It sets.
The related description and effect of the vehicle mirrors adjusting method of Fig. 6 and Fig. 7 illustrated embodiments refer to Fig. 3 and Fig. 4
The related description of the vehicle mirrors regulating system part of illustrated embodiment, does not repeat one by one herein.
Fig. 8 is the positioning driver eye position according to the vehicle mirrors adjusting method of one embodiment of the present invention
Flow diagram.As shown in figure 8, handling in the step s 120 the image of the driver, to position the driver
Eye locations include：In step S122, similarity calculation is carried out to the image of the driver；It is right in step S124
The image for carrying out the driver after similarity calculation carries out binary conversion treatment；In step S126, to carrying out at binaryzation
The image of the driver of reason carries out Gray Projection both vertically and horizontally, with the facial regions of the determination driver
Domain；And in step S128, eye feature is determined by aspect ratio pair and/or traversing operation, with the determination driver's
Eye locations.
As an example, in step S122, similarity calculation is carried out to the image of the driver according to following formula：
Wherein, x for target point in the image of the driver acquired abscissa；Y is the driving that is acquired
The ordinate of target point in the image of member；f1(x, y) for target point in the image of the driver acquired pixel pair
The gray value answered；F (x, y) is the gray value for carrying out the image of the driver after similarity calculation；A, b and c is according to ring

In said program, similarity calculation first is carried out to target image, the pixel gray value of target image is become more
Adding uniformly, the influence that can reduce environmental factor in this way improves the accuracy rate of detection, after the image after obtaining similarity calculation,
Binary conversion treatment is carried out, i.e., it is by face pixel all in image to be all provided with and be set to white or black, main function
Background in image and image carries out differentiation processing, keeps human face region more obvious, improves discrimination.It is needed after binary conversion treatment
Image is to obtain the vertical direction of face and water both vertically and horizontally carrying out Gray Projection, main function respectively
Square to region, one rectangular area of determination that thus can be rough, which is human face region.Obtaining face area
Behind domain, orientation range definitely, makes the accuracy rate of algorithm is opposite to improve in this way.Therefore on the basis of human face region, to this
Region carries out edge detection, and major function is to delete the irrelevant information of this panel region, only retains the important feature of face area
Realize the human eye location algorithm of Gray Projection.It the operations such as compared, traversed by these features and human eye feature to find obviously
Eye feature point, then the point is face eye locations, to realize the human eye location algorithm of Gray Projection.
As another example, in step s 130, according to the eye locations of the driver positioned, according to following public affairs
Formula calculate the inside and outside angle [alpha] of the rearview mirror '：
α '=a ' x '
Wherein, a is inside and outside angular adjustment parameter；X ' is the abscissa of driver's physical location；
Fig. 9 is that angle adjusts position view inside and outside rearview mirror.As shown in figure 9, rearview mirror is in outermost extreme position
It is set as 0 degree of angle, rearview mirror is inwardly until the angle that the limit is rotated is α, at this point, what corresponding driver eye position moved forward
Distance is then xmax, it can be seen that the angle that the distance and rearview mirror of the movement of driver eye position are adjusted is closed at certain ratio
System.If：Inside and outside adjustment parameter is a, be can be obtained：α=a ﹒ xmax, it is possible thereby to calculate to obtain inside and outside angular adjustment parameter a.
It is described to adjust eye locations of the processing unit according to the driver positioned, described in the calculating of following formula
The angle beta up and down of rearview mirror '：
β '=by '
Wherein, b is upper and lower angular adjustment parameter；Y ' is the ordinate of driver's physical location.
Figure 10 is that lower angle adjusts position view on rearview mirror.As shown in Figure 10, when the eye locations of driver are along Y
When axial upper (lower) mobile, rearview mirror needs the central point along j axis to move, i.e., backward (preceding) relative to the V points of rearview mirror upper edge
Rotation.Backsight eyeglass is set as 0 degree of angle in the extreme position on most, and backsight eyeglass is to until the angle of extreme rotational is β, at this time
The distance that corresponding driver eye position moves up is then ymax.If：Up and down adjustment parameter is b, be can be obtained：β=b ﹒ ymax, by
This can calculate to obtain angular adjustment parameter b up and down.
If actual position coordinate is (x ', y ') in the car for driver institute, then can be calculated in required rearview mirror
Outside, up and down adjustment rotation angle is respectively：
Wherein：αk、αk-1、βk、βk-1Inside and outside angle, this inside and outside angle adjusted, rearview mirror respectively residing for rearview mirror
Residing upper lower angle, this upper lower angle adjusted, when △ α or △ β value is timing, control stepper motor rotates forward, as △ α or
When △ β value is negative, control stepper motor reversion.To obtain rearview mirror required inside and outside, adjusting rotation respectively up and down from origin
Angle (Δ α, Δ β), to reach the suitable position of rearview mirror, the angle of rearview mirror is automatically performed according to the position of driver
It adjusts, security risk caused by being adjusted manually in avoiding driver from travelling improves drive safety.
