DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a portrait model according to the present invention. The portrait model 1 is obtained by transferring a face photograph 3 on the surface of a face model 2 as shown in FIG.

[0006] The face model 2 and the face photograph 3 are three-dimensional images obtained by photographing the face of a target person with a three-dimensional camera capable of simultaneously inputting three-dimensional shape data and image data. It is made based on shape data and image data. The three-dimensional data and image data obtained by shooting are transferred from the 3D camera to the computer. The computer is connected with a numerically controlled machine tool and a printer.

[0007] The numerically controlled machine tool is equipped with a cutting tool such as an end mill. The relative motion between the cutting tool and the workpiece 4 set on the numerically controlled machine tool is determined by the position and speed based on three-dimensional data. It controls by numerical information such as, and executes a series of operations related to machining. The workpiece 4 is formed of a plastic or foamed plastic material suitable for cutting, such as wax-type resin, chemical wood, or hard foamed polyurethane, which is formed in a rectangular parallelepiped. Then, the numerically controlled machine tool cuts the workpiece 4 based on the three-dimensional data, forms a prototype 5 of the face model 2, and performs a casting method using a molding die 6 formed based on the prototype 5. The face model 2 shown in FIG. 2 is molded, that is, a liquid resin (a resin which is prepared so as to be cured after a certain period of time and has heat resistance after curing) is injected into a molding die 6, and after the liquid resin is cured, The mold is removed and the face model 2 is formed.

As shown in FIG. 6, a background image other than the face image 7 is erased from the image data by computer operation, and the outline of the face image 7 that has not been photographed, ie, the top, the temporal, The face image 7 is modified by extending the cheeks and lower chin with a shade corresponding to the color scheme of each part.
Is printed in color on transfer paper 8 by a printer (see FIG. 7). The transfer paper 8 is formed on a water-permeable mount 9 on a water-soluble adhesive layer such as dextrin or polyvinyl alcohol, a thermosetting adhesive layer such as an unsaturated polyester resin or an epoxy resin, a polyester-based resin, or vinyl acetate. And a synthetic resin film layer having good compatibility with a toner for forming an electrophotograph such as a copolymer of vinyl chloride and vinyl chloride. It is formed on a synthetic resin film. Then, the transfer paper 8 is immersed in water or warm water to dissolve the water-soluble adhesive, and a face photograph coating 10 on which the face photograph 3 is printed on the front surface from the mount 9 (a synthetic film having a thermosetting adhesive on the back surface). After the resin film) is peeled off and the face photographic film 10 is brought into close contact with the face model 2, after drying, the thermosetting adhesive is thermally cured in an electric furnace to fix the face photographic film 10 on the face model 2. Let me.

A decorative body W may be attached to the face model 2. Hereinafter, a specific example of the decorative body W will be described. As an example, a head model 12 is formed by bonding and integrating an occipital model 11 formed corresponding to the face model 2, and as shown in FIG. Then, it is used as a decoration for the strap or key holder of the mobile phone. As another example, as shown in FIGS. 9A and 9B, a whole body model 15 is formed by attaching a torso model 14 having movable joints to the head model 12, as shown in FIGS. 9A and 9B. As shown in the figure, a doll is formed by attaching a costume costume 13 to a full-body model 15.

Next, a method of manufacturing the portrait model will be described below in the order of steps. (1) Photographing step The face of the target person is photographed with a 3D camera,
The dimensional shape data and the image data are input simultaneously. Then, the three-dimensional shape data and the image data are transferred to the computer. As the 3D camera, a product name "virtuoso" manufactured by Visual Interface (USA) is used. If the camera has a function capable of simultaneously inputting the three-dimensional shape data and the image data of the subject, this is used. It is not limited to.

(2) Prototype Forming Step The prototype 5 of the face model 2 is cut by a numerically controlled machine tool based on the three-dimensional shape data obtained in the photographing step. Due to such cutting, as shown in FIG. 3, the workpiece 4 has a prototype 5 of the face model 2 based on the three-dimensional data in the center thereof.
It is embossed in the center of the concave portion 4a that has been depressed into a square shape.

(3) Molding Step A mold 6 is formed based on the mold 5 formed in the mold forming step. First, liquid silicone rubber mixed with a curing agent is poured into the concave portion 4a of the workpiece 4 and crosslinked. After the liquid silicone rubber is solidified, it is released from the workpiece 4 to form a first mold 6a having a concave face as shown in FIG. First mold 6a
Is a second type having a precise molding surface because its molding surface is rough.
Mold 6 (the drawing is omitted because it has substantially the same shape as that of FIG. 4;
Are shown in FIG. 4 by numbers in parentheses. ). The molding method is performed as follows. First, a liquid resin is poured into the molding surface of the first molding die 6a, and after the liquid resin is cured, it is released from the mold to form the second prototype 5a of the face model 2. This second
The surface of the prototype 5a is surface-treated by applying a filling agent to fill the micropores on the surface of the prototype 5a.
Smooth the surface of 5a. Next, as shown in FIG. 5, the prototype 5a is fixed to the center of the bottom of the square box-shaped mold 16 with an adhesive, and the mold 5a and the mold 16 are integrated. And formwork 16
The same liquid silicone rubber as above is poured into the inside and solidified. Thereafter, the mold is released to form a second mold 6 (hereinafter, simply referred to as mold 6).

(4) Facial model molding step A liquid resin is poured into the molding surface of the molding die 6, and after the resin is cured, the resin is removed and the facial model 2 shown in FIG. 2 is molded.

