The present invention relates to a bottom scanner of a three-dimensional object, and a data processing method for manufacturing an insole using the same. A method of processing data to ergonomically manufacture shoe insoles.

In general, a scanner has a structure in which a CCD camera and a light source are installed under a flat glass plate on which documents or pictures are placed. Such a scanner scans a document or a picture by moving the CCD camera horizontally.

With the advances in the technology of the two-dimensional scanner as described above, a three-dimensional scanner for scanning a three-dimensional object using a laser has been developed. Such a three-dimensional scanner has recently been applied to various fields, one of which is to manufacture the shoe insole using a three-dimensional scanner.

Figure 1 shows the structure of a typical shoe. As shown in Figure 1, the outsole (3: outsole) that is in contact with the ground, the insole (2) attached to the surface of the outsole (3), and the foot connected to the outside of the insole (2) and the outsole (3) It consists of an outer shell (1) surrounding the whole. Outer shell (1) and insole (2) and the outsole (3) is made separately, and forms a shoe structure through a sewing process.

In particular, the insole 2 is a portion facing the sole of the person, and the pressure distribution applied to the sole of the pedestrian is determined according to the shape of the insole 2. Therefore, when walking, the insole 2 should have the function of causing the pressure applied to the sole to be distributed as a whole without being concentrated on a predetermined part of the sole, so that the pedestrian feels the fatigue of the foot as little as possible.

By the way, insoles of various shoes currently on the market are manufactured by dimensions according to Korean standard footsteps. However, because the footsteps of a person differ from person to person, it was difficult to purchase shoes with insoles that exactly matched their footsteps. Therefore, the variation in pressure distribution applied to the soles through the existing insoles was inevitably large. As a result, since pressure is concentrated only on a part of the sole, pedestrians often feel tired.

In order to solve this problem, it is necessary to specially manufacture the entire shoe including an insole suitable for one's foot, and special production requires excessive cost. Therefore, it is not practical for ordinary people to make special shoes that exactly match their footsteps.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a three-dimensional bottom scanner capable of obtaining insole fabrication data that exactly matches its own foot.

Another object of the present invention is to provide a data processing method for insole manufacturing that can minimize the deviation of the pressure distribution applied to the sole using the data obtained with the scanner described above.

In order to achieve the above object of the present invention, the scanner according to the present invention includes a main body frame. The transparent mounting table on which the three-dimensional object is placed on the upper surface of the main frame is installed. The projection mirror on which the bottom of the three-dimensional object is projected is disposed on the bottom of the main body frame that is the vertical lower portion of the transparent mounting table. A slider is connected to the projection mirror, and the slider is connected to the main frame so as to be horizontally movable. The slider is connected to the horizontal moving device and moved horizontally with the projection mirror. A pair of laser irradiators which irradiate a laser beam with a transparent mounting part obliquely from the lower part is attached to both sides of the slider beyond both sides of a transparent mounting stand. The bottom of the three-dimensional object is scanned by each laser beam and projected onto the projection mirror, and a camera for photographing the projected image is provided on one side of the upper surface of the main frame.

The data processing method for manufacturing the insole using the data obtained with the scanner having the above-described configuration consists of the following steps. First, build a standard insole database that corresponds to the shape of the various soles. The sole is then scanned with a scanner to obtain the sole shape data. Then, one standard insole shape is selected that is closest to the sole shape data among several standard insole databases. Then, the shape of the sole according to the data of the selected standard insole and the shape of the sole data are superimposed to obtain the primary shape of the insole shape. Then, the pressure distribution actually applied to the sole is measured, and the shape data of the primary deformed insole is corrected according to the pressure distribution data, so as to obtain the shape data of the secondary deformed insole.                     

According to the configuration of the present invention described above, by scanning the bottom of a three-dimensional object having a curved shape such as the sole with a laser beam and photographing it with a camera, it is possible to accurately obtain data about the bottom of the three-dimensional object in three dimensions. In addition, since the data of the insole according to the actual pressure distribution can be obtained using the obtained data, it is possible to manufacture the insole that the pedestrian can feel the most comfortable.

