The invention relates to an electrocardiograph and respiratory signal synchronous characteristic based emotion detection method. The method includes: acquiring ECG (electrocardiograph) signals and respiratory signals; preprocessing; extracting characteristics including 1) time domain synchronous characteristics, 2) frequency domain synchronous characteristics and 3) phase lock valves; assessing separability of each characteristic according to a Fisher discriminant ratio, calculating to finally obtain FDR (Fisher discriminant ratio) values of five characteristics, and distributing corresponding weight value wi to each characteristic according to the FDR values; adopting a SVM (support vector machine) for establishing an emotion recognition model to recognize a current emotion state of a user. The electrocardiograph and respiratory signal synchronous characteristic based emotion detection method has the advantage that accurate real-time emotion monitoring can be realized.
