Baby's face image is narrowed down to the zonule of only eyes and nose, coarse positioning eyes and nose using sciagraphy
Region.
Denoising and enhancing processing are carried out to the area image of eyes and nose.It is distributed from vertical direction, nose is in eyes
In the following, searching for from top to bottom, the region of eyes and nose can be oriented.
The region of eyes and nose is accurately positioned using template matching method.
Traditional template matching method, is matched that not only operand is big but also disturbing factor is more in entire image.This reality
With in novel because coarse localization goes out the region of eyes and nose, and without the influence of the organs such as eyebrow, mouth, institute
Continuously to make the position that horizontal and vertical projection takes its intersection point to be positioned as eyes and nose to image, accuracy rate is improved.
Step 4 to step 6 refers to Fig. 4, eyes in a kind of baby's face image that Fig. 4 the utility model embodiments provide
With the coordinate sampled point schematic diagram of nose.

Wherein, T1For the second relative distance, T2For absolute distance, T3For the first relative distance, OFFSET1And OFFSET2For
The error compensation of facial image is acquired, error compensation needs manually to set due to the difference of machine.
By the first relative distance obtained in step 4-6, the second relative distance, absolute distance and preset error
Compensation substitutes into the value that θ is found out in eye state formula.
When θ is smaller, closer to 0, illustrate that eyes are more closed, ideally, the theoretical minimum value of θ is 0；
Otherwise θ is bigger, closer to 1, illustrate that eyes are more opened.
Due to baby's individual difference, the θ values that eyes are opened vary with each individual, therefore, can be according to different baby's individuals, in advance
Threshold value is first set, θ is compared with threshold value to detect.
So far, it may determine that baby's eyes are in by the size of θ values and open state or closed state.
If eye state is eyes-open state, and continues to determine within 5~10 seconds that baby is in waking state；Because of baby
Eyes also can be opened to transience in sleep procedure, but can close eyes again quickly and continue to sleep, therefore can select to open eyes
State is for 5 seconds, 6 seconds, 7 seconds, 8 seconds and 9 seconds judge whether baby regains consciousness, the time is too short to be easy to cause erroneous judgement, overlong time
It is easy missing inspection baby's waking state, can turn over or creep after baby is awake, it is easy to fall under bed, cause irremediable
Injury.
If eye state is closed-eye state, and continues to determine within 60~300 seconds that baby is in sleep state；Because each
The time that baby enters sleep differs, therefore the duration can define according to the characteristic manual setting of baby.
