Abstract (en)

[origin: WO2010066236A1] A calibration standard for an image processing system as an optical measuring device is described, which ensures high accuracy and the correct determination of brightness and/or tristimulus values for two-dimensional measurements. According to the invention, the calibration standard comprises at least four dimensional circles (4.1; 4.2; 4.3; 4.4) on a dimensionally stable planar surface (1).
