Abstract In some industrial fields, surface temperature measurement requires speed and accuracy. Using infrared thermometer to measure temperature directly is fast, but the accuracy is low. Based on a target of high emissivity, a method of measuring the surface temperature fast and accurately is proposed. The target which made by high emissivity paint can help eliminate the surface emissivity effects on the accuracy of infrared temperature measurement when used in site. At the same time, the influence of ambient temperature, atmospheric temperature, measuring distance, atmospheric attenuation and other factors can be eliminated by comparing the direct measurement and target measurement results. Experimental results and theoretical analysis show that the proposed method can effectively improve the accuracy of infrared surface temperature measurement and the average error of the method is lower than 1%.
