  When the methods disclosed in Patent Documents 1 and 2 are used, there is a drawback that it is difficult to perform accurate measurement without the expert knowledge and experience of the measurer, and the method disclosed in Patent Document 3 is used. Sometimes you need a three-dimensional measuring instrument. In such a conventional technique, it is difficult to provide a service for measuring the degree of lateral inclination of a customer's foot in a general shoe retail store and customizing the shoe based on the measurement result.

  The inventor has noticed the following in the process of earnestly experimenting and researching a method for easily grasping the degree of left-right inclination of a person's foot.

  That is, in the state where the person stands on the horizontal support surface with the left and right feet, the part of the buttocks of the foot that is not in close contact with the horizontal support surface when one of the feet is viewed from below If the size of the shape-dependent information obtained from the planar view shape is determined, the right / left inclination degree of the foot is uniquely specified, and if the shape-dependent information is the same, the right / left inclination degree is the same regardless of individual characteristics. Thus, it can be measured with an accuracy that does not hinder practical use.

  The present invention was created based on such facts, and the purpose of the present invention is to adjust the degree of right / left inclination of a person's foot with a necessary accuracy even if it lacks physical expertise and measurement experience. In addition, it is possible to easily obtain without using a three-dimensional measuring instrument or a protractor, and to support the customization of shoes in a retail store.

The customization support system of the present invention is a shoe customization support system comprising: display means for giving an instruction to an operator; and input means for inputting an arbitrary point coordinate in the display screen pointed to by the operator. , A scanner that irradiates light from the back side of the transmission plate to the subject that is in contact with the front side of the transmission plate, captures reflected light obtained through the transmission plate, and obtains a two-dimensional gray image, and the subject passes through the sole of the foot A means for obtaining a two-dimensional gray image of the subject's sole obtained from the scanner when contacting the board and displaying the two-dimensional gray image on the display means; and an operator is input by the input means The position input means for acquiring the position coordinates of the tip of the fingertip and the back of the heel of the subject, and the position between the position corresponding to the heel based on the position coordinates of the tip and the back of the subject The back left A reference line that crosses the reference line is displayed on the display means, and the left and right first coordinate positions at which the reference line instructed by the operator with the input means intersects the left and right acquired image outlines, and the reference line and the sole contact contour Calculates the distance between the reference point acquisition means for acquiring the left and right second coordinate positions intersecting each other and the acquired first and second acquired coordinates, and the difference between the calculated left and right distances And selection information creating means for selecting one of a plurality of predetermined discrete values and displaying the selected value on the display means.

  Further, the customization support method of the present invention irradiates a subject contacting the front side of the transmission plate of the scanner with light from the back side of the transmission plate, images reflected light obtained through the transmission plate, and the operator inputs the input The position coordinates of the tip of the subject's sole and the back of the heel input by means are specified, and the position corresponding to the heel to the heel is determined based on the position coordinates of the tip of the sole of the subject and the back of the heel. A left and right first coordinate position where the reference line intersects the right and left acquired image outlines, and a left and right second coordinate where the reference line intersects the sole contact contour. The position is specified, the distance between the first and second acquisition coordinates is calculated based on the specified left and right acquisition coordinates, and the shoe is calculated from the size obtained by dividing the right and left of the heel portion of the shoe bottom in half. Plates of different sizes up to half the size of the one split to the left and right Prepare a seed, set one or a plurality of combinations of the plurality of types of plate material with respect to the inclination of each individual foot, select one of the discrete values based on the difference between the calculated left and right distances, and selected The shoe is customized by attaching the plate material to the inner bottom of the shoe.

  According to the present invention described above, the degree of right / left inclination of the foot can be specified simply by setting the instructed input item. Therefore, even in a general retailer who lacks specialized knowledge or experience in measurement, the ready-made shoes It is possible to implement a service that provides shoes that fit the customer's feet.

  In the following description, the operator is a clerk of a retail store who receives support in the present embodiment, and the test subject is a customer of a retail store who customizes off-the-shelf shoes.

