Embodiment
[0050] see figure 1 , the classification method of the motor imagery EEG signal based on deep learning of the present embodiment, comprises the following steps:
[0051]Step 1: Acquisition of experimental data, that is, collecting the original EEG signal data set, the subject wears an electrode cap during collection, and the original EEG signal is performed through the 64-lead EEG amplifier of the 10-10 method calibrated by the International Electroencephalography Association Collect and select all electrode positions. Each subject will conduct 14 experiments. When collecting, the subject sits on a chair, and there is a screen in front of the subject, and there is a target on the screen: the first two experiments It is a basic experiment lasting 1 minute. The basic experiment includes opening and closing the eyes, that is, in the first two experiments, the eyes were opened for 1 minute and the eyes were closed for 1 minute; then there were three cycles of experiments, and each...
