摘要： Disclosed is a pattern matching method whereby a testing point can be searched accurately while simplifying the work of presetting. An image region of a part of a captured image is extracted, and a divided image of the image region is set as a template image. A pattern matching is performed by rotating the template image. Moreover, the pattern matching determines whether a point-symmetric pattern exists inside the image region.

摘要： There is provided an inspection apparatus and method that output an accurate matching position even if a search image contains a pattern similar to a template. An image search unit includes a relative position comparing unit which compares the relative position of a template in a template selection image with the relative position of a location currently being searched for in a search image and outputs the amount of position mismatch between the relative positions. A matching position determining unit determines a matching position by taking into consideration the amount of position mismatch in addition to search image similarity distribution information.

摘要： The present invention provides a unified template matching technique which allows an adequate matching position to be provided even in an image with a distorted pattern shape and a variation in edge intensity. A correlation value contribution rate map is created for the vicinity of each of top candidate positions obtained by applying a centroid distance filter to a normalized correlation map resulting from template matching. A corrected intensity image is created from the correlation value contribution rate maps. Luminance correction is performed based on the corrected intensity image. Local matching is performed again on the vicinity of each candidate position. The candidates are then re-sorted based on candidate positions and correlation values newly obtained. Thus, even in an image with a distorted pattern shape and a variation in edge intensity, an adequate matching position can be provided in a unified manner.
