POSITIONING APPARATUS, POSITIONING METHOD, POSITIONING PROGRAM AND CUTTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To perform efficient positioning while preventing reduction in accuracy when adjusting the position of a pattern, which is caused by blur and position variation of pattern images. Ž

SOLUTION: The positioning apparatus includes: a reference pattern setting means 11 for setting the reference pattern of a plurality of patterns P forming a pattern groupGr; a pattern image capturing means 12 for acquiring the image data of the pattern P by imaging the pattern P; an error acquisition means 13 for acquiring an error for each pattern by comparing the image data of the pattern P with the reference pattern; a positioning pattern specifying means 14 for specifying at least one valid pattern P+or invalid pattern P-from the plurality of patterns P on the basis of the error; and a position information calculation means 15 for calculating position information or position adjustment information relating to the pattern group PGron the basis of at least one valid pattern P+or invalid pattern P-.
