In order to improve measurement accuracy, a double-band pyrometric method based on emissivity compensation has been proposed for steel under laser irradiation. With exponential models as emissivity model, the measurement errors are below 4%. Meanwhile the comparison between the traditional double-band method and this method has been conducted, and the precision of this method is obviously higher. The quantitative analysis of data processed by this method shows that, the calculation errors are between 13 ℃ and 25 ℃.
