JP 2002-81912 A

  However, in the foot size measuring device described in Patent Document 1, since it is large, it can be used in a store or the like, but it is difficult for a customer to obtain and use it individually in terms of size and cost. was there.

  Therefore, the present invention has been made paying attention to such an unsolved problem of the conventional technology, and a foot size measuring system suitable for a customer to easily measure the size of a foot or shoes and It aims to provide a foot size measurement program.

  [Invention 1] In order to achieve the above object, the foot size measurement system according to Invention 1 is arranged on the foot placement medium by aligning the edge of the heel with the reference position periphery of the foot placement medium having a reference length periphery of a predetermined length. An image acquisition means for acquiring an image of the foot setting medium and the entire foot including the reference long periphery and the reference position periphery in a state where the sole is installed, from an image capturing means, and an image acquired by the image acquisition means Based on the conversion information generation means for generating conversion information for converting the actual length from the number of pixels, an image rotation means for rotating the image acquired by the image acquisition means in response to the rotation request, and an adjustment request A first slider interval adjusting unit that adjusts an interval between two first sliders that can slide in the first direction on the image acquired by the image acquiring unit or the image rotated by the image rotating unit; and an adjustment request Accordingly, the second slider interval for adjusting the interval between the two second sliders that can slide in the second direction orthogonal to the first direction on the image acquired by the image acquisition unit or the image rotated by the image rotation unit. Adjusting means; and foot size calculation means for calculating a foot or shoe size based on the conversion information generated by the conversion information generation means, the number of pixels between the first sliders, and the number of pixels between the second sliders. .

  With such a configuration, the foot image is acquired from the image capturing unit by the image acquiring unit. In this foot image, the foot setting medium including the reference long edge and the reference position edge and the entire foot are photographed with the sole of the foot placed on the foot setting medium with the edge of the heel aligned with the reference position edge of the foot setting medium. Has been. For this reason, conversion information is generated by the conversion information generation means based on the foot image.

  When the foot image is tilted, for example, the length direction of the foot in the foot image matches the sliding direction of the first slider, and the width direction of the foot in the foot image matches the sliding direction of the second slider. The foot image is rotated by the image rotating means. Then, the interval between the first sliders is adjusted so that one of the first sliders is located at the end of the toe and the other is located at the end of the toe. Similarly, the distance between the second sliders is adjusted so that one of the second sliders is positioned at the base of the thumb and the other is positioned at the base of the little finger.

  When the rotation and adjustment are performed in this way, the foot size calculation means calculates the size of the foot or shoe based on the generated conversion information, the number of pixels between the first sliders, and the number of pixels between the second sliders.

  Here, the first slider interval adjusting means may have any configuration as long as it adjusts the interval between the first sliders. For example, a configuration in which the two first sliders are arbitrarily slid, A configuration in which one of the sliders is fixed and the other is arbitrarily slid can be employed to widen or narrow the interval between the two first sliders. The same applies to the second slider interval adjusting means.

  The operation order of the conversion information generating unit, the image rotating unit, the first slider interval adjusting unit, and the second slider interval adjusting unit is not particularly limited and is arbitrary.

  Further, the present system may be realized as a single device, terminal, or other device, or may be realized as a network system in which a plurality of devices, terminals, or other devices are communicably connected. In the latter case, each component may belong to any one of a plurality of devices and the like as long as they are connected so as to communicate with each other.

  [Invention 2] Further, the foot size measurement system according to Invention 2 is the foot size measurement system according to Invention 1, wherein the foot installation medium is a sheet of a predetermined standard.

  With such a configuration, the foot or shoe size is calculated by photographing the paper and the entire foot with the soles placed on the paper of a predetermined standard.

  [Invention 3] On the other hand, in order to achieve the above object, the foot size measurement program according to Invention 3 is arranged so that the edge of the heel coincides with a reference position periphery of a foot installation medium having a reference long periphery of a predetermined length. An image acquisition step of acquiring an image of the foot setting medium and the entire foot including the reference long periphery and the reference position periphery with the sole placed on the image acquisition means, and the image acquisition step Based on the image, a conversion information generation step for generating conversion information for converting the actual length from the number of pixels, an image rotation step for rotating the image acquired in the image acquisition step in response to the rotation request, and an adjustment request In accordance with the first adjustment, the interval between the two first sliders that can slide in the first direction on the image acquired in the image acquisition step or the image rotated in the image rotation step is adjusted. Two second sliders that are slidable in a second direction orthogonal to the first direction on the image acquired in the image acquisition step or the image rotated in the image rotation step in response to an adjustment request. The size of the foot or shoe is adjusted based on the conversion information generated in the conversion information generation step, the number of pixels between the first sliders, and the number of pixels between the second sliders. A program for causing a computer to execute processing including a foot size calculation step to be calculated.

