Brief description
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated：
Fig. 1 is the structural representation of the in-car arrangement of device of the elimination automobile A-column blind area of the present invention.
Photographic head, the left display of 5-, 6- after before the left front photographic head of in figure 1-, the left back photographic head of 2-, 3- are right, photographic head, 4- are right
Right display, 7- image adjustment system, 8- central processing unit.
Specific embodiment
With reference to Fig. 1, a kind of device of elimination of present invention automobile A-column blind area, including central processing unit 8 and respectively with centre
The connected outdoor scene harvester of reason device 8, display device, image adjustment system 7；Display device includes left display 5 and right display
Device 6, is respectively arranged on vehicle right and left A post inner surface；Central processing unit 8, outdoor scene harvester, display device may be contained within car
Interior；Outdoor scene harvester includes two groups of photographic head groups, and one group of photographic head group includes left front photographic head 1 and left back photographic head 2, another
Group photographic head group includes photographic head 4 after photographic head 3 and the right side before the right side, and central processing unit 8 is also connected with image adjustment system 7 simultaneously
Connect.Left front photographic head 1 is used for shooting the blind area outdoor scene at automobile left side A post rear, and what the left back photographic head 2 of cooperation absorbed comprises left side
The image information of A post inner surface, central processing unit 8 can calculate the accurate picture of left side A post rear blind area.Right side A in the same manner
Post blind area picture can also obtain.
When vehicle-periphery is in the middle of specific environment, such as rain, jolt, a series of special circumstances such as light flash,
Cause that the information processing capacity of central processing unit 8 is excessive or fluctuation is excessive, image adjustment system 7 can be by adjusting the adopting of photographic head
Mode set or the processing mode of central processing unit 8, such as switch to white-black pattern, switch to low-resolution mode to reduce flow of information
The modes such as amount are so that the picture shown by display device is maintained at the state of no delay or less delayed.Wherein triggering image is adjusted
Whole system 7 be adjusted action method can include following two, the first be image adjustment system 7 borrow after photographic head,
The camera picture of photographic head after Real-time Collection, by actual to the display device display picture in rear shooting camera picture and surrounding
Picture is contrasted, and determines whether coherent image, thus judging delay situation, when postponing higher, triggering image adjustment system
System 7 is adjusted action；Second is the operating state of image adjustment system 7 monitor in real time central processing unit 8, in detecting
The process intensity peak of central processor 8 is in higher position or process strength fluctuation variance is larger, then triggering image adjustment system
System 7 is adjusted action.
The present invention can also arrange Visual Tracking System, including vision camera and visual processes portion, visual processes part
It is not connected with vision camera and central processing unit 8.Visual Tracking System reads visual angle, height of sighting line and the concern of driver
The information such as display device period, when driver does not observe to display device, now control at central processing unit 8 suitably reduction
Reason intensity；When visual angle or the height of sighting line change of driver, the image content shown by display device can be adjusted in time.
Conventional vehicle, its A post inner surface is in generally irregularly shaped, the present invention can by the shape of display be designed to
Its inner surface matches, and is easy to laminating and installs, save space.Meanwhile, erose surface easily causes distortion, joins
A standby development adjustment portion, the moment adjusts the picture shown by display device, it is to avoid the occurrence of distortion.
In order to the more preferable imaging surface angle controlling each photographic head, it is each equipped with viewing angle control in each photographic head bottom
Device, viewing angle control device is controlled by central processing unit 8, central processing unit 8 can comprehensive various information, optimize the shooting of each photographic head
Angle.
In order to accelerate display speed and reduce the instantaneous treating capacity of central processing unit 8, the present invention can also arrange a data and delay
Flushing device, the shooting face of photographic head is very big, can take in image information more in advance in advance, and information is stored in advance data and delay
In flushing device, central processing unit 8 then can carry out bulk processing when peak value is relatively low to prestored information, increases the accurate of later stage process
Property and promptness.
