Abstract

PURPOSE:To decrease the number of times of teachings by designating the range of the change of the inclination and the size of a pattern, teaching a reference pattern, generating automatically all pattern fluctuations on a system side and obtaining the data of the feature quantity of the pattern, etc. CONSTITUTION:The inclination change and the size change of a character are inputted and this value is, for example, the inclination change of -5 deg.-5 deg. and the size change of 0.7-1.3-fold. The pattern of the character whose inclination is 0 deg. and whose size is standard (the reference pattern) in a first category is fetched as a binary picture from a camera. With one teaching operation, a system side turns the inputted character pattern of A by, for example, 1 deg. and obtains the feature quantity data of the pattern at each angle. By turning, enlarging and reducing this, a combination teaching that the inclination changes are eleven times from -5 deg.-5 deg. and the size changes of 0.7-1.3-fold are seven times by 0.1-fold can be attained. Thus, a pretty correct feature quantity distribution can be obtained with one teaching operation and a recognition ratio can be improved.