  With such a configuration, when the program is read by the computer and the computer executes processing in accordance with the read program, an operation equivalent to that of the foot size measurement system of the invention 1 is obtained.

  Here, the first slider interval adjusting step may have any configuration as long as it adjusts the interval between the first sliders. For example, the first slider interval may be arbitrarily slid, A configuration in which one of the sliders is fixed and the other is arbitrarily slid can be employed to widen or narrow the interval between the two first sliders. The same applies to the second slider interval adjustment step.

  The execution order of the conversion information generation step, the image rotation step, the first slider interval adjustment step, and the second slider interval adjustment step is not particularly limited and is arbitrary.

  As described above, according to the foot size measurement system of the invention 1 or the foot size measurement program of the invention 3, for example, a foot image is taken with a mobile terminal such as a smartphone, and the image is rotated or adjusted on the mobile terminal. Accordingly, the size of the foot or the shoe can be measured, so that the customer can easily measure the size of the foot or the shoe as compared with the conventional case. Also, if the foot image is tilted, for example, even if the distance between the first sliders is adjusted so that one of the first sliders is located at the toe end and the other is located at the end of the toe, Although the length of the foot is calculated with a different length, the image can be rotated to correct the inclination, so that the size of the foot or the shoe can be measured relatively accurately. Compared to a configuration that automatically measures the size of all feet or shoes, it is easier for the user to adjust the slider so that the user can be satisfied with the measurement results, which leads to subsequent purchases of shoes, etc. The possibility (contract rate) can be improved.

  Furthermore, according to the foot size measuring system of the invention 2, paper of a predetermined standard can be used, so that the customer can more easily measure the size of the foot or shoe. Further, since the paper is a color having contrast with the colors of the feet and socks, the feet can be grasped relatively clearly on the image.

  As with the right foot, the user places the left sole on the foot placement paper with the bottom edge of the foot placement paper aligned, and places the foot so that the entire foot placement paper and left foot fit within the screen. A shutter operation is performed on the mobile terminal 100 by tapping the shooting button 42 in a state where the corners of the paper are aligned with the guide 40. In step S120, an image obtained by photographing the entire foot placement sheet and the left foot (hereinafter referred to as “left foot image”) is acquired from the photographing unit 24, the process proceeds to step S122, and the foot placement sheet is obtained based on the obtained left foot image. It is determined whether or not each corner has been detected. If it is determined that each corner of the foot placement sheet has been detected (YES), the process proceeds to step S124.

  In step S124, the number of pixels from the upper left corner to the lower left corner of the detected foot placement paper and the number of pixels from the upper right corner to the lower right corner are calculated, and the average value is calculated as the number of pixels on the long side of the foot placement paper. The actual length ratio is calculated by dividing the actual length of the long side of the foot setting paper by the number of pixels of the long side of the foot setting paper, and the process proceeds to step S126.

  When the left foot image is tilted, the user can rotate the left foot image by performing an operation such as a roll. Here, the user rotates the right foot image so that the length direction of the left foot in the left foot image matches the vertical direction of the screen, and the width direction of the left foot in the left foot image matches the horizontal direction of the screen. In step S126, it is determined whether or not the user has input a rotation request for the left foot image from the detection unit 21 by performing an operation such as a roll. If it is determined that the rotation request has been input (YES), the process proceeds to step S128. The process proceeds to rotate the left foot image by an angle corresponding to the amount of roll operation, and the process proceeds to step S130.

  On the left foot image, two vertical sliders 44a and 44b slidable in the vertical direction and two horizontal sliders 44c and 44d slidable in the horizontal direction are displayed. The user can move the vertical sliders 44a and 44b on the left foot image by performing an operation such as sliding. Here, the user adjusts the vertical sliders 44a and 44b so that the upper vertical slider 44a is positioned at the toe end and the lower vertical slider 44b is positioned at the end of the toe. In step S130, it is determined whether or not the user has input a vertical slide request from the detection unit 21 by performing an operation such as a slide. If it is determined that a vertical slide request has been input (YES), the process proceeds to step S132. Then, the vertical sliders 44a and 44b related to the vertical slide request are moved in the vertical direction by a distance corresponding to the slide operation amount, and the process proceeds to step S134.

