Abstract: A process for producing a total match metric for matching color and appearance of a target coating and at least a specimen coating is provided. The total match metric (TMM) are produced based on color difference values (ΔE) at three or more color viewing angles, sparkle difference values (ΔS) at one or more sparkle viewing angles and flop difference value (Δf) between the target coating and the specimen coating using one or more linear functions, one or more non-linear functions, or a combination thereof. The total match metric can be used in producing matching coatings that match color and appearance of the target coating. The total match metric can be particularly useful for repair coating damages to vehicles.

Abstract: A device for radiometrically gauging the surface of a measurement object (O) includes: at least one measurement array featuring an illumination array and a pick-up array; and a processor (P) for controlling the illumination array and the pick-up array and for processing measurement signals produced by the pick-up array and for providing processed image data. The illumination array exposes a region of the measurement object (O) to illumination light at an illumination angle (θi) and an illumination aperture angle (αi), and the pick-up array captures measurement light, reflected by the measurement object (O), at a pick-up angle (θv) and a pick-up aperture angle (αv) and guides it onto an image sensor exhibiting a pixel structure. The measurement object (O) is gauged multispectrally in multiple wavelength ranges, wherein the image sensor produces multispectral image data. Angular and spatial conditions are indicated which optimise the measurement device (MD) with regard to characterising sparkles.

Abstract: An illumination device is provided with a light source, a photodetector, and a support structure. The light source, which emits light, has light distribution in which a reference axis serves as an axis of symmetry or light distribution in which a plane including the reference axis serves as a plane of symmetry. A first light beam in the light is guided to the object to be illuminated. A second light beam in the light is guided to the photodetector. The photodetector detects intensity of the second light beam. The light source and the photodetector are supported by the support structure in positions and postures that allow the first light beam and the second light beam to be guided in an aforementioned manner. A traveling direction of the first light beam and a traveling direction of the second light beam make the same angle with the reference axis.
