Insole data generation system and insole data generation method

The present invention relates to an insole data generation system and an insole data generation method, and particularly based on a user's walking habits extracted from a user's walking video taken by a user terminal, structural data of an insole for correction suitable for the user. The present invention relates to an insole data generation system and an insole data generation method.

Walking is one of the most basic movements for humans, but many people tend to have a habit of walking as a result of walking without being particularly conscious of their walking posture for many years. The habit of walking usually appears as a tilt of the body, and in a continuous walking motion, it is observed as a swing during walking in which the body leans to one side or left and right.
Such walking habits may occur not only when the walking habits are accumulated for many years, but also when it is difficult to take a correct walking posture due to the influence of illness or injury.

If the habit of walking is mild, the effect on the body is small, but if the degree is severe, a biased load is applied to the knees and hips, and the effects of joint inflammation and pain are likely to occur. Therefore, it is important for people with strong walking habits to correct their walking habits before they affect the body.
In order to correct walking habits, it is common to form an insole, which is an insole to be put in shoes, into a shape that gives a corrective effect. An insole shaped to have a corrective effect is also called a sole plate, and it is necessary to individually manufacture it according to the walking habit of the user who uses it, and for that purpose, first the user's walking habit You need to figure it out.
The habit of walking can be grasped to some extent by the decrease in the soles of the shoes that are usually worn, but it is not possible to grasp exactly where and how to correct it.

In Patent Document 1, an insole in which a pressure-sensitive sensor and transmission / reception means are arranged at a plurality of predetermined locations is attached to the inside of a shoe desired as a test insole, and the pressure applied to the sole of the foot during walking is measured by the pressure-sensitive sensor. A method and a system for producing a new insole in which a pressure-sensitive sensor and a transmission / reception means are arranged are disclosed.

According to Patent Document 1, since it is possible to accurately evaluate where and what kind of pressure is applied while the user is walking, it is expected to manufacture an insole that matches the walking habit of the user. However, in order to carry out Patent Document 1, the user must first obtain a test insole and walk for pressure measurement, and a new insole created based on the pressure measurement result also has a pressure sensor and a pressure sensitive insole. Since the transmission / reception means are arranged, the production cost is high, the production place is limited, and the user has to wait for the finished product to be sent. Furthermore, there is a problem that repeat orders are subject to the same restrictions.
Therefore, an insole data generation system and an insole data generation method that can easily grasp the user's walking habits and easily produce repeats without preparing a special tool such as a pressure sensor. Expected to be provided.

FIG. 1 is a block diagram schematically showing a configuration of an insole data generation system according to an embodiment of the present invention.
Referring to FIG. 1, the insole data generation system 1 according to the embodiment of the present invention includes an information providing server 10 and a user terminal 20 connected via a network 50. Although only one user terminal 20 is shown in FIG. 1, the number of user terminals 20 is arbitrary and basically a plurality.

The insole data generation system 1 according to the embodiment of the present invention generates and provides structural data of an insole suitable for the user based on the walking habit of the user extracted from the walking video of the user taken by the user terminal 20. It is a system to do.
If one is not aware of maintaining the correct posture when walking, one may develop a habit of walking with one shoulder down or the knee bent inward or outward. When the degree of walking habits becomes severe, local pain and other effects are likely to occur on the body, so insoles that are put in shoes to correct walking habits have been used. Until now, insole production has required time-consuming preparations such as detailed measurement of the foot size of the user who desires the insole and pressure measurement of the sole of the foot.

The insole data generation system 1 according to the present invention reduces the time and effort required for such advance preparation, and makes it easy for the user to manufacture an insole even from a remote location without going to an orthopedic clinic or the like to have the user manufacture an insole for correction. It provides an environment where you can apply for.

According to the insole data generation system 1 according to the present invention, a user who needs to use the insole can simply shoot a moving image of his / her walking by the user terminal 20 and implement an application program (hereinafter referred to as an application) on the user terminal 20. Since the user's walking habits are extracted from the moving image taken by (referred to as) and transmitted to the information providing server 10, the user can easily acquire the basic data for manufacturing the insole.

