The present invention is a user terminal 100 for measuring length and width by photographing a user's foot placed on the paper while matching the paper to the reference frame displayed on the screen, and shoes suitable for the user based on the measured length and width. It relates to a system configured including a web server 200 for screening and providing.

A user who wants to use the foot size-based shoe size calculation system according to the present invention must install a measurement application distributed online on his terminal, and execute the installed measurement application to take a procedure for measuring his foot size. You can.

In other words, the user terminal 100 in the present invention means a terminal such as a smartphone on which the measurement application is installed, and a data communication function and a user's data communication function for bidirectional communication with the web server 200 by installing the measurement application. It is assumed that a photographing function for photographing a foot is essentially provided.

In addition, the web server 200 in the present invention means a server used for opening and operating a web page on the Internet, and a data storage space for posting various types of shoes on the Internet and the above It is assumed that a data communication function for bidirectional communication with the user terminal 100 is essentially provided.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, as illustrated in FIG. 1, when the photographing function of the user terminal 100 is activated, the user terminal 100 of the foot size-based shoe size calculation system according to the present invention has the same paper and ratio but different sizes. Characterized in that it comprises a reference frame display unit 110 for generating a reference frame to display on the screen.

The reference frame display unit 110 is activated only when a user selects a separate menu for measuring the foot size after the measurement application installed in the user terminal 100 is driven, and the horizontal and vertical lengths of the paper set as a reference. According to this, it is an element of the present invention that derives the aspect ratio of the paper, and reflects the resolution of the camera, thereby generating a reference frame composed of the same and different sizes of the paper.

That is, the reference frame is a line on the screen used as a reference for adjusting the distance and angle between the camera and the paper, and is preferably configured in the same square shape as the general paper, but a part of each side except for each corner is omitted. It may be used in various forms such as form.

Specifically, as shown in FIG. 3, the reference frame display unit 110 extracts the application database 111 in which the horizontal and vertical lengths according to the type of paper are stored, and the camera resolution of the user terminal 100. The unit 112 includes a frame-generating unit 113 that forms a reference frame of the same size but different size by applying the extracted camera resolution to the horizontal and vertical lengths of the paper selected or input by the user. It is characterized by being.

The paper used as a standard for setting the horizontal and vertical lengths of the reference frame includes A4, B4, etc., standardized paper, and any other paper. A4 paper mainly used in real life is set as a standard. Although this is preferable, the user can change the setting to B4 paper, B5 paper, etc. as needed, and the user can set and change the size of the paper for forming the reference frame by measuring the horizontal and vertical lengths of the paper and directly inputting it.

Therefore, in the application database 111, the horizontal and vertical lengths of standardized papers such as A4 and B4 are pre-inputted and stored, and the horizontal and vertical lengths of the paper input by the user are newly stored so that the reference frame generation unit 113 The extraction unit 112 extracts the resolution of the camera provided in the user terminal 100 so that it can be used in the reference frame generation unit 113. Any one of the methods in which the extracted resolution is stored in the application database 111 and continuously utilized may be applied.

In addition, as shown in Figure 1, the user terminal 100 is characterized in that it comprises a photographing unit 120 for generating photo information by photographing the foot of the user on the paper, the photographing unit ( 120) drives a camera provided in the user terminal 100, and photographs only a screen within the reference frame range among screens displayed on the screen of the user terminal 100 to generate photo information, and includes images included in the photo information Is the user's foot on the paper and on the paper.

Therefore, after the measurement application is driven, the user who activates the shooting function matches each corner of the reference frame displayed on the screen of the user terminal 100 with each corner of the paper, and touches the shooting button image displayed on the screen. And the user's foot placed on the paper must be photographed, and by matching the user's heel to any one of the edges of the paper before shooting, the position of the heel covered by the lower part of the user's leg may be displayed indirectly in the photo information. To make.

Additionally, for accurate foot length and width measurement, the user's foot is preferably disposed to form an angle of 90 ° with respect to any one of the edges of the paper that matches the heel, so that the paper and the user's foot are clearly distinguished. It is desirable to generate photo information in the state of removing the socks, but in the case of inevitably generating photo information in the state of wearing the socks, the color of the paper and the color of the socks are different so that the paper and the user's feet can be clearly distinguished. good.

In addition, the photographing unit 120 is configured to automatically generate photo information when paper matches the reference frame.

That is, a user who wants to photograph his feet on the paper while holding the user terminal 100 can hold the user terminal 100 with both hands to maintain a horizontal balance, but the user terminal 100 In the process of touching the photographing button provided on the main body or displayed on the screen, a problem may occur in which the horizontal balance is unbalanced, so the photographing unit 120 matches the paper to the reference frame, but the matching time is a preset time. If so, this problem is solved by automatically generating photo information.

In addition, for the same reason as above, the foot size-based shoe size calculation system includes a voice recognition unit 121 for recognizing a user's voice as shown in FIG. 2, and the voice recognition unit 121 includes a user's voice. When it is recognized, the photographing unit 120 is configured to automatically generate photo information by driving the camera.

Known speech recognition technology is applied to the speech recognition of the user by the speech recognition unit 121.

 At this time, the voice of the user recognized by the voice recognition unit 121 may be words such as "shoot" or "start", the user can register his voice, use the preset word as it is, or use a new word Can be specified, and not necessarily one word.

In addition, as shown in FIG. 1, the user terminal 100 calculates the length of the user's foot based on the vertical length of the reference frame to generate length information, and calculates the user's foot width based on the horizontal length. Characterized in that it comprises a calculation unit 130 for generating the width information.

