Title: Character recognition method
Inventor: WATANABE TSUTOMU
IPC: G06T1/00
Filed: 1992-01-24
Abstract: PURPOSE:To improve the recognition rate by judging the test result as normal when the second or third character to be tested agrees with the reference character even though the first character to be tested does not agree with the reference character. CONSTITUTION:The recognition character number of a product 10 to be tested with the estimated number of the product are collated. The result of collation, that is, the coincidence and noncoincidence of the number is outputted to a host computer 3 and to a display device 4. In the case of noncoincidence, 'NG' is outputted. When the 'NG' section is inside the specified area, whether or not the former estimated number sent from the host computer 3 and the number in the specified character area of this estimated number coincidence is discriminated. If they coincide, the second and third characters recognized by a character recognition device 2 and the estimated number in the noncoincidence section of the character in the specified character area are collated. As a result, when the numbers coincide, the processing result is judged to be 'OK' and when they do not coincide, judged to be 'NG'.
