Template matching processing device and template matching processing program

摘要

The present invention is a template matching processing device capable of evaluating a similarity degree which supports even a case of intensive morphological change between a design image and a photographic image. In the template matching processing device, matching processing between the design image and the photographic image is performed, a partial design image is obtained by clipping a portion having the highest correlation (step 101), and processing for deforming the photographic image in accordance with the clipped design image (steps 102 to 105) is performed, so that correlation between the deformed image obtained and the design image is taken to be set as the similarity degree.

主权项

1. A template matching processing device for comparing an input image with a template, comprising:
a matching unit for obtaining a positional correspondence relation between a design image for matching generated from a design data for manufacturing a desired product and a photographic image obtained by taking a photograph of the product manufactured based on the design data, which is taken by a predetermined photographing device; and a similarity-degree evaluating unit, by referring to a design image for similarity degree evaluation generated from the design data and based on the positional correspondence relation defined by the matching unit, for generating a cumulative histogram of the photographic image or an image obtained by applying a predetermined processing to the photographic image at a corresponding position of a morphology evaluation portion on the design image for similarity degree evaluation and generating a cumulative histogram of the photographic image or an image obtained by applying a predetermined processing to the photographic image at a corresponding position of an out-of-morphology evaluation portion on the design image for similarity degree evaluation, and for evaluating a desired similarity degree between the photographic image and the design image for similarity degree evaluation by referring to both of the histograms.
