比色测温中外界环境误差的减小方法研究

Decrease Method of External Environment Error of Colorimetry of Temperature Measurement

基于比色测温原理,论述了对比色测温测量精度影响较大的外界环境因素。通过理论研究,提出从比色测温双波段采集到的信息中除掉外界环境干扰因素的思路,并通过对大量实验数据的处理分析,得出最佳的校正模型,提高了比色测温的测量精度。

Based on the colorimetry of temperature measurement, the environmental factors which influence the accuracy of colorimetric temperature measurement much more are discussed. Through theoretical analysie, a thought is put forward that the interference of the external environmental factors can be removed from the colorimetric temperature measurement of dual band collected information. Through the treatment and analysis of experimental data, the best calibration model is obtained, and the accuracy of colorimetric temperature measurement is improved
