In recent years, optical imaging techniques have been widely recognized for their ability to measure vital signals such as heart rate, respiratory rate, oxygen saturation, and blood pressure, which are important indicators of human health. Various optical imaging methods including RGB imaging, thermal imaging, hyperspectral imaging, depth imaging, and multimodal imaging provide spatial information and have extensive applications in remote physiological signal monitoring. This survey provides a comprehensive overview of the principles, data analysis methods, advantages, disadvantages, applications, and future prospects of optical imaging methods for vital signal measurement.
In recent years, optical imaging techniques have gained wide recognition for the measurement of vital signals, such as heart rate, respiratory rate, oxygen saturation, and blood pressure, which are crucial indicators for evaluating human health conditions in clinical examinations. There is a wide range of optical imaging methods for remote physiological signal monitoring, including RGB imaging, thermal imaging, hyperspectral imaging, depth imaging, and multimodal imaging, which provide spatial information compared to other noncontact measurement approaches, thereby allowing extensive applications in this area. In this survey, some fundamental knowledge about optical imaging methods for vital signal measurement is reviewed, including principles of various optical imaging techniques, processing methods for data analysis, discussion on advantages and disadvantages, application summary, and future prospects. This is a comprehensive overview of the noncontact physiological signal measurement of optical imaging approaches.
