The invention relates to the field of EEG identification, can realize identification by taking an EEG signal as biological feature in the mode of imagination action, and is high in accuracy and repaid. In order to achieve the aim, the invention adopts the technical scheme that an imagination action EEG identification method based on fusion feature comprises the steps of: in the process of imagination action executed by a subject, collecting the corresponding EEG signal; after the pretreatment such as removing noise and the like, respectively extracting the EEG characteristic of a single channel and the cross-channel EEG characteristic of the opposite sides of cerebral hemisphere, and fusing the characteristics; then, carrying out dimension reducing operation on the fuse characteristic for optimizing and reconstructing; and finally, sending into a sorter for classified studying and testing, and achieving the aim of identification. The invention is mainly applied to EEG identification.
