The manikin of using among the present invention is to utilize clothes institute of Donghua University from the U.S. (TC
2) the three-dimensional human body measurement system that introduces of company generates.The principle of this system is to utilize four cameras in front and back to collect the image of four width of cloth human body different azimuth simultaneously, the method of utilizing Moire fringe to interfere then calculates the three-dimensional lattice data of manikin, then utilize the three-dimensional lattice data to carry out the triangular surface match, obtain three-dimensional (3 D) manikin, carry out size at last and extract operation, the unit's of obtaining human dimension.
Fig. 2 is the interface of the three-dimensional garment piece design system of exploitation.
The data structure of using among the present invention mainly contains four kinds, comprises dot structure, limit structure, triangular structure, three-dimensional garment piece structure, and is as follows:
More than four structures are garment piece data structures of problem design, utilize the mutual ball of mouse and three dimensions to choose and control point on the manikin, with it as the borderline point of three-dimensional garment piece, related data structure in conjunction with design, obtain point, limit, the garment piece structure of three-dimensional garment piece outline line, then utilize the method for interpolation to generate point in the border, Delaunay trigonometric ratio then, generate the tri patch of garment piece, obtain complete garment piece.
Before generating three-dimensional garment piece, at first must generate the outline line of garment piece.In real work, matched curve commonly used has: cubic parametric SPL, Bezier curve, B-spline curves etc.; So-called curve fitting is meant in the curve design process, makes the curve of generation reach some requirement with the interpolation or the method for approaching, as pressing close to original data point or reference mark sequence in allowed limits; Look as curve and to want " smooth ", " fairing " etc.Bezier curve and B-spline curves are the parametric lines to approach, they have advantages such as directly perceived and convex closure, but they are general not by given feature polygon, the method of the heavy node of utilization only can make them pass through other point, therefore they are mainly used in the design of free type curve, though, also can make them pass through given data point, after all around a big bend by using their inverse approximating method [16-18]; The cubic spline interpolation curve of using among the present invention has directly used the method for interpolation to make matched curve pass through given data point, and has satisfied the requirement of line smoothing, can well satisfy the demand.Three-dimensional garment piece outline line is made up of straight line and curve, selected point and to generate corresponding garment piece structure be according to following thinking:
(1) if the limit is made up of two points, determines that then this limit is a straight line;
(2) if the limit, determines then that this limit is a curve by forming more than two points;
For straight line, 2 definite straight lines obviously; And for curve, what use in the system is the cubic spline interpolation method, by the last front cut pieces that it can generate, the boundary Control point have 14 1,2,3 ... 14}; The limit has 7, be respectively, line1{1 2}, line2{2 3}, line3{3 45 6}, line4{6 7}, line5{7 89 10}, line6{10 11}, line7{1112 13 1}, central point is 14.
Annotate: can arbitrary rotation and translation model and garment piece in the system, selected three angles herein.
As shown in Figure 4, be the preceding skirt sheet that system generates, the boundary Control point have 91,2,3 ..., 9}; The limit has 5, be respectively, line1{1 2}, line2{2 3}, line3{3 45 6}, line4{6 7}, line5{7 89 1}, central point is 10.
After obtaining the outline line of garment piece, obtain point in the garment piece by interpolation again.B.K Hinds and J.McCartney have introduced a kind of digitizer that utilizes and have realized three-dimension interaction in two pieces of articles that 1990,1992 deliver, generate to have the method for the three-dimensional garment piece of certain fit degree.Its detailed process is that digitizer is mapped to 3 D human body surface in the computing machine, the 3 D human body surface moves in the mobile corresponding computing machine on the digitizer, level of freedom is provided in addition, determine side-play amount (being defined as the distance of human body normal plane certain point outside human body, i.e. the fit degree offset of clothes) apart from people's platform surface.When generating three-dimensional garment piece, at first determine to have the each point on the garment piece sideline of certain deviation amount, the utilization curve fitting obtains each limit curve of garment piece, uses interpolation method to obtain the side-play amount of each point in the garment piece then, carries out the three-dimensional garment piece that surface fitting has just obtained meeting body shape.