  FIG. 1 shows a shoe customization support apparatus 100 according to this embodiment. The customization support apparatus 100 includes an imaging unit 1, a computer 2, a monitor 3, a keyboard 4, and a mouse 5, and a part of the functions is realized by a software program 26 in the hard disk 24. The software program 26 is provided by being stored in a medium such as a CD or DVD readable by the computer 2 and stored in the hard disk 24.

<Imaging means 1>
The imaging means 1 images at least one foot of a person standing on the horizontal support surface with the left and right feet from below. FIG. 2 shows a specific example of the imaging means 1. A scanner 7 is housed inside the box 6 whose upper surface is opened, with the imaging surface positioned on the upper side. The scanner 7 is a flat bed type image scanner for two-dimensionally scanning an object placed on the upper glass surface, and a commercially available one for a personal computer can be used. The scanner 7 is set to the box 6 by removing the cover that covers the object when the object is placed on the glass surface. A transparent plate member such as glass or a synthetic resin material is fixedly arranged on the upper surface of the box 6 so as to cover the scanner 7. This translucent plate member is a relatively strong material so that human weight is not directly applied to the scanner 7, and provides a horizontal support surface 8 a on the upper surface of the scanner 7. For the purpose of use of the present embodiment, the depth of focus of the scanner 7 may be as long as the depth of the foot.

The scanner 7 includes an imaging device that scans the reflected light from the one leg b1 of the person to whom the lamp light is applied while moving horizontally in the front-rear direction a1, and outputs imaging information from the imaging device.
A support base 9 is provided for placing the foot b2 on the opposite side of the one foot b1, and the horizontal support surface 9a which is the upper surface thereof is a horizontal surface having the same height as the horizontal support surface 8a.
FIG. 2 shows a state in which the right foot b1 is imaged. When the left foot b2 is imaged, the positions of the box 6 and the support base 9 are reversed from each other, or the support base is also placed in the right in advance. 9 is provided so that the left foot b2 is placed on the horizontal support surface 8a.

  FIG. 3 shows an image c1 of the foot b1 in which the right foot b1 of a person standing on the horizontal support surfaces 8a and 9a with the left and right feet b1 and b2 is imaged by the imaging means 1 and displayed on the display screen 3a. Since the subject puts his / her foot on the scanner 7 as it is, the image c1 has a height at a position away from the horizontal support surface 8a to the vicinity of the heel in addition to the portion directly contacting the horizontal support surface 8a of the scanner 7. The reflected light is acquired and thinly imaged, and the image is picked up with a gray image different from the contact portion. A line surrounding the range imaged up to a position distant to the vicinity of the heel is called an outline. When observing the outline, if the subject is wearing dark socks, it will be indistinguishable from the background and must be removed. However, it is not affected when the subject wears stockings of a color close to skin color.

  In the figure, symbol c2 indicates the outline of the foot b1, symbol c3 indicates a boundary line surrounding the outer periphery of the portion in contact with the horizontal support surface 8a, and symbol c4 indicates the tip position d1 of the second finger and the buttock image. A straight line connecting the rear end position d2 is shown. When the tip position d1 is set as the tip of the fingertip on the sole and the position of the back end is set as the end position d2, the distance F1 from the tip position d1 to the end position d2 is a length corresponding to the foot length (average) The first finger is long, but depending on the subject, the second finger may be long. Symbol c5 indicates a straight line connecting the maximum separation positions of the inner and outer eyelids, symbol c6 indicates a left-right direction line passing through the rearmost end position d2 of the collar image, and symbol c7 indicates a longitudinal distance between the lines c5 and c6. The left-right direction line which passes through the substantially middle point (the approximate center position of the buttocks image in plan view) is shown. The left-right direction line c7 forms a reference line for determining the position of the point to which position information is input by the reference point acquisition means 15 described later. The reference line c7 is obtained and displayed by the reference line data means 13 described later in detail. It is displayed on the screen 3a. Note that the straight line c4, the straight line c5, and the straight line c6 are not displayed on the display screen 3a.

