红外图像型测温中距离与像素间定量关系的研究

The research on the quantitative relationship between distance and pixel values in temperature measuring using infrared images

在研究了红外测温理论的基础上,通过黑体实验得到"温度—像素"和"像素—距离"曲线,对实验数据进行挖掘和处理后,建立了一种与距离无关的红外图像型测温方法,并给出了系统的实际应用模型。实验证明,该模型能够满足实际的测温精度要求。

This paper explains the infrared temperature measurement theory. It acquires the function curve of temperature and pixel values, so as the function curve of pixel values and distance. After processing those data, it builds a temperature measuring method using infrared pictures without reference to distance and also establish the application model of system. Experiment proves that this model can meet general accuracy requirements for temperature measurement.