The calculating unit 130 calculates the user's foot width based on the horizontal length of the paper in which the horizontal and vertical lengths are known or measured by the user, and calculates the user's foot length based on the vertical length of the paper. As one component of the present invention, the calculated user's foot length and foot width are utilized for the purpose of deriving the correct shoe size to fit the user's foot.

That is, the size of the commonly used A4 paper has a horizontal length of 210 mm and a vertical length of 297 mm, so if the ratio of the user's foot length to the vertical length of the paper shown in the photo information is 1: 0.87, 1: 0.87 = 297: By applying the formula of X, the user's exact foot length can be calculated, and the above method may also be applied to the method of calculating the user's foot width, but it is not necessarily limited to this method.

More specifically, as shown in FIG. 4, the calculation unit 130 is displayed on the screen of the user terminal 100, and a horizontal line that generates a first horizontal line and a second horizontal line movable along a length direction of the screen It is characterized in that it comprises a length calculation unit 132 for generating length information by calculating the distance between the generation unit 131 and the first horizontal line and the second horizontal line.

The first horizontal line and the second horizontal line are straight lines that are horizontally displayed on the screen of the user terminal 100, respectively, and the position can be moved by the user's manipulation, so that one is positioned to match the edge of the paper indicated in the photo information. , The other is positioned to match the front end of the user's foot shown in the photo information, which is an accurate criterion for calculating the ratio of the user's foot to the length of the paper, and as a result, the user's foot length can be measured. To make.

That is, as described above, before generating the photo information, the user's heel is positioned to coincide with the edge of the paper, so if any one of the first and second horizontal lines coincides with the edge of the paper, the user's leg The effect that the position of the heel in the state obscured by the lower portion can be accurately displayed occurs, and the length calculation unit 132 calculates the ratio of the user's foot length to the vertical length of the paper. And calculating the distance between the second horizontal lines, resulting in the user's foot length being measured.

The user's foot length measured in this way is provided to the user so that it can be used for purchasing shoes, but the user's foot length can be variously composed of 236mm, 242mm and 273mm, whereas the general shoe size is 235mm, Since it is limitedly provided at intervals of 5 mm, such as 240 mm and 270 mm, a user having a foot length of a specific length, such as 272.5 mm, may be confused in selecting a shoe size.

Therefore, in order to solve this problem, the user terminal 100 is characterized by comprising a recommendation unit for recommending a shoe size suitable for the user based on the measured user's foot length, the recommendation unit is the user's foot We recommend the shoe size closest to the length, but be sure to consider the user's foot width.

In addition, as shown in FIG. 4, the calculation unit 130 is displayed on the screen of the user terminal 100, and a vertical line generation unit generating first vertical lines and second vertical lines movable along the width direction of the screen It characterized in that it comprises a (133) and the width calculation unit 134 for calculating the distance between the first vertical line and the second vertical line to generate width information.

Each of the first vertical line and the second vertical line is a straight line displayed vertically on the screen of the user terminal 100, so that the position can be moved by the user's manipulation, so that any one of them corresponds to the right end of the foot shown in the photo information. And the other is positioned to match the left end of the user's foot shown in the photo information, which is an accurate criterion for calculating the ratio of the user's foot width to the width of the paper, and consequently, by the width calculating unit 134 Allow the user's foot width to be measured.

That is, the width calculating unit 134 may calculate a distance between the first horizontal line and the second horizontal line by calculating a ratio of the user's foot width to the horizontal length of the paper, and consequently, the user's foot width The measured effect occurs.

The user's foot width must be considered in addition to the user's foot length, which is the most important criterion in selecting the shoe size, but generally, the standard for selecting the shoe size according to the foot length and foot width is not clearly presented. Since the recommendation unit is configured to consider not only the user's foot length but also the foot width in recommending the shoe size to the user.

In various embodiments of the present invention, if the user's foot length is 272mm, the recommender may initially select 270mm as an appropriate shoe size, but when the user's foot width is greater than or equal to the reference value, the final recommendation may be made to 275mm.

In addition, when the user's foot length is 273mm, the recommender may initially select 275mm as an appropriate shoe size, but when the user's foot width is greater than or equal to a reference value, the final recommendation may be made to 280mm.

In addition, when the user's foot length is 272.5mm, the recommendation unit may initially select 270mm and 275mm, but may select and recommend 270mm or 275mm according to the user's foot width.

At this time, the reference value refers to the average value of the foot widths of a plurality of users having the same foot length, and as the number of users to be measured increases, it is desirable to update and update it periodically.

In addition, the foot size-based shoe size calculation system according to the present invention may be configured to measure the user's foot thickness and provide it to the user, and be utilized to recommend the shoe size by the recommendation unit, and the method for measuring the foot thickness It is possible to follow the same or a similar method of measuring the foot length and foot width of, and accordingly, it is also possible to obtain the user's foot circumference length.

Thereafter, as shown in FIG. 5 (b), the user matches his heel to the edge of the A4 paper while simultaneously aligning the length direction of the paper and the length direction of the foot, and each side of the reference frame and the angle of the paper. After the sides are matched as much as possible, photographing can be performed. Accordingly, the horizontal line generation unit 131 generates a first horizontal line and a second horizontal line, and the vertical line generation unit 133 generates a first vertical line and a second vertical line, , It is displayed on the screen of the user terminal 100 as shown in Figure 5 (c).

Thereafter, as shown in FIG. 5 (d), the user can move the first horizontal line and the second horizontal line to match the edges of the paper and the front end of the foot, respectively, and move the first vertical line and the second vertical line, respectively. It can be made to match the left end of the foot and the right end of the foot. Accordingly, the length calculation unit 132 and the width calculation unit 134 calculate the user's foot length and foot width, respectively.
