  In recent years, there has been an increasing demand for medical wigs required for the use of anticancer agents and hair loss due to chemotherapy, alopecia areata, head scars and hair loss due to burns.

JP 2011-157636 A JP 2011-195975 A

  However, particularly in medical wigs, there is a strong desire to prevent the use of wigs from being noticed by surrounding people, and wigs that reproduce the same hair as before the start of treatment are required. For this reason, there are many requests for tailor-made products that fit exactly to you, not ready-made wigs. When producing a complete custom-made wig, the manufacturing period is long (about one and a half months). For this reason, the user's desire to obtain a wig as soon as possible has not been fully met. Specifically, if the hairdressing salon where the wrap model, which is the original base modeled from the head, is located far away from the production area of the wig (such as when the wig production area is overseas), only the transportation of the wrap model But it took about 1-2 weeks. Moreover, when the wrap model is transported, the wrap model may be deformed, damaged, or lost.

  Furthermore, when producing a custom-made attachment to be worn on a part of a human body, not limited to a wig, it has been desired to solve the same problem.

  Therefore, an object of the present invention is to provide a method for producing a custom-made attachment that enables faster production than before when an order is received.

  A first aspect of the present invention is a method for producing a custom-made attachment to be worn on a part of a human body, wherein three-dimensional shape data corresponding to the part of the human body is transmitted to a production place, and the production is performed. A mold that is a model imitating a part of the human body on the ground, and a mold suitable for the three-dimensional shape data is prepared, and the attachment is produced according to the mold. It is a method to do.

  A second aspect of the present invention is a method for producing a custom-made attachment according to the first aspect, storing the transmitted / received three-dimensional shape data and storing the transmitted / received three-dimensional shape data in the past. It is determined whether or not it is approximate to the three-dimensional shape data, and when it is determined that the three-dimensional shape data stored in the past is approximate, a mold corresponding to the approximate three-dimensional shape data is determined. It is used to produce the attachment.

  A third aspect of the present invention is a method for producing a custom-made attachment according to the second aspect, which is an area on the transmitted / received three-dimensional shape data and a comparison defined on the three-dimensional shape data. The perimeter of an area consisting of a portion that is less than or equal to a predetermined distance from the reference point, and the area on the three-dimensional shape data stored in the past, the portion that is less than or equal to the predetermined distance from the point corresponding to the comparison reference point By comparing with the peripheral length of the region, it is determined whether or not the transmitted and received 3D shape data approximates the previously stored 3D shape data.

A fourth aspect of the present invention is a method for producing a custom-made attachment according to the second or third aspect, wherein the transmitted and received three-dimensional shape data approximates the previously stored three-dimensional shape data. If it is determined that the received three-dimensional shape data is not generated, two-dimensional development data obtained by dividing the received three-dimensional shape data along the dividing line is output as a development diagram, and the three-dimensional shape of the three-dimensional shape data is output from the development diagram. The mold is prepared based on the restored three-dimensional shape.
According to a fifth aspect of the present invention, there is provided a method for producing a custom-made attachment according to any one of the first to fourth aspects, wherein the three-dimensional shape data is a two-dimensional attribute of the attachment. It includes two-dimensional data to be expressed, and is produced by reflecting the two-dimensional data on the attachment.

  According to a sixth aspect of the present invention, there is provided a support system for supporting the production of a custom-made three-dimensional shape, a communication means for transmitting or receiving three-dimensional shape data, and storing the three-dimensional shape data. And a determination unit that determines whether or not the three-dimensional shape data is approximate to the three-dimensional shape data stored in the storage unit.

A seventh aspect of the present invention is the support system according to the sixth aspect, wherein the three-dimensional shape object is a custom-made attachment object to be worn on a part of a human body, and the three-dimensional shape data is: A three-dimensional shape data of a mold produced based on a part of the human body or a part of the human body, wherein the determination means converts the three-dimensional shape data into the three-dimensional shape data stored in the storage means. The apparatus further includes a selection unit that selects a model that is a part of the human body and that corresponds to the approximated three-dimensional shape data when it is determined to be approximate.
An eighth aspect of the present invention is the support system according to the sixth or seventh aspect, wherein the three-dimensional shape data includes two-dimensional data representing an attribute relating to a surface of the wearing object. Reproduction support means for assisting reproduction of the dimension data on the attachment is further provided.