(5) Image processing step Image data obtained in the photographing step is processed by a computer. In this image processing, image data is displayed on a display of the computer by a computer, background images other than the face image 7 in this display area are deleted, and the outside of the outline of the face image 7 that is not photographed, that is, the vertex, the temporal region, The part, the cheek, and the lower chin are corrected by adding a color in accordance with the color scheme of each part so as to be extended within the range of the image display area.

(6) Photographic printing process A facial photograph 3 based on the facial image 7 image-processed as described above.
Is printed in color on transfer paper 8 by a printer (see FIG. 7).

(7) Face photograph transfer step The transfer paper 8 is immersed in water or warm water, and the face photograph
Peel 10 off. Then, the face photographic film 10 is attached to the face model 2 such that the respective parts such as eyes, nose, and mouth in the face photograph 3 on the face photograph film 10 correspond to the respective parts of the face model 2 respectively. Note that a solvent such as ethylene glycol monobutyl ether may be applied to the surface of the face model 2 in order to enhance the adhesion with the transfer paper 8. Since the face photograph 3 in the face photograph coating 10 only shows a planar face, for example, the nose area of the face photograph 3 does not slightly correspond to the three-dimensional surface area of the nose of the face model 2. But face photo film 10
Is made of a synthetic resin film, so that it can be stretched by applying warm water. When applying the face photograph coating 10, while applying warm water to each part of the face photograph 3 in the face photograph coating 10 on the face model 2, The face photographic film 10 is slightly stretched and applied so as to correspond to the uneven shape of the model 2, such as the eyes, nose, and mouth. Also, in the face photograph 3 on the face photograph coating 10, the portion modified by image processing is applied so as to correspond to the side 2a of the face model 2 (top of head, temporal region, cheek, and lower chin). Attached. After the face photograph 3 is transferred to the face model 2 as described above, the face photograph 3 is air-dried, and then the adhesive is thermally cured on the back surface of the face photograph film 10 in an electric furnace, so that the face photograph film 10 is exposed to the face. Settle on model 2 (Fig. 1
reference). Thereafter, in order to protect the surface of the face model 2, a transparent coating agent is applied on the surface (the face photograph 3) of the face model 2 to form a protective film. Note that this coating agent is limited to one that does not dissolve the toner that forms the face photograph 3 on the face photograph film 10.

(8) Facial model decoration step An occipital model corresponding to the facial model 2 produced as described above
Prepare 11 The occipital model 11 is formed in advance in a size corresponding to the facial model 2 by a casting method, and is made of the same material as the facial model 2. And
The head model 12 is formed by bonding and integrating the flat portions on the back surfaces of the face model 2 and the occipital model 11 with an adhesive.
Then, as shown in FIG.
Attach 13 and use it as a decoration for the strap or key holder of the mobile phone. Alternatively, as shown in FIGS. 9A and 9B, a body model 14 is attached to the head model 12 to form a whole body model 15. Then, as shown in FIG. 9C, a doll is obtained by attaching the costume costume 13 to the whole body model 15.

[0018]

In summary, the present invention uses a 3D camera capable of simultaneously inputting three-dimensional shape data and image data.
Since the face was photographed with the D camera, it was possible to simultaneously obtain three-dimensional shape data and image data of various facial expressions such as a smiling face, a face with a wide open mouth, and the like at the time of photographing. Although the facial model 2 and the facial photograph 3 are three-dimensional and an image, their facial expressions match, so that the facial photograph 3 can be easily transferred to the facial model 2. Further, since the prototype 5 of the face model 2 is cut by a numerically controlled machine tool based on the three-dimensional shape data obtained in the photographing process, even a complicated shape such as a face can be easily and accurately performed. Can be processed. Further, since the face model 2 is formed by the casting method using the mold 6 formed based on the prototype 5, the face shape based on the three-dimensional shape data can be faithfully restored as a three-dimensional model. The face model 2 having the same shape can be mass-produced by the mold 6. Also, the image data obtained in the photographing process is image-processed so that the outline outside of the facial image 7 that has not been photographed is modified, and the facial photograph 3 based on the image data is printed on the transfer paper 8. In the face photograph 3, a portion corresponding to the side portion 2a of the face model 2 which is not actually photographed is supplemented, and the face photograph 3 is covered on the entire surface of the face model 2.
Can be transferred. In addition, since the face photographic film 10 peeled off from the transfer paper 8 was transferred to the face model 2, various facial expressions at the time of photographing were left as they were, for example, wrinkles of the face which could not be expressed by a conventional doll. The complexion can be expressed as it is.

In the face photograph transfer step, the face photograph coating 10 made of a synthetic resin film on which the face photograph 3 is printed is peeled off from the mount 9 by immersing the transfer paper 8 in water. Since the face photograph coating 10 was stretched and attached so as to correspond to the shape, the face photograph 3 in the face photograph coating 10 was
Means that even a flat face is shown,
The image can be transferred so that each part of the face photograph 3 corresponds to the uneven shape of the eyes, nose, mouth and the like in the face model 2.

Also, the costume body 13 is attached to the decorative body W, for example, the head model 12 in which the occipital model 11 is adhered and integrated to the face model 2 to which the face photographic film 10 is transferred. By attaching the costume costume W to the whole body model 15 in which the torso model 14 is attached to the model 12, it is possible to use it as a decoration of a strap or a key holder, or to enhance the added value of the face model 2 as a doll. The effect is enormous.
