摘要
根据热辐射理论和红外热像仪的测温原理,推导出计算被测物体表面真实温度的通用计算公式.阐述了红外热像仪在测温过程中容易忽视的影响精度测量的因素,为进一步提高测量结果的准确性,提出了解决方法.
Based on the principles of thermal radiation and temperature measurement with infrared thermal imager, a general computing formula of the true surface temperature of a measured object is given in order to increase the veracity and precision of a measure result. The aspects are expatiated which affect the precision of temperature measurement but are liable to be ignored in the course of temperature measurement with infrared thermal imager. Solutions therewith are also given.
