Specific embodiment
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
In conjunction with Fig. 1 and Fig. 2, a kind of panorama driving recording and reverse image all-in-one machine provided by the invention, including proactive picture
Head group and rear camera group, wherein preceding camera group includes being installed on the preceding center camera 1 of vehicle headstock position and being installed on
Front left camera 2 and front right camera 3 on the left and right rearview mirror of vehicle, preceding center camera 1 is for obtaining vehicle front center
Preceding center image in the angular field of view of 60 degree of position, front left camera 2 is for obtaining on the left of vehicle front in 60 degree of angulars field of view
Preceding left-side images, front right camera 3 is used to obtain the preceding image right on the right side of vehicle front in 60 degree of angulars field of view；
Rear camera group includes rear center's camera 4 of vehicle tailstock position and is installed on the left and right rearview mirror of vehicle
Rear left camera 5 and rear right camera 6, rear center's camera 4 is for obtaining in the angular field of view of 60 degree of rear of vehicle center
Rear center's image, rear left camera 5 is used to obtain the rear left-side images on the left of rear of vehicle in 60 degree of angulars field of view, and the rear right side is taken the photograph
As first 6 for obtaining the preceding image right on the right side of rear of vehicle in 60 degree of angulars field of view；
Preceding center camera 1, front left camera 2, front right camera 3, rear center's camera 4, rear left camera 5 and the rear right side
Camera 6 is connected with image processing unit.In the present embodiment, preceding camera group and rear camera group use multiple spot light filling side
Formula.Solution the most popular is using infrared ray light filling on the market, but infrared ray light compensating lamp is insufficient, and light filling ability is limited
It is coarse to will cause picture.
For the image that preceding camera group and rear camera group obtain, those skilled in the art generally use hardware technology pair
Picture is spliced, and has very high requirement to hardware, therefore lead to higher cost.The present invention then uses the side of software splicing
Method splices picture in real time.Software disposably develops unlimited use, and software cost can be reduced constantly.But due to pure software
Design, the splicing effect of picture may be perfect not as hardware plan, once but the spacing of fixing camera, picture energy
Improved well.Specifically, connection scheme of the invention is as follows:
Before image processing unit obtains after center image, preceding left-side images and preceding image right, center image two before extracting
The characteristic point of side edge, preceding left-side images right side edge and preceding image right left side edge, by preceding center image left side edge
The characteristic point of characteristic point and preceding left-side images right side edge matches, and by the characteristic point and front right of preceding center image right side edge
The characteristic point of side image left side edge matches, according to mating structure by preceding center image and preceding left side image registration, and will before
Center image and preceding right side image registration, by preceding center image, preceding left-side images and the preceding right side image co-registration after registration at preceding
180 degree image；
After image processing unit obtains rear center's image, rear left-side images and rear image right, rear center's image two is extracted
The characteristic point of side edge, rear left-side images right side edge and rear image right left side edge, by rear center's image left side edge
The characteristic point of characteristic point and rear left-side images right side edge matches, and by the characteristic point of rear center's image right side edge and right afterwards
The characteristic point of side image left side edge matches, according to mating structure by rear center's image and rear left side image registration, and will after
Center image is registrated with rear image right, after rear center's image, rear left-side images and the rear image right after registration are fused into
180 degree image.
The preceding 180 degree image and rear 180 degree image obtained by image processing unit is shown on the display unit, in this reality
It applies in example, image processing unit is connected via display switching switch with display unit, when display switching switching to state one
When, 180 degree image before showing on display unit, when display switches switching to state two, 180 after being shown on display unit
Spend image.
Display switching switch can be established with the car running computer of vehicle to be communicated, and when car running computer provides astern signal, is shown
Show that switching switch automatically switches to state two, so that 180 degree image after showing on the display unit, provides conveniently for reversing.
Those skilled in the art can give up the technical solution of display switching switch, and use two display units, and two
Display unit shows preceding 180 degree image and rear 180 degree image respectively.
Meanwhile preceding 180 degree image and rear 180 degree image can also be stored in RAM card by those skilled in the art, for after
It is continuous to have access to.
Since the voltage of automobile is 12V or 24V, therefore working voltage design of the invention is 11 to 35V to meet
The needs of all vehicles.The present invention, with car engine starting device, is not used by the way of being directly connected to cigar lighter and being powered
Battery plate charging modes are powered, specifically: being preceding camera group, the rear camera group, image procossing by power module
Unit and display unit provide working power, and the power input of power module is connected with the cigar lighter of vehicle.