The particular case of coupling system has developed a kind of new interpolation method, can obtain to meet each point in the human body surface tool garment piece at regular intervals by it, thereby obtains meeting the three-dimensional garment piece of body shape according to these points, and following mask body is introduced this algorithm:
Mutual ball of the three dimensions that utilizes virtual reality system VR3800L to provide (SPACEBALL) and mouse, acquisition is apart from some some I (1-14) of the surperficial certain distance of virtual human body, them as three-dimensional garment piece more borderline point and central points, as shown in Figure 5.This interpolation method is mutual ball of three dimensions (SPACEBALL) and the mouse that utilizes virtual reality system VR3800L to provide, acquisition is apart from some some I (1-14) of the surperficial certain distance of virtual human body, them as three-dimensional garment piece more borderline point and central points, point in the three dimensions has coordinate (x

i, z
i) be the point that interpolation obtains, (x
Mi, y
Mi, z
Mi) be the point on the model; Next step, suppose that human body surface is continuous, i.e. (x, the z coordinate of the point that y) closes on differs very little, then, replaces the z coordinate of corresponding interpolation point with the z coordinate of the point on the manikin of corresponding distance minimum, add corresponding spacing k, just obtained the point in the three-dimensional garment piece, and this is the garment piece with a fixed gap that meets human body contour outline, so just obtains (the x of the interior each point of clothing
i, y
i, z
i, k
i), be illustrated in fig. 6 shown below.
After the point that obtains by interpolation in the garment piece, with these Delaunay trigonometric ratios, the triangle relation between obtaining a little.The Delaunay trigonometric ratio is a kind of method at the discrete point trigonometric ratio, introduce Voronoi figure earlier: the Voronoi figure of one group of geometric object is divided into a series of intervals with codomain, the Voronoi figure of the point that each space comprises and some geometric objects is divided into a series of intervals with codomain, the point that each space comprises and the distance of some geometric objects are less than other geometric object, as shown in Figure 7.Given one group of planar point (1-10), the distance of the planar point that the point in each Voronoi polygon and each polygon comprise less than with the distance of other planar point; The triangle that the Delaunay trigonometric ratio obtains, and do not comprise given planar point in these leg-of-mutton circumscribed circles, the center of circle of circumscribed circle is the polygonal summit of Voronoi.
The Delaunay trigonometric ratio is the trigonometric ratio to two dimensional surface point, it is to three-dimensional interpolation point (x in system, y) coordinate carry out interpolationization, be equivalent to planar point (x, y) carry out trigonometric ratio, obtain their triangle relation, promptly a series of triangle, this triangle relation is applied on the three-dimensional point, has just obtained three-dimensional tri patch; As shown in Figure 8: the figure left side is the garment piece each point that interpolation obtains, in the middle of the figure is without improved Delaunay trigonometric ratio, by the trigonometric ratio of Delaunay shown in the figure acquiescence trigonometric ratio is carried out in the convex zone, some is positioned at the garment piece that is obtained by the trigonometric ratio of Delaunay shown in the figure outside the garment piece outline line, this is because Delaunay trigonometric ratio acquiescence is carried out trigonometric ratio to the convex zone, therefore for concave edge on the garment piece, the triangle that the Delaunay trigonometric ratio obtains has exceeded the border.In order to be met the triangular facet of garment piece outline line fully, in conjunction with the actual conditions of problem, the triangle that the Delaunay trigonometric ratio obtains has been done some improvement processing, removed the outer triangle of garment piece profile; Concrete Rule of judgment is if leg-of-mutton three summits all are positioned on the garment piece outline line, then this triangle is removed, and Fig. 8 right side is the garment piece triangular facet that obtains after improving.
As shown in Figure 9, be the last front cut pieces that obtains behind the Delaunay trigonometric ratio; As shown in figure 10, be the preceding skirt sheet that obtains behind the Delaunay trigonometric ratio; As shown in figure 11, be the back garment piece of going up that obtains behind the Delaunay trigonometric ratio.
The advantage of three-dimensional cutting is to design for plane cutting the relatively style of difficulty, such as adding pleat, wave, hanging down and style such as swing, is that present systemic-function also can't realize; As for dangling, when design system, also once considered on the basis of garment piece geometric model, generate the particle physics model of garment piece, thus the effect that obtains dangling, and this also is why to obtain the interior point of garment piece with the method for interpolation, trigonometric ratio generates garment piece then, interpolation thought by same also can reach the garment piece rectangular lattice, thereby can add particle model, therefore system's later stage can add the function of dangling, and just is subjected to the constraint of time and efforts at present, and this part work does not also launch; As for the variation of style, can reach certain requirement by the boundary Control point fully, be to meet the human body three-dimensional garment piece but this system generates by interpolation, relatively be fit to generate fit clothing, generate the clothes of loose class, possible effect is not very good, change a kind of interpolation method and could realize.
In sum, in virtual environment, utilize the mutual ball of mouse and three dimensions to choose and control point on the manikin, with it as the borderline point of three-dimensional garment piece, in conjunction with related data structure, obtain point, limit, the garment piece structure of three-dimensional garment piece outline line, then utilize the point in the specific interpolation method generation border, use improved Delaunay trigonometric ratio algorithm then, the three-dimensional garment piece that has obtained meeting human body surface and had certain voidage, the result is challenging.
