Coating evaluation device and coating evaluation method

A coating evaluation device comprising:

• a surface roughness acquisition unit configured to acquire surface roughness information representing a surface roughness of a coating surface;
• a material acquisition unit configured to acquire material information representing at least one of a type of material constituting the coating surface, a coating thickness of the coating surface, and an amount, shape, or orientation of a lustrous material included in a coating of the coating surface;
• and
• a controller configured to
• estimate an evaluation value that corresponds to a combination of the surface roughness information and the material information by using an evaluation model that outputs a brilliance evaluation value pertaining to the coating surface in response to an input including the surface roughness information and the material information.

A coating evaluation method comprising:

• acquiring shape information representing a curved shape of a coating surface;
• acquiring surface roughness information representing a surface roughness of the coating surface;
• and
• estimating an evaluation value that corresponds to a combination of the shape information and the surface roughness information by using an evaluation model that outputs a brilliance evaluation value pertaining to the coating surface in response to an input including the shape information and the surface roughness information.
