Abstract
The Vehicular night vision system based on image mosaic and image co-registration that the present invention relates to a kind of, including two or more visible light cameras, two or more thermal imaging cameras, Visual image processing module, graphic images processing module, image co-registration module and display device.The present invention is spliced by the image absorbed to multiple same type video cameras, increases the field range of Vehicular night vision system；And merging by visible images and graphic images, the information for making final image be included is more abundant, more meets the actual conditions of target scene.
Description
Technical field
The present invention relates to vehicle drive control technology field more particularly to a kind of vehicles based on image mosaic and image co-registration
Carry night vision system.
Background technique
With popularizing for automobile, the safety of automobile also more seems important, especially probability of the night since accident occurs
Increase, therefore the safety that automobile at night drives is more important.Vehicular night vision system is exactly to improve automobile at night and drive
Safety and be mounted on the equipment on automobile, it can obtain the video information of vehicle front scene, and be shown in display device
On.But for existing Vehicular night vision system due to the limitation of video camera, the visual field is relatively narrow, makes driver not it is observed that wider range
Scene.
In addition, the image of visible light camera shooting is reflected image, radio-frequency component is more, and field can be reflected under certain illumination
The detailed information of scape, but cannot reflect road conditions under inclement weather conditions, especially under the weather conditions such as mist, haze, snow, rainy more
Add obvious；The image of thermal imaging camera shooting is radiation image, can detect target, but its resolution ratio through mist, haze etc.
Low, details, contrast are bad, cannot reflect true scene.Therefore, the exclusive use of these two types of video cameras cannot all be allowed
The satisfied visual effect of people.
Summary of the invention
The purpose of the present invention is the image by acquiring to multiple video cameras splice and will be seen that light video camera and heat
The image of imaging camera machine shooting is merged, to obtain the preferable image of wider field of view, visual effect.
In order to achieve the above objectives, the present invention provides a kind of Vehicular night vision system based on image mosaic and image co-registration,
Feature be include two or more visible light cameras, two or more thermal imaging cameras, at visible images
Manage module, graphic images processing module, image co-registration module and display device, in which:
Two or more visible light cameras will be seen that light image data transmission can for obtaining visible images
Light-exposed image processing module；
Two or more thermal imaging cameras are used to obtain graphic images, and graphic images data transmission is hot
Image processing module；
Visual image processing module is for splicing received visible images, and by spliced visible light figure
As data transmission image co-registration module；
Graphic images processing module is for splicing received graphic images, and by spliced thermograph
As data transmission image co-registration module；
Image co-registration module is used to merge spliced visible images and spliced graphic images, and will
Blending image transmits display device；
Display device is for showing blending image.
Preferably, the visible light camera is CCD camera, MCCD video camera or cmos camera.
The present invention is spliced by the image absorbed to multiple same type video cameras, increases Vehicular night vision system
Field range；And merging by visible images and graphic images, the information for making final image be included is more abundant,
More meet the actual conditions of target scene.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
Specific embodiment
A kind of Vehicular night vision system based on image mosaic and image co-registration, including two or more visible image capturings
Machine, two or more thermal imaging cameras, Visual image processing module, graphic images processing module, image co-registration
Module and display device, in which: two or more visible light cameras will be seen that light figure for obtaining visible images
As data transmission Visual image processing module；Two or more thermal imaging cameras are used to obtain graphic images, and
By graphic images data transmission graphic images processing module；Visual image processing module is used for received visible light figure
As being spliced, and by spliced visible images data transmission image co-registration module；Graphic images processing module is used for
Received graphic images are spliced, and by spliced graphic images data transmission image co-registration module；Image melts
Blending image is transmitted and is shown for merging to spliced visible images and spliced graphic images by molding block
Showing device；Display device is for showing blending image.Visible light camera can be CCD camera, MCCD video camera or CMOS
Video camera.
Referring to Fig.1, the present embodiment uses two visible light cameras, two thermal imaging cameras, i.e. the first visible light is taken the photograph
Camera 11, the second visible light camera 12, the first thermal imaging camera 21, the second thermal imaging camera 22, the first visible light are taken the photograph
The visible images that camera 11, the second visible light camera 12 will acquire respectively pass to the Visual image processing being attached thereto
Module 31, the graphic images that the first thermal imaging camera 21, the second thermal imaging camera 22 will acquire respectively pass to therewith
The graphic images processing module 32 of connection, it is seen that light image processing module 31 and graphic images processing module 32 are docked respectively
The image received is spliced, and so as to obtain larger range of scene image, is then transmitted spliced image data
Image co-registration module 35, image co-registration module 35 melt spliced visible images and spliced graphic images
It closes, and blending image is transmitted into display device 40, to show blending image.Fused image can more realistically reflect vehicle
The scene in front, so that auxiliary driver drives the case where making vehicle driver preferably observe vehicle front.
Presently disclosed embodiment, for realizing or using the present invention those skilled in the art.To these embodiments
A variety of modifications or modification will be apparent for a person skilled in the art.General Principle described herein can be
In the case where not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to
Embodiment described herein, and it is to fit to the widest model consistent with principles disclosed herein and novel features
It encloses.
