The present invention relates to a data providing device, a foot care product providing method, and a foot care product.

For patients with foot lesions accompanied by foot deformities, commercial shoes do not fit well and the burden on the feet is heavy, so custom-made special shoes and insoles were necessary. However, custom-made shoes are inconvenient because they require many visits to hospitals and shops for diagnosis by a doctor, measurement of foot size by a prosthetist, adjustment of shoes, and the like.

Therefore, in order to facilitate custom-made shoes, a system has been proposed in which a user's foot is photographed, the dimensions of the foot are measured from the photographed image, and a 3D model of the shoe is formed (for example, patent Reference 1).

The manufacturing device 32 forms the foot care product 5 or parts thereof based on the design data. After the foot care product 5 is manufactured by assembling the parts, the reception terminal 31 performs delivery processing of the foot care product 5 .

(Providing foot care products)
FIG. 3 shows the processing flow of the foot care product providing system 100 when providing the foot care product 5. As shown in FIG.
In the foot care product providing system 100, first, the user terminal 1 generates measurement data of the three-dimensional shape of the user's foot (step S1). The measurement data refers to data obtained by measuring the three-dimensional shape of the foot or data used for calculation for measurement.

The user terminal 1 can transmit the image data of the foot taken by the camera to the data providing device 2 as measurement data. The data providing device 2 can analyze the image data and calculate the three-dimensional shape of the foot. The measurement data is not limited to photographed image data, and may be data obtained by calculating a three-dimensional shape such as the length, width, or instep height of the user terminal 1 from the image data. Data that has already been measured in and input by the user may be used.

FIG. 4 is a diagram for explaining a method of measuring feet.
The feet are photographed from multiple directions. When photographing the foot, it is preferable that the auxiliary tool for measurement is photographed together with the foot. As auxiliary tools, a sheet 11 on which a grid is printed, a sticker-like marker 12 to be attached to the leg, or the like can be used. The three-dimensional size of the foot can be easily calculated based on the position, size, or degree of deformation of the shape of the grid or marker 12 . It is preferable that the seat 11 is arranged so as to surround not only the floor surface but also the three sides of the foot, because it facilitates three-dimensional measurement of the foot size.

The user terminal 1 generates order data for the foot care products 5 and transmits it to the data providing device 2 together with the measurement data (step S2). The order data includes orderer information such as the name and address of the user who placed the order, product information data such as the type of foot care product 5 to be purchased (insole, pad or sock), color or price.

The processing of the user terminal 1 may be performed by an application installed on the user terminal 1. According to guidance from the application, the user can perform input operations such as the photographing and orderer information. Alternatively, the user terminal 1 may access a website from which the foot care product 5 can be ordered, and follow the instructions on the website to upload photographed data, orderer information, etc. to the website. Both the application and website are provided by the data providing device 2 .

In the data providing device 2, the control unit 211 receives the order data transmitted from the user terminal 1 and instructs the calculation processing unit 212 to design. The calculation processing unit 212 calculates the design data of the foot care product 5 based on the measurement data transmitted together with the order data in accordance with the instruction from the control unit 211 (step S3). Calculation of design data will be described later.

Furthermore, the control unit 211 generates order data from the order data and causes the communication unit 23 to transmit it to the manufacturing system 3 together with the calculated design data (step S4). The order data includes data such as product information of the foot care product 5 to be manufactured, orderer information of the user who delivers the foot care product 5, and the like.

In the manufacturing system 3 , when the reception terminal 31 receives the order data transmitted from the data providing device 2 , the reception terminal 31 transmits the design data transmitted together with the order data to the manufacturing device 32 . The manufacturing device 32 manufactures the foot care product 5 based on the design data (step S5).

When the foot care product 5 is an insole or pad, the design data specifies the type of resin. The manufacturing device 32 can manufacture the insole or pad by 3D printing using the designated type of resin. The manufacturing device 32 also arranges the sensor 6 on the foot care product 5 based on the design data. Thereby, the sensor 6 is arranged at a position based on the three-dimensional size of the user's foot.

