Description
Technical field
The utility model is related to a kind of vehicle-mounted security alarm devices, more particularly to a kind of based on the non-of computer vision technique
Contact fatigue driving monitoring device belongs to automotive internal accessory technical field.
Background technology
As the number of domestic automobile ownership and driver constantly increase a few days ago, fatigue driving phenomenon takes place frequently,
According to traffic accident data statistics over the years, about 50% traffic accident is related with fatigue driving.
Fatigue driving is mainly manifested in driver in continuous driving for a long time, generates the mistake of physiological function and mental function
Tune or driver's poor sleeping quality or deficiency, long-duration driving vehicle generate attention, feeling, consciousness, thinking, judgement, meaning
The decline of the aspects ability such as will, decision and movement.When driver fatigue, it may appear that blurred vision aches all over, acts and stay
Plate, trick swell or have energy not concentrate, is slow in reacting, think deeply phenomena such as not thorough, rhembasmus, anxiety, irritability.If still
Vehicle is driven reluctantly, then may lead to traffic accident.
Invention content
In order to solve the problems in above-mentioned background technology, the utility model provides a kind of with fatigue monitoring function
Room mirror can effectively prevent the traffic accident caused by fatigue driving.
Technical solution used by the invention for solving the technical problem is：A kind of car with fatigue driving monitoring function
Rearview mirror, including hemispherical infrared pick-up head, microprocessor, main body cover and alarm.
Wherein hemispherical infrared camera acquires driver's facial information, and collected picture is real-time transmitted to micro- place
Device is managed, the graphics processing unit in microprocessor carries out dissection process to picture, is finally carried out using real-time driving fatigue monitoring system
Detection, to judge whether driver is in fatigue driving state.
Further, the front of main body cover is embedded with rear view mirror lens.
Further, hemispherical infrared pick-up head is connected immediately below main body cover, it can be with 360 ° of acquisition images, without adjusting
The acquisition of driver's facial information can be realized in whole door mirror angle, and has the function of the acquisition of night face information.
Further, the microprocessor is the microcontroller of model STM32F101R6.
Further, the graphics processing unit model ADSP-TS201S.
Further, the real-time driving fatigue monitoring system is DDS systems.
Further, microprocessor is connected with alarm, if it is decided that and result is that driver is to be in fatigue driving state,
Microprocessor can trigger the switch of alarm, and alarm sends out alarm tone by loud speaker, and the time of alarm is 10 seconds, to carry
Driver safety of waking up travels.
The utility model has the advantages that compared with prior art：Present apparatus rearview mirror original function in the car
On the basis of increase hemispherical infrared pick-up head, microprocessor, alarm, hemispherical infrared pick-up head acquires driver's face
Portion's information, and collected picture is real-time transmitted to microprocessor, microprocessor carries out dissection process to picture, finally uses
Whether real-time driving fatigue monitoring system DDS judgements driver is in fatigue driving state.If it is determined that result, which is driver, is in fatigue
Driving condition, microprocessor can send alarm signal to loud speaker, and loud speaker sends out alarm in 10 seconds, reminds driver safety
It drives, and then realizes room mirror fatigue driving monitoring function.
Further, which uses computer vision technique, and not with direct body contact, hemispherical is infrared
Adopting for driver's facial information can be realized without artificially adjusting the angle with information in 360 ° of acquisition driver's cabins in line camera
Collection, and can be worked normally at night, it can effectively prevent the traffic accident caused by fatigue driving.Do not influencing room mirror
Under the premise of normal use, multi-purpose content takes full advantage of interior space.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.The identical attached drawing of wherein identical parts
Label indicates.It should be noted that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to
It is the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and "outside" are referred respectively to towards or away from particular elements geometry
The direction at center.
A kind of room mirror with fatigue driving detection function, as shown in Figure 1, including holder 1 and main body cover 4
And hemispherical infrared pick-up head 7, hemispherical infrared pick-up head 7 are installed on immediately below main body cover 4, main body cover 4 is just
Surface is embedded with the eyeglass 2 of room mirror, the power supply indicator 5 and switch of 2 right side arrangement fatigue driving monitoring device of eyeglass
Button 6, left side are the loud speakers 3 of alarm, three altogether, are formed a line, loud speaker 3, power supply indicator 5, hemispherical are infrared
Line camera 7 is all connected with microprocessor 8.
Holder 1 and main body cover 4, can be by adjusting the angle tune of main body cover 4 by pin connection combined with Figure 1 and Figure 2,
The angle of whole rear view mirror lens 2, for microprocessor package outside the main body inside shell 4, loud speaker 3 is in a 4 positive left side of main body cover
Side, forms a line by three altogether, when real-time driving fatigue monitoring system detects that driver is in fatigue driving state, microprocessor
