Description
【Technical field】
The present invention relates to field of automobile safety, more particularly to a kind of illuminance compensation of drive recorder collision early warning system
System and method for.
【Background technology】
The collision early warning system of drive recorder mainly identifies the position of front truck so as to reach by the image photographed
To the prompting to driver, but under night mode or overline bridge masking environment, because the limitation of ambient causes anticollision
Early warning system can not successfully judge the position of front truck to remind driver, therefore, how prevent the change of light from causing to prevent
Collision warning systems failure turn into one it is to be solved the problem of.
【The content of the invention】
For the above situation, it is an object of the invention to provide a kind of illumination of drive recorder collision early warning system benefit
System and method for is repaid, when surrounding environment is dark causes drive recorder shooting image unintelligible, increase shooting brightness, improves figure
Image sharpness, collision early warning system is avoided to fail.
To reach above-mentioned purpose, the present invention provides a kind of illuminance compensation system of drive recorder collision early warning system,
Including a drive recorder, the drive recorder has anticollision warning function, and the drive recorder includes：
One light acquisition module, in-car real-time illumination is measured in running car；
One control module, the specified illumination and in-car outer illumination needed for storage anticollision warning function are poor, connect the light
Line acquisition module, the real-time illumination that the light acquisition module measures is received, judge that the real-time illumination is with the illumination difference sum
It is no to reach the specified illumination, required compensation illumination is calculated if not up to, and send a compensation to the compensating module and order；
One compensating module, there is a light emitting source, connect the control module, a benefit is sent to front side according to the compensation order
Repay light.
Especially, the drive recorder also includes：
One photographing module, the control module is connected, travelling image is shot after automobile starting, the travelling image is sent to
The control module is to judge whether to collide with other vehicles；
One alarm module, connect the control module, sent when the control module, which determines, to collide alarm with
Remind driver.
Especially, the compensation light is black light.
The present invention also provides a kind of illuminance compensation method of drive recorder collision early warning system, for compensating its anti-collision
The deficiency of early warning system illumination is hit, is comprised the following steps：
(A) specified illumination required during collision early warning system normal work is obtained；
(B) the in-car outer illumination of measurement in advance and to calculate illumination poor；
(C) in-car real-time illumination is measured during running car；
(D) total illumination outside car is calculated with the illumination difference outside the in-car by the real-time illumination of the in-car；
(E) judge whether the total illumination outside car reaches the specified illumination；
(F) judged result is no that then drive recorder sends a compensation light to outside car, total illumination is reached specified photograph
Degree.
Compared to prior art, the illuminance compensation System and method for of drive recorder collision early warning system of the invention is pre-
It is poor first to measure the outer illumination of in-car, and real-time illumination is to obtain total illumination outside real-time car in monitoring car in running car, in vapour
When car environmental change causes the outer total illumination change of car and does not reach the specified illumination of collision early warning system, send compensation light with
The deficiency of illumination is compensated, enables collision early warning system normal work.
【Brief description of the drawings】
Fig. 1 is the structure chart of the embodiment of illuminance compensation system one of the drive recorder collision early warning system of the present invention；
Fig. 2 is the flow chart of the embodiment of illuminance compensation method one of the drive recorder collision early warning system of the present invention.
【Embodiment】
Refer to shown in Fig. 1, an embodiment of the illuminance compensation system of drive recorder collision early warning system of the present invention,
Including drive recorder, the drive recorder has anticollision warning function, it include light acquisition module 1, control module 2,
Compensating module 3, photographing module 4 and alarm module 5.The light acquisition module 1 and the photographing module 4 connect the control module respectively
2, the control module 2 connects the compensating module 3 and the alarm module 5 respectively.
The light acquisition module 1 measures the real-time illumination of in-car.Anticollision early warning work(is stored in the control module 2 in advance
Specified illumination needed for energy, further, since light from in-car to car outside reflect when passing through windshield, cause to shine outside in-car
Degree is different, and therefore, it is poor also to store the outer illumination of in-car for measuring and being calculated in advance in the control module 2, the control module 2
The real-time illumination that the light acquisition module 1 measures is received, the real-time illumination is added to obtain total illumination outside car with illumination difference,
Judge whether the total illumination reaches the specified illumination.When the total illumination is less than the specified illumination, the control module 2 calculates institute
The compensation illumination needed, and send a compensation to the compensating module 3 and order, it should be noted that the compensation illumination needs when calculating
It is additionally poor plus the outer illumination of the in-car.The compensating module 3 sends a compensation light according to the compensation order to front side,
In the present embodiment, the compensation light is black light, i.e., below wavelength 400nm or more than 760nm, to avoid compensating light to driving
The person of sailing drives and impacted.Therefore, when car steering environment changes, real-time illumination is changed, and compensating module is sent
Compensation light also change, the outer total illumination of the car is reached specified illumination all the time, so that the collision early warning system
All the time normal operation, the photographing module 4 shooting driving video recording, the control module 2 judge whether to send out according to driving video recording
Raw collision, come if there is vehicle to hit, the alarm module 5 sends alarm to remind driver.
Refer to shown in Fig. 2, an embodiment of the illuminance compensation method of drive recorder collision early warning system of the present invention,
For compensating the deficiency of its collision early warning system illumination, comprise the following steps：
S10：Required specified illumination during by consulting the operation instruction of collision early warning system to obtain its normal work.
S20：The illumination outside synchronization in-car is measured in advance, to calculate by windshield is to anaclasis institute
Illumination outside caused in-car is poor.
S30：In-car real-time illumination is measured during running car.
S40：The real-time illumination is added with illumination difference, obtains the outer total illumination of car now.
S50：Whether the outer total illumination of the car of judgement now reaches the specified illumination needed for collision early warning system.
S60：Drive recorder launches a branch of compensation light to outside car, the outer total illumination of car is reached specified illumination.
S70：The collision early warning system can identify the position of surrounding vehicles by clearly image, so as to play vehicle
Hit the effect that driver is reminded when coming.
Above in conjunction with accompanying drawing to the present invention embodiment and embodiment elaborate, but can not with restriction
The scope of the present invention, the impartial modification and transformation made in scope of the present invention patent, should all belong to patent of the present invention
In the range of.