The information providing server 10 that has received the user's walking habit from the user terminal 20 calculates the correction amount for correcting the walking habit based on the received walking habit, and obtains the pad structure data for correction. Generate and generate structural data for the orthodontic insole that incorporates pad structure data into a standard insole that fits the shoe size, based on the user's basic information, including the user's shoe size pre-populated. Since the generated insole structure data is configured as input data of the 3D printers (30, 31) and output to the user terminal 20, when the user owns the 3D printer 30, the insole structure data received as it is is used. You can make an insole on the spot. Even if you do not own the 3D printer 30, you can provide the structural data of the insole received to a store such as a shoe store where the nearest 3D printer 31 is installed and have it manufactured.

In this way, the insole data generation system 1 is a system that can acquire data very easily without using a special tool, and even a user in a remote place can easily manufacture an insole.

Referring to FIG. 1, the information providing server 10 includes a control unit 11, an input / output unit 12, a storage unit 13, a display unit 14, a user registration unit 15, a walking data management unit 16, a pad structure data generation unit 17, and an insole structure data. A generation unit 18 and a 3D printer data generation unit 19 are provided.

When the user uses the insole data generation system 1 for the first time, the user registration unit 15 receives the user's basic information such as the user's name and e-mail address transmitted from the user terminal 20, and as a new user member, each user A user ID, which is a unique identifier, is issued and stored in the storage unit 13 together with the basic information of the user for management. In the embodiment, the basic information of the user is provided to the user registration unit 15 by presenting an input format so as to input necessary items in the website provided by the information providing server 10 and inputting and transmitting the user. Will be done. The basic information of the user includes information necessary for manufacturing the insole such as the size of the user's shoes.

In one embodiment, in order to fit the shape of the insole to a shape more suitable for the user's foot, the information necessary for manufacturing the insole includes image data of the front and side surfaces of the foot under the load state of the foot. The image data of the front surface and the side surface of the foot under the load state of the foot is used to acquire the data of the foot width of the user and the vertical arch shape of the foot. The image data of the front surface and the side surface of the foot may be presented to the user by an application implemented in the user terminal 20 to encourage the user to take a picture. It is preferable that the image data of the front surface and the side surface of the foot are taken with each of the left and right feet, and the image of the side surface is taken so as to include the left side surface and the right side surface.
The image data of the front and side surfaces of the foot received from the user terminal 20 may be stored and managed by the user registration unit 15 as it is in the storage unit 13 as a part of the basic information of the user, or may be managed by the information providing server 10. An image analysis unit (not shown in FIG. 1) is further provided, and the user's foot width and the vertical arch shape data of the foot are extracted from the image data of the front and side surfaces of the foot, and the extracted user's foot width and foot are extracted. The data of the vertical arch shape of the unit may be stored and managed in the storage unit 13 as a part of the basic information of the user. In another embodiment, the image data of the front surface and the side surface of the foot in the unloaded state of the foot are further included, and the difference between the data of the foot width and the vertical arch shape of the foot in the loaded state and the unloaded state is extracted. , It is stored and managed in the storage unit 13 as a part of the basic information of the user so as to be the reference data at the time of creating the insole.
Further, the basic information of the user may include information such as the height of the user so as to be referred to when calculating the correction amount for correcting the habit of walking.

The walking data management unit 16 receives the walking habit of the user extracted by the application implemented in the user terminal 20 from the walking video of the user taken by the user terminal 20, and associates it with the user ID in the storage unit 13. Save and manage in.
Here, the walking video of the user is a video shot from the front or the back of the user and includes walking movements by at least the left and right feet, and is preferably a video including walking of at least two or three steps on each of the left and right feet. .. Further, the habit of walking is a change in the inclination of the central axis or the reference line of a predetermined position of the body observed from the front or the back of the walking user. The central axis or reference line at a predetermined location includes, for example, the axis of the trunk, which is the central axis of the torso, the reference line of the shoulder, the reference line of the pelvis, the reference line of the knee, the reference line of the foot, and the like.

