Embodiment Construction
[0051] see Figure 1-8 , EEG-based emotional perception system for teenagers' environmental psychology, including EEG signal acquisition module, EEG signal preprocessing module, EEG signal feature extraction module and emotion perception module; based on the built environment that teenagers often contact, participate in or are passionate about As the source of visual stimulation, the subjects were teenagers;
[0052] The EEG signal acquisition module is used to collect the original 32-lead EEG signals of the subject through the recording electrodes and the reference electrodes, and send the collected original EEG signals to the EEG signal preprocessing module; The 32-lead EEG signal was acquired by using the international 10-20 system electrode placement method, and each electrode corresponds to one EEG signal. The electrode placement method of the international 10-20 system adopted in the present invention: place 30 recording electrodes and 2 reference electrodes, and the la...
