Abstract

A method for contactlessly establishing a temperature of a surface includes determining the temperature measurement values of the plurality of blind pixels and determining temperature measurement values of the plurality of measurement pixels. The method further includes determining a temperature measurement value and a temperature measurement values by subtracting the temperature measurement value of the first blind pixel of the plurality of blind pixels from a temperature measurement value of a second blind pixel of the plurality of blind. The method further includes correcting the temperature measurement values by pixel-associated temperature drift components in each case, wherein the temperature drift components are determined using the temperature measurement value and/or the temperature measurement value.
