Classification: CPC G  B | IPC G

Claim 13:
14. An evaluation system configured to evaluate coverage of an evaluation target that has been subjected to a shot peening treatment with shot media by using a captured image of the evaluation target, the evaluation system comprising:
a data storage device that stores instructions; and
at least one processor configured to execute the instructions to perform a method including:
acquiring the captured image including a plurality of dent regions, each dent region of the plurality of dent regions is an image of a dent formed on the evaluation target by the shot media of the shot peening treatment, the captured image being image data including a plurality of pixels;
generating an evaluation image by correcting the captured image including:
extracting an evaluation region from the captured image based on an average size of the plurality of dent regions included in the captured image,
correcting a color of the extracted evaluation region by adjusting pixels of the extracted evaluation region based on a color of a reference region included in the captured image, the reference region is an image of a reference having a specific color, and
generating the evaluation image based on the corrected evaluation region, evaluating the coverage based on the evaluation image, the coverage is an index of a finishing degree of the shot peening treatment, and the coverage is a rate of the area of the dent regions with respect to the total surface area of the evaluation target; and

outputting an evaluation result of the coverage.
