<P>PROBLEM TO BE SOLVED: To provide a method and a device for reading a formed body having a perforated group to which code information is attached. <P>SOLUTION: Digital image data including the predetermined region of a formed body are acquired, and the acquired digital image data are converted into perforating coordinate data showing the XY coordinates of each perforation by a digital image data converting part, and the deviation values of the perforating coordinate data from the grid-shaped intersection by a deviation value measuring part, and perforating deviation data are acquired, and the distribution density of perforating deviation data is generated by a distribution density measuring part, and a threshold is formed from the distribution density by a threshold calculation part, and a perforation at the perforating standard of the grid-shaped intersection and a perforation deviating from the perforating standard of the grid-shaped intersection are converted so as to be associated with binary data by a comparator arithmetic part from the perforating deviation data and the perforating coordinate data based on the threshold, and code information is generated and read from the binary data by a code information generating part. <P>COPYRIGHT: (C)2007,JPO&INPIT |