If it is determined in step S122 that any corner of the foot setting paper cannot be detected (NO), the left foot image needs to be re-captured, and the process proceeds to step S120.

Next, the effect of this embodiment will be described.
In the present embodiment, a foot image obtained by photographing the foot setting paper and the entire foot in a state where the edge of the heel is aligned with the lower side of the foot setting paper and the sole is placed on the foot setting paper is acquired from the photographing unit 24. Based on the foot image, calculate the actual length ratio by dividing the actual length of the long side of the foot setting paper by the number of pixels of the long side of the foot setting paper, rotate the foot image in response to the rotation request, Two vertical sliders 44a and 44b that can slide in the vertical direction on the foot image in accordance with a slide request are moved respectively, and two horizontal sliders 44c and 44d that can slide in the horizontal direction on the foot image in response to a horizontal slide request. , And the foot and shoe sizes are calculated based on the actual length ratio, the number of pixels between the vertical sliders 44a and 44b, and the number of pixels between the horizontal sliders 44c and 44d.

  Thereby, since the user who is a customer can measure the size of the foot and shoes by taking a foot image with his / her mobile terminal 100 and rotating or sliding the foot image on the mobile terminal 100, In comparison, customers can easily measure foot and shoe sizes. In addition, pregnant women and the like can make measurements with an easy posture without excessive posture. Further, if the foot image is tilted, for example, even if the vertical sliders 44a and 44b are moved so that the upper vertical slider 44a is positioned at the toe end and the lower vertical slider 44b is positioned at the end of the toe, Although the length of the foot is calculated with a length different from the actual length, the foot image can be rotated to correct the inclination, so that the size of the foot and shoes can be measured relatively accurately. Compared to a configuration that automatically measures the size of all feet and shoes, it is easier for the user to perform the operation of moving the slider, so it is easier to convince the measurement result, which leads to subsequent purchase of shoes, etc. The possibility (contract rate) can be improved. If it becomes easier for the user to be satisfied with the measurement result, the return rate will decrease when shoes are sold by mail order.

  Further, in the present embodiment, a paper of a predetermined standard (for example, A4 size) is used as the foot setting paper.

  Thereby, since the paper of the predetermined standard which is easy to obtain can be used, the customer can more easily measure the size of the foot and the shoe. Further, since the paper has a color that contrasts with the colors of the feet and socks, the feet can be grasped relatively clearly on the foot image.

  In the present embodiment, the photographing unit 24 corresponds to the image photographing unit of the first or third aspect, and steps S100 and S120 correspond to the image obtaining unit of the first aspect or the image obtaining step of the third aspect.

[Modification]
In the above embodiment, the adjustment of the contrast of the foot image has not been described. For example, when it is determined that the contrast between the color of the foot installation paper and the color of the foot in the foot image is less than a predetermined value. The foot image can be re-captured. Thereby, since a certain contrast can be ensured, the foot can be grasped more clearly on the foot image.

  Further, in the above-described embodiment and the modification thereof, the foot installation paper having a size larger than the foot is used, but the present invention is not limited to this, and has a reference long periphery (for example, a periphery composed of a straight line or a curve). If it is paper, foot installation paper having a size smaller than that of the foot can be used.

  Further, in the above-described embodiment and its modified examples, the paper of a predetermined standard is used as the foot setting paper. However, the present invention is not limited to this, and an arbitrary medium may be used as long as it has a predetermined long reference long edge. it can.

  Moreover, in the said embodiment and its modification, although the size of the foot | leg and shoes was calculated, it is not restricted to this, You may calculate only the size of a foot | foot, You may calculate only the size of shoes. In the latter case, the shoe size can be calculated based on the actual length ratio, the number of pixels between the vertical sliders 44a and 44b, and the number of pixels between the horizontal sliders 44c and 44d, without calculating the foot size.

  Further, in the above-described embodiment and its modification, the foot and shoe sizes are calculated for the right foot and the left foot. However, the present invention is not limited to this, and it may be calculated only for the right foot or only for the left foot. .