  In the image of the foot b1 displayed on the display screen 3a, the lamp light of the image pickup means 1 is not reflected outside the outline c2 of the foot b1 and is dark black, and the lamp light is reflected inward from the outline c2. Therefore, it becomes a relatively bright color (shading). Therefore, the operator can clearly recognize the outline c2 with the naked eye. Further, the portion within the boundary line c3 where the foot b1 is in contact with the horizontal support surface 8a (contact location) is extremely bright (dark), while the portion where the foot b1 is away from the horizontal support surface 8a (non-contact) The portion between the outline c2 and the boundary line c3, which is a location), is a relatively dark color compared to the contact location. Therefore, the operator can clearly recognize the boundary line c3 with the naked eye.

  FIG. 4 is an enlarged view of a part of the image c1 of the foot b1 in FIG. Now, the positions of the points where the reference line c7 intersects the outline c2 and the boundary line c3 are represented by the symbols e1, e2, e3, and e4 in order from the left side in FIG. 4, and the symbols e1, e2, Reference numerals e3 and e4 are referred to as reference points, and their positions are referred to as reference point positions. In addition, the distance from the position e1 to the position e2 is represented by a symbol K1, and the distance from the position e3 to the position e4 is represented by a symbol K2.

  FIG. 4 shows an image of a normal foot b1 having no right / left inclination. In this case, the distance K1 and the distance K2 are substantially the same. On the other hand, FIG. 5 is an image of the buttocks of the abnormal foot b1 displayed on the display screen 3a. FIG. 5A is an image of the buttocks of the foot b1 when the foot b1 is varus. In this case, the distance K1 is smaller than the distance K2, and FIG. 5B is a valgus of the foot b1. In this case, the distance K2 is smaller than the distance K1. Therefore, the value of the shape information becomes a size within the range of “0 to 1” regardless of whether it is varus or valgus.

<Computer 2>
As the computer 2, a normal personal computer having a CPU 21, a main memory 22, and an input / output controller 23 can be used. A program 26 executed by the CPU 21 is loaded from the hard disk 24 into the main memory 22. When the program 26 is loaded into the main memory 22, the image processing means 10, position acquisition means 11, reference point acquisition means 15, inclination degree recognition processing means 12, reference line data means 13, and member selection information described below Each routine of the creating means 14 is included. The main memory 22 holds a table 25 described later.

<Image processing means 10>
The image processing unit 10 holds information to be displayed on the display screen 3a of the monitor 3, and input instruction information to the operator, input information from the operator, and processing result information to be described later from the imaging unit 1. Even if superimposed on the image information of the foot b1 or b2 sent, it is displayed on the monitor 3. The image information to be displayed on the display screen 3a may be multicolor image information or grayscale image information such as an achromatic color.

<Position acquisition unit 11>
The position acquisition unit 11 first displays guidance on the display screen 3a so that the foot b1 is placed on the horizontal support surface 8a on the side where the scanner 7 exists. Then, guidance for sequentially inputting the front end position d1 and the last end position d2 of the buttock image is performed, and position information of an arbitrary point on the display screen 3a designated by the operator is acquired and stored in the main memory 22 It is. When guidance for position input of a point on the display screen 3 a is given to the operator, the operator displays a position input mark on the display screen 3 a at the position pointed by the mouse 5, and the operator presses the mouse 5. When the position is specified by clicking, an X mark is displayed at that position and fixed on the display screen 3a. At the same time, the position information is acquired and stored in the main memory 22 as the tip position d1 and the end position d2 of the buttock image. Remember. If there is position information to be input next, it waits for the next click of the mouse 5 together with guidance to the operator. Even if the input order is not specified by the guidance, guidance may be made so that each is individually input, and the tip position d1 of the second finger and the end position d2 of the buttock image may be input. In addition, if the user is a skilled operator without performing guidance, the sole image displayed on the screen itself serves as guidance for prompting the input of the tip position d1 and the end position d2 of the buttock image. In this case, the front end position d1 and the last end position d2 of the buttock image may be estimated from the relationship between the front and rear input positions.

