Abstract:
1. Thermal imaging camera ( 1 ) with an IR sensor arrangement ( 2 ), an output unit for the processed sensor data and an interchangeable IR lens ( 5 ), characterized in that the interchangeable IR lens ( 5 ) features distortion, in that an image processing unit ( 12 ) is constructed and this image processing unit ( 12 ) is designed to extract at least one feature from at least one IR image ( 6 ) recorded with IR sensor arrangement ( 2 ), wherein the one or more features are influenced by the distortion of interchangeable IR lens ( 5 ), and in that a data processing unit ( 13 ) is constructed and designed to derive a numerical value ( 14 ) that is determined by the distortion of interchangeable IR lens ( 5 ) from the one or more extracted features.
