Motor is inverted, wiper adverse movement eliminating water.
The control method of rearview mirror assembly：
1st, the determination of motor commutating period：
When driver is selected under automatic mode, the rainfall size according to rain sensor transmission determines the operating frequency of wiper
And operating rate, operating frequency f of wiper becomes following linear relationship with rainfall w：
298N chip operation cycle T is adjusted to by controller：
Operating rate v of wiper becomes following relation with rainfall size：
Wiper from medial motion to outside the time required to be：
L refers to the horizontal length of rearview mirror, k1,k2, a, b, n be respectively default parameter.
2nd, face recognition algorithms：
Obtain face image set Q for being possible to R people for driving the car.According to the pixel arrangement per an image, can
So that the vector of a S dimension is converted thereof into, R vector is put in a set Q, is shown below：
Q={ W1,W2,W3,……,WR}
Institute's directed quantity in face vector set Q is carried out the cumulative such as following formula of traversal, according to gathering for meansigma methodss composition
To a average image：
Above-mentioned meansigma methodss are deducted with each element in S set, difference Ω per an image and the average image can be calculated：
Ωi=Wi-β
Find M orthogonal unit vector Un, these unit vectors be used in fact describe ΦiDistribution.UnThe of the inside
The individual vector U of k (k=1,2,3...M)KCalculated by following formula：
When this eigenvalue λkWhen taking minimum value, UKSubstantially determine that.UKFollowing formula will also be met：
Above equation causes UkFor unit orthogonal vectors.Calculate U abovekIt is exactly to be calculated as follows covariance matrix in fact
Characteristic vector：
Wherein A={ Ω1,Ω2,Ω3,……,ΩT}
Several steps are to find, in order to carry out dimensionality reduction to face, the suitable vector for characterizing face above.Consider first one new
Face, can be indicated to which with eigenface：
Wherein k=1,2...M, for k-th eigenface uk, above formula can calculate its corresponding weight, and M weight is permissible
Constitute a vector：
YT=[ω1,ω2,ω3,……,ωM]
Finally judgement identification is carried out to face, judgment formula is as follows：
εk=| | Y-Yk||
Wherein Y represents face to be differentiated, YkCertain face in training set is represented, both by the power of eigenface
Again representing.Euclidean distance is asked to both, when distance is less than default threshold value in explanation face and training set to be differentiated
K-th face is same person.When all training sets both greater than default threshold value is traveled through, the size according to distance value can be divided again
For be new face or be not face two kinds of situations.
With the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
In the range of without departing from this invention technological thought, various change and modification can be carried out entirely.The technology of this invention
Property scope is not limited to the content in description, it is necessary to determine its technical scope according to right.