<Reference point acquisition means 15>
Similar to the position acquisition unit 11, the reference point acquisition unit 15 provides guidance to the operator so that the reference point position is input in order from the left side, and position information of an arbitrary point on the display screen 3a specified by the operator. Is acquired and stored in the main memory 22. When guidance for position input of a point on the display screen 3 a is given to the operator, the operator displays a position input mark on the display screen 3 a at the position pointed by the mouse 5, and the operator presses the mouse 5. When a position is specified by clicking, an X mark is displayed at that position and fixed on the display screen 3a, and position information is acquired and stored in the main memory 22. If there is position information to be input next, it waits for the next click of the mouse 5 together with guidance to the operator. When inputting the positions of a plurality of points, the same operation is performed on each point. As a result, position information on a desired plurality of points is input and stored in the computer 2. Even if the input order is not specified by the guidance, the guidance may be performed so that the respective reference point positions are individually input, or may be estimated from the left and right positional relationship. It should be noted that it is possible to provide guidance for prompting the skilled operator to input each reference position by simply drawing a reference line, which will be described later, on the screen, without providing guidance for inputting points one by one.

<Inclination degree recognition processing means 12>
The inclination degree recognition processing means 12 recognizes the right and left inclination degrees of the measurement subject's feet based on the position information about the plurality of points input by the position acquisition means 11.

Next, the degree of left / right inclination of the foot will be described.
FIG. 6 shows the right foot b1 of a person standing on the horizontal support surface 8a with the left and right feet b1 and b2, and A is a left side view and B is a view of the buttocks as seen from the rear.

  The right / left inclination degree of the foot b1 refers to the degree of inclination of the rib f1 when the heel part is viewed from behind, for example, the heel center line g1 and the vertical line along the vertical direction of the rib f1. It is defined by the magnitude of the angle θ formed with g2. The eyelid center line g1 is a straight line connecting the lower reference point h1 and the upper reference point h2. At this time, the lower reference point h1 is at the height of the lower end of the rib f1 and is the center in the left-right direction of the rib, and the upper reference point h2 is at the height of the upper end of the rib f1 and left and right of the rib. This is the center point of the direction.

By specifying whether the heel center line g1 is displaced to the left rotation side or the right rotation side with respect to the vertical line g2, it is possible to know the degree of varus and valgus of the foot b1. In this case, as shown in FIG. 6B, the state in which the eyelid center line g1 is displaced to the left rotation side with respect to the vertical line g2 is valgus, while the eyelid center line g1 is displaced to the right rotation side with respect to the vertical line g2. The state is varus.
Therefore, the front angle θ means the angle to the left rotation side from the vertical line g2 to the heel center line g1 when viewed from the rear in the case of valgus, and in the case of varus The angle to the right rotation side from the vertical line g2 to the heel center line g1 when viewed from the rear.

Next, the correspondence data 24 will be described.
The inventors learned that the relationship between the distance K2 and the distance K1 has a close correspondence with the degree of left / right inclination of the foot. It has been found that there is a correspondence relationship in which the same result can be stably obtained for anyone between the distance K2 between the distance K2 and the distance K1 at the substantially central location and the degree of left / right inclination of the foot. The correspondence data 22 is obtained by converting this correspondence into data.

  FIG. 7 is a graph showing the correspondence between the relationship between the distance K2 and the distance K1 and the degree of left / right inclination of the foot. The horizontal axis represents the magnitude of K1 / K2 (or K2 / K1), and the vertical axis represents the magnitude of the right / left inclination of the foot. Here, in the case of varus, which will be described later, the value of “K1 / K2”, which is the ratio of the distance K1 to the distance K2, is used, and in the case of valgus, the ratio of the distance K2 to the distance K1. The value of “K2 / K1” is used.

