Fig. 1 shows the summary block diagram of the safe driving of vehicle accessory system 100 according to the first embodiment of the present invention
With specific schematic diagram.As shown in figure 1, the safe driving of vehicle accessory system 100 includes image-capture portion 10, the first processing unit
20th, second processing portion 30 and control unit 40.
As shown in Fig. 2 image-capture portion 10 includes the first image-capture portion 11 and the second image-capture portion 12, it is respectively used to
Capture the external environment condition image and internal environment image of this vehicle.First image-capture portion 11 for example can be wide angle cameras,
It is installed to the vehicle body surrounding of this vehicle to obtain 360 ° of panoramic pictures.Preferably, the first image-capture portion 11 can be installed to
At the front bumper or windshield of this vehicle, to capture the external environment condition image of this vehicle front.Second image-capture portion 12
Can also be wide angle cameras, it is arranged on above the instrument board of this vehicle, room mirror is nearby or on the A posts of left side.Second
Image-capture portion 12 can capture the internal environment image of the face-image including driver, upper part of the body image etc..
First processing unit 20 is based on external environment condition image recognition this vehicle periphery captured by the first image-capture portion 11
Road environment.For example, as shown in Fig. 2 the first processing unit 20 includes calculating part 21, for calculating the average bright of external environment condition image
Angle value；And determination unit 22, for by will be entered by the average brightness value that calculating part 21 obtains and multiple threshold values set in advance
Row relatively judges the road environment of this vehicle front.
The external environment condition image captured by the first image-capture portion 11 is changed into multiple pixel (examples by calculating part 21 first
Such as, resolution ratio is 800 × 600 480,000 pixel), wherein each pixel has corresponding (R, G, B) numerical value.Then, count
Calculation portion 21 calculates the brightness of each pixel.For example, calculating part 21 (R, G, B) numerical value of each pixel can be converted into (L, a,
B) model, wherein numerical value L represent the brightness value of respective pixel.Then, brightness number of the calculating part 21 to the plurality of pixel is averaging
Value, so as to obtain the average brightness value of the external environment condition image.
Determination unit 22 is by the average brightness value obtained by calculating part 21 and multiple threshold values set in advance (for example, the first threshold
Value, more than Second Threshold of first threshold etc.) be compared, and the road ring of this vehicle front is judged based on the comparative result
Border.For example, when the average brightness value of external environment condition image is less than first threshold, determination unit 22 is determined as the road of this vehicle front
Road light is relatively dark, it means that, for example, being exactly now, or this vehicle may be sitting at tunnel, garage the dusk time-division
In.On the contrary, when the average brightness value of external environment condition image is more than Second Threshold, determination unit 22 is determined as the road of this vehicle front
Road light is relatively bright, it means that, for example, now sunlight is more dazzling or this vehicle may be travelled just on snowfield.
Whether worn based on the internal environment spectral discrimination driver captured by the second image-capture portion 12 in second processing portion 30
Wear sunglasses.For example, second processing portion 30 is analyzed by the second image-capture portion by using computer vision and pattern classification
The internal environment image of capture, to judge whether driver wears sunglasses.Specifically, second processing portion 30 passes through face first
The face-image that driver is separated in the internal environment image that is captured from the second image-capture portion 12 is detected, then from isolating
Face-image in extract driver eye around provincial characteristics (for example, shape, texture, color etc.), will then be extracted
Provincial characteristics compared with the individual features prestored, be finally based on comparative result to judge whether driver wears too

Send the early warning for wearing/removing sunglasses.For example, when the determination unit 22 of the first processing unit 20 is determined as by the first image capture
The average brightness value for the external environment condition image that portion 11 captures is less than first threshold and when second processing portion 30 is determined as driver
When having worn sunglasses, it means that driver is wearing sunglasses or will drive car under the road environment of dark
, and this situation is than relatively hazardous, thus control unit 40 sends the early warning for removing sunglasses to driver.And for example, when
The determination unit 22 of one processing unit 20 is determined as that the average brightness value of the external environment condition image captured by the first image-capture portion 11 is big
In Second Threshold and when second processing portion 30 is determined as that driver does not wear sunglasses, it means that driver does not wear too
Positive mirror but vehicle will be driven or under the stronger road environment of light, and this situation is also than relatively hazardous, thus control unit
40 send the early warning for wearing sunglasses to driver.
Therefore, according to the safe driving of vehicle accessory system 100 of the first embodiment of the present invention, can be worn according to driver
The state of sunglasses and the road environment of this vehicle front are worn, the early warning for wearing/removing sunglasses is given to driver,
So as to avoid driver in danger situation down train.
Moreover it is preferred that second processing portion 30 is also sentenced based on the internal environment image captured by the second image-capture portion 12
Determine whether driver uses sunshading board.Specifically, second processing portion 30 is caught by Face datection method from by the second image first
Obtain portion 12 capture internal environment image in separate driver's face-image, then by shadow Detection method to it is separated go out face
Portion's image is analyzed to judge whether driver uses sunshading board.For example, can judging driver's face shade to be present and
When not having shade around upper body, judgement has used sunshading board.Then, when the determination unit 22 of the first processing unit 20 is determined as by first
The average brightness value for the external environment condition image that image-capture portion 11 captures is less than first threshold and when second processing portion 30 judges
When having used sunshading board for driver, it means that driver has used sunshading board but or by the weaker road ring of light
Drive vehicle under border, and this situation is than relatively hazardous, thus control unit 40 sends the early warning for packing up sunshading board to driver.
