Classification: CPC G  B | IPC G

Claim 0:
1. 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,
expanding or contracting the extracted evaluation region by adjusting pixels of the extracted evaluation region so as to adjust the average size of the dent regions to a predetermined size, and
generating the evaluation image based on the expanded or contracted 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.