The reception terminal 31 executes delivery processing based on the order data (step S6). For example, in the delivery process, the reception terminal 31 prints a delivery destination list, an invoice of the delivery destination, and the like, and transmits delivery request data to the computer of the delivery company.

FIG. 5 shows the processing of the data providing device 2 when calculating design data.
In the data providing device 2, the calculation processing unit 212 first calculates the three-dimensional size of the user's foot from the measurement data (step S31).

For example, if the measurement data is image data obtained by photographing a foot, the calculation processing unit 212 analyzes a plurality of image data to detect edges of the surface of the foot, and calculates the length, width, and height of the foot at a plurality of positions. Calculate in When the sheet 11 with the grid or the marker 12 is included in the photographed image, the calculation processing unit 212 detects the grid and the marker 12 in the sheet 11 . The calculation processing unit 212 can also calculate the length, width and height of the foot from the distances between the vertices of the grid, or calculate the position of the surface of the foot by measuring the distance from the floor to the marker 12. can also

The calculation processing unit 212 prepares a database in advance of the distance from the camera to the grid or marker 12, the amount of deformation of the grid or marker 12 when changing the angle of the surface of the foot, or the amount of change in size. can also In this case, by matching the amount of deformation or the amount of change in size of the grid of the sheet 11 or of the marker 12 detected from the image data with the database, the distance from the camera to the grid or the marker 12, the surface of the foot, Tilt angles, distances between markers 12, etc. can be calculated.

Further, the calculation processing unit 212 may calculate the feature amount from each image data and detect the position of the feature point having the common feature amount. For example, a three-dimensional model of the foot can be formed by arranging detected feature points in a three-dimensional space using feature points such as the toes, heels, and ankles of the feet as reference points.
Any known calculation method can be used as long as the size of the three-dimensional shape can be calculated without being limited to the calculation method described above.

Next, the calculation processing unit 212 calculates the material, thickness, shape, size, etc. of the sock part, which is a fabric product among the foot care products 5, based on the calculation result of the foot size (step 32). This process is omitted when the foot care product 5 is only a resin product such as an insole or a pad.

The calculation processing unit 212 can compare the user's foot size with the standard foot size, and determine the material, thickness, shape, size, etc. of the parts of the sock according to the difference. For example, when the width of the foot is larger than the standard size by a certain value or more, the calculation processing unit 212 divides the sock into three parts: a part that covers the sole, a part that covers the right side of the foot, and a part that covers the left side of the foot. can do.

It is better for the sock to have high elasticity, as the areas with more unevenness than the standard size are more likely to rub against the shoes and receive impact when walking. The elasticity of the sock can be enhanced by choosing a thick material fabric or choosing a highly cushioned knitting method such as pile knitting. Normally, the material and weaving method of all parts are the same, but if, for example, the width of the foot and the height of the instep at the big toe are larger than the standard size by more than a certain amount, the elasticity of the part covering the big toe will be increased by one level. , the computational processing unit 212 can determine the thickness, material, or knitting of the part.

Further, the calculation processing unit 212 calculates the elasticity, material, thickness, shape, size, or arrangement position of the insoles, pads, sandals, etc., which are resin products among the foot care products 5, based on the calculation result of the foot size. etc. are calculated (step S33). Specifically, the calculation processing unit 212 can compare the user's foot size with a standard shoe size or a standard foot size, and determine the elasticity or the like according to the difference.

6A and 6B show an example of a user's foot size and standard shoe and foot sizes. 6A is a side view and FIG. 6B is a top view.
The calculation processing unit 212 reads out the standard size shoe model K2 and the standard size foot model K3 from the storage unit 22 and arranges them in the three-dimensional virtual space. Each model K2 and K3 is generated in advance based on a statistically average size for each foot length and stored in the storage unit 22 .

The shoe model K2 is a three-dimensional virtual model that reproduces the three-dimensional shape of the inner surface of the shoe. A standard size foot model (hereinafter referred to as a standard model) K3 is a three-dimensional virtual model that reproduces the three-dimensional shape of a standard foot. Three points P1 to P3 for supporting the foot during walking are set at the big toe, little toe and heel of the standard foot model K3. Also, an arch A connecting points P1 to P3 is set.

