Abstract
The invention relates to the field of safe automobile driving, in particular to an anti-dazzling rearview mirror. The anti-dazzling rearview mirror comprises an optical sensor for detecting a dazzling light source projected to the rearview mirror and saving an image projected to the rearview mirror at the present, and an image processing unit which is used for receiving the image saved by the optical sensor, reducing the brightness of the dazzling light source in the image, and transmitting the processed image to the rearview mirror. The anti-dazzling rearview mirror disclosed by the invention can reduce the brightness of the dazzling light source projected into the image in the rearview mirror through the image processing unit, thus relieving or eliminating halation or dazzling of a driver.
Description
Technical field
The present invention relates to vehicle security drive field, particularly a kind of anti-dazzle driving mirror.
Background technology
Self-propelled vehicle throws light on head lamp or head lamp usually under the following two kinds situation, and a kind of situation is when environment visbility is poor around, especially in the dark for vehicle illuminates the road in front; Another kind of situation reminds the vehicle on other tracks, so that other chaufeurs can see this self-propelled vehicle.Head lamp in use should premised on not allowing chaufeur or other pedestrians feel to have a dizzy spell.But, sometimes head lamp is for can be very twinkling oncoming motor vehicle driver, such as lorry when headlamp lighting degree does not regulate (as there is no to be switched to passing light from country beam in time, especially when right-hand corner), the light of country beam is because of rain, snow or nebula cause astigmatism etc., dazzling in short-term that this head lamp causes more easily causes traffic accident, chaufeur is caused to be difficult to notice the vehicle on other tracks because dazzle, particularly the elderly more easily produces and dazzles the eyes or dazzling sensation, and the elderly is feeling that the dazzling rear time needing more to grow just can return to normal vision.
Publication number is that the application for a patent for invention of DE102012205429 discloses one " reduce engine motor-car causes the system of dazzling the eyes to chaufeur ", this system comprises an image calculation unit and an image enhancing unit, reduces the twinkling degree of dazzling the eyes light source by the brightness improving surrounding environment.
Summary of the invention
The object of the present invention is to provide a kind of anti-dazzle driving mirror, it reduces in image the brightness dazzling the eyes light source by graphics processing unit.
In view of this, the invention provides a kind of anti-dazzle driving mirror, it comprises an optical pickocff, projects dazzling the eyes light source and storing the current image projected on back mirror on back mirror for detecting; With a graphics processing unit, receive the described image that described optical pickocff stores, and reduce the brightness dazzling the eyes light source in this image, then the image after process is sent to described back mirror.
According to one embodiment of present invention, described optical pickocff can be a camera or a photographic camera.
According to still another embodiment of the invention, described graphics processing unit is divided into different subregions described image, according to dazzling the eyes light source place subregion and the luminance difference of subregion around it, reduces the brightness dazzling the eyes light source place subregion.
As can be seen here, anti-dazzle driving mirror of the present invention can be reduced by graphics processing unit dazzles the eyes light-source brightness in the image projected in back mirror, thus reduces or eliminates dazzling to chaufeur.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in more detail by the following examples.
A kind of anti-dazzle driving mirror, it comprises an optical pickocff, projects dazzling the eyes light source and storing the current image projected on back mirror on back mirror for detecting; With a graphics processing unit, receive the described image that described optical pickocff stores, and reduce the brightness dazzling the eyes light source in this image, then the image after process is sent to described back mirror.
Described optical pickocff can be such as a camera or a photographic camera, a branch of or multi beam for detecting another car projected on this car back mirror dazzles light source or dazzle the eyes light source, the head lamp etc. of the head lamp of such as rear car, the taillight of front truck or oncoming self-propelled vehicle.Here back mirror comprises inside rear-view mirror and/or outside rear-view mirror.Optical pickocff to store while the current image projected on back mirror can also assisted Extraction for the relevant information of the light source position that dazzles, namely can know and dazzle the eyes light source position in the images and approximate range.Optical pickocff is this width image and dazzle the eyes the location information etc. of light source to send to graphics processing unit afterwards.
After graphics processing unit receives the image of optical pickocff transmission, to dazzling the eyes the brightness of light source to process in this image, concrete treating process is as follows:
This image is divided into different subregions, and size and the brightness of every sub regions are not quite similar, such as, have highlight regions and low bright area.Dazzle the eyes light source can be in a sub regions or be divided in a few sub regions all can.Graphics processing unit is according to dazzling the eyes light source place subregion and the luminance difference degree of subregion around it, reduce the brightness dazzling the eyes light source place subregion, make to dazzle the eyes the luminance difference of light source place subregion and surrounding subregion not obvious, thus reduce or eliminate to dazzle light source to chaufeur cause dazzle.Dazzle the eyes the twinkling degree of light source higher, graphics processing unit dazzles the eyes the brightness of light source place subregion just to reduce lower to this.Preferably, the brightness measurer that one special can be provided, can obtain accurately like this dazzling the eyes the brightness value of light source place subregion and the brightness value of surrounding subregion, brightness value difference according to the two reduces the brightness value of dazzling the eyes light source place subregion quantitatively, makes it consistent with the brightness value of surrounding subregion or close.
In addition, image after graphics processing unit process is except sending to back mirror, thus it is upper outside to be directly presented at back mirror, can also projects on new line display (HeadUpDisplay) of pilot's line of vision scope, typically project on front windshield.New line technique of display is well known to those skilled in the art, repeats no more here.
The present invention relates to vehicle security drive field, particularly a kind of anti-dazzle driving mirror, it comprises an optical pickocff, projects dazzling the eyes light source and storing the current image projected on back mirror on back mirror for detecting; With a graphics processing unit, receive the described image that described optical pickocff stores, and reduce the brightness dazzling the eyes light source in this image, then the image after process is sent to described back mirror.Anti-dazzle driving mirror of the present invention can be reduced by graphics processing unit dazzles the eyes light-source brightness in the image projected in back mirror, thus reduces or eliminates dazzling or dazzling the eyes chaufeur.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
