1 is a block diagram of a personalized insole manufacturing apparatus based on static and dynamic information according to an embodiment of the present invention. Referring to FIG. 1, a personalized insole manufacturing apparatus 1000 based on static and dynamic information includes a foot depth image obtaining unit 1100, a foot characteristic information generating unit 1200, and an insole model generating unit 1300.

2 is an embodiment of an apparatus 1000 for manufacturing a personalized insole based on static and dynamic information in an embodiment of the present invention.

The foot depth image obtaining unit 1100 may obtain a foot depth image of the foot 100 of the measurement subject located on the foot plate 200. The foot depth image can be photographed using the camera 1110, as shown in FIG. For example, toward the foot surface of the foot 100 of the person to be measured located on the foot plate 200. The foot plate 200 may be a transparent material or an opaque material.

The camera 1110 may also be a depth and color (RGBD) camera, or a depth camera, but is not limited thereto. In the following, the calculation of the arch parameters based on the foot depth image obtained by using the depth and color camera will be described as an example.

The foot depth image obtaining unit 1100 can pre-process the obtained foot depth image. For example, the foot depth image obtaining unit 100 may filter the noise of the foot depth image. After filtering, the foot-depth image obtaining unit 100 may convert each pixel into a three-dimensional point cloud. Then, each pixel of the color image is associated with each pixel of the depth image to generate three-dimensional point cloud color information.

Figures 3A-B illustrate various forms of foot depth images in one embodiment. FIG. 3A shows a filtered depth-of-field image, and FIG. 3B shows a foot-depth image in depth-color form.

The foot characteristic information generating unit 1200 can extract foot depth information from the foot contacting surface and the sole foot from the foot depth image.

First, the foot characteristic information generating unit 1200 can detect the sole contact surface information of the to-be-measured person in contact with the foot plate from the foot depth image. The foot characteristic information generation unit 1200 can detect the sole contact point information of the measurement subject in contact with the foot plate from the foot depth image. In this case, the foot characteristic information generating unit 1200 can generate foot surface contact information based on the sole contact point information and the foot depth image.

The foot characteristic information generation unit 1200 generates the foot characteristic information 1200 based on the distance A from the camera 1110 to the foot plate 200 and the distance B from the foot plate 200 to each pixel of the foot depth image, Can be detected. For example, pixels having a difference between distances B and A for each pixel within a predetermined range may be determined as contact points. The contact surface may be detected using this contact point. Through this process, the foot characteristic information generation unit 1200 can obtain the depth of the sole contact surface and the sole from the foot depth image.

The foot characteristic information is arbitrary information related to the sole, and may include any information about the shape and overall shape of each part of the sole. For example, the foot characteristic information may include static information obtained in a static state or dynamic information obtained in a dynamic state.

In one embodiment, the foot characteristic information includes foot shape, foot width, foot arch position, foot arch width, MLA (medial longitudinal arch), LLA (lateral arch), and TCA And a transverse component of a transverse component of the arch).

As described above, the foot characteristic information generating unit 1200 can generate foot characteristic information in a static or dynamic state, and the foot characteristic information generating unit 1200 can generate static foot characteristic information in a static or dynamic Foot characteristic information or dynamic foot characteristic information, respectively.

In one example, the foot characteristic information generation unit 1200 can generate the static foot feature information from the foot depth image obtained while the measurement subject is in the fixed specific posture. In this case, the static foot characteristic information includes at least one of foot shape, foot width, foot arch position, foot arch width, MLA (medial longitudinal arch), LLA (lateral arch) And a transverse component of the arch (arch component of the foot arch). Here, the fixed specific posture includes a posture in which the measurement subject bends the knee at a predetermined angle (for example, 90 degrees) or a posture in which the knee is extended, but the present invention is not limited thereto.

Also, in one example, the foot characteristic information generating unit 1200 can generate the dynamic foot feature information from the foot depth image obtained while the to-be-measured person moves the foot. In this case, the dynamic foot characteristic information includes at least one of foot shape, foot width, foot arch position, foot arch width, MLA (medial longitudinal arch), LLA (lateral arch) And at least one or at least one variation of the transverse component of arch (TCA) of the arch. The dynamic foot characteristic information may be generated from the foot depth image acquired while the subject is walking, running, climbing stairs, lifting one leg, sitting in position, and so on.

In the foot characteristic information, the sole shape represents the shape of the entire foot floor as shown in Fig. 3A or Fig. 3B. The width of the sole is the area of the area surrounded by the circumference of the upper sole.

FIGS. 4A to 4C show plantar images for explaining MLA, LLA, and TCA, respectively, according to an embodiment of the present invention.

4A shows the MLA 21. The MLA 21 is a geodesic curve connecting the heel 11 and the first metatarsal joint 12. Here, the first metatarsal joint may be the metatarsal joint of the thumb or index toe in the case of the right foot.

4B shows the LLA 22. The LLA 22 is a geodesic curve connecting the heel 11 and the second metatarsal joint 13. Where the second metatarsal joint may be a stop or metatarsal joint of the medial toe.

4C shows the TCA 23. The TCA 23 is a geodesic curve 23 connecting the highest point 21a of the MLA 21 and the highest point 22a of the LLA 22.

Figure 5 is a side view of the foot skeleton labeled MLA, LLA and TCA. Referring to FIG. 5, the MLA 21, the LLA 22, and the TCA 23 appear for the foot skeleton 110.

According to one embodiment of the present invention, by using MLA, LLA, and TCA as foot characteristic information, it is possible to expect an improvement in foot comfort and exercise performance through dispersion of pressure applied to the sole. In addition, MLA, LLA, and TCA can be used to develop personalized insole that takes into consideration the characteristics of each arch, because the roles of both MLA, LLA, and TCA are different in movement such as walking and running. In addition, there is an advantage that the foot can be assisted more precisely by considering the change of the arch under the condition where the load is applied and the condition where the load is not applied.

In foot characteristic information, the position of the foot arch can be determined based on the position of the highest point of the foot arch. For example, depending on the position of the peak of the arch arch, it may be divided into full, middle, and tribe.

6A and 6B are views for explaining the height and width of a foot arch and their changes in an embodiment of the present invention. 6A is a side view of the foot 100, and FIG. 6B is a bottom view of the foot 10 of the foot 100. As shown in FIG.

6A and 6B, the height H, the length L and the width W of the arch are changed in a state in which the user is not putting on weight (state A) and a state where the user is wearing the weight (state B). In FIGS. 6A and 6B, the cases where the body weight is not loaded (state A) and the case where the body weight has not been loaded (state B) have been described for the sake of simplicity. In Fig. 6A, H1 and H2 represent the height from the bottom of the sole to the highest point of the arch. Here, the weighted state may include standing or standing on one leg.

In one embodiment, the foot characteristic information may further include a flexibility parameter. The flexibility parameter can be determined on the basis of changes in the width or height of the foot arch in the absence and weight of the soles.

For example, the flexibility parameter may be determined based on Equations 1 and 2 below with reference to FIG. 6A or 6B.

[Equation 1]

The height-related flexibility parameter of the arch = (H1-H2) / (H1)

&Quot; (2) "

The width-related flexibility parameter of the arch = (W1-W2) / (W1)
