Claim One:
1. An image recognition device comprising: a floor mat sensor for generating different signals depending on a position where a foot placed; a three-dimensional measurement reference that is provided above the floor mat sensor and has more than or equal to four points to limit movement of the foot in a predetermined area; an imaging means being placed at a predetermined position relative to the three-dimensional measurement reference, for capturing an object to be measured on the floor mat and three-dimensional measurement reference in one image; an object position calculation means for extracting an image corresponding to the object to be measured and the three-dimensional measurement reference from the captured image and calculates a position of the object to be measured on the basis of a position information of the three-dimensional measurement reference that is previously obtained and stored and a distortion information relating to distortion of the image of the three-dimensional measurement reference captured by the imaging means; and an operation determination means for receiving the signal generated by the floor mat sensor and determines a predetermined operation depending on a position of the foot detected within the predetermined area; and an adjustment means for using a distance reference placed on the floor mat at a predetermined distance from the imaging means to adjust the position calculated by the object position calculation means on the basis of a distance between the object to be measured and the imaging means.
