Abstract
The open a kind of 270 degree of auxiliary parking systems of the utility model, comprise be arranged on car body left and right, after three cameras, be arranged on the image processing apparatus in operator's compartment and read out instrument; A described left side, latter two camera have overlay region, visual field, and the described right side, latter two camera have overlay region, visual field.The utility model arranges wide-angle camera by left and right at car body, rear three angles and carries out Real-time Collection to left and right vehicle wheel and posterior images, the vision signal collected is carried out input and display device after visual angle effect and synthesis fusion treatment through described DSP image processing apparatus, thus realize the accurate panoramic picture showing around vehicle rear 270 degree on the display apparatus in real time, safety when ensure that automobile parking and accurate reliability, simultaneously, DSP processing module cost is low, and decrease a camera, reduce further cost.
Description
Technical field
The utility model relates to vehicle electric field, especially relates to a kind of 270 degree of accurate panorama auxiliary parking systems.
Background technology
Early stage parking assisting system adopts radar or single camera usually, adopt the mode of audible alarm or display rear view of vehicle camera video image, help vehicle driver to judge blind angle place's vehicle and obstacle distance, but adopt radar type of alarm, the display of distance is not directly perceived; Adopt post-positioned pick-up head mode, then still can there is blind angle and the inaccurate problem of Distance Judgment, so panorama is parked, technology is risen gradually.At present, the auxiliary product of parking of commercially available automobile is generally install single vehicle backing backsight camera at automobile tail, to reach the situation can seeing tailstock portion when moveing backward, single camera only catches the situation in tailstock portion, easily causes potential safety hazard when there are complex situations for vehicle-surroundings when parking.Also the automobile had is auxiliary, and product of parking is installed four cameras at motor vehicle environment and is realized 360 degree of panoramas and park, but this requires performance-oriented image processor and four cameras, makes cost costly.For this reason, need a kind of safety improving automobile parking, and the parking system reduced costs.
Utility model content
The purpose of this utility model is to provide a kind of 270 degree of accurate panorama auxiliary parking systems, solves the problem that existing panorama auxiliary parking system cost is higher.
The utility model solves the technical scheme that its technical matters adopts: a kind of 270 degree of auxiliary parking systems, comprise be arranged on car body left and right, after three cameras, be arranged on the image processing apparatus in operator's compartment and read out instrument; A described left side, latter two camera have overlay region, visual field, and the described right side, latter two camera have overlay region, visual field.
Preferably, the camera on the left of described car body and right side is arranged in automobile rearview mirror, on rear side of described car body, camera is arranged on automotive back door, described camera image mouth is connected with image processing apparatus input end, and described image processing apparatus mouth is connected with read out instrument.
Preferably, described car body left and right, after camera be wide-angle camera.
Further, described image processing apparatus comprises DSP processing module and Logic control module.
The beneficial effects of the utility model: wide-angle camera is set by left and right at car body, rear three angles Real-time Collection is carried out to left and right vehicle wheel and posterior images, the vision signal collected is carried out input and display device after visual angle effect and synthesis fusion treatment through described DSP image processing apparatus, thus realize the accurate panoramic picture showing around vehicle rear 270 degree on the display apparatus in real time, safety when ensure that automobile parking and accurate reliability, simultaneously, DSP processing module cost is low, and decrease a camera, reduce further cost.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present utility model.
Fig. 2 is the utility model circuit theory schematic diagram.
Detailed description of the invention
Embodiment, as shown in Figure 1 and Figure 2, a kind of 270 degree of auxiliary parking systems, comprise be arranged on car body 1 left and right, after three cameras 2, be arranged on the image processing apparatus 3 in operator's compartment and read out instrument 4; A described left side, latter two camera 2 have overlay region, visual field, and the described right side, latter two camera 2 have overlay region, visual field.
The camera 2 on the left of described car body and right side is arranged in automobile rearview mirror 11, on rear side of described car body, camera 2 is arranged on automotive back door, described camera 2 output end of image is connected with image processing apparatus 3 input end, and described image processing apparatus 3 mouth is connected with read out instrument 4.Described car body 1 is left and right, after camera 2 be wide-angle camera.By installing three wide-angle cameras at automobile, wide-angle camera is enable to cover region around automobile rear, and, for a left side, latter two camera 2 is with right, latter two camera 2, they have certain public view field each other, then series of computation is carried out to calibrating template, obtain the parameter representing and splice relation between adjacent wide-angle camera, according to these parameters, through image mosaic and fusion treatment, produce 270 degree of virtual accurate panorama birds-eye view pictures, by the read out instrument 4 of image transmitting to vehicle drive indoor, automobile driver is made to see the accurate panoramic picture of automobile rear 270 degree clearly when moveing backward, thus safety when ensure that automobile parking and accurate reliability.
Described image processing apparatus 3 comprises DSP processing module 31 and Logic control module 32.Described image processing apparatus 3 external connection comprises, control signal wire, power lead, three video input Xian Ji mono-road, road video output cables.Camera 2 gathers left and right, the rear trizonal real-time pictures of automobile, gives image processing apparatus 3 by the video signal collected.Image procossing fills 3 and puts and carry out the conversion of vision to the three road realtime graphics gathered and be seamless splicedly fused into a road vision signal, under the control of Logic control module 32, be transported to read out instrument 4 by by fusion Hou mono-tunnel vision signal, show virtual accurate panoramic picture by read out instrument 4.
After automobile starting, power to image processing apparatus 3 and open image processing apparatus 3, make to be arranged on three wide-angle cameras on automobile, can cover automobile left and right, after region, the shooting around automobile rear is transferred to image processing apparatus 3 and carries out splicing and be fused into a road video image.
When automobile is linked into reverse, trigger image processing equipment 3 astern signal, DSP processing module 31 is merged Hou mono-tunnel transmission of video images on the read out instrument 4 of vehicle drive indoor by the Logic control module 32 in image processing apparatus 3, automobile driver is made to see the accurate panoramic picture of automobile rear 270 degree of scopes clearly when moveing backward, safety when ensure that automobile parking and accurate reliability.
