There are judgement of the invention is not interfered with when passenger, the present invention utilizes face recognition technology, to face's picture of target person
Corresponding face image carries out tracking lock.
Further, since need to obtain in real time in driving procedure the current face image of driver and desired face image into
Row compares.It is thus necessary to determine that expectation face image.Meanwhile the expectation face image should be as an object of reference
React face's picture when driver's normally travel automobile with being expressly understood that, to reduce unnecessary interference.
Further, the calling and after opening photographing module step, further comprises the steps of:
It obtains target person and faces at least two face pictures immediately ahead of automobile, determined according to the face picture current
Expectation face image.
Before automobile does not travel or in driving process, user adjusts the position of photographing module, starting setting expectation face
When the relevant operation of image.Character facial picture when the photographing module is to target person normally travel carries out shooting and fixes.
It is understood that driver can voluntarily show movement expression when oneself normal driving, to complete before automobile does not travel
It is expected that the crawl and setting of face's portrait.It, can be by again to desired face when driving next time or when driver replaces
Portrait is grabbed and is set, to be updated to desired face portrait.
The present invention faces face's picture immediately ahead of automobile by obtaining multiple target persons, by multiple character facial pictures
Matching comparison is carried out, is made up by certain rule, expectation face image is generated, reduces deviation to avoid due to it is expected face
There are influence brought by deviation for image.
Target person (referring to driver) face image accessed by current photographing module is reached with desired face's picture difference
When to a certain extent, the present invention can determine whether the state that look straight ahead is not in for driver at this time, at this time to the braking control of vehicle
Unit processed issues intervention signal, by the speed control of vehicle safety traffic state.
In the present invention, intervention signal is issued to the brak control unit of vehicle, is to pass through CAN bus.CAN bus is one
The channel communicated between electronic control unit in the common vehicle of kind, as long as pre-set corresponding control signal, the present invention
Technical solution can to the brak control unit of vehicle issue speed control intervention instruction.

It is understood that the camera data, which can be real time video data, is also possible to real time picture data.If
When being real time picture data, number of times of imaging in the reasonable set regular hour, rationally to obtain the face image of target person
Data carry out matching comparison, avoid camera shooting number it is too low caused by influence.
Step S102. extracts the face image of target person from each frame of the camera data, and determines the face
The difference degree value of portion's image and current expectation face image.
Specifically, in the step of face image of target person is extracted in each frame from the camera data, packet
It includes:
The face image of target person is identified and determined from each frame of the camera data；
Extract the I frame data of the face image.
Further, the step of the determination face image and the difference degree value of the expectation face image obtained in advance
In rapid, comprising:
Obtain the I frame data of expectation face image；
The I frame data of the face image and the I frame data of the expectation face image are compared, determine difference degree value.
From the foregoing, it will be observed that either video data or real-time dynamic picture data, are all by the picture of the another frame of a frame
It constitutes.
I frame (I frame) is also known as Intra pictures (intra picture), and I frame is usually that (MPEG is used each GOP
A kind of video compression technology) first frame, can be as figure as the reference point of random access by moderately compressing
Picture.During mpeg encoded, partial video frame sequence is collapsed into I frame；P frame is partially compressed into；There are also be partially compressed into B
Frame.I frame method is frame data compression method, also referred to as " key frame " compression method.I frame method is based on discrete cosine transform (Discrete
Cosine Transform) compress technique, this algorithm is similar with JPEG compression algorithm.It can reach 1/6 using the compression of I frame
Compression ratio and without apparent compression trace.
Frame is the basic unit for forming video image.Key frame is also I frame, it is the important frame in interframe compression coding；
It is the coded frame of full frame compression；Only use the data of I frame with regard to restructural complete image when decoding；I frame is without necessarily referring to it
His picture and generate.Video file is made of multiple continuous pictures.
By obtaining the face image in each frame picture in camera data, by the face image and desired face
Image compares matching, with the difference degree value between the current face image of determination and expectation face image.The difference journey
Angle value can change according to the positional relationship of the face (eyebrow, eye, mouth, nose, ear) of both current face image and desired face image
It makes, can also be made according to the similarity of comparison general image.
In the present solution, the I frame data for obtaining video or dynamic realtime picture are compared with desired face image,
It can accelerate video data and dynamic realtime image data with desired face image to specific speed, more efficiently determination is currently driven
The face image of person's of sailing (target person) and the difference degree value of desired face image, thus the change of face's picture to driver
Change makes a response in time.
Step S103. judges that the difference degree value reaches whether duration of predeterminable level value reaches the preset time
Threshold value.
When the difference degree value is more than certain setting value, illustrate the variation of face's picture of active user, to driving
For automobile, there is great hidden danger.The setting value, i.e. predeterminable level value can be adjusted according to the practical habit of user
It is whole.Preferably, the predeterminable level value is preferably 30%.When the difference degree value of the face image He desired face image is
30%, that is, when there is 30% difference, reach the predeterminable level value 30%, triggering speed control model will be met
One condition.
Obviously, during driving, we may also look around the traffic environment of surrounding, so as to cause face's picture
Variation causes the difference degree value to change so that face image captured by shooting module also changes therewith.For this pole
The behavior for failing to face vehicle front for of short duration driver, if it is unreasonable for triggering relevant speed control model.This
Scheme reasonable set, takes, when the real-time face image of driver and the difference degree value of desired face image
Reaching predeterminable level value continue for the sufficiently long time, trigger speed control model.When triggering, the current garage of system monitoring
Sail situation and according to actual travel speed and the driving condition of duration control automobile.
Step S104. is if so, start corresponding speed control according to the travel speed of the duration and current automobile
Molding formula.
The duration that the difference degree value reaches predeterminable level value, which reaches preset time threshold, can trigger speed control
Molding formula.
For example, the difference degree value of the face image and desired face image is 35%, it is greater than predeterminable level value 30%,
It has been more than preset time threshold 2s when duration is 2.1s.Therefore, speed control model is triggered.Speed control model
Under, according to the travel speed that the duration and automobile are current, suitable mode is selected to adjust the driving condition of automobile
It is whole.
It is understood that assuming that the speed of traveling is slow enough, the difference degree value reaches continuing for predeterminable level value
Time will not constitute traveling longer dangerous.Therefore, in speed control model, not only to consider the difference degree
Value reaches the duration of predeterminable level value, also to consider the speed of current running car.
Obviously, influence of the value of the travel speed and the duration to speed control model can be according to actual
Situation is adjusted.
For example, specifically, it is described that corresponding speed control is started according to the travel speed of the duration and current automobile
In the step of molding formula, comprising:
Obtain the travel speed v of current automobile；
If when v < 20km/h, when the duration is 6s or more, controlling the travel speed v is 0；
If when 20km/h≤v < 60km/h, when the duration is 4s or more, limiting the increase of travel speed v；
If when v >=60km/h, when the duration is 2s or more, controlling automobile with the speed reduction of 5km/h per second.
In another example when the duration is 7s or more, controlling the travel speed v is 0 when v < 30km/h；If 30km/h≤v
When < 65km/h, when the duration is 5s or more, the increase of travel speed v is limited；
If when v >=65km/h, when the duration is 3s or more, controlling automobile with the speed reduction of 5km/h per second.
The method for controlling driving speed of automobile of the invention target person according to accessed by current photographing module (refers to driving
Member) when it is expected face image and face's picture difference reache a certain level and duration reaches long, it can determine whether to drive at this time
Member is not in the state of look straight ahead, intervention signal is issued to the brak control unit of vehicle at this time, by the speed control of vehicle
In the state of safety traffic.