In the above embodiment, the walking habit is extracted by the application implemented in the user terminal 20, but in other embodiments, the walking video of the user taken by the user terminal 20 is stored in the user terminal 20. After that, it is transmitted to the information providing server 10 as it is without extracting the habit of walking. Therefore, the walking data management unit 16 is provided with a means for extracting the walking habit from the walking video, extracts the walking habit from the walking video of the user received from the user terminal 20, and associates it with the user ID of the user to store the habit. Save and manage in 13.

In one embodiment, the extraction of walking habits is performed by determining the inclination of the central axis or the reference line of a predetermined part of the body from the timing of landing of the foot to the timing of kicking the foot and leaving the ground. It should be acquired according to how to attach to or at a predetermined time interval.
Further, in one embodiment, the walking data management unit 16 superimposes a central axis or a reference line of a predetermined portion of the user's body used when extracting a walking habit on the walking video of the user, and the user walks. It provides a visualization of how the central axis and reference line are tilted inside. This can be realized, for example, by providing a unique information page for each user as a user's My Page in the Web site provided by the Information Providing Server 10, and providing the information page so that it can be viewed in the My Page. Furthermore, the habit of walking is similarly extracted from the walking video when walking using the insole manufactured using the insole data generation system 1, and the degree of improvement in the inclination of the axis and the reference line before and after using the insole is improved. It may be provided so that it can be visualized. By doing so, the user can easily grasp his / her walking habits and focus on improving his / her walking posture.

In addition, the walking video needs to be recorded so that the whole body of the user is included in the walking video in order to correctly identify the central axis and the reference line of a predetermined part of the body, but if the height of the user is known, the walking video needs to be recorded. Since the user's walking distance, walking speed, and stride can be calculated from the walking time from the start to the end of walking and the angle and number of steps of the user's whole body, it is used as the user's walking data in My Page of the above website. Walking speed, stride length, etc. may be provided. Further, the walking data management unit 16 may encourage the user to shoot a moving image in which the walking speed is changed, obtain a difference in walking habits due to the difference in walking speed, and reflect the result in the production of the insole.

The pad structure data generation unit 17 acquires the user's walking habit from the walking data management unit 16, calculates the correction amount for correcting the walking habit based on the walking habit, and calculates the correction amount of the pad structure data for correction. To generate. For example, if the user has a habit of leaning to the right when walking, correct the pad to be inserted on the outside of the right foot. At that time, the height of the pad is obtained by referring to the value of the inclination of the central axis or the reference line at a predetermined position of the user's body during walking so that the inclination disappears. In addition, if the data on walking habits is acquired in correspondence with the landing state of the foot or the passage of time, it is possible to calculate how much correction is required at which position in the front-back direction of the foot. Finer fitting is possible.

The pad structure data generated by the pad structure data generation unit 17 is set higher as the position where the pad is installed is farther from the center line of the shoe in order to correct the inclination during walking. Therefore, in the embodiment, the pad structure data generation unit 17 calculates the required pad height according to the standard shoe size. In another embodiment, the user's shoe size and foot front and side image data entered during user registration, or the user's foot width and vertical arch shape of the foot extracted from these image data. It is configured to refer to the data and calculate the pad height according to the size of the user's shoes.

The pad structure data is based on the amount of correction that corrects habits during walking, and it is desirable to use an insole that includes the generated pad structure data in the end, but depending on the user, an ideal insole may be used suddenly. It may cause discomfort when used. Therefore, in one embodiment, in addition to the pad structure data of the ideal height, the pad structure data in which the height is changed to the plus side and the minus side is generated, and the data of the insole incorporating these data can be selected by the user. To provide to. This also enables the user to gradually improve the walking posture.

The insole structure data generation unit 18 incorporates the pad structure data acquired from the pad structure data generation unit 17 into a standard insole that matches the shoe size based on the user's shoe size information, and obtains structural data of the insole for correction. Generate.
If the pad structure data is generated in a form that matches the standard shoe size, the insole structure data generator 18 selects a standard insole that matches the user's shoe size, and then the standard shoe. The pad structure data is corrected based on the ratio of the size of the insole to the size of the user's shoes so that the pad structure data is placed on the selected insole, and the structure data of the insole for correction incorporating the pad structure data is generated. When the pad structure data is generated as pad data according to the foot width and the vertical arch shape obtained from the image data of the user's shoe size and the front and side of the foot, the insole structure data generation unit 18 may generate the pad structure data. The pad structure data is directly incorporated into the standard insole that matches the size of the user's shoe, and the structure data of the insole is generated.

