Title: Pattern matching device
Inventor: ISHIHARA AKIRA
IPC: G06T7/00
Filed: 1989-11-06
Abstract: PURPOSE:To correctly search a prescribed pattern by applying the positional data of the succeeding evaluation area to an address generating means based upon the positional data of a similar pattern applied from a matching processing means and executing the matching processing of plural patterns similar to a reference image pattern in an objective image data. CONSTITUTION:Plural reference image patterns P1, P2 are previously set up, and when the 1st similar pattern matched with the 1st reference image pattern P1 is searched from the objective image data, a partial area having a prescribed positional relation with the patter P1 is searched to decide whether the 2nd similar pattern matched with the pattern P2 exists or not. Thereby, even if the 1st similar pattern is misrecognized, its error can be checked by the matching processing of the 2nd similar pattern. Consequently, the accuracy of the pattern matching can be improved.
