Abstract:

Acquisition of learning status data is the premise of intelligent education, and physiological parameters are important information to reflect students’ learning status. However, in the field of intelligent education, the detection method of physiological parameters is relatively single, still mainly in contact, and has some limitations. The non-contact physiological parameter detection method is more conducive to the wide spread of intelligent education. The non-contact physiological parameter detection method based on video is analyzed. Firstly, the principle of the imaging photoelectric volume tracing technology is introduced, then its development and current situation are summarized and analyzed, and the relevant applications of physiological parameter detection in the field of education in recent years are summarized. Finally, the development trend of video-based non-contact physiological parameter detection in the field of education is summarized and prospected.