Hereinafter, a bottom scanner of a three-dimensional object and a data processing method for manufacturing insole using the same according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

Figure 2 is a perspective view showing the appearance of the scanner according to the invention, Figure 3 is a perspective view showing the internal structure of the scanner by removing the exterior from the scanner of Figure 2, Figure 4 clearly shows the arrangement relationship of each component 5 is a plan view of a scanner, and FIG. 5 is a flowchart sequentially showing a data processing method for manufacturing an insole using a scanner according to the present invention.

First, as shown in FIG. 2, the scanner is connected to a computer 90 that processes data of the scanned stereoscopic object. Such a scanner has a sheath 10 in which either side portion protrudes in a substantially triangular shape. A rectangular opening is formed in the upper surface of the sheath 10, the longitudinal direction of the opening coincides with the direction of the protrusion of the sheath 10. A mounting table 30 made of a transparent material such as glass on which a three-dimensional object such as a person's sole is placed is provided in the opening. Therefore, the longitudinal direction of the transparent mounting table 30 also coincides with the direction of the protrusion of the sheath 10.

3 and 4 show the internal structure of the scanner with the sheath 10 removed. 3 and 4, the scanner includes a body frame 20 having a rectangular frame structure. The transparent mounting table 30 is installed at the center of the upper surface of the main frame 20. The projection mirror 40 seen through the transparent mounting table 30 is disposed in the vertical lower portion of the transparent mounting table 30. That is, the sole mounted on the transparent mounting table 30 is projected on the projection mirror 40. On the other hand, the guide rail 21 is provided in the center of the bottom face of the main body frame 20 along the longitudinal direction of the transparent mounting base 30. The central bottom portion of the projection mirror 40 is movably connected to the guide rail 21.

The slider 60 which is horizontally moved along the longitudinal direction of the transparent mounting table 30 is connected to the projection mirror 40. The slider 60 is arranged in the direction orthogonal to the moving direction of the projection mirror 40. In particular, the slider 60 has a length longer than the width of the transparent mounting table 30 so that both sides of the slider 60 protrude through both sides from the transparent mounting table 30 and the projection mirror 40.

A horizontal moving device for horizontally moving the slider 60 is connected to one end of the slider 60. The horizontal moving device includes a motor 50 mounted on one front side of the main body frame 20. Here, the front surface refers to the protruding direction of the exterior 10. The motor 50 has an axis that runs vertically downward. One end of the belt 51, which is operated in a caterpillar manner by the motor 50, is connected to the shaft of the motor 50. The other end of the belt 51 is rotatably supported by a pulley 52 provided on the rear surface of the main body frame 20 on the opposite side of the motor 50. The slider 60 is connected to the belt 51 and moves together in the moving direction of the belt 51. Of course, the projection mirror 40 also moves with the slider 60.

A pair of laser irradiators 70 and 71 for irradiating a laser beam toward the bottom of the sole placed on the transparent mounting table 30 is provided at both sides of the slider 60. Each laser irradiator 70, 71 is provided at both ends of the slider 60 so that the shape of the sole projected onto the projection mirror 40 does not interfere with the laser irradiators 70, 71. In particular, each laser irradiator 70, 71 forms a predetermined acute angle with the surface of the projection mirror 40 so that the laser beam can be irradiated to the underside of the transparent mounting table 30. That is, each of the laser irradiators 70 and 71 is disposed to be inclined at a predetermined acute angle toward the center of the projection mirror 40 while facing upward.

Thus, the image projected onto the projection mirror 40 is the image of the sole scanned with the laser beam. A camera 80 for capturing such projected images is installed on the front surface of the main body frame 20. Since the camera 80 needs to photograph the projection mirror 40, the camera 80 is disposed to be inclined downward toward the upper front outer side of the main frame 20 to face the projection mirror 40. The reason why the protrusion of the exterior 10 is needed is to secure an arrangement space of the camera 80.

The computer 90 described above is connected to the camera 80 so that the data processing program input to the computer 90 processes the image data captured by the camera 80, thereby displaying the soles on the monitor in a three-dimensional shape. do.

