Wherein women'"'"'s bodily form tagsort method has three grades of classifications, and the one-level classification is by national bodily form criteria classification, and classificating word is;

    Y, A, B, C;

    Secondary classification is divided into by the generous ratio classification in the principal section of its chest, waist, three figures of stern;

    circle, in, flat;

    Reclassify is pressed the breastheight value classification in chest cross section, is divided into;

    high, medium and low;

    Then in its classification results, extract and be positioned at the sample of median as the female body component model of respective classes;

    Described female body bodily form tagsort rule is;

    the female body parts are divided into three figures;

    chest figure, waist section, stern figure;

    Each figure is further divided into one group of crucial cross section, and wherein, the chest figure is divided into the chest cross section, upper chest cross section, the lower breast cross section, shoulder cross section, front throat area and rear throat area, the waist section is divided into waist cross section and abdomen cross section, the stern figure is divided into stern cross section and shelves cross section, and defines a principal section in each figure, and the principal section of chest figure is the chest cross section, the principal section of waist section is the waist cross section, and the principal section of stern figure is the stern cross section;

    (3) by client'"'"'s bodily form geometric properties information, by " female body component model apolegamy rule ", from female body component model series, match out each figure cross section component model of corresponding women client'"'"'s human bodily form;

    Described female body component model apolegamy rule is;

    the generous ratio of each the figure principal section of female body bodily form geometric properties information acquisition that provides according to the client, and mated by the generous ratio of the principal section of corresponding figure template in these ratios and the female body component model series, match out the immediate figure of ratio, if the chest figure is further determined selected chest figure by the breastheight value;

    Each figure parts of matching have comprised one group of crucial cross section, adopt female body component model apolegamy rule can obtain three figures and ten crucial cross sections;

    (4) the female body bodily form characteristic information that provides according to the client, use " based on the female body component model alteration ruler of cross section profile control ", female body component model to apolegamy is made amendment, and makes the cross section profile characteristic parameter of women'"'"'s human part template meet client'"'"'s bodily form geometric properties information;

    Described female body component model alteration ruler based on cross section profile control is;

    width and one-tenth-value thickness 1/10 according to each crucial cross section in women client'"'"'s human body figure carry out proportional zoom to each corresponding crucial cross section in the female body component model of apolegamy respectively, consequently the crucial cross section profile of amended female body component model is similar to client'"'"'s crucial cross section profile shape, and its width is identical with the value in the corresponding crucial cross section of client'"'"'s human body with one-tenth-value thickness 1/10;

    (5) with two body-contoured of client'"'"'s direct bearing, side coil of extracting location assembling frame as female body parts after revising, this framework determines the volume coordinate position of female body parts;

    different figures and cross section parts place respectively the correspondence position of this framework, determine the z coordinate of female body positioning parts with this;

    With the center line of the client'"'"'s direct bearing body-contoured positioning datum as parts x direction center, cross section;

    With the bent gesture line of the customer side orientation body-contoured positioning datum as parts y direction center, cross section;

    Amended female body component model is assembled by positioning framework, and consequently the bent gesture of the female body that provides of the location of female body component model and client is consistent;

    (6) adopt the nurbs surface fitting technique to generate the three-dimensional female body that the VRML form shows to the female body component model behind modification and the location.
