A substantially flat mirror body that is arranged at an angle and reflects the light transmitted through the footrest plate in a predetermined direction, and the side of the footrest plate is substantially the same as the footrest plate.
One is placed at the same height position, and a mirror image of the side of the foot placed on the footrest plate and the mirror image of the bottom of the foot reflected on the mirror are taken into account.
At the same time, it is supported with the camera tilted downward by a specified angle so that it can be imaged together
An image pickup unit that is held and that simultaneously captures a mirror image of the side portion of the foot and the sole portion of the foot, and outputs image information that includes both the mirror image of the side portion of the foot and the sole portion of the foot, the footrest plate, the mirror body, and A support base integrally supporting the image pickup means and a measurement processing means for calculating the image information output from the image pickup means to derive the size of a predetermined portion of the foot are provided. As described above, in the present invention, the mirror body that reflects the bottom of the foot placed on the translucent footrest plate is arranged, the side of the foot is directly imaged, and the bottom of the foot is simultaneously taken as a mirror image. one image pickup means for imaging is one provided, obtained by capturing together the sides and bottom of the foot
By analyzing one image information and obtaining the foot size information, it is not necessary to position the image pickup means below the foot rest portion, and the information input system is limited to one image pickup means.
In addition, the foot can be imaged with a simple mechanism, which makes it possible to reduce the size and cost, and also includes the side and bottom mirror images of the foot.
Size information necessary and sufficient for shoe selection can be obtained from only one captured image with appropriate accuracy, measurement accuracy and cost / compactness can be compatible at a high level, and usability can be improved.
