BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a clothes pedestal used in the process of designing and manufacturing clothes adapted to a group of people who are classified into different types. Method and apparatus for manufacturing a full-size pedestal of a size, and a reduced-size pedestal of a half or a quarter suitable for reducing the required cloth and reducing the space used. And a device therefor.

2. Description of the Related Art In the first place, both a full-size stand and a reduced-size stand mainly used in student classes are extremely important tools in the process of designing and manufacturing clothes, and are widely used. These full-size and small-sized tables are already provided by hand.

[0003] In the learning of clothing production, a drawing is drawn from clothes designed and imaged on a desk using a two-dimensional prototype of an original size or a two-dimensional prototype of a reduced size (generally a quarter size). Later, based on this drafting, we formed and understood the drafting theory.

[0004] Regardless of the original size of the original size, it is convenient to use a reduced size original because the work space required for learning can be reduced. Since it is not possible to wear the garment, it is difficult for the learner to grasp the three-dimensional image when worn on the body, and there is a fatal drawback that the design tends to depend only on the dimensions.

[0005] Therefore, as described above, a hand-made reduced-size bed has been provided.

[0006] This hand-made reduced-size stand allows a person to cut out and draw a three-dimensionally shaped drawing from the drawing of the reduced-size prototype so that the user can clearly grasp the shape of the human body. In addition, it is possible to confirm three-dimensionally important items such as the state of the gap with the human body, the overall form, the balance of the structure line, etc., in a three-dimensional manner, and more accurately and efficiently drawing clothes. It is also possible to realize theoretical education, and because it is a reduced size, the occupied area is also small, it can be used without expanding the work space used for previous learning, it is easy to carry and the burden on the learner is reduced It had various effects, such as not being used, and was extremely useful.

[0007] However, the above-mentioned full-size and small-sized pedestals are manually formed from dimensions based on experience, and therefore, the three-dimensional morphological characteristics of the actual human body are not necessarily reflected. The problem is that the design and production for the production of these full-size and small-sized tables are time-consuming and not easy. was there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment (hereinafter, referred to as a first embodiment) for obtaining a full-size clothing stand according to claims 1 and 4 will be described with reference to the drawings. That is, a three-dimensional measurement unit that measures the actual body shape from the neck to the thighs of many subjects and inputs it to the computer, and correlates the individuals of the body shape data with reference to the feature points of the body. Modeling processing unit, three-dimensional morphological analysis and average morphological processing unit for classifying (grouping) body morphology and calculating average morphology using computer graphic technology, and more precise data for average morphology A precise form data conversion processing unit that converts the data into a form, a materialization processing unit that materializes the average form data on the computer by stereolithography, and a work completion processing unit that manufactures a work base using the materialized form as a model. , Consisting of

Before the measurement, the three-dimensional measurement unit finds the anatomical feature points shown in FIGS. 1 and 2 by touching and applies a mark in advance, and then projects the mark on the body surface. Using a three-dimensional shape measuring device 3 of the type described below, which captures the slit light with a CCD camera and measures the shape, the body shape from the neck to the thigh of many subjects is underwear such as a bra and soft girdle. The body shape measurement data is obtained by measuring with the left and right upper limbs open about 15 degrees in order to prevent data loss on the side of the trunk and wearing the body shape measurement data, and the body shape measurement data required for later processing Feature points that are picked with the mouse to the feature points on the body surface for clipping processing to cut out unnecessary parts of It is obtained to perform the work.

The three-dimensional shape measuring device 3 accurately measures the three-dimensional shape of the human body in a short time, and processes the body sway data which appears due to the subject's slight shaking and the posture being not constant, in a form suitable for the condition. In addition, the corrected three-dimensional shape data (absolute position information) is obtained. In this case, since the portion not exposed to the laser, such as the base of the arm or the crotch region, is an unmeasurable region, for these, the plaster obtained by the plaster bandaging method and the plaster obtained by the plastering method are used. The FRP is poured into the mold to form a human body shape mold, and thus the shape of the base of the arm or the crotch is acquired, and the body shape measurement data is obtained based on this.

The three-dimensional morphological analysis and average morphological processing unit performs a modeling process for associating individuals of the morphological data of the body with reference to the characteristic points of the body. Extracting the determined cross-sectional shape, projecting and printing the body coordinate system reference point and the feature points of the body on this, printing, dividing the printed cross-sectional view based on the feature point position projected on the cross-section, Modeling base data (see Fig. 3) is created by picking the points of division with a software digitizer running on a personal computer and obtaining a calculation sheet for projecting onto the coordinate axes in the direction of feature points and a coordinate point determination calculation sheet based on the actual size ratio. I do.

