| 摘 要： | 为了提高激光辐照下加热点处红外测温精度，建立了多变量测温补偿模型，研究了测量距离、测量角度与测量精度的关系。采用单一变量与正交变量结合的方法，建立关于测量距离与测量角度的二元变量补偿模型，并进行误差补偿模型验证实验。结果表明:补偿模型与实际测量结果可以较好地匹配，补偿后测量误差为±1.25%，与补偿之前相比测量精度提高64.25%，验证了补偿模型的正确性，为激光辐照下加热点温度红外测量提供理论指导。

| Abstract: | In order to improve the infrared temperature measurement accuracy at the heating point under laser irradiation, a multivariate temperature compensation model was established, and the relationships among measurement distance, measurement angle and measurement accuracy were analyzed. A binary variable compensation model for measuring distance and angle was established by using single variable method and orthogonal variable method, and the error compensation model was verified by experiments. The results show that the compensation model can match the actual measurement results well. The measured error after compensation is ±1.25%, which improves the measurement accuracy by 64.25% compared with that before compensation. This verifies the correctness of the compensation model, which can provide theoretical guidance for infrared measurement of heating point temperature under laser irradiation. |
