DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footprint detecting and displaying device useful for determining the size and shape of shoes.

[0002]

2. Description of the Related Art Hitherto, a foot type detecting and displaying apparatus using an image scanner has been proposed for measuring a size such as a width and a length of a foot and a shape of the foot. An example is shown in FIG. In this figure, the subject puts the foot f on the transparent plate 100.
Is mounted, the sole of the foot is imaged by the monochromatic optical sensor 101, and the shape and size of the foot f are measured based on the imaged information. In such a conventional footprint detection display device, when light is emitted from a light source 102 provided below the transparent plate 100, the light passes through the transparent plate 100 and irradiates the sole fb. The reflected light from the sole fb enters the optical sensor 101, and a footprint is displayed on a display by a computer (not shown) based on the contrast of the incident reflected light.

[0003] Here, in order to select a shoe sufficiently matching the shape of the foot, not only the length of the foot, but also the degree of protrusion of the portion fc on the inner side surface of the foot, the presence or absence of beans and octopus formed on the foot, It is also important to understand the location. However, FIG.
As shown in (b), the site fc on the inner surface of the foot f such as the talus or scaphoid protruding inside the foot, that is, the arch f
Since the portion fc above a is a surface close to the vertical, the light L from the light source 102 is reflected upward, and is not sufficiently reflected toward the optical sensor 101 below. Shape cannot be detected. In addition, the presence or absence and shape of leg or octopus on the foot cannot be sufficiently grasped.

On the other hand, as shown in FIG. 6, light sources 102 and 1 on which light L enters the transparent plate 100 beside the transparent plate 100.
02 is proposed (see Japanese Utility Model Laid-Open No. 1-178006). In this prior art,
As shown in FIG. 6B, the light L travels by being totally reflected in the transparent plate 100, and at the same time, the refractive index changes at the portion where the sole fb and the transparent plate 100 are in contact with each other and diffusely reflected. . Therefore, since the contrast between the contact portion and the non-contact portion can be obtained, the shape of the contact portion of the sole can be grasped.

[0005]

However, the transparent plate 100
The protrusion fc on the side of the foot f not in contact with
Since the light L does not hit at all, the contour of the foot f cannot be known. In addition, a special scanner for totally reflecting light in the transparent plate 100 is required, so that the cost is significantly increased.

Accordingly, the present invention provides an inexpensive apparatus for detecting a foot type including an image scanner, which is capable of detecting a contour of a foot including a part protruding inside the foot in addition to a leg and an octopus. The purpose is to improve.

[0007]

In order to achieve the above object, a foot type detection display device according to the present invention comprises a transparent plate on which a foot is placed and a transparent plate as an upper plate. A digital image scanner of an object fixing type that irradiates light to the sole of the foot and makes reflected light from the foot incident on an optical sensor, and a computer that displays a footprint on a display based on an imaging signal from the image scanner Wherein the light sensor is a color light sensor and the display is a color display.

In the present invention, "scanning of light" is performed by moving a reflecting mirror or a light source itself. Fluorescent lamps and RGB3
A color LED (light emitting element) or the like can be used. As the “color optical sensor”, for example, a color CCD (imaging device) having a color filter can be used. The “object fixing method” means a method of capturing an image of an object by scanning light without moving the object. `` Foot type ''
The shape of the foot includes the portion protruding inside the foot.

Next, the measurement principle of the present invention will be briefly described. The footprint detection display device of the present invention detects the footprint by irradiating the foot with the scanning light while scanning the light, and causing the reflected light from the foot to enter a color optical sensor. Here, the leg beans and octopus are slightly different in color from the other parts. Therefore, by detecting the footprint based on the color difference, the presence or absence and the position of the beans and octopus can be accurately grasped.

In particular, in the present invention, footprints are detected using color information based on the contrast of each color, so that more measurement information is required as compared to detection based on only a single-color contrast. Therefore, even for the protruding part on the inside of the foot where reflected light is not sufficiently obtained, it is possible to distinguish the color foot part from the background of another color, so that the outline must be accurately detected and displayed. Can be.

In particular, on a transparent plate, apart from a scanning light source,
If a light source to be scanned that irradiates light on the inner surfaces of the left and right feet is provided, light is diffusely reflected on the inner surfaces of the feet and enters the optical sensor, so the inner contour of the feet that could not be grasped conventionally can be more improved. You can know more accurately.
