Target detection method and system based on auditory brain-computer interface

The invention relates to a target detection method and system based on an auditory brain-computer interface, and the method comprises the steps: collecting an electroencephalogram signal of a user in real time, carrying out the preprocessing of the electroencephalogram signal, and obtaining the characteristics of the electroencephalogram signal; the features of the electroencephalogram signals are classified, a classification result is obtained, whether neural representation corresponding to a sound target appears or not is judged based on the classification result, and a judgment result is output; and judging whether the sound target exists or not according to the judgment result. According to the target detection method and system based on the auditory brain-computer interface provided by the invention, the robustness of a current sound target detection system to environment interference and a new target sample is improved, so that the performance weakness of the sound target detection system is improved. 本