  According to a ninth aspect of the present invention, a communication means for transmitting or receiving three-dimensional shape data, a storage means for storing the three-dimensional shape data, and the three-dimensional shape data are stored in the storage means. A determination means for determining whether or not the three-dimensional shape data is approximated, and a three-dimensional shape data approximated by the determination means. A program for functioning as a production support apparatus, comprising selection means for selecting a mold corresponding to the approximate three-dimensional shape data.

  A tenth aspect of the present invention is a computer-readable recording medium on which the program according to claim 9 is recorded.

  When outputting the developed view, m lines (m is a natural number of 1 or more) are given as the dividing lines so as to pass through a reference point which is a point on the surface of the three-dimensional shape data, and in the production step, In the vicinity of the reference point, the wig base may be produced while the developed views are connected together. Thereby, the developed view is connected at least near the reference point. Therefore, it becomes easy for the operator to accurately restore the three-dimensional shape from the developed view.

  Further, when outputting the development view, a marker is given to the three-dimensional shape data so as to intersect the dividing line, and the three-dimensional shape data is developed so that the marker is divided, In the output step, the marker divided together with the development view may be output. Thereby, it becomes possible for the operator to paste the dividing lines by using the markers. Therefore, it becomes easier to accurately restore the three-dimensional shape.

  After restoring the original three-dimensional shape, the accuracy of the three-dimensional shape may be confirmed. At this time, the accuracy of the three-dimensional shape is confirmed by comparing the length of the dividing line with the length of the bonding line corresponding to the dividing line and the actually measured length in the three-dimensional shape. It may be. As a result, the accuracy of the restored three-dimensional shape of the wig base can be confirmed using an objective criterion such as the length of the dividing line and the bond line. Furthermore, when confirming, the length of the said adhesion line may be divided and measured, and the sum total of the measurement result of the said several part may be made into the length of the said adhesion line. As a result, it becomes easy to approximately measure the length of the wig base bonding line that is rounded and uneven and confirm the accuracy of the three-dimensional shape.

  As a method for acquiring three-dimensional shape data from a molded lap model, a three-dimensional information measuring method or the like invented so far by one of the inventors of the present application can be used (for example, Japanese Patent No. 4883517 (Registered on Dec. 16, 1993), Japanese Patent No. 4986679 (Registered on 24.5.11 Flat), Japanese Patent No. 4590592 (Registered on 22.9.24 Flat), Japanese Patent Laid-Open No. 2010-185820, Japanese Patent Laid-Open No. 2011-64617, (See Kai 2011-179982).

  According to each aspect of the present invention, when the production site is a remote site as viewed from the user, it is possible to produce an attachment faster than before. For example, it is possible to instantaneously transmit the three-dimensional shape data of the head to a wig production place at a remote place, and to produce a wig base having a shape similar to a lap model in the wig production place. Therefore, it is possible to prepare a mold used for wig production earlier than before in the wig production area without deforming / damaging / losing the lap model.

  Further, according to the second aspect, by storing several tens to several hundreds of databases, it is possible to confirm by a fitting method whether the three-dimensional shape of the user's head is approximate to the past user. In the case of approximation, it is possible to immediately start wig production at the wig production place and to produce the wig more quickly. Other wearing items have the same merit.

  In addition, wigs can be produced quickly in response to repeater orders. For example, a wig is a consumable that has a life span of about 2 to 3 years. There is also a need to own a spare. Therefore, when the wig is produced again, it is not necessary to mold again from the user's head by reusing the three-dimensional shape data. In addition, the three-dimensional shape data is free from the risk of damage or deterioration over time. The same applies to other attachments.

  Furthermore, according to the 3rd viewpoint, it becomes easy to perform exact fitting using the reference | standard suitable for production of an attachment with objective.

  Furthermore, according to the 4th viewpoint of this invention, even if it determines with there being no data approximated by fitting, it becomes easy to prepare a mold. Here, in order to accurately restore the three-dimensional shape data, a three-dimensional printer can be used in the wig production area. However, since the three-dimensional printer and its running cost are very expensive, the cost of the wig is increased. According to the present invention, it is easy to accurately restore a three-dimensional shape through a two-dimensional development view, so that the three-dimensional shape can be restored at low cost. In particular, it can be said that the lap model shape that does not have a typical three-dimensional shape (for example, a hemispherical surface) can be generally restored from the developed view.

