Abstract

Infrared thermal imager is increasingly used in different fields in production and life, as it possesses the advantages of quick response and non-contact. However, the accuracy of temperature measured by infrared thermal imager is affected seriously by surface emissivity, which limits the use of infrared thermal imager. This paper proposes an on-line measurement of surface temperature by infrared thermal imager based on an infrared target. The experimental results show that the proposed method reduces the error of temperature measurement to about 2%.
