[0066] Construct driving suitability into k degrees, F k Indicates driving suitability, and t indicates continuous driving time. Taking the construction of 8 degrees of fitness with a step size of 0.5 hours as an example, each fitness category is as follows (F 0 to F 8 driving suitability decreases in turn):
[0067] f 0 : t<0.5 hours
[0068] f 1 :0.5 hours≤t<1 hour
[0069] f 2 :1 hour≤t<1.5 hours
[0070] f 3 : 1.5 hours ≤ t<2 hours
[0071] f 4 : 2 hours ≤ t<2.5 hours
[0072] f 5 : 2.5 hours ≤ t<3 hours
[0073] f 6 : 3 hours ≤ t<3.5 hours
[0074] f 7 : 3.5 hours ≤ t<4 hours
[0075] f 8 : 4 hours ≤ t.
[0076] In order to avoid light leakage and pupil changes caused by visual attention itself, the fatigue detection glasses adopt an integrated closed glasses structure, and use black light-absorbing material on the outer layer, and flexible silicone material at the joint between the glasses and the face. The fit of the face and the glasses is equivalen...