  Further, in the above-described embodiment and its modification, the actual length ratio is calculated with the long side of the foot setting paper. However, the present invention is not limited to this, and can be calculated with the short side. When calculating on the short side, calculate the number of pixels from the upper left corner to the upper right corner (the number of pixels on the upper side) and the number of pixels from the lower left corner to the lower right corner (the number of pixels on the lower side), and average the values. Is calculated as the number of pixels on the short side of the foot setting paper, and the actual length ratio is calculated by dividing the actual length of the short side of the foot setting paper (210 [mm] for A4 size) by the number of pixels on the short side of the foot setting paper. Is calculated. However, the actual length ratio can be calculated with higher accuracy than the short side because the longer side has a larger number of pixels.

  Further, in the above-described embodiment and its modification, the case where the program stored in advance in the storage unit 25 is executed when executing the foot size measurement process shown in the flowchart of FIG. Instead, the program may be read from a storage medium storing the program showing these procedures and executed.

  Further, in the above-described embodiment and the modification thereof, the display of the shoe information of shoes purchased by other users has not been described. For example, a foot image captured by the user's own mobile terminal 100 is displayed by another user. It can also be configured to display shoe information of shoes purchased by a user of a foot image close to his / her own foot image by comparing with a foot image taken by the portable terminal 100 of the user. Specifically, the following configuration can be employed.

  The shoe information management server includes a foot image database for registering foot images taken by the user's mobile terminal 100 for each user, and shoe information (for example, size, manufacturer, product number, etc.) about shoes purchased by the user for each user. A shoe information database for registering the current sales price, purchase price, purchase quantity, purchase frequency, product image, review), and the foot images of other users similar to the foot images taken by the mobile terminal 100 of user A It searches from the foot image database, searches the shoe information database for the user's shoe information corresponding to the searched foot image, and transmits the searched shoe information to the mobile terminal 100 of the user A. The portable terminal 100 displays the shoe information received from the shoe information management server. Thereby, since the user can refer to the shoe information of shoes purchased by other users close to his / her own foot or shoe size, the purchase of the user's shoes can be promoted. For example, another user close to your foot or shoe size has purchased a shoe that is slightly larger than the size measured in the foot size measurement application and has written a highly satisfactory review for the item. Is motivated to buy shoes that are slightly larger than the measured size.

  In this configuration, collation with the foot image is performed. However, instead of the foot image, collation with size information including the calculated foot or shoe size may be performed. Also, if there is a tendency to purchase shoes that are slightly larger than the size measured by the foot size measurement application from the shoe information in the shoe information database, select a size that is slightly larger than the measured size. It is also possible to correct the determination criterion in step S144 so as to display “ Similarly, if there is a tendency to purchase shoes that are slightly smaller than the measured size and be satisfied, the criterion in step S144 is corrected so as to present a size slightly smaller than the measured size as the “recommended shoe size”. can do. This correction can be made for each shoe size, application, user gender and other segments.

  Moreover, in the said embodiment and its modification, although determination about the suitability of the size of a foot | leg or shoes was not demonstrated, for example, the foot image image | photographed with the own portable terminal 100 is another user's portable terminal. Compared with the foot image taken at 100, the size of the calculated foot or shoe is different from the foot or shoe size calculated for the user of the foot image close to the own foot image by a predetermined amount or more. If so, it may be configured to notify that the calculated foot or shoe size may be incorrect. Specifically, the following configuration can be employed.

  The size information management server registers a foot image database for registering a foot image captured by the user's portable terminal 100 for each user, and a size information for registering size information including the foot or shoe size calculated for the user for each user. An information database, the foot image database of another user that is similar to the foot image captured by the mobile terminal 100 of the user A is searched from the foot image database, and the size information of the user corresponding to the retrieved foot image is obtained from the size information database. The size information retrieved and retrieved is transmitted to the mobile terminal 100 of the user A. Here, when the size information of a plurality of users is searched, a statistical value (for example, an average value) of the foot or shoe size calculated for these users is calculated, and the size information including the statistical value is stored in the mobile terminal. To 100. Based on the size information received from the size information management server, the mobile terminal 100 determines that the calculated foot or shoe size is predetermined compared to the foot or shoe size calculated for another user or its statistical value. If it is determined whether or not a difference has occurred, and it is determined that a difference has occurred more than a predetermined amount, a predetermined notification (for example, a notification that the calculated foot or shoe size may be incorrect) I do. Thereby, the user can grasp the suitability of the size of the calculated foot or shoe.

  In this configuration, the predetermined notification is performed. However, the present invention is not limited thereto, and the calculated foot or shoe size may be corrected based on the received size information.

