ABSTRACT:
An apparatus capable of measuring a wet paint film thickness easily and accurately in a non-contacting manner. The apparatus includes a paint film surface data acquisition unit for obtaining paint film surface data indicating a roughness of a paint film surface in a wet state, in a non-contacting manner; a paint medium data input unit for inputting paint medium data specifying a paint medium from which a paint film is formed; and a paint film thickness calculation unit for calculating the paint film thickness from the paint film surface data and the paint medium data according to a dynamic levelling property of a wet paint film. The paint film surface data include wavelength data indicating a wavelength of an unevenness on the paint film surface, and roughness data indicating one of a peak to peak amplitude of the unevenness on the paint film surface, a surface roughness of the unevenness on the paint film surface, a power spectrum integrated value in an image of the paint film surface, and a density vector in the image of the paint film surface.