It is a block diagram which shows the outline | summary of the assistance system which concerns on a present Example. It is a figure which shows an example of the setting of angle | corner (alpha) and angle | corner (beta), Comprising: (a) What showed the semicircle-shaped figure 41 for simplicity as an example of a wig base, (b) An example of a two-dimensional development view FIG. It is a figure which shows an example of the reference | standard used for a fitting method.

  First, the current situation where conventional custom-made wigs take time will be described. Custom-made wigs take longer to make than ready-made products with uniform specifications. The cause is the production process.

  In the current production process for custom-made wigs, first, the shape and hair flow are examined, and the wig shape, dimensions, hair implantation method, etc. are recorded by hand according to the user's wishes. create. The material of the wrap model is a food packaging film (a vinyl-like film made of polyvinylidene chloride is acceptable. For example, a wrap film covering the head in the case of hair coloring for a beauty salon is also acceptable). Next, the lap model is transported to the production plant. Wig production is often performed at overseas factories to reduce costs. At the production plant, a mold (head mold) is made from foam model with foamed urethane or gypsum from the wrap model, and the wig base fabric (or polyurethane, silicone, etc.) is applied to the mold, and then transplanted by hand onto the wig base fabric. Do. Wigs made at overseas production plants are transported to wig manufacturers in Japan. After that, the staff cuts the hair of the wig and provides it to the user at the beauty salon, which is a partner store.

  In this way, since it is often produced in remote places such as overseas, it takes time and cost to transport the lap model. Moreover, many wrap models are made of soft materials, and there is a risk of deformation, contamination, damage or loss during transportation.

  Accordingly, embodiments of the present invention will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following examples.

  FIG. 1 is a diagram showing an outline of the steps of a wig production method according to an embodiment of the present invention (an example of “a method for producing a custom-made attachment” in the claims of the present application).

  In step ST001, a beauty model or the like creates a wrap model 1 reflecting dimensions and hair flow from the user's head (an example of “part of the human body” in the claims of the present application). In step ST002, using the three-dimensional image measurement system 3 having a three-dimensional measurement unit and a two-dimensional measurement unit, which was developed by one of the inventors, the three-dimensional shape, dimensions, and hair of the wrap model 1 Combined with two-dimensional design information (an example of “two-dimensional data” in the claims of the present application) written on the surface of the lap model 1, and the combined 3D model data 5 (“three-dimensional shape data in the claims of the present application”). As an example). In step ST003, the comprehensive 3D model data 5 is stored in the server 7. In step ST004, the comprehensive 3D model data 5 is transmitted to the computer 13 in the production area 11 of the wig from the sales office 9 near the user's location. In step ST005, the received comprehensive 3D model data 5 is divided into two-dimensional development diagram data (an example of “two-dimensional development diagram data” in the claims of the present application), and an output device (not shown) outputs it as a two-dimensional development diagram 15. Subsequently, in step ST006, the three-dimensional wig base 17 is restored from the two-dimensional development drawing 15. Subsequently, in step ST007, it is confirmed whether or not the wig base 17 has been correctly restored. If correctly restored, in step ST008, a mold 19 (an example of “mold” in the claims of the present application) is manufactured based on the wig base 17. Furthermore, in step ST009, the wig 20 (an example of “attachment” in the claims of the present application) is manufactured in accordance with the mold 19, and in step ST010, the wig 20 is delivered to the user. If it is determined in step ST007 that the data has not been correctly restored, the process returns to ST005, and the two-dimensional development view 15 is output again to restore the wig base 17. Here, the two-dimensional design information is reproduced on the wig base 17. The computer 13 and the output device are an example of “reproduction support means” in the claims of the present application.

  In the above, the three-dimensional image measurement system 3, the server 7, the computer 13, and the output device as a whole support a system for restoring a three-dimensional shape at a remote place (an example of “support system” in the claims of the present application). ).

  In the above-mentioned step ST004, since the comprehensive 3D model data 5 is transmitted to the remote production area 11, time for transporting the lap model 1 is not required. Moreover, there is no possibility that the lap model 1 is deformed, contaminated, damaged or lost during transportation.

  In step ST005, the wig base 17 can be restored with a normal printer because it is output as a two-dimensional development drawing 15. Therefore, compared with the case where it restores using a three-dimensional printer, expense can be suppressed significantly.

