The SARS-CoV-2 virus pandemic has shown that the use of a contact thermometer to verify the elevated body temperature of a suspected person carries a risk of spreading disease. The perfect solution seems to be the use of thermal imaging as a diagnostic method in fever evaluation. The aim of the research is to develop an algorithm for thermovision measurements in fever screening standards in the context of the impact of various weather conditions on the temperature of people entering the public institution. Each examined person had two thermal images of the face-AP and lateral projection. Using a T1020 FLIR thermal camera with a resolution of 1024 × 768 pixels; the mean temperature was measured from the area of the forehead, the maximum forehead, the corners of the eyes, the inside of the mouth and the external auditory canal temperature. On the other hand, using classic contact thermometers, the temperature in the armpit and ear was measured. The obtained preliminary results showed very strong and positive correlations between the temperature in the ear measured with an ear thermometer and the maximum, minimum and average forehead temperature. These correlations oscillate at approximately r = 0.6, but the highest value of Spearman coefficient was obtained for the mean temperature of the forehead. Moreover, high correlations were also obtained between the temperature in the ear, measured with an ear thermometer, and the maximum temperature in the corners of the eyes and in the ear, measured with a thermal imaging camera. These values were, respectively, r = 0.54, r = 0.65. In summarizing, remote body temperature measurement taken with a thermal camera can be useful in the assessment of the body's core temperature.
SARS-CoV-2 病毒大流行表明，使用接触式体温计来验证疑似患者体温升高存在传播疾病的风险。理想的解决方案似乎是使用热成像作为发热评估的诊断方法。本研究的目的是开发一种算法，用于在各种天气条件对进入公共机构人员的体温产生影响的情况下，对发热筛查标准进行热视觉测量。每位受检者的面部-AP 和侧视投影都有两张热图像。使用 T1020 FLIR 热像仪，分辨率为 1024×768 像素；从额头、最大额头、眼角、口腔内部和外耳道温度的区域测量平均温度。另一方面，使用经典的接触式体温计测量腋窝和耳朵的温度。初步获得的结果表明，耳温计测量的耳朵温度与额头的最大、最小和平均温度之间存在非常强且呈正相关。这些相关性波动在 r = 0.6 左右，但额部平均温度获得了最高的斯皮尔曼系数值。此外，耳温计测量的耳朵温度与热成像相机测量的眼角和耳朵最高温度之间也存在高度相关。这些值分别为 r = 0.54，r = 0.65。总之，使用热像仪进行远程体温测量可用于评估人体核心体温。