  In this graph, the curve Q specifies the correspondence. At this time, for example, the value N1 of K1 / K2 (or K2 / K1) when the right / left inclination degree (angle θ) is 2 degrees, K1 / K2 when the right / left inclination degree (angle) is 3 degrees (or The value N2 of K2 / K1) and the value N3 of K1 / K2 (or K2 / K1) when the right / left inclination degree (angle) is 5 degrees are specified in advance.

  In this case, the correspondence data 22 indicates that when the value of K1 / K2 (or K2 / K1) is greater than or equal to N1 and less than N2, the degree of lateral inclination of the foot is small, and the special K1 / K2 (or K2) When the value of / K1) is greater than or equal to N2 and less than N3, the right / left inclination of the foot is medium, and when the value of K1 / K2 (or K2 / K1) is equal to or greater than N3, the right / left inclination of the foot Used to determine discretely that the degree is large.

<Reference line data means 13>
The reference line data means 13 specifies the distance F1 from the second finger tip position d1 and the heel rear end position d2 of the foot b1 from the position information acquired by the guidance of the position acquisition unit 11, and the reference line data is based on the distance F1. The image processing means 10 is instructed to draw the line c7 on the display screen 3a.
Assuming that the distance from the rearmost position d2 of the buttock image to the reference line c7 in the image of the foot b1 displayed on the display screen 3a is K3, the value of “K3 / F1” that is the ratio of the distance K3 to the distance F1 is It is almost the same regardless of who the foot belongs to. Therefore, the reference line data means 13 is set to “K3 / F1” as a fixed value, calculates K3 based on the specified distance F1, and displays the reference line c7.
The reference line c7 is drawn perpendicularly to the direction a1 on the assumption that the operator's foot b1 is placed almost parallel to the direction of the direction a1 (FIG. 2) with respect to the scanner 7. Is done.

  Note that the display method of the reference line c7 described above is merely an example, and for example, c7 may be drawn so as to be inclined in accordance with the inclination of the second finger tip position d1 and the heel rear end position d2.

<Member selection information creation means 14>
The member selection information creation unit 14 selects member additional information for shoes that matches the degree of right / left inclination (angle θ) of the one foot b1 from a plurality of types of additional members for shoes prepared in advance. Create
Specifically, the correspondence between a plurality of types of additional members for shoes prepared in advance, the right / left inclination degree of the foot, and the foot size is stored in advance as a table 25 in the main memory 22. To create member selection information.

  FIG. 8 shows an additional member for shoes, in which A is a perspective view and B is a cross-sectional view of X1-X1. As the additional member for shoes, four types of pads p1, p2, p3, and p4 having different forms are prepared. Each of them has a rubber-like elasticity and has a plate shape of either 2 or 3 mm in thickness, and its shape is half that of a large one that divides the inner bottom of the shoe into left and right. Yes, the small one is the size of the inner bottom of the part divided into left and right. Several types of members having different types from large members to small members are prepared. Moreover, as shown to FIG. 8B, the adhesive agent 16b is apply | coated to the upper surface and lower surface of the main body member 16a, and the release paper 16c is affixed on each of the upper and lower surfaces through the adhesive agent 16b.

  FIG. 9 shows member selection information S1, S3, S5, L2, L3, and L5 indicating the correspondence between a plurality of types of pads p1, p2, p3, and p4 prepared in advance and the degree of left / right inclination and foot length. ing. The left / right slope increases as it goes to the right in the figure, and the foot length increases as it goes down. Pads p1, p2, p3, and p4 are not prepared according to the restricted size of shoes (the total length of the foot is set in 5 mm increments), but roughly L size (large) and S size (small) It is prepared for each of two types. Here, the total length refers to the length in the direction a1 along the front-rear direction of the foot. Such member selection information is preset in the table 25.