  Here, in order to restore the wig base 17 from the three-dimensional shape data 5 through the two-dimensional development drawing 15, it is necessary to generate an accurate two-dimensional development drawing 15. Hereinafter, the configuration of the support system will be described with reference to FIG.

  FIG. 2 is a block diagram illustrating an overview of the support system 21 according to the present embodiment. The support system 21 includes a development support unit 22, a fitting support unit 24, a two-dimensional design information reproduction support unit 40 (an example of “reproduction support means” in the claims of the present application), and a storage unit 26 (“memory” in the claims of the present application). And an example of “communication means” in the claims of the present application. The development support unit 22 includes a parting line provision unit 23, a development unit 25, a parting line length acquisition unit 27, and a parting line length display unit 29. The fitting support unit 24 includes a comparison reference point determination unit 30, a region determination unit 32, a perimeter determination unit 34, a comparison unit 36, and a determination unit 38. The storage unit 26 includes a 3D shape storage unit 31 and a parting line length storage unit 33. The dividing line giving unit 23 puts 12 dividing lines (an example of “dividing line” in the claims of the present application) into the overall 3D model data 5. The expansion unit 25 divides the overall 3D model data 5 along the dividing line and expands the data into two-dimensional development drawing data. The dividing line acquisition unit 27 acquires the length of the dividing line. The 3D shape storage unit 31 stores the comprehensive 3D model data 5 created by the 3D image measurement system 3. The dividing line length storage unit 33 stores the length of the dividing line. The dividing line display unit 29 displays the length of the dividing line. The communication unit 28 transmits and receives the comprehensive 3D model data 5. The fitting support unit 24 will be described later. The 2D design information reproduction support unit 40 displays the 2D design information on the wig base 17 so that the 2D design information is reflected in the produced wig.

  In step ST007 of FIG. 1, a criterion for determining the accuracy of restoration of the wig base 17 is required. Therefore, the length of the dividing line displayed by the dividing line length display unit 29 and an adhesive line obtained by actually measuring the trace corresponding to the dividing line connected when the wig base 17 is restored (an example of “adhesive line” in the claims of the present application) Compare the length. By using the index of the length of the dividing line (the length of the bonding line), it is possible to objectively determine the accuracy of restoration of the wig base 17. Moreover, since the dividing line (adhesion line) is directly related to the conversion of 3D → 2D → 3D, the length of the dividing line (adhesion line length) is a particularly preferable index.

  Next, in describing how to determine a dividing line, the dividing line provision unit 23 will be further described. The dividing line provision unit 23 includes a reference point determination unit 35, a reference point neighborhood determination unit 37, and a marker provision unit 39.

  The reference point determination unit 35 determines a reference point that is a point on the surface of the comprehensive 3D model data 5. First, the 3D model is cut so that it is divided into right and left at a line where the plane perpendicular to the straight line connecting both ears and the 3D model data 5 intersects, and a curve where the cut surface and the surface of the model intersect is plotted in the 3D model data 5 The center line shall be the reference point at the top of the center line. Here, the top means the highest point when the wig base is put on the mold. Then, the dividing lines are set so that the twelve dividing lines pass through the reference point. The reference point vicinity determination unit 37 determines a region that is in the vicinity of the reference point and that does not have a dividing line. The marker assigning unit 39 assigns a marker that intersects the dividing line to the comprehensive 3D model data 5.

The dividing line providing unit 23 sets the intersecting line between the 12 planes passing through the axis passing through the reference point of the comprehensive 3D model data 5 and the surface of the integrated 3D model data 5 as a dividing line. Angles between 12 planes and adjacent planes are α ₁ , α ₂ ,..., Α ₁₂ (hereinafter collectively referred to as α _i ).

  Here, for accurate comparison, it is necessary to measure the length of the bonding line as accurately as possible. However, the bond line on the wig base 17 simulating the head may be a curved curve. Therefore, a plurality of intermediate points are set from the reference point for each angle β formed by the reference point and one point on the axis passing through the reference point and the intermediate point on the bond line. FIG. 3 is a diagram illustrating an example of setting the angle α and the angle β. FIG. 3A shows a hemispherical figure 41 as an example of a wig base for the sake of simplicity, and FIG. 3B shows an example of a two-dimensional development view.