  Also, in the above embodiment and its modifications, the description has not been made about the variation in the size of the foot. However, since the size of the foot varies, for example, during the day, the shoe to be purchased is used. It is conceivable to measure the size of the foot or shoe in consideration of the period of time. Specifically, the following configuration can be employed.

Here, the usage period information can set, for example, a specific time zone in one day, a specific day in one week, a specific day in one month, a specific period in one year, and other arbitrary periods. . In addition, the usage period information may set a period during which the shoe is generally or statistically used, or may set a period that the user actually uses or is expected to use for each user. Good. In the latter case, for example, a sensor can be provided on the shoe, and the usage period information can be set based on information obtained from the sensor.

  In the second configuration, for each measurement, size information including the size of the foot or shoe and the measurement date / time is recorded in the storage unit 25, and the usage period information of the shoe that the user intends to purchase is acquired from the server and acquired. Based on the usage period information, the size information in the storage unit 25 is read from the storage unit 25 and the size information to which the measurement date belongs within the period in which the shoe that the user intends to purchase is used, and based on the read size information. The “recommended shoe size” is displayed for the shoe that the user intends to purchase.

  In the third configuration, for each measurement, size information including the size of the foot or shoe and the measurement date / time is recorded in the storage unit 25, and the usage period information of the shoe that the user intends to purchase is acquired from the server. Based on the usage period information and the size information in the storage unit 25, the user's foot or shoe size is predicted within the period in which the shoe to be purchased is used, and the user purchases based on the prediction result. “Recommended shoe size” is displayed for the shoe to be used.

  Also, in the above embodiment and its modification, the description has not been made about the variation in the foot size, but the size of the foot varies depending on the condition or situation when using the shoes, so it is intended to purchase. It is conceivable to measure the size of the foot or shoe in consideration of the use of the shoe. Specifically, the following configuration can be employed.

  In the first configuration, usage information indicating the usage of each shoe is stored in the database of the server, the usage information of the shoe that the user intends to purchase is acquired from the server, and based on the acquired usage information, Alternatively, the condition or situation (current) in which the size of the shoe is to be measured is not the condition or situation (hereinafter referred to as “condition or situation at the time of use”) when the user uses the shoe for the intended use of the shoe. If it is determined, a predetermined notification (for example, notification that it is better to measure in the condition or situation when using the shoe to be purchased) is performed. Here, as the usage information, for example, commuting, attending school, exercising, leisure, outdoor, or any other usage can be set. In addition, the usage information may set a general or statistical usage of the shoe, or may set a usage that the user actually uses or is expected to use for each user. In the latter case, for example, a sensor can be provided on the shoe, and application information can be set based on information obtained from the sensor. Further, the user's condition can be specified from the user's physical information (for example, heart rate, blood pressure, blood glucose level) obtained from the sensor, and the user's situation can be specified from the position information of the portable terminal 100 or the like. The condition or situation at the time of use can be specified by a table or the like in which condition information indicating the condition or situation and usage information are registered in association with each other.

  In the second configuration, for each measurement, size information including the size of the foot or shoe and the condition or situation at the time of measurement is recorded in the storage unit 25, and the usage information of the shoe that the user intends to purchase is acquired from the server. Then, based on the acquired use information, the size information of the storage unit 25 is read from the storage unit 25, and the size information of the condition or the situation that is close to the condition or the situation at the time of use of the shoe that the user intends to purchase is read from the storage unit 25. Based on the information, the “recommended shoe size” is displayed for the shoe that the user intends to purchase.

  In the third configuration, for each measurement, size information including the size of the foot or shoe and the condition or situation at the time of measurement is recorded in the storage unit 25, and the usage information of the shoe that the user intends to purchase is acquired from the server. Then, based on the acquired usage information and the size information of the storage unit 25, the size of the user's foot or shoes in the condition or situation when using the shoe that the user intends to purchase is predicted, and based on the prediction result, The “recommended shoe size” is displayed for the shoe that the user intends to purchase.

  In these configurations, the use information is used, but in place of the use information, condition information indicating the condition or situation when using the shoes can be used.

  In addition, since the size of the foot varies depending on the weight of the user, it is conceivable to measure the size of the foot or shoes in consideration of the weight of the user. When the weight increases, the size of the foot increases, whereas when the weight decreases, the size of the foot decreases. Specifically, the following configuration can be employed.