The 3D printer data generation unit 19 configures and outputs the structural data of the insole as input data of the 3D printers (30, 31). There are various models of 3D printers (30, 31) on the market, from desktop type for personal use to large equipment for business use, but if the data is configured in the format called STL (Standard Triangled Language) format, it is basic. Any model can read data and perform 3D processing. Therefore, the 3D printer data generation unit 19 configures the insole structure data generated by the insole structure data generation unit 18 as STL format data, and outputs the data to the user terminal 20 that has applied for the generation of the insole data.

As a result, the user can perform 3D processing at the nearest store equipped with the 3D printer 30 or 3D printer 31 owned by the user and immediately obtain the insole. Of course, if you are a remote user and neither you nor the stores in the vicinity own a 3D printer (30, 31), make an insole with the 3D printer owned by the administrator of the information providing server 10 and use the completed insole. It may be delivered to the user.

The input / output unit 12 is a communication means for receiving the user's basic information, the user's walking video or walking habit from the user terminal 20, and transmitting the generated insole structure data for a 3D printer, and the communication means.

In order to grasp the walking habit as accurately as possible, the user may be instructed to shoot the walking moving image a plurality of times by an application implemented on the user terminal 20. Further, in another embodiment, the user may be instructed to walk a predetermined distance several times, and a plurality of moving images may be collectively shot in one shooting.

Next, in step S420, the walking data management unit 16 of the user terminal 20 or the walking data management unit 27 of the information providing server 10 that has received the walking video from the user terminal 20 extracts the walking habit of the user. To extract habits during walking, the outer shape of a pedestrian is recognized by image recognition, and the central axis or reference line of a predetermined part of the body such as the trunk axis 200 or the shoulder reference line 210 is obtained, and these central axes or reference lines are obtained. It can be extracted by finding the slope of the reference line with the vertical line or the horizontal line. When a plurality of walking videos are taken as described above, more accurate walking habits can be extracted by obtaining the average inclination of each central axis and reference line. In addition, when a round-trip walking video is taken, the outward route and the inbound route are each extracted as one walking video, and the average walking habit is extracted as described above.

The extracted walking habit is sent to the pad structure data generation unit 17 of the information providing server 10, and the pad structure data generation unit 17 corrects the walking habit based on the walking habit in step S430. The amount is calculated to generate pad structure data for correction. Pad structure data is calculated as the height of the pad relative to standard size shoes. When calculating the correction amount, the user's shoulder width and pelvis width are obtained with reference to the user's height entered at the time of user registration, and the difference between the left and right heights of the shoulder and pelvis is calculated to calculate the correction amount. You may use it.

The insole structure data generation unit 18 of the information providing server 10 has the user's shoe size and foot front and side image data input in advance in step S440, or the user's foot width extracted from these image data. Based on the data of the vertical arch shape of the foot, the structural data of the insole for correction is generated by incorporating the pad structure data into the standard insole suitable for the shoe size. When incorporating the pad structure data, the insole structure data generation unit 18 corrects the height of the pad in the pad structure data due to the difference between the standard size shoe and the user's shoe size.

Finally, in step S450, the 3D printer data generation unit 19 of the information providing server 10 configures the structural data of the insole as input data of the 3D printers (30, 31) and outputs it to the user terminal 20.

When the user who receives the structural data of the insole actually manufactures the insole, the user transmits the input data of the 3D printer (30, 31) which is the structural data of the received insole to the 3D printer 30 owned by the user. (Step S460) Processing is performed (step S470).
If the user does not own the 3D printer 30, the user can go to the nearest store equipped with the 3D printer 31 or send the data to the nearest store to have the insole manufactured.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments and is variously modified within a range that does not deviate from the technical scope of the present invention. It is possible to do.
