Description
Technical field
The present invention relates to vehicle electric field, more particularly to a kind of Near Infrared CCD night vision auxiliary lighting system based on DSP.
Background technology
Driving information 90% during driving derives from vision, at night because illumination is not enough, the visual field is small, especially meeting when it is remote
Light lantern festival dazzles the eyes driver's generation, forms blind area, reduces the visual range of driver, have impact on the traffic safety at night.
Using the infrared night vision system of infrared imaging and image display technology, driver can be made clear in low visibility or dark
It was observed that the information of vehicle front, can also see vehicle front lighting light irradiation less than region, the pedestrian in strong time shadow, vehicle,
And alarm is sent to the dangerous situation being likely to occur.
The content of the invention
The purpose of the present invention be overcome prior art exist defect there is provided it is a kind of improve driving at night safety based on the near of DSP
Infrared CCD night vision auxiliary lighting system.
Realizing the technical scheme of the object of the invention is：Near Infrared CCD night vision auxiliary lighting system based on DSP, including it is near red
Outer ccd image sensor, DSP Processor, adaptive front lamp master controller, car body controller and near-infrared lamp, near-infrared
Road image information in front of ccd image sensor collection driving, Near Infrared CCD imaging sensor is by the mileage chart collected
As information transfer is handled to DSP Processor, DSP Processor is by the road image information transfer after processing to shining before adaptive
Lamp master controller, adaptive front lamp master controller DSP Processor is handled after road image information transfer to car body controller,
Car body controller sends distance-light switching command to control near-infrared lamp to be in high beam or dipped headlight mode of operation.
As the prioritization scheme of the present invention, line number is entered by LIN buses between DSP Processor and adaptive front lamp master controller
According to transmission.
As the prioritization scheme of the present invention, line number is entered by CAN between adaptive front lamp master controller and car body controller
According to transmission.
The present invention has positive effect：The present invention can improve the field range of nighttime driving person, as a result of near-infrared
The infrared image enhancement technology that ccd image sensor 1 is provided, detectable region is larger, strong applicability, can appointing at night
Under what photoenvironment, including head on when having strong light, driver is known the road information in front, while passing through near-infrared
Lamp carries out effective switching of lamp light mode, can effectively prevent pedestrian from producing dizziness.
Brief description of the drawings
In order that present disclosure is easier to be clearly understood, below according to specific embodiment and with reference to accompanying drawing, to the present invention
It is described in further detail, wherein：
Fig. 1 is the schematic diagram of the present invention.
Wherein, 1, Near Infrared CCD imaging sensor, 2, DSP Processor, 3, adaptive front lamp master controller, 4, car
Body controller, 5, near-infrared lamp.
Embodiment

Infrared CCD imaging sensor 1, DSP Processor 2, adaptive front lamp master controller 3, car body controller 4 and near-infrared
Road image information in front of lamp 5, the collection driving of Near Infrared CCD imaging sensor 1, Near Infrared CCD imaging sensor 1
The road image information transfer collected is handled to DSP Processor 2, DSP Processor 2 is by the road image after processing
Information transfer to adaptive front lamp master controller 3, adaptive front lamp master controller 3 DSP Processor 2 is handled after road
Road image information is transferred to car body controller, and car body controller sends distance-light switching command to control near-infrared lamp to be in high beam
Or dipped headlight mode of operation.Wherein, Near Infrared CCD imaging sensor 1 is integrated on infrared camera, the infrared light of infrared camera
The near infrared ray that source is sent actively irradiates target, and ccd image sensor 1 receives the infrared light of illuminated target reflection and then passed
It is defeated by DSP Processor 2 to be handled, DSP Processor 2 extracts pedestrian or other object informations in image, DSP processing
Device 2 can connect the display device on car, pedestrian or other object informations are output on display device, imaging clearly, can be real
When the details that show, the object being scattered on such as pedestrian, vehicle, road marking line, traffic signals and road,
Can also clearly it be shown even if athermic object.
Carried out data transmission between DSP Processor 2 and adaptive front lamp master controller 3 by LIN buses.Shone before adaptive
Carried out data transmission between lamp master controller 3 and car body controller 4 by CAN.Pass through LIN buses and CAN
Can be effective integrated with existing controller progress on vehicle, and data transmission quality is high.
Particular embodiments described above, the purpose of the present invention, technical scheme and beneficial effect are further described,
The specific embodiment that the foregoing is only the present invention is should be understood that, is not intended to limit the invention, it is all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvements done etc., should be included in protection scope of the present invention it
It is interior.
