Psychological stress evaluation method based on fusion of electrocardiosignal and electromyographic signal

Abstract

The invention discloses a psychological stress evaluation method based on fusion of an electrocardiosignal and an electromyographic signal, and belongs to the technical field of psychological stress analysis. The method aims at solving the problems that existing psychological stress evaluation more emphasizes subjectivity of a subject, and the stress state of the subject cannot be objectively reflected through physiological or behavioral characteristics. The method comprises the steps of acquiring an electrocardiogram physiological parameter and an electromyographic physiological parameter; acquiring all to-be-recognized characteristics of the electrocardiogram physiological parameter and the electromyographic physiological parameter; fusing all the to-be-recognized characteristics througha random forest characteristic importance measurement method algorithm, and allocating weights in a stress recognition model to obtain a final stress recognition model; acquiring and processing the electrocardiosignal and a surface electromyographic signal of the subject to obtain to-be-tested characteristics of the subject; and inputting the to-be-tested characteristics of the subject into the final stress recognition model to obtain the current psychological stress level of the subject.