  One or a plurality of pads p1, p2, p3, and p4 are selected depending on the number of used sheets, the thickness t, and the total length depending on the degree of right / left inclination of the foot. Specifically, it is as follows. That is, one pad p1 or p3 is used when the right / left inclination degree of the foot is small. The pad p1 or p3 has a thickness of 2 mm, the shortest total length L1 is about 10 cm, and the width B1 is about 2 cm. When the right / left inclination of the foot is medium, one pad p2 or p4 is used. The pad p2 or p4 has a thickness of 3 mm, the total length L11 is somewhat longer than L1, and the width B11 is also larger than B1 and about 3 cm. Also, when the left / right inclination degree of the foot is large, it is used when one foot p1 or p3 used when the left / right inclination degree of the foot is small and the right / left inclination degree of the foot is medium. Two sheets composed of one pad p2 or p4 are used, and when used, these two sheets are stacked to have a total thickness of 5 mm.

  As for the degree of right / left inclination of the foot, in any case of valgus or varus, the range of the angle θ where the right / left inclination is small is 2 degrees or more and less than 3 degrees, and the right / left inclination degree is medium. The range of the angle θ is 3 degrees or more and less than 5 degrees, and the range of the angle θ where the right / left inclination degree is large is 5 degrees or more.

  The member selection information creating means 14 adds the right and left slopes of the foot and the foot length calculated from the distance F1, and adds the right and left slopes and the foot length suitable for the foot length from the table 25 shown in FIG. The member selection information for selecting a member (pad) is specified.

  The member selection information is “s2” when the foot length is small and the left / right inclination angle of the foot is small, “s3” when the foot length is small and the right / left inclination angle of the foot is medium, and the foot length is “S5” when the foot is small and the left / right tilt angle is large, “L2” when the foot length is large and the foot's left / right tilt angle is small, and the foot length is large and the foot is tilted left / right. “L3” when the angle is medium, and “L5” when the foot length is large and the left / right tilt angle of the foot is large. The information selected by the member selection information creation unit 14 is transferred to the image processing unit 10 and displayed on the display screen 2a.

  Next, a shoe customization service performed at a shoe retailer will be described with reference to FIG. 10 based on the operation of the apparatus of this embodiment.

  First, in step 1 (s1), the position acquisition means 11 is executed and guidance for the operator is displayed on the monitor 2. The first guidance prompts the user to place the foot b1 on the horizontal support surface 8a on the side where the scanner 7 exists. The operator who sees this guidance instructs the subject who wishes to purchase shoes to put his / her foot on the scanner 7.

  As shown in FIG. 2, one foot b1 is placed on the horizontal support surface 8a on the side where the scanner 7 exists, the other foot b2 is placed on the other horizontal support surface 9a, and the left and right feet b1 and b2 are used. Guidance is displayed to instruct the subject to stand naturally on the horizontal support surfaces 8a and 9a. The front-rear direction of one leg b1 and the moving direction a1 of the image sensor of the scanner 7 are matched with an accuracy that can be recognized as being almost accurate visually. This guidance may be omitted if the operator is educated in advance by explaining how to use the apparatus.

  In step 2 (s2), the operator is prompted by the guidance to operate the scanner 7.

  In step 3 (s3), the image processing means 10 receives image information from the scanner 7 and displays a foot image on the display screen 3a.

  In step 4 (s4), the position acquisition means 11 displays a position input mark on the display screen 3a, and operates the mouse 5 to the operator, so that which position is two positions in the foot image. Guidance is displayed so as to specify whether it corresponds to d1 and d2. Prompted by this guidance, the operator clicks the position input display mark so as to match the positions d1 and d2 that are observed. As a result, the position acquisition unit 11 inputs position information about the two positions d1 and d2 and stores them in the main memory 22.

  In step 5 (s5), the reference line data unit 13 calculates the distance F1, and displays the reference line c7 on the display screen 3a based on the distance F1.

In step 6 (s6), the reference point acquisition means 15 displays a position input mark on the display screen 3a, and operates the mouse 5 on the operator to determine which position on the reference line c7 of the display screen 3a. Is displayed so as to designate whether the position corresponds to the four positions e1, e2, e3, e4. The operator is prompted by this guidance and clicks the position input display marks so that the positions are observed as positions e1, e2, e3, e4.
Thereby, the position acquisition means 11 inputs the position information about each position e1, e2, e3, e4 and stores it in the main recording means 22.

