Abstract
The present invention is aimed at detecting an operator's height and position of each body part with a certain range of accuracy, which is used for calculation of a BMI value or operation of a game. An exercise assist device (101) is provided with a horizontal bar (102), a bar support (103) to support the bar, and a floor mat (104) on a surface of its body. A video camera (201) is mounted on the top of a monitor (701) as illustrated, for example, in FIG. 7 and captures the operator as well as the horizontal bar (102) and bar support (103) in one image. Since the horizontal bar (102) and bar support (103) together with the operator are captured in one image, they become a three-dimensional measurement reference, so that the operator's height can be calculated from the captured image.
Claims7
An image recognition device comprising:
- an imaging means for capturing an object to be measured on a floor mat and a three-dimensional reference in one image;
- a three-dimensional measurement reference provided on the floor mat so that it is within a predetermined range from the object to be measured and including more than or equal to four points placed at predetermined positions relative to the imaging means;
- and
- an image 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.
A method to recognize an image of an object to be measured on a floor mat having a three-dimensional measurement reference, the three-dimensional measurement reference being placed under the object to be measured and on the floor mat so that it is within a predetermined range from the object to be measured and including more than or equal to four predetermined points relative to the imaging means, the method comprising the steps of:
- imaging to capture the object to be measured on the floor mat and the three-dimensional measurement reference in one image;
- and
- calculating an image position to extract an image corresponding to the object to be measured and the three-dimensional measurement reference from the captured image and to calculate 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.
