During operation, the infrared camera acquires facial images of a driver in real time; the processing unit performs analysis on human eyes of the facial images, judging opening and closing degrees of the human eyes, controlling the motor to drive the shaft of the shading plate to rotate to open the shading plate when detecting that both the closing degree and the light intensity sensor reach a threshold; realizing real-time following control of corners of the shading plate and positions of the eyes. By the arrangement, manual adjusting of the shading plate by the driver is omitted, so that hands of the driver can be attached to a steering wheel all the time, and positive significance is achieved to safe driving; meanwhile, size of descending of the shading plate can be accurately adjusted, and impact on view of the driver can be reduced as much as possible.
Description
Technical field
The present invention relates to a kind of anti-dazzle device, particularly relate to a kind of based on human eye and shade video identification, self-adjustable anti-dazzle device.Relate to the window of Patent classificating number B60 general vehicle B60J vehicle, Windshield, on-fixed roof, door or allied equipment; The moveable external jacket B60J3/00 being specially adapted for vehicle be combined with window or Windshield anti-dazzle to equip B60J3/02 position adjustable.
Background technology
Along with the intellectuality of auto trade, present automobile various functions also trends towards Based Intelligent Control, automotive light-shading board is no exception, also some automatic or semi-automatic modes have been there are, but the people of different height is to the area requirements difference that is in the light of anti-dazzle device, may occur having tunnel vision for any chaufeur of height like this, there is potential safety hazard.Have patented invention variable area anti-dazzle device at present, but want chaufeur manually to complete.If travelled by day, light change is not obvious, and chaufeur can manual complete operation at one's leisure.But, when night running, if run into suddenly the dazzling distance light of opponent vehicle, cause chaufeur temporary blindness and ambient environment cannot be seen clearly, great potential safety hazard can be caused.
People, when prominent chance light strengthens, can close degree by subconscious adjustment eyes, and relative in twenty-twenty vision situation, closed eyes profile variations is comparatively large, for the human eye state identification based on video provides the foundation.Technical scheme for eye recognition in prior art reaches its maturity, and has started to enter actual operational phase.If: document " based on the eye recognition of infrared difference frequency and the research of tracking " disclosed in " agricultural equipment and Vehicle Engineering " the 8th phase in 2010 is exactly the example that maturation is applied in prior art, by the hardware being core with infrared camera and DSP, can complete the human eye closure state identification of suitable precision, the human eye of whole day closes recognition success rate all more than 80%.
Through a large amount of Germicidal efficacy, when chaufeur uses automotive sunshade panel, due to blocking of sun shield, can form comparatively significantly shade on face, existing video recognition algorithms can identify the shade that this type of area is comparatively large, demarcation line is regular accurately.As: done detailed describing to Gray Image Edge Detection Method in " the rim detection research based on gray level image " Northwestern Polytechnical University's paper, those skilled in the art can complete Shadow recognition completely according to the rudimentary knowledge in this paper and video identification field.
Summary of the invention
The present invention is directed to above problem, develop a kind of anti-dazzle device based on video identification, comprising: the motor of the axle that infrared camera, light intensity inductor, processing unit, driving are flexibly connected with anti-dazzle device.
Intelligent system is by pressing switch to open or closing on steering handwheel.During system works, infrared camera Real-time Obtaining steerman face video image; Described processing unit carries out human eye analysis to the face-image obtained, and judges the degree of human eye opening and closing, when detect human eye close degree and described light intensity inductor all reach threshold value time, the motor described in control drives the rotation of anti-dazzle device axle, opens anti-dazzle device; And then, the light and shade cut-off rule position that described processing unit Real-Time Monitoring anti-dazzle device is formed at face, critical spot below eyes is positioned at when monitoring this cut-off rule, and eyes closed degree is when returning to normal condition, then stop the rotation of anti-dazzle device, realize the real-time servo antrol of anti-dazzle device corner and eye position.
Further, when intense light source disappears, anti-dazzle device of the present invention also can be packed up automatically.When intense light source disappears, the intensity signal that light intensity inductor obtains drops to certain threshold value, and the driving stepper motor anti-dazzle device axle described in processing unit controls rotates, and closes anti-dazzle device.
This device eliminates the action of steerman manual regulation anti-dazzle device, allows the both hands not departure direction dish all the time of steerman, has positive meaning for safe driving; This device amplitude that can accurately regulate anti-dazzle device to fall simultaneously, to ensure, under the prerequisite of blocking high light, to reduce the impact on driver's seat as far as possible.Wherein, adopting infrared image can ensure that anti-dazzle device is when running into the accent light of subtend car night, also can stablize the eye image obtaining steerman.
Further, consider control panel, comprise video analysis and may produce fault or arithmetical error in certain extreme cases, cause anti-dazzle device to lose efficacy or the falling of mistake, pretend as preferred embodiment, described anti-dazzle device is flexibly connected with described axle by self-locking mechanism.
Described self-locking mechanism comprises: at least 2 groups are arranged on multiple groove, the rings be fixed on anti-dazzle device being arranged in annular on axle, and this ring coordinates with axle, and is fixed on the hole on anti-dazzle device.Described inside, hole is provided with from lock ball, is provided with spring between this ball and bottom surface, hole; From lock ball under the action of the spring with described groove fit, complete self-locking, make anti-dazzle device and axle keep special angle, can ensure to realize position self-locking after hand rotation anti-dazzle device.
Consider, motor speed is too high relative to the spin velocity of sun shield, makes anti-dazzle device adjustment of rotational speed to appropriate speed by reducing gear.Preferably, described motor has output gear; Described axle is coordinated with the output gear of motor by reducing gear.
Preferably, described motor is brake stepping motor, is convenient to accurately control the anti-dazzle device anglec of rotation, can be two-way locked during power-off simultaneously.After locked, anti-dazzle device will be fixed on correct position relatively, prevents the reasons such as uneven road surface situation or acceleration/accel from causing anti-dazzle device to rotate, and reduces shaded effect.
Owing to have employed technique scheme, anti-dazzle device based on video identification provided by the invention, there is following advantage: utilize infrared face capturing technology and light intensity induction system, realize the anti-dazzle device anglec of rotation adapted from different height chaufeur and radiation direction through the process of processing unit.Can also hand rotation anti-dazzle device when circuit goes wrong or when chaufeur does not think Based Intelligent Control, safety and reliability is high.The intelligent height of whole service mechanism, structure is simple simultaneously, good economy performance.
