1. A coating evaluation device comprising:
a shape acquisition unit configured to acquire shape information representing a curved shape of a coating surface;
a surface roughness acquisition unit configured to acquire surface roughness information representing a surface roughness of the coating surface; and
a controller configured to
estimate 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.
