2) digital video signal is carried out with cutting, exports the LCD screen resolution identical video signal with display module, depending on
Frequency signal is used as bottom layer image by surface view process；
3) the optimal direction of traffic of vehicle is passed through sub- view Overlapping display on bottom layer image, realize vehicle is optimal
Direction of traffic is added in outdoor scene night vision image.
Navigation information is superimposed upon in night vision image the present invention, thus during driving at night, driver is using night
While depending on auxiliary, could be used that navigation guide function, improve the driving convenience of human pilot have and realize process letter
Single, configuration complexity is low, low cost and other advantages.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood to this
Bright, but they do not constitute restriction to the present invention.
As shown in figure 1, the night vision system that the present invention realizes vehicle-mounted real scene navigation includes
Navigation module, for obtain navigation the current origin of vehicle to objective optimal direction of traffic, and send to
Image overlay module.
Navigation module includes locating module and mapping module, and described locating module is GPS location message recipient, for reality
When receive navigation vehicle current geographic position information；Described mapping module is used for receiving and storing the title letter of objective
Breath, and the described current geographic position information received by with described locating module, as origin, obtains described origin to institute
State the optimal navigation way of objective, and then obtain the navigation current origin of vehicle to the optimal driving side of described objective
To.
Night vision processing module, for gathering night vision image and it being carried out process and obtain outdoor scene night vision image, sends to figure
As laminating module.
Night vision processing module includes night vision module and outdoor scene processing module, and described night vision module includes night vision cam and night
Depending on ECU, night vision cam collection night vision image is sent to night vision ECU, and night vision ECU generates night vision image information and sends to real place
Reason module；Described outdoor scene processing module is used for comparing night vision image information according to presetting outdoor scene acquisition parameter, and acquisition is found a view
In the range of outdoor scene night vision image.Wherein, described outdoor scene acquisition parameter includes gathering far point, acquisition angles, gathers direction, low coverage
Point value and long distance point value；Described collection far point is navigated the current location of vehicle described in being；Described collection direction is institute
State the current direction of traffic being navigated vehicle, wherein, acquisition angles refer to the angle of pitch of described real scene navigation acquisition module.
Image overlay module, can be the MCU within vehicle-mounted MP5, for the optimal direction of traffic of vehicle is added to reality
In scape night vision image, and send to display module.
The process that the optimal direction of traffic of vehicle is added in outdoor scene night vision image is：
