Research on Related Attribute of Pilot Fatigue Based on Eye Tracker
Fan We · Computer Technology and Development · 2014
Pilot's driving fatigue is one of the important factors that affect flight safety.Eye tracker has been trying to apply to driver fatigue detection,but eye tracker collects too many data attributes,lacks of a clear decision attribute.It will make PVT( Psychomotor Vigilance Task) into the data get by eye tracker,as decision attribute,use the rough set attribute reduction method based on binary channel of mutual information for attributes reduction of eye tracker in view of the fatigue test,and before and after the reduction,use BP neural network to classify respectively.Results show that use the binary channel mutual information as the heuristic information to test fatigue by attribute reduction,it can effectively extract the main pilot fatigue properties.
