Print inspection device, print inspection method, and program

A print inspection method that inspects a character printed on an inspection target, the print inspection method comprising:

• a capturing step that captures a region of the inspection target including a portion on which the character is printed;
• a shape matching processing step that executes a shape matching process to check a shape of a captured character pattern included in a captured image obtained in the capturing step against a shape of a preset reference character pattern while changing a deformation degree of the shape of the reference character pattern and to search for a matched character in which a similarity of the shape of the captured character pattern to the shape of the reference character pattern is greater than or equal to a threshold value;
• a deformation pattern generating step that generates a deformed character pattern, the deformed character pattern being obtained by deforming the reference character pattern at a deformation degree to which the character is matched in the shape matching process;
• and
• an inspection processing step that inspects whether a printed state of the character is satisfactory from a result of comparison between the deformed character pattern and the captured character pattern.

A non-transitory computer readable medium storing a program executed by a computer that executes a character inspection process that inspects a character included in a target image, the program comprising:

• causing the computer to execute:
• a shape matching processing step that executes a shape matching process to check a shape of a captured character pattern included in the target image against a shape of a preset reference character pattern while changing a deformation degree of the shape of the reference character pattern and to calculate a similarity of the shape of the captured character pattern to the shape of the reference character pattern;
• a deformation pattern generating step that generates a deformed character pattern, the deformed character pattern being obtained by deforming the reference character pattern at a deformation degree to which the similarity is greater than or equal to a threshold value;
• and
• an inspection processing step that inspects whether a printed state of the character is satisfactory from a result of comparison between the deformed character pattern and the captured character pattern.