Next, the calculation processing unit 212 generates a three-dimensional model K1 that reproduces the three-dimensional shape of the surface of the user's foot from the measurement result of the user's foot size. The calculation processing unit 212 arranges the foot model K1 inside the shoe model K2 in the virtual space, and adjusts the position so that the end in the front-rear direction y matches the standard foot model K3.

The calculation processing unit 212 matches the foot model K1 with the standard model K3 to determine points P1 to P3 in the foot model K1. For example, the calculation processing unit 212 projectively transforms the points P1 to P3 and the arch A set in the standard model K3 to the model K1.

The calculation processing unit 212 determines the size and thickness of the insole 51 to be placed in the shoe model K2 so that the weight is supported at the three points P1 to P3 and the curvature of the arch A is maintained. do. For example, the base insole 51 is determined to have a size and shape that is smaller than the area of the sole and larger than the area of the foot, and the thickness is determined so as to fit the toes and heels. In addition, the thickness is adjusted so that the upper surface of the foot model K1 is separated from the shoe model K3 by a certain distance or more in the height direction z.

If the ratio of the distances between the points P1 to P3 and the difference in curvature of the arch A between the foot model K1 and the standard model K2 are equal to or greater than the threshold, the calculation processing unit 212 adds the

pads

53a and 53b to the insole 51. placement can be determined. The

pads

53 a and 53 b may be attached to the upper surface of the insole 51 or embedded inside the insole 51 . Depending on the arrangement of the

pads

53a and 53b, the insole 51 can be provided with elasticity different from thickness.

The pad 53a is placed on the arch in order to maintain the shape of the arch A. The calculation processing unit 212 determines the shape and size of the pad 53a so as to fill the space between the upper surface of the insole 51 and the arch of the foot. Pad 53b is placed in the middle of the foot so that weight is applied to points P2 and P3. The calculation processing unit 212 adjusts the three-dimensional shape and size of the pad 53b so that the distance between the points P1 to P3 and the difference in curvature of the arch A between the foot model K1 and the standard model K3 are small. decide.

Instead of the insole 51, the

pads

53a and 53b may be pads arranged around the heel, instep, ankle, or the like. For example, if the foot has large unevenness, a pad may be arranged to fill the unevenness. The calculation processing unit 212 detects a recess where the size difference between the foot model K1 and the standard model K2 is greater than or equal to a threshold, and determines the three-dimensional shape and size of the pad so as to fill the recess.

Next, the calculation processing unit 212 calculates the elasticity and materials of the insole 51 and the

pads

53a and 53b according to the difference between the user's foot model K1 and the standard model K3 or the difference between the foot model K1 and the shoe model K3. to decide.

FIG. 7 shows an example of a table T1 that can be used to determine elasticity and material. Table T1 is stored in storage unit 22 .
In the table T1, elasticity and material are associated with the difference from the standard model K3 or the shoe model K2 for each part of the foot. In FIG. 7, when the foot model K1 is smaller and the difference is a negative value, it is indicated by (-).

For example, if the user's foot is longer than the standard size in the width direction x at the big toe, or if the distance from the foot to the shoe is short, the big toe is likely to hit the shoe. In order to reduce rubbing of the foot during walking, in Table T1, the difference between the foot model K1 and the standard model K3 is 10 mm or more, or the difference between the foot model K1 and the shoe model K2 (the distance from the foot to the shoe). is less than 10 mm, "soft" is associated with the elasticity, and "EVA (ethylene-vinyl acetate copolymer)" is associated with the material having this elasticity.

In this way, based on the table T1, the calculation processing unit 212 determines the elasticity of the insole 51 and the

pads

53a and 53b and the materials to be used from the difference between the user's foot size and the standard foot size or shoe size. The type of resin used can be determined.

Next, the calculation processing unit 212 calculates the arrangement position of the sensor 6 on the foot care product 5 (step S34). In FIG. 6B, asterisks exemplify the placement positions of the sensors 6 .
Specifically, the computation processing unit 212 computes the part where the foot is deformed due to the difference in three-dimensional size between the foot model K1 and the standard model K2. The calculation processing unit 212 determines the calculated site as the placement position of the sensor 6 .

