Abstract
The utility model discloses an anti-dazzling vehicle-mounted night vision system, comprising a controller performing data exchange with a camera, a display, an automobile signal transmission end and a memory, and a system power supply supplying electric power to the night vision system, wherein the camera is an infrared camera with an optical filter located at the position of the lens of the camera. When an automobile meets a vehicle and is in a state of high light, the anti-dazzling vehicle-mounted night vision system can still work normally and gives an early alarm for the driver, thereby avoiding traffic accidents and increasing vehicle traveling safety.
Description
Technical field
The utility model relates to automatic night vision system, is specifically related to a kind of anti-dazzle on-vehicle night vision system.
Background technology
Having investigation to show that 60% traffic accident all occurs in the situation of night and bad weather, mainly is because the sight line of driving is poor, and car speed is higher to be caused.Especially travel at the road that does not have street lamp night, be subjected to the restriction of headlight for vehicles irradiation distance, driving at night has potential safety hazard.What automatic night vision system mainly used at present is thermal imaging, is also referred to as the infrared imaging technology.Its principle is exactly: any object all can distribute heat, and the heat that the object of different temperatures distributes is different.Human, animal is compared the heat that distributes with the vehicle that travels and wants many with surrounding environment.Night vision system just can be collected these information, then is transformed into visual image, and the object that does not originally see at night clearly is presented at the moment, increases the fail safe of driving at night.The on-vehicle night vision system has brought the great sense of security to the driver.Test factually and show, general automobile etc. can only shine about 100m, and night vision system can be seen the traffic information beyond the 450m at least, and power consumption but is 1/4th of headlamp.If there is an adult people in running car the place ahead, a clear-eyed driver can see him in the 88m place apart from him with dipped headlights, can reach 164m with high beam, and can outside 458m, find the pedestrian in the place ahead with night vision system, although it is at screen little luminous point just; On the other hand, even open the demonstration that automobile headlamp does not affect image yet.In addition, night vision system is round-the-clock electronic eyes, and the object on sleet, thick fog weather highway and all of roadside also can both have a panoramic view, and greatly improve the fail safe of running car.But there is an insoluble problem in the night vision system of using at present always, and namely when vehicle meeting, the large lantern festival of sending a car produces dazzle, and night vision system is made a big impact.
The utility model content
Technical problem to be solved in the utility model is to realize a kind ofly can effectively preventing the night vision system that the meeting dazzle impacts the on-vehicle night vision system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of anti-dazzle on-vehicle night vision system, be provided with the controller that carries out respectively exchanges data with camera, display, vehicle signal transmission ends and memory, and be the system power supply of system power supply, described camera is the infrared pick-up head that the camera lens place is provided with filter.
System also is provided with illuminance transducer from current light intensity status signals to controller that input.
The digital video signal of described camera collection is processed into the parallel digital video signal via conversion chip with vision signal and is delivered to controller again, and described controller is processed the image that collects by being undertaken by conversion chip sending after D/A changes and is delivered to display.
Described controller adopts chip ADSP-BF561, and the conversion chip of described camera is the chip DS92LV1212 that unstrings, and the conversion chip of described display is D/A conversion chip ADV7179.
The utility model has the advantage of this system so that vehicle under the high light states such as meeting, the on-vehicle night vision system still can work, and is the human pilot early warning, reduces the generation of traffic accident, improves vehicle travel safety.
Description of drawings
The below makes brief description to the content of every width of cloth accompanying drawing expression in the utility model specification and the mark among the figure:
Fig. 1 is anti-dazzle on-vehicle night vision circuit system block diagram;
Mark among the above-mentioned figure is: 1, controller; 2, camera; 3, display; 4, conversion chip; 5, vehicle signal transmission ends; 6, memory; 7, illuminance transducer; 8, system power supply.
Embodiment
Referring to Fig. 1 as can be known, native system shines vehicle front by infrared light compensating lamp, detect by 2 pairs of vehicle front images of infrared camera, and the image data transmission after will detecting is processed by controller 1 to controller 1.Controller 1 is chip ADSP-BF561, the picture signal that camera 2 gathers transfers to controller 1 via conversion chip 4, this conversion chip 4 is for unstringing chip DS92LV1212, because the data that camera 2 is sent here are differential digital vision signals, so before the differential digital vision signal is sent to controller 1, by the chip DS92LV1212 that unstrings vision signal is processed into the parallel digital video signal first and gives again controller 1; The signal of processing via controller 1 exports display 3 demonstrations to via conversion chip 4, this conversion chip 4 is D/A conversion chip ADV7179, after controller 1 is converted to analog video signal by this chip with digital video signal with the image processing that collects, delivering to display 3 shows, vehicle signal transmission ends 5 is connected with controller 1, can and vehicle between carry out data transaction, system also is provided with the memory 6 that is connected with controller 1, and is the system power supply 8 of system power supply.
Also be that system possesses the anti-dazzle function for making, camera 2 adopts the camera lens place to be provided with the infrared pick-up head of filter, by taking filter, white light and high light is filtered out, simultaneity factor also is provided with to the illuminance transducer 7 of the current light intensity status signals of controller 1 input, with the collection of crossing ambient lighting, controller 1 adopts different algorithms according to this ambient lighting signal to the night vision signal pattern, be that illumination is stronger, algorithm for image enhancement, thus reach the effect of night vision system, avoid the impact of dazzle.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
