[Abstract]:The accuracy of infrared temperature measurement is influenced by many factors and has the characteristics of nonlinearity and high complexity. In order to improve the accuracy of infrared temperature measurement, the effects of ambient temperature, measuring distance and emissivity on the accuracy of infrared temperature measurement are analyzed. The infrared temperature measurement method based on buttocks is studied, and the diffusion model of temperature field is established, which is transformed from hip surface temperature to actual body temperature. The partial least square method and artificial neural network are used to optimize and compensate the temperature field model. It effectively solves the problem of multiple correlation among various factors and the nonlinear problem of compensation model, and improves the reliability of the system. The experimental results show that the temperature measurement error range of the proposed infrared temperature compensation model is -0.12 ~ 0.11 鈩，
