METHOD FOR RECOGNIZING PATTERN, METHOD FOR GENERATING TEACHING DATA TO BE USED FOR THE METHOD AND PATTERN RECOGNITION APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a pattern recognition method for generating defective data and compensating shortage to improve a recognition ratio and a teaching data generating method to be used for the pattern recognition method. PSOLUTION: An appearance inspection apparatus for performing learning on the basis of many teaching data stored in a teaching file, recognizing a pattern and judging a defect is provided with a teaching data generation device 40 for generating new teaching data by deforming one data, the teaching data generation device 40 generates new teaching data by deforming specific teaching data which has the small number of data out of many teaching data stored in the teaching file 35, replenishes the generated teaching data to the teaching file to recognize defects in the teaching data. When teaching data to be generated are image data, affine transformation including the enlargement, contraction and rotation of an image and attribute conversion including brightness, contrast and edge intensity are executed to generate new teaching data.