And for example, being averaged when the external environment condition image that the determination unit 22 of the first processing unit 20 is judged to being captured by the first image-capture portion 11
Brightness value is more than Second Threshold and when second processing portion 30 is determined as that sunshading board is not used in driver, it means that driver
Sunshading board is not used but drives vehicle under the stronger road environment of light, and this situation is also than relatively hazardous, thus control unit
40 send the early warning for putting down sunshading board to driver.
Therefore, vehicle according to the invention safe driving assistant system 100, also sunglasses can be used according to driver
The road environment of state and this vehicle front, given to driver put down/pack up sunshading board, so as to avoid driver in danger
Situation down train.
In addition, as Additional embodiments or alternately, the determination unit 22 of the first processing unit 20 can be with
Judge whether this vehicle is continuously in a certain specified link environment (for example, tunnel or snowfield etc.), i.e., determination unit 22 also judge by
Whether whether the average brightness value for the external environment condition image that calculating part 21 is calculated continuously less than first threshold or continue big
Scheduled time slot (for example, 3 minutes) is reached in Second Threshold.Also, when determination unit 22 is judged to being captured by the first image-capture portion 11
External environment condition image average brightness value continuously less than first threshold up to scheduled time slot and when second processing portion 30 is determined as
When driver has worn sunglasses or has used sunshading board, it means that driver has worn sunglasses or used sunshading board to exist
Vehicle is driven under the road environment of dark and continue for a period of time, thus control unit 40 sends to driver and removed too
Positive mirror or the early warning for packing up sunshading board.And for example, when determination unit 22 is determined as the outside that is captured by the first image-capture portion 11
The average brightness value of ambient image is persistently more than Second Threshold up to scheduled time slot and when second processing portion 30 is determined as driver
When not wearing sunglasses or unused sunshading board, it means that driver does not wear sunglasses or unused sunshading board but in light
Vehicle is driven under stronger road environment and continue for a period of time, thus control unit 40 sends to driver and wears sunglasses
Or put down the early warning of sunshading board.The length of scheduled time slot, such as several seconds can be set as the case may be to several minutes.With
This mode, the early warning in particular cases excessively continually given early warning at some or give mistake can be avoided,
For example, outside road of the vehicle continuously across short intervals between a series of short culvert or several sections of longer tunnels, car
By short-range tree shade region or short-range light area etc. on road.
In the case, for instance, it is preferred that as shown in Fig. 2 determination unit 22 can include timer 221, for calculate by
First image-capture portion 11 capture external environment condition image average brightness value continuously less than first threshold duration or hold
The continuous duration more than Second Threshold.For example, when determination unit 22 is determined as that the average brightness value of external environment condition image is less than the
During one threshold value (the road light of this vehicle front is relatively dark), now timer 221 is triggered to start to calculate external rings
For the average brightness value of border image continuously less than the duration of first threshold, i.e. driver is descending in the road environment of dark
The duration sailed, and afterwards when determination unit 22 is determined as that the average brightness value of external environment condition image is not less than first threshold
When, timer 221 is reset, such as is recovered to original state or clearing.If by timer 221 is calculating, external rings
The average brightness value of border image is more than the scheduled time continuously less than the duration of first threshold and second processing portion 30 is determined as
When driver has worn sunglasses or used sunshading board, control unit 40 will be sent to driver to be removed sunglasses or packs up sunshade
The early warning of plate.
For another example, when determination unit 22 is determined as that the average brightness value of external environment condition image is more than Second Threshold (i.e. before this vehicle
The road light of side is relatively bright) when, now, timer 221 is also triggered to start to calculate the average bright of external environment condition image
Angle value be more than Second Threshold duration, i.e. driver in the duration of the brighter road environment downward driving of light, and
Afterwards when determination unit 22 is determined as that the average brightness value of external environment condition image is not more than Second Threshold, timer 221 is by again
Set, such as recover to original state or clearing.If the external environment condition image captured by the first image-capture portion 11 is averaged
Duration of the brightness value persistently more than Second Threshold is more than scheduled time slot but driver is still without wearing sunglasses or use
Sunshading board.Thus, control unit 40 will be more than scheduled time slot in the duration calculated by timer 221 and second processing portion 30 is sentenced
When being set to driver and not wearing sunglasses or unused sunshading board, sent to driver and wear sunglasses or put down the pre- of sunshading board
Alert prompting.
Therefore, according to the safe driving of vehicle accessory system 100 of the first embodiment of the present invention, can be according to driver
The no state worn sunglasses or used sunshading board and driver certain specified link environment down train it is lasting when
Between ,/remove sunglasses, put down/is given and worn to driver and packs up the early warning of sunshading board, so as to avoid driver in danger
Situation down train.
