More Information
Summary:The invention discloses a driver fatigue detection method and system during closed cabin underwater operation. The method comprises the steps that brain/electromyographic signals of a driver are collected; performing signal amplification, noise reduction and filtering on the brain/electromyographic signals, judging whether signal abnormity or missing exists in the brain/electromyographic signals or not, and if yes, correcting the abnormal or missing signals; electroencephalogram time domain/frequency domain/time frequency characteristics and myoelectricity time domain/frequency domain characteristics are obtained; calculating a similarity value between each sub-feature value in the brain/myoelectricity time domain/frequency domain/time frequency feature and a corresponding reference sub-feature value in the fatigue-free set; counting whether the accumulated sum of the similarity values is greater than or equal to a set threshold value, if so, determining that the driver is in a fatigue-free state, and if not,