In the process of creating the modeling base data, a body shape characteristic appears, and a data that can be determined to be a data body with good data accuracy and good balance is selected from the above-mentioned body shape shape measurement data, and more accurate. Data that gives a high average shape result is selected, and for this selected body type, the distance between the shapes is mutually calculated, the distribution is determined, and the median is determined. Then, the average of a plurality of three-dimensional shapes schematically shown in FIG. The average form is calculated by applying an FFD control grid from the median form to another form using the form generation apparatus. The average form calculated in this way is several hundred polygons. Only a coarse average morphology is obtained with a coarse degree. It is not practical as it is,
As described below, the precise form data conversion processing unit prepares a new precise median form data (tens of thousands of polygons) and applies the FFD conversion grid to the mean form to deform the mean form. It is desirable to obtain.

To obtain the precise average form, the median form data is manually divided into horizontal sections with a pitch of about 3 mm, read by a scanner, and the image data is read by a dedicated software into a number of points in the section. (Coordinate data)
By stacking up to a large number of these to generate precise median data, trace all sections manually with a mouse, digitize the trace version with image software (image data),
In addition, the inconsistent parts and correction points required for balance are corrected by moving the screen, the contour of the cross section is smoothed, and the precise median form is obtained by checking the lamination state of the shape. A precise average form is obtained by applying an FFD conversion grid that converts a value form into an average form. Since the obtained average morphological data is not always a horizontal cross-section laminated by the averaging process, it is necessary to re-convert the data into horizontal cross-section laminated data in order to realize stereolithography described later. For this purpose, horizontal section data (coordinate point data) having a pitch of 2 mm is generated using horizontal section processing software, and is converted into image data using software in order to convert the data into data for an optical shaping apparatus. Confirm the data of each section. In this way, preprocessing is performed to bring a precise average form into stereolithography. .

The materialization processing unit converts the cross-sectional shape data into data for the optical shaping apparatus, and materializes the data on the basis of the data to produce a base mold (see FIG. 4).

The pedestal completion processing section obtains a completed product (not shown) based on the pedestal base 4 having an average and beautiful balance based on the actual side data.

Next, a description will be given of an average form generating apparatus having a plurality of three-dimensional forms schematically shown in FIG. That is, the apparatus comprises a computer 1 for calculating an average form from form data converted into numerical data and an optical shaping apparatus 2 for realizing the average form. The form data is input, and the stereolithography apparatus 2 generates a materialized average form.

In the computer 1, the Free
Form Deformation method (hereinafter FFD)
Method) is used. In the present invention,
Using this FFD method, the distance between the forms is calculated, a form corresponding to the median is selected from among them, and a control grid point movement pattern for converting the form from the median form to another form is averaged. Is applied to the median form and transformed to obtain an average form.

The apparatus 3 generates average morphological data representing a plurality of three-dimensional morphological data, and applies this to the generation of body morphological data from the neck to the thigh of the subject, thereby obtaining the average morphological data. By utilizing the design of the pedestal that associates with a person, it becomes possible to design a pedestal that can be associated with many forms of people without bias.

Also, in the stereolithography method, a laser beam is used to irradiate a laser beam in the form of cross-sectional data using a resin that is instantaneously cured by irradiating the laser beam. Methodology. Thereby, the average form (form that does not actually exist) calculated in the computer can be substantiated.

In the above-described embodiment, the average form is realized by using a stereolithography method (RapidPrototypin).
g), but methods other than this stereolithography, such as a cutting method using a numerical control plate, a type of laminating paper, an ink jet method, a powder laminating method such as starch, and other methods are also used. It goes without saying that you can do it.

In this connection, a reduced-size bed of a size such as one-half or one-fourth according to the second, third, fifth, sixth or seventh aspect is obtained, for example, through the actual body shape of the subject. The three-dimensional shape data for the original size by the three-dimensional shape measuring device 3 may be divided by the scale factor, or through a method of manufacturing a stand according to claim 1 or a person of the original size completed in advance by the manufacturing device according to claim 4. 3D shape measuring device 3 obtained
The scale data is created on the computer by dividing the original three-dimensional shape data by the scale factor, or dividing the cross-sectional shape data used by the materialization processing unit by the scale factor, and using the scale data. Then, following the above-described first embodiment, it was possible to carry out the same steps. Therefore, detailed description is omitted.

Since the present invention is as described above, according to the present invention, it is possible to easily and easily obtain a full-size bed of the same size as the actual one, and reduce the required amount of cloth and the space used. It is also possible to obtain a small-sized base such as one-half or one-fourth, which is suitable for, and obtains a more accurate and more stable base than a conventional base by hand. The present invention has an excellent effect of completely achieving the intended purpose of providing a new method of manufacturing a base and a device therefor.
