Background technology
At garment industry, the technological change of clothes industries has been quickened in the research and development of clothing CAD technology and applying.Especially at present be subjected to the influence of world's financial crisis, apparel industry is subjected to very big impact, is the reply existing situation, and China's textile garment industry export rebate rate reaches historical high, and country encourages the industrial upgrading transition of apparel industry.In this case, strengthen the garment technology transformation, promotion information combines with the clothes industry, quickens apparel industry and seems particularly important transition to technology-intensive direction.
CAD of Garment two dimension is to three-dimensional study on the transformation, is the focus and the difficult point of clothes research field.Carry out the commercialization technology that 3-D effect shows on computers in case solve, must will could observe the restriction of its effect after the garment sewing, make enterprise respond market fast, enhance competitiveness thoroughly changing in the present garment production.
At present, clothes 2D adopts the stitching principle on the Study on Transformation of 3D, indicate the corresponding position that to sew up between the garment piece and sew up the corresponding human body in back, keep sewing up the constant substantially two-dimentional garment piece of area without any attribute, consider the singularity of the three-dimensional contouring of turnover neck, the method for this apposition suture relatively is difficult to realize the spatial modelling effect of different turnover necks.And in the research for three-dimensional collar, too idealized for the geometric modeling of collar, with the corresponding shortage research of model, practicality is not very strong.
Summary of the invention
Technical matters to be solved by this invention provides a kind of feature and influence factor of passing through the three-dimensional contouring of analysis collar, extract the parameter of collar model structure, obtain the two-dimension parameter to three-dimension effect drawing data converted, and obtain mathematical model, on these bases, use MATLAB to develop the visualization conversion method of the two-dimension parameter to three-dimension effect drawing of collar, this method can make collar not need just to make out to see its effect, for significant exploration has been made once in clothes two dimension to the CAD of Garment exploitation of three-dimensional conversion.
The technical solution adopted for the present invention to solve the technical problems is: a kind of clothing collar two-dimension parameter to three-dimension effect drawing visualization conversion method is provided, determine that section triangle is that the collar two dimension is to three-dimensional Bridge, described method adopts computer operating system, comprises the following steps:
(1) set up collar two-dimensional structure parameter: based on collar model architectural feature, extract its two-dimensional parameter: play rake angle and neck angle of release, collar model structure is carried out parametric description, it is the basis that the extremely three-dimensional digitizing that transforms of collar two dimension is expressed;
(2) two dimension of setting up collar is changeed three-dimensional model: two-dimensional parameter characteristic of correspondence size is converted into the three dimensions mo(u)lding line of collar, realizes that the three-dimensional modeling space digitizing of collar is expressed;
(3) set up collar two dimension surface interpolation model: accept one group of two-dimensional parameter,, export the characteristic dimension of the collar three-dimensional modeling under the corresponding parameter according to rule to the processing gained of existing experimental data collection;
(4) the visual conversion output of collar two-dimension parameter to three-dimension effect drawing: this system is according to two above models, and by the interactive function of MATLAB, the two-dimensional parameter in the input parameter scope can obtain the 3 d effect graph of corresponding turnover neck.
Described computer operating system adopts the Windows system, and drawing instrument adopts MATLAB, and the program development platform is MATLAB, and described MATLAB can realize the contrast display effect of different collar.
Described collar comprises two kinds of eckband shapes of U, V.
The present invention is by analyzing the characteristics and the influence factor of the three-dimensional contouring of turnover neck, determine that section triangle is that the collar two dimension is to three-dimensional Bridge, extract two-dimensional result parameter-neck angle of release and rake angle and describe the planar structure of collar, obtain the experimental data of two dimension by the ready-made clothes experiment and the dressing experiments of measuring of collar then to three-dimensional conversion, the line data analysis of going forward side by side, set up mathematical model, selecting the MATLAB with powerful numerical analysis and graphical display function on this basis for use is development platform, design has also been developed the visualization system of changing to 3 d effect graph based on the turnover neck two dimension of GUI, has realized the visualization display of random two-dimensional parameter to its corresponding three-dimensional design sketch.The present invention is a kind of realization of method for transformation, and the technological means that realizes has substitutability.
Beneficial effect
The present invention proposes a kind of new two dimension to three-dimensional conversion method, realized the method for visualizing of the two dimension of collar, significant exploration has been made once in the research of clothes 2 d-to-3 d conversion to the 3 d effect graph conversion, for collar
The research of 2 d-to-3 d replacement theory provides a brand-new window, has bigger theory and is worth and practical value.