For example, if the difference between the foot model K1 and the standard model K2 of the big toe is greater than a threshold value, the calculation processing unit 212 determines that a deformation in which the big toe protrudes in the width direction x, that is, a so-called hallux valgus, has occurred. 6 placement positions.

The calculation processing unit 212 can also calculate the part where the burden on the foot is predicted based on the difference between the foot model K1 and the shoe model K3, and determine the arrangement of the sensor 6 here. For example, when the instep is deformed to protrude upward, the distance in the height direction z from the instep to the shoe is short, and the foot is likely to be compressed. The calculation processing unit 212 compares the difference between the instep foot model K1 and the standard model K2 (the distance from the foot to the shoe) with a threshold, and if the difference is shorter than the threshold, the sensor 6 is placed on the shortest part. It can also be determined as a position.

Not limited to the above, the calculation processing unit 212 can also determine a position that affects walking as the placement position of the sensor 6 . For example, the points P1 to P3 can be determined as the placement positions of the sensors 6 in order to confirm whether the feet are supported at the points P1 to P3.

When walking, it is normal to touch the ground from the heel and kick up the ground with the toes while shifting the weight to the left and right outside of the foot. Lesions such as hallux valgus tend to occur when kicking. In order to predict such lesions, the heels, the left and right outer sides of the foot, the base of the toes, and the like, which are important points for walking, may be determined as the placement positions of the sensors 6 .

The sensor 6 of this embodiment is a pressure sensor, but a temperature sensor, a humidity sensor, or the like may be used.
Further, the sensor 6 of the present embodiment has wireless communication functions such as RFID (Radio Frequency IDentification System) and Bluetooth (registered trademark). This allows the sensor 6 to transmit the state of the foot to an external device such as the user terminal 1 at any time.

The sensor 6 may be embedded inside the foot care product 5 such as the insole 51 or the pad 53a, or may be arranged on the surface of the foot care product 5. The calculation processing unit 212 can determine an arrangement method that places less burden on the foot according to the type of the sensor 6 and the distance from the foot to the shoe.

FIG. 8 shows a sock 5A as an example of the foot care product 5. As shown in FIG.
The sock 5A is a separate type sock that separately accommodates the thumb and fingers other than the thumb. The sock 5A consists of an insole 51 and a sock body 52. - 特許庁The sock main body 52 is integrally formed by sewing a bottom part and two left and right parts. The insole 51 is arranged on the bottom surface of the sock body 52 . The size, thickness, material, etc. of the insole 51 and the size, shape, material, etc. of each part of the main body of the sock 52 are determined based on the design data as described above.

A plurality of sensors 6 are arranged on the sock 5A. The sensor 6 is also arranged at a position determined based on the three-dimensional size of the user's foot as described above. Some sensors 6 are embedded inside the insole 51 , while others are located on the outer surface or side of the sock body 52 .

　Detected data such as pressure output from the sensor 6 can be used to generate guidance data for the user's walking. The detection data can also be used to calculate design data when manufacturing new foot care products 5 .

FIG. 9 shows the flow of processing when providing guidance data in the foot care product providing system 100. As shown in FIG.
First, when the user terminal 1 receives detection data transmitted from the sensor 6 (step S11), it transmits the detection data to the data providing device 2 (step S12).

In the data providing device 2, the calculation processing unit 212 generates guidance data based on the transmitted detection data (step S13). Guidance data includes, for example, information on the walking condition of the user, information on lesions predicted in the future, advice on correct walking methods, and the like. The instructional data can include images, videos, etc. that describe the correct way to walk.

FIG. 10 shows an example of a table T2 that can be used to generate coaching data.
In table T2, instruction data is associated with the foot part and the level of pressure detected by the sensor 6 at that part.

For example, when the pressure detected at the position of the big toe is as high as 8 levels out of 10 and the pressure detected at the left and right outer positions is as low as 3 levels out of 10, the calculation processing unit 212 calculates from the table T2, " Acquire guidance data such as "Hallux valgus may progress", "Land on the heel and kick strongly with your fingertips".

