通过皮肤表面温度的归一化，讨论了不同热环境条件下红外图像的比较。为了评价不同热环境条件下获得的红外图像，我们提出了一种人体热模型，该模型可以将特定热环境条件下获得的红外图像转换为其他条件下的图像。该模型是基于对表达人体内传热现象的生物传热方程的数值计算。人体几何模型采用16柱段模型。将红外图像与转换后的图像进行比较，结果表明该方法能够有效地消除热环境条件的影响。然而，转换后的图像与原始图像之间的差异在不同的片段之间是不同的。在未来的工作中，我们将使用这种方法来研究不同热环境下几个主体的红外图像。
Discusses comparing infrared images under various thermal environmental conditions through normalization of skin surface temperature. To evaluate IR images obtained under various thermal environmental conditions, we proposed a human thermal model with which IR images obtained under certain thermal environmental conditions can be converted into images under other conditions. The model was based on a numerical calculation of the bio-heat transfer equations that express heat transfer phenomena within the human body. A 16-cylinder-segment model was used as the geometry of the human body. Comparisons of IR images with their converted images indicate that this method is effective in eliminating the influence of the thermal environmental conditions. However, the difference between the converted images and the original ones varies among segments. In future work, we will use this method to investigate the IR images of several subjects under various thermal environments.
