By human eye displacement, i.e., the relative distance between the eyes centre coordinate for obtaining twice, with distance
Threshold value is compared.If the distance moved twice before and after human eye is more than distance threshold, judge that human eye is moved
Dynamic amplitude is larger, user still in waking state, without starting park mode.If before and after human eye twice
Mobile distance is less than distance threshold, then user is likely to be at sleep state, now needs further to human eye
Closure be identified, accurately to judge the present situation of user.
Before human eye closure is recognized, the misalignment to human eye judges the present embodiment in advance, such as
Fruit human eye displacement amplitude is larger, then directly judge that user is in waking state, without starting park mode,