  Proceeding to step 7 (s7), the inclination degree recognition display output means 12 recognizes the right and left inclination degree (angle θ) of one leg b1 of the customer. At this time, if necessary, the right / left inclination degree may be displayed on the display screen 3a by characters such as an angle, large, medium, and small.

Next, the process proceeds to step 8 (s8), where the member selection information creating means 14 determines one of the customer's legs based on the distance F1 (corresponding to the foot length) on the image c1 and the right / left inclination of the foot d1. The member selection information for selecting the pads p1, p2, p3, and p4 suitable for d1 is recognized and displayed on the display screen 3a.
When the pads p1, p2, p3, and p4 for one foot b1 are specified, the procedure for the other foot b2 is performed by performing the procedure for the other foot b2 according to the case of the one foot b1. Pads p1, p2, p3, and p4 are specified.
As a result, the operator can acquire information necessary for shoe customization.

  Next, processing for adjusting a shoe using the selected pads p1, p2, p3, and p4 will be described with reference to FIGS. FIG. 11 shows a shoe adjusted with a pad, A is a side view, B is a cut end view of x2-x2 part, and FIG.

  It is assumed that a shoe that matches the size of the customer's foot is selected from ready-made shoes that are manufactured with no inclination of the foot. For this selected shoe, the pad selected in the above procedure (p1, p2, p3, p4 or one of a plurality of different types, hereinafter referred to as a specific pad) is used. As shown in FIG. 11, the specific pad is fixed to the left and right sides of the heel support surface portion of the inner bottom surface m1 at a location between the inner bottom surface m1 of the shoe and the shoe insole n1.

  For this fixing, for example, the insole n1 for shoes is partially peeled from the inner bottom surface m1 of the shoe, and in this state, the specific pad in the state where the release paper 16c is peeled off is left and right of the heel support surface portion of the inner bottom surface m1 Then, the insole n1 for shoes is displaced so as to return to the original position, and is pressed and adhered to the upper surface of the specific pad. When using two pads, the small pad is placed down and the large pad is placed over the entire surface of the small pad. At this time, it is more difficult for the subject to feel a step when the large pad runs from the small pad toward the center line of the shoe.

  When it is desired to adjust the shoe to a comfortable state, processing is performed so that the sole and the upper surface of the shoe insole n1 become familiar. For this reason, when it is determined that the foot is varus from the left-right inclination of the foot, the specific pad is illustrated in the case of the right foot shoe w shown in FIG. It is fixed within the middle left half range r1. On the other hand, if it is determined that the foot is valgus contrary to the above, the specific pad is turned upside down, and it is shown in the case of the right foot shoe shown in FIG. It is fixed within the middle right half range r2.

  Furthermore, when the right / left inclination degree of the foot is small, one pad p1 or p3 is fixed, and when the inclination degree is medium, one pad p2 or p4 is fixed, and the inclination degree is If it is large, for example, as shown in FIG. 12A, one pad p1 or p3 and one pad p2 or p4 are fixed in a stacked manner.

The above embodiment can be modified as follows.
(1) The reference line c7 may be obtained from the straight lines c5 and c6 by recognizing the straight lines c5 and c6 in FIG.

(2) The values N1, N2, and N3 shown in FIG. 7 and the ranges of the large, medium, and small divisions indicating the degree of the angle θ of the right and left leg and the number of divisions may be arbitrarily changed. .

(3) It is also possible to artificially specify the pads p1, p2, p3, and p4 corresponding to the degree of left / right inclination of the foot from the degree of right / left inclination of the foot by using a printed matter showing the correspondence shown in FIG. There is no problem.

(4) The image processing means 10, the position acquisition means 11, the reference point acquisition means 15, the inclination degree recognition processing means 12, the reference line data means 13, and the member selection information creation means 14 realized by the program 26 are replaced with a firm, wired It may be realized by hardware such as logic.
