Abstract

The invention refers to a system (38) for assessing the visual appearance of a reflective surface (50), comprising a visual output device (42), adapted to display at least one test image onto the reflective surface (50) and a visual capturing device (52), comprising an adjustable focal point position (54), wherein the adjustable focal point position (54) is tuneable to the reflective surface (50) as one capturing position (60) and to a complementary capturing position (62) that allows for clear capturing of the test image as a reflection (68) from the reflective surface (50); and wherein the visual capturing device (52) is adapted to capture at least one image in the one capturing position (60) and to capture at least one complementary image in the complementary capturing position (62). The system further comprises a data processing unit (76), comprising a database (78) and an evaluation algorithm (80), wherein the database (78) is equipped with data representing correlation between visual appearance of reflective reference surfaces and objective quality parameters and wherein the evaluation algorithm (80) is adapted to derive the objective quality parameters of the reflective surface (50) from the one image and from the complementary image and to compare the objective quality parameters with the data of the database (78) to assess visual appearance of the reflective surface (50). The invention further refers to a method of assessing the visual appearance of a reflective surface (50) of a vehicle, using the system (38).
