以红外辐射理论及红外热像仪测温原理为基础，为解决环境高温物体对红外测温的影响，提出反射温度补偿和入射温度补偿两种方法。分析了两种温度补偿方法的理论可行性和实际操作方案并具体进行实验测温对比。对4个硫化矿样本分别应用两种补偿方法同未经补偿的红外测温进行实验测温对比研究，分析结果显示：经过温度补偿后，相对误差明显小于未经补偿的红外测温，且反射温度补偿法较入射温度补偿法更为精确，验证了两种温度补偿方法的可用性及精确性。两种补偿方法在保证测量精度的同时拓宽了普通红外热像仪的应用范围，保证了硫化矿自燃红外预测数值精度。

Based on the basic theory of infrared radiation and principles of temperature measurement using infrared imager, two methods of temperature compensation were proposed, reflected temperature compensation and incidence temperature compensation, in order to ensure environmental temperature object has less of an effect on infrared measurement. The theoretical analysis proved its feasibility and the operation program was put forward and used in production. The compensation measurements were demonstrated in a laboratory experiment with four sulfide ore samples. The results show that the fitting of compensation measurement with true temperature is better than that of common infrared measurement. The fractional error of reflected compensation measurement significantly is less than the incidence. The theoretical analysis and experiment result indicate the feasibility of the proposed methods. The compensation measurements ensure the measurement accuracy as well as expand the scope of common thermal infrared imager application and ensure the numerical accuracy of infrared prediction in the spontaneous combustion of sulfide ores.