The control unit 211 controls the communication unit 23 to transmit guidance data to the user terminal 1 that transmitted the detection data (step S14).
The user terminal 1 displays the transmitted guidance data (step S15). As a result, the user can grasp the current state of the foot and the pathology expected in the future, and it is possible to improve walking.

When ordering a new foot care product 6, the shape of the foot may have changed, so the user terminal 1 photographs the foot and generates new measurement data. Then, as shown in FIG. 3, the user terminal 1 transmits the data together with the order data to the data providing device 2. FIG. At this time, the user terminal 1 can also transmit the detection data of the sensor 6 together.

In the process shown in FIG. 3, the data providing device 2 can calculate the design data of the newly manufactured foot care product 5 based on the detection data transmitted from the user terminal 1. For example, if the pressure level on the bottom side of the big toe is higher than the threshold value according to the detection data, the calculation processing unit 212 calculates the design data based on the measurement data, and then reduces the elasticity of the insole at the position of the big toe by one level. data can be changed.

Design data may be calculated based not only on detection data at the time of ordering, but also on past detection data or guidance data generated from the detection data. As a result, it is possible to design foot care products 5 that better fit the foot based on past walking conditions and changes in the condition of the foot.

As described above, according to the present embodiment, the user terminal 1 transmits measurement data such as a photographed image of the foot to the data providing device 2 . The data providing device 2 calculates design data for the foot care product 5 based on the transmitted measurement data, and transmits the design data to the manufacturing system 3 . The manufacturing system 3 manufactures foot care products 5 based on the design data. The data providing device 2 uses the calculation processing unit 212 to calculate the size and elasticity of the foot care product 5, the arrangement position of the sensor 6, and the like.

Since the user terminal 1 can order and measure the foot care products 5, the user can order the foot care products 5 customized specifically for the user's feet by a simple procedure while staying at home. Even commercially available shoes can fit the feet by wearing the foot care product 5, so the variation of shoes that can be selected increases, and the degree of freedom in design increases. Among the foot care products 5, innerwear is less expensive than custom-made shoes, so the user's financial burden can be reduced.

Further, according to this embodiment, the detection data of the sensor 6 placed on the foot care product 5 can be transmitted from the user terminal 1 to the data providing device 2. The data providing device 2 generates guidance data on walking from the detection data and transmits the guidance data to the user terminal 1 . This allows the user to monitor the user's foot condition or walking condition. In addition, it is possible to appropriately determine replacement timing.

The detection data of the sensor 6 can also be used to calculate the design data of the foot care products 5 for the second and subsequent pairs. As a result, it is possible to provide the foot care product 5 which is improved so that the shoes fit the feet more easily and the walking is easily assisted.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications are possible within the scope of the present invention.

For example, in the above embodiment, the model K2 of a standard size shoe is used, but the user terminal 1 may photograph the shoe and transmit the image data to the data providing device 2 as measurement data of the shoe. In the data providing device 2, the calculation processing unit 212 can use the measurement data of the shoe to calculate the three-dimensional shape of the inner surface of the shoe and generate the model K2 of the shoe. The three-dimensional size of the inner surface of the shoe can be calculated in the same manner as the three-dimensional size of the foot. Since only the edge of the outer surface of the shoe can be detected from the image data, the calculation processing unit 212 can calculate the size of the inner surface by regarding, for example, 1 cm inside from the edge as the inner surface of the shoe.

The present invention is particularly useful for foot lesion patients who need their shoes customized, but can also be used by users without lesions. Although commercially available shoes may fit the length of the foot, the width and height may not match the foot, but according to the present invention, the foot care product 5 that can fit the foot to the shoe can be provided by a simple procedure. can be purchased. Guidance data can also be used to predict the occurrence of future lesions and improve walking methods.

In the above embodiment, the calculation processing unit 212 is implemented by software processing in which the CPU 21 reads and executes programs, but it may be implemented by hardware processing such as FPGA (Field-Programmable Gate Array). Also, a recording medium recording a program to be executed by a computer may be provided. The recording medium is not particularly limited as long as it is readable by computers such as CPUs and microcomputers, and semiconductor memories, magnetic disks, optical disks, and the like can be used.
