The high level of stress in modern life is one of the huge problems of the 21st century society, especially in the context of the Covid-19 pandemic. With the pandemic, the need for inexpensive, portable and easy-to-use health monitoring tools (mental and physical) has increased. Of particular importance here is mobile (smartphone) thermography, as it enables the initial detection and self-control of stress, which being intensified nowadays, is the cause of many diseases, depression and health problems. The smartphone thermal imaging camera responds to the strict sanitary guidelines, offering contact-free, painless and non-invasive operation. Additionally, it is included in the group of low-cost solutions available for home use. It is an alternative to commonly used (often expensive and unavailable to everyone): EMG, ECG, EEG, GSR or other high-cost stress detection tools. Thermal imaging by analyzing abnormalities or temperature changes allows for detection application. Therefore, the aim of this work is to determine the possibilities of a low-budget mobile thermal imaging camera in detecting stress, detecting and analyzing stress by identifying the characteristics of psychophysiological signals with the individual characteristics of the participants, along with the correlation. The participants' reactions to the film introducing stress tension up to the climax of the action were recorded thermographically. Data was processed in OpenCV. In the usual observation, stress often remained unnoticed. However, the thermographic analysis provided detailed information on the impact of the film's stressful situation on the participants, with the possibility of distinguishing the stages of stress. The results of the preliminary pilot study were presented, which indicated the variability of temperature and heart rate as important indicators of stress - with the simultaneous significance of individual characteristics of the participant. Smartphone stress thermography is a promising method of monitoring human stress, especially at home.
现代生活中的高压力水平是21世纪社会面临的重大问题之一，尤其是在新冠疫情的背景下。随着疫情的爆发，对廉价、便携且易于使用的健康监测工具（包括心理和身体方面）的需求增加了。在此，移动（智能手机）热成像技术尤为重要，因为它能够对压力进行初步检测和自我控制，而压力如今不断加剧，是许多疾病、抑郁症和健康问题的根源。智能手机热成像相机符合严格的卫生准则，提供非接触、无痛且无创的操作。此外，它属于可供家庭使用的低成本解决方案之一。它是常用的（通常昂贵且并非人人都能使用）肌电图、心电图、脑电图、皮肤电反应或其他高成本压力检测工具的替代方案。通过分析异常或温度变化的热成像技术可用于检测应用。因此，这项工作的目的是确定低成本移动热成像相机在检测压力方面的可能性，通过识别参与者的个体特征以及相关性来检测和分析心理生理信号特征以确定压力情况。通过热成像记录了参与者对引发压力紧张直至动作高潮的影片的反应。数据在OpenCV中进行处理。在通常的观察中，压力往往未被注意到。然而，热成像分析提供了关于影片压力情境对参与者影响的详细信息，并且有可能区分压力阶段。展示了初步试点研究的结果，这些结果表明温度和心率的变化是压力的重要指标，同时参与者的个体特征也具有重要意义。智能手机压力热成像技术是一种很有前景的监测人类压力的方法，尤其是在家中使用时。
