1 and 4, the image recognition system 160 includes an image storage unit 165, an image comparison unit 170, a network means 175, and a controller 180.

The image storage unit 165 is a general-purpose storage device such as a hard disk, a RAM, or an optical disk device. The image storage unit 165 stores image data in which the digital camera 115 photographs a measuring operation of the sit-up of the measurer. In addition, the image storage unit 165 stores standard motion data composed of reference image data in which the position of the measurement mat 125 has been previously photographed through the digital camera 115 and standard posture data at the time of sit-up measurement. The unit 170 allows the data to be compared. In addition, the image storage unit 165 stores image information about the precautions for the use of the sit-up measuring apparatus 100, a method of using the measuring instrument, and the like, so that the information can be output to the measurer through the display 150. .

The image comparison unit 170 compares the image data photographed and input by the digital camera 115 with the standard motion data of the sit-ups stored in the image storage unit 165 to evaluate the measurement posture of the measurer, and the number of sit-ups. Calculate At this time, the method of comparing the data is a conventional image comparison method, extracting the intensity (luminance) value for the boundary of the image from the image data of the posture of the measuring person by the grid method (gird method), The difference data is generated by comparing the values with the contrast values of the standard attitude data. That is, it is determined whether or not the measurer's posture is appropriate by calculating whether the difference data falls within a preset error range. In the same way, when the measurer moves to the reference position, the measurer compares the contrast value of the corresponding image images with the contrast value of the reference image data, and uses the distance value for the preset unit pixel to measure the knee support rod ( It is determined whether or not it has moved adjacent to the reference line perpendicular to 135) to count the number of sit-ups. For example, the boundary at which the x coordinate pixel value of the boundary value at which the knee support rod 135 of the measurement mat 125 is located on the reference image data is 100 and the head of the measurer is positioned on the image data captured by the digital camera 115. If the x-coordinate pixel value of the value is 140, the pixel difference is 40, the actual screen width is 100 cm, and the resolution of the image data is 480 x 640, the actual distance between the two boundary values is about 8 cm. At this time, if the error range for the distance that the head of the measurer should be close from the knee support bar 135 is 10 cm or less, the value is included in the error range, so that the number of sit-ups is normally counted.

The network means 175 is a wired modem device, which transmits personal information stored in the memory key 140 to the management server (not shown) together with the number of sit-up measurements calculated by the image comparing unit 170. do. In this case, the measuring instrument main body 200 may be directly connected to the management server using the network means 175, or may be connected to a management server located at a remote location through a wired / wireless communication network such as a public telephone network, the Internet, a mobile communication network, a wired / wireless dedicated network, and the like. have.

In the present embodiment, the network means 175 is described as a wired modem device that is connected to a server system or an external communication network in a wired manner. However, the network means 175 may use a wireless communication device that is connected using a wireless communication such as Bluetooth or a mobile communication network. In addition, the memory key 140 has been described as a mobile storage device using a contact method, but may use a mobile storage device using a non-contact method such as radio frequency (RF) or infrared communication.