In FIG. 3A, the reference point S, the Z axis as the axis passing through the reference point S, the dividing line D _{1 having} a length l ₁ passing through the reference point, the dividing line D _{2 having} a length l ₂ passing through the reference point, and the dividing line _{L 1} from the reference point S of the line _{D 2} to an intermediate point _{M 1,} showing the angular alpha ₁ and angular beta _1. FIG. 3B shows the length of the dividing line in the two-dimensional development view.

For example, suppose that β is 5 °, and intermediate point 1, intermediate point 2,... Intermediate point 18 is set from the reference point. At this time, the length from the reference point to the intermediate point 1, the length from the intermediate point 1 to the intermediate point 2,... The length of the line. The accuracy of the lap model wig base 17 is confirmed by comparing the actually measured length of the bond line with the length l ₂ on the data displayed by the dividing line length display unit 29.

  By dividing and measuring the bond line in this way, the length of the bond line can be measured as accurately as possible even if the lap model is an irregular curved surface and the bond line is a complicated curve. . In FIG. 3A, the line segment from the reference point to the intermediate point 1 is indicated by a bold line.

  The reference point vicinity determination unit 37 determines a region 43 that is a region near the reference point and that is not divided. As a result, the wig base can be restored while the two-dimensional development views are integrally connected in the vicinity of the reference point. Therefore, in step ST006, it becomes easier for the operator to accurately restore the three-dimensional shape from the two-dimensional development view as compared with the case where the wig base is restored from the 12-part separated parts of the two-dimensional development drawing. .

  The region 43 in the vicinity of the reference point may be determined based on the balance between the accuracy of the wig base to be restored and the ease of work by the operator. In this embodiment, as shown in FIG. 3B, a circle with a radius of 1 mm centered on the reference point is used.

  The marker imparting unit 39 imparts to the overall 3D model data 5 an ellipse marker 45 that goes around the axis passing through the reference point through the wig base as a marker that intersects the dividing line. The presence of this marker allows the operator to paste the dividing lines using the marker. Therefore, it becomes easier to accurately restore the three-dimensional shape.

  Here, in the flow of FIG. 1, a development view is output from the comprehensive 3D model data received at the production site, and the mold 19 is manufactured based on the wig base restored from the development view. Instead, dozens to hundreds of databases are stored in a memory (an example of “storage means” in the claims of the present application), and the three-dimensional shape of the user's head is approximate to the past three-dimensional shape data of the user The determination may be made by a fitting method. In the case of approximation, it is possible to produce a wig more quickly by selecting a mold already produced in the wig production area and immediately starting production of the wig using the mold. In this case, it may not be as accurate as the wrap model 17, but a wig may be produced together with a base in which the two-dimensional design information is two-dimensionally expressed, or the two-dimensional design information may be directly written in the mold. However, when it is assumed that the mold is repeatedly used for fitting, it is desirable to separately create a base expressing two-dimensional design information separately from the mold. The base production apparatus for producing such a base is another example of the “reproduction support means” in the claims of the present application.

  The fitting will be specifically described with reference to FIGS. FIG. 4 is a diagram illustrating an example of a reference used for the fitting technique. First, the comparison reference point determination unit 30 determines a comparison reference point that is a point on the surface of the comprehensive 3D model data 5. Here, it cuts so that it may divide into right and left by the line | wire which the surface perpendicular | vertical to the straight line which connects both ears, and the synthetic | combination 3D model data 5 cross | intersect, and the curve which the cut surface and the model surface cross | intersect A center line is set, and the top of the center line is set as a comparison reference point A. In addition, a point 10 cm below the center line from the point A is set as a comparison reference point B. Further, a point 10 cm lower than the point A along the line connecting both ears through the point A is set as a comparison reference point C. Points A, B, and C are examples of “comparison reference points” in the claims of the present application.

Subsequently, the region determination unit 32 determines a region S _A1 that is a region on the comprehensive 3D model data 5 and includes a portion not more than a distance of 5 cm from the point A. In addition, regions S _A2 and S _A3 are defined which are portions of a distance of 7 cm or 9 cm or less from the point A. Furthermore, the regions S _{B1 to} S _B3 and S _{C1 to} S _C3 including the portions of the distances of 5 cm, 7 cm, and 9 cm around the points B and C are also determined in the same manner. Since the overall 3D model data 5 has irregularities, these regions are not necessarily circular and depend on the three-dimensional shape of the overall 3D model data 5. Furthermore, the perimeter determination unit 34 determines the perimeter of these areas (perimeter: an example of “perimeter” in the claims). These perimeters are used as a criterion for fitting. S _{A1 to} S _A3 , S _{B1 to} S _B3, and S _{C1 to} S _C3 are examples of “regions” in the claims of the present application. Further, data regarding the comparison reference point, the region, and the perimeter is stored in the 3D shape storage unit 31.