The scanner having the configuration described above has been exemplified for the purpose of scanning the sole for manufacturing the insole in this embodiment. However, the scanner of the present invention is not necessarily limited to the sole scanning application, but can be applied to all three-dimensional objects having a curved shape.

However, since the scanner of the present invention was invented for manufacturing insoles of shoes, a method of processing data for insole manufacturing using the scanner of the present invention will be described in detail with reference to FIG. 5.

As shown in Fig. 5, in step ST1, a database of standard insoles having various shapes is constructed. The standard insole database refers to data obtained by scanning the actual insoles employed in shoes of various dimensions with the scanner according to the present invention. The standard insole shapes displayed on the monitor through the data of these standard insoles do not have a shape corresponding to each person's sole shape.

Under these conditions, as in step ST2, the actual foot is scanned using the scanner of the present invention described above to obtain three-dimensional shape data.

This will be described in more detail as follows. The sole is placed on the transparent mounting table 30 to drive the motor 50. Then, by the movement of the belt 51, the slider 60, the projection mirror 40, and the laser irradiator 70, 71 move together. During this movement operation, the laser beam is irradiated from the laser irradiators 70 and 71 onto the underside of the transparent mounting table 30.

The sole image irradiated with the laser is projected onto the projection mirror 40 as it is, and the camera 80 photographs the projected image. The three-dimensional image captured by the camera 80 is transmitted to the computer 90, and the three-dimensional shape of the sole is displayed on the monitor as it is.

Then, in step ST3, a standard insole shape having a shape closest to the obtained sole shape data is selected. This selection is done automatically by a program that compares the sole shape data with the standard insole shape data, so that the optimal standard insole shape is selected.

If the standard insole shape is selected as above, in step ST4, the sole shape is superimposed on the selected standard insole shape. In other words, this overlapping operation can not be used as insoles by processing the actual sole shape into the insole shape, while the standard insole shape is different from the sole shape of each individual. will be.

As an example, if the heel is more protruding below the average person, the standard insole will be much more pressured on the heel than the average person when walking. However, through the overlapping operation as described above, the heel portion of the standard insole shape is deformed further down by the actual sole shape. Therefore, when walking, the pressure on the heel will be much reduced.

By the overlapping operation as described above, shape data of the insole that is primarily deformed in step ST5 is obtained.

The insole data that has passed the steps up to this point may be input to the machine tool, and the machine tool may process the insole according to the input data. Since the insole is manufactured under the optimum conditions corresponding to the sole shape of each individual, the comfort of the pedestrian wearing the insole manufactured by the method according to the present invention can be greatly improved than the conventional insole.

However, in the present invention, the following steps may be further performed.

5, the pressure distribution applied to the sole is measured as in step ST6. The reason for actually measuring the pressure distribution applied to the sole is that even though people with almost the same sole shape have different walking habits than humans, the pressure applied to each part of the sole is different. For example, some people have almost the same sole shape, but some people have a habit of walking with power in front of the sole, while others have the opposite habit.

In consideration of this point, after the sole pressure distribution is measured, as in step ST7, the operation of correcting the shape of the primary deformed insole is performed according to the pressure distribution data. When this correction operation is completed, the shape data of the secondary deformed insole is obtained as in step ST8.

When the step ST9 of inputting the shape data of the secondary deformed insole to the machine tool is performed, the machine tool processes the insole having an optimal shape for each individual according to the input data.

As described above, according to the present invention, since it is possible to accurately scan the bottom of a three-dimensional object having a curved shape such as the sole of the foot, the accurate data obtained through such scanning can be actively utilized for various purposes.

In particular, when used for insole manufacturing, it is possible to manufacture an insole having an optimal shape for each individual, it is possible to reduce the fatigue that pedestrians feel.

In the above, the bottom scanner of the three-dimensional object according to a preferred embodiment of the present invention and a data processing method for manufacturing an insole using the same have been described and illustrated, but the present invention is not limited to the above-described embodiment and is claimed in the following claims. Without departing from the gist of the present invention, it will be understood by those skilled in the art that various changes may be made.
