摘　　要：红外测温技术是一种非接触式测温方法,相比传统测温方式,具有无损伤、非接触、快速实时、远距离、测温范围宽等优点。目前已在建筑、电力工业、航天航空、质量检测及冶金等领域获得广泛应用。本文首先,基于红外全辐射原理建立了测温模型;其次,根据试验数据发现,热成像系统的输出随开机时间有一定温度漂移,经过理论分析红外热像系统的输出特性,考虑热成像系统的温度漂移,对已有模型进行改进;最后,采集大量数据对测温模型进行验证,发现该算法很有成效。At the same time,it plays an important role in the field of image processing and Infrared thermometer is widely used in various imaging system in the military,industrial and commercial fields,because its fast response,accurate,convenient,and other advantages.In this paper the temperature measurement model was established based on the theory of infrared radiation.And model was improved according to the experiment and theoretical analysis of the infrared output characteristic.Through the verification,we found that the algorithm is feasible.
