Description of the drawings
It to describe the technical solutions in the embodiments of the present invention more clearly, below will be to institute in the prior art and embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the present invention
Example, for those of ordinary skill in the art, without creative efforts, can also obtain according to these attached drawings
Obtain other attached drawings.
The flow diagram of method that Fig. 1 is shown by the control reverse image that the embodiment of the present invention provides；
The schematic diagram of device that Fig. 2 is shown by the control reverse image that the embodiment of the present invention provides.
Specific embodiment
The core of the present invention is to provide a kind of method that reverse image is controlled to show, this method can not influence
While Android onboard navigation systems start the time, the quick display of reverse image is realized.The present invention another core be
There is provided that a kind of that the reverse image device, computer readable storage medium and the automatic navigator that show is controlled to be respectively provided with is above-mentioned beneficial
Effect.
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
It please refers to Fig.1, Fig. 1 is illustrated by the flow of method that the control reverse image that the embodiment of the present invention provides is shown
Figure；With reference to figure 1 it is found that this method may comprise steps of：
S100：Start Android onboard navigation systems；
S200：The Bootloader stages in Android onboard navigation system start-up courses call default processor；
Specifically, ACC is powered on, start Android onboard navigation systems, the Bootloader stages wherein are each to CPU
Core processor is configured, and when CPU integrates two core processors, one of core processor can be set to be
Android onboard navigation systems start processor, are responsible for starting Android onboard navigation systems；Another core processor
The processor that reverse image is shown in order to control is then set, is responsible for detection astern signal and processing, display reverse image.Work as CPU
During integrated multiple cores processor, for example, during four core processors, core0 therein can be set to be that Android is vehicle-mounted and led
Boat system starts processor, the core1 processors that reverse image is shown in order to control, and core2 and core3 are set as IDLE, i.e.,
Idle state.Certainly, correspondence of operation is performed with it for each core processors of CPU, the present invention is not especially limited, can
To make the setting of otherness according to actual conditions.While can realizing startup Android onboard navigation systems, move backward
Signal detection and reverse image processing and display.
Based on above-mentioned setting, further, shown, and then realize the mesh quickly moved backward to realize that 2-3S carries out reverse image
, in the Bootloader stages, default processor is called, that is, is responsible for the processor that control reverse image is shown, to pass through this
Default processor, carries out the operations such as follow-up astern signal detection.
S300：By presetting processor, detect whether to receive astern signal；If receiving astern signal, fallen
Vehicle image processing, and the reverse image after display processing.
Specifically, when detecting astern signal by default processor, i.e., when gear is suspended to reverse gear by car owner, preset place
Reason device can immediately pass through coherent video obtain equipment, such as vehicle-mounted camera, obtain reverse image, and to the reverse image into
Row processing, further by treated, reverse image is shown on screen, so as to provide reference for driver's reversing.
It if, can be after the Bootloader stages on the contrary, do not receive astern signal in the Bootloader stages
The detection of astern signal is carried out again, and when detecting astern signal, show reverse image.It is, of course, also possible to
The detection of astern signal is no longer carried out after the Bootloader stages, until Android onboard navigation system start completions.
In addition, after Android onboard navigation system start completions, above-mentioned pattern, i.e. each core of CPU can be continued according to
Heart processor still sets according to correlation and performs relevant operation.It is, of course, also possible to above-mentioned pattern is exited, it is vehicle-mounted according to Android
The original operating mode of navigation system works, i.e., performs reversing by the APK application programs in Android onboard navigation systems
Signal detection, the operations such as reverse image processing, display.In this regard, the present invention is not construed as limiting, can determine according to actual needs.
In conclusion the method that control reverse image provided by the present invention is shown, is opened in Android onboard navigation systems
In the Bootloader stages of dynamic process, the display of reverse image can be detected and carry out, Android is vehicle-mounted to be led without waiting for
Boat system completes start-up operation, so as in the case where meeting low-power consumption, cold start-up requirement, realize the quick of reverse image
Display.Further, since in Android onboard navigation system start-up courses, default processor is called to carry out astern signal detection
And reverse image processing, display, i.e., different processing operations is carried out by the different processor of CPU respectively, can reached both
Android onboard navigation systems are not influenced and start the time, while ensure the purpose of quick display reverse image again.
On the basis of above-described embodiment：
As a preferred embodiment, this method can also include：
If not receiving astern signal in the Bootloader stages, in Android onboard navigation system start-up courses
The Kernel stages, call default processor；
Processor is preset by this, detects whether to receive astern signal；If receiving astern signal, reversing shadow is carried out
As processing and display.
Although specifically, do not receive astern signal in the Bootloader stages due to being likely to occur, later
The Kernel stages receive the situation of astern signal, so, can when not receiving astern signal in the Bootloader stages,
The Kernel stages detect whether to receive astern signal again；If receiving astern signal in the Kernel stages, equally into
The processing and display of row reverse image.
By the preferred embodiment, can further ensure real in Android onboard navigation system start-up courses
The quick display of existing reverse image.
On the basis of above-described embodiment：
As a preferred embodiment, the method can also include：
After Android onboard navigation system start completions, default processor is discharged, astern signal inspection is carried out by APK
It surveys and reverse image processing is with showing.
Specifically, after Android onboard navigation system start completions, above-mentioned pattern can be exited, discharges default processing
Device, each core processor of CPU can work according to system default pattern.It is and after this, vehicle-mounted by Android
The APK application programs of navigation system carry out the operations such as astern signal detects and reverse image is shown.
By the preferred embodiment, each core processor of CPU can be made full use of, improves Android vehicle mounted guidances
The working efficiency of system.
