Description
Technical field
The present invention relates to onboard system technical fields, and in particular to the quick display based on multicore park image method and
Device.
Background technique
The reverse image system of automobile is a kind of parking assisting system, after using wide-angle camera apparatus to be mounted on automobile
The information of automobile rear road can be clearly displayed by portion by interior display screen, after intuitive prompt driver's vehicle
Ambient conditions provides convenience to park, moving backward.And with development in science and technology, it is in recent years even more to have developed panorama to park image system
System is a set of by the 360 degree of panoramas fusions of car-mounted display screen viewing automobile surrounding, and ultra-wide visual angle, seamless spliced is in due course
Image information understands vehicle-surroundings sight blind area, helps that driver is more intuitive, safer ground parked vehicle parks
Auxiliary system.
In embedded systems, there are three types of general reverse image schemes, one is after kernel start completion by apply journey
Sequence calls kernel-driven to realize, realizes very simple, using flexible, but since the starting time is longer, back-up video needs longer
Time could show on a display screen, bring great inconvenience to the use of user.Second is in bootloader
It realizes, the speed that back-up video is shown is exceedingly fast, but can not continue to start kernel simultaneously when the disadvantage is that showing back-up video.User exists
If it is desired to needing to wait the longer starting time using the function that system provides, user experience is poor after reversing.The third
It is to be realized in kernel starting by driver, compared to both above, both belong in taking, both meet starting speed and compare
Comparatively fast, it and meets during reverse image display, it, can be fast when astern signal terminates using synchronous averaging
Speed is switched to user interface, and user experience is relatively good,
And current parking assisting system, it is aobvious using monokaryon framework, Image Acquisition and display and graphical interfaces mostly
Show there is Linux management, in kernel starting, the logic of reverse image is realized by driver, current scheme is in multicore frame
It is not very efficiently, not play the advantage of respective processor in structure.
