便携式红外热像仪外场测温误差分析及修正

红外测温成像技术精度的影响因素较多。尤其在实验外场的复杂环境下，有时难以达到预期指标。为了有效提高便携式红外热像仪的外场测温精度，利用红外测温理论模型梳理和总结了外场测温的主要影响因子，然后利用外场实测数据对其进行了统计分析，并提出了相应的修正方法。结果表明，修正后的数据标准差由0.89 K降至0.3 K，有效提高了测温精度。

Error Analysis and Correction of Field Temperature Measurement for Portable Infrared Thermal Imager

There are many factors affecting the accuracy of infrared temperature imaging technology. Especially in the complex environment of the experimental field, sometimes it is difficult to reach the expected index. In order to effectively improve the measurement accuracy of portable infrared thermal imager in the field, the main influencing factors of the field temperature measurement are sorted and summarized by the infrared temperature measurement theoretical model, and the influence factors are statistically analyzed by using the measured data in the field in the paper. In addition, the corresponding correction method is proposed. The results show that the standard deviation is reduced from 0.89 K to 0.3 K after the correction, which effectively improves the temperature measurement accuracy.