  The comparison unit 36 compares the perimeter acquired from the received three-dimensional shape data with the perimeter of the three-dimensional shape data stored in the past by the 3D shape storage unit 31. The determination unit 38 determines whether or not the transmitted and received 3D shape data approximates the previously stored 3D shape data based on the comparison result.

  If it is determined in step ST007 that the data has not been correctly restored, the process may return to step ST006 without passing through step ST005. For example, the restored wig base 17 may be disassembled and the wig base 17 may be restored correctly again.

  Further, the 3D shape storage unit 31 may store only three-dimensional shape data to which information such as how the hair flows is not attached, instead of the comprehensive 3D model data. Or you may memorize | store both comprehensive 3D model data and three-dimensional shape data. Similarly, the parting line provision unit 23, the development unit 25, the parting line length acquisition unit 27, or the parting line length display unit 29 may process three-dimensional shape data.

  Further, the support system 21 may be in a business office 9 near the user location or in the production area 11. In the former case, the comprehensive 3D model data 5 to which the dividing line is assigned may be transmitted to the production area 11 or may be expanded into two-dimensional development map data and transmitted to the production area. However, it is preferable that the comprehensive 3D model data 5 can be confirmed in the production area 11.

  Furthermore, as a reference for determining the accuracy of restoration of the wig base 17, another index of the length of the dividing line (the length of the bonding line) may be used. For example, an indicator such as the circumference of the wig base may be used.

  Further, the number of dividing lines provided by the dividing line providing unit 23 may be m (m is a natural number of 1 or more) other than 12, such as 8, 24, and the like. However, if there are too few dividing lines, the restored lap model 17 may not be accurate. Moreover, when there are too many dividing lines, there is a risk that the work of restoration will be complicated. Therefore, the number is 12 in the above embodiment.

Furthermore, the angles α _i need not be equal to each other. For example, in order to accurately restore the lap model, the angle may be set small or large according to the size of the partial curvature of the wig base. Further, each angle of α _i may be determined based on a standard other than the curvature of the lap model.

Further, the angle β may be an angle other than 5 °. Further, for example, β ₁ , β ₂ ,... Β ₁₈ (hereinafter collectively referred to as β _i ) may have different angles of β _i .

  Furthermore, the marker providing unit 39 may provide a marker other than an ellipse as long as the marker intersects the dividing line. For example, a character, a figure, a symbol, etc. may be sufficient.

  Furthermore, the dividing line length acquisition unit may be any unit that acquires the dividing line length on the data, and may be obtained by electronic calculation or may be acquired by an external input. .

  Further, the dividing line length display unit may directly display the dividing line length acquired by the dividing line length acquisition unit 27 or may display the dividing line length once stored in the dividing line length storage unit 33. . The dividing line length display unit 29 may electronically display the dividing line length on the display of the computer 13 or the like, or may display the dividing line length by printing. For example, it may be output together with the output two-dimensional development drawing 15.

  Furthermore, as a reference point determined by the reference point determination unit 35, a point farthest from a straight line passing through both ends of the center line may be used as a reference point, or a point corresponding to the location of the toothpick may be used as a reference point.

  Further, the mold may be a mold for producing a three-dimensional attachment other than a wig. For example, it may be a mold for producing clothes, rings, contact lenses, artificial hands, artificial legs, artificial joints, pillows, golf club grips, bats and the like. In this case, the original base and the comprehensive 3D model data are also related to the three-dimensional shape of the body corresponding to the clothes.

  Further, the comparison reference point is not necessarily the same as the reference point determined by the reference point determination unit 35. Further, there may be one or more comparison reference points. In general, it is preferable to prepare a plurality of comparison reference points because accurate fitting is possible. Moreover, what is necessary is just to determine suitably how to determine the fitting reference | standard based on a comparison reference point. However, the peripheral length and area of the predetermined region also serve as an index as to whether or not the product to be produced can be worn, and is preferable as a fitting reference.
