The left region on display in panorama sketch is clicked at family, and the vehicle-mounted panoramic image system enters left view state；If user clicks
Right region on display in panorama sketch, the vehicle-mounted panoramic image system enter right view state；If user presses institute again
When stating the return soft-key button on the hard key or display of vehicle-mounted panoramic image system, the vehicle-mounted panoramic image system is returned
Standby mode.If speed is less than Vkm/h, and vehicle exits R gear, and the vehicle-mounted panoramic image system can also enter forward sight shape
State.If speed is greater than Vkm/h, the vehicle gear is non-R gear, and the vehicle-mounted panoramic image system can also return to standby shape
State.
Under 2D mode, the picture under the forward sight state on display is forward sight and 2D panorama sketch, under the left view state
Picture on display is left view and 2D panorama sketch, and the picture under the backsight state on display is backsight and 2D panorama sketch,
The right picture depending on display under state is right view and 2D panorama sketch.
Wherein, standby mode refers to that remaining module in this system in addition to display module 500 is in working condition, but aobvious
Show that module 500 does not show that image involved in the present invention, Vkm/h can be set to 30km/h.
A kind of 3D operating mode of vehicle-mounted panoramic image system is provided in a feasible embodiment of the invention, specifically
Ground, as shown in Figure 10, the 3D operating mode of the vehicle-mounted panoramic image system are as follows：
When the vehicle-mounted panoramic image system is in the standby state, speed is less than Vkm/h, and the vehicle gear is non-R
When gear, and linked switch opening is turned to, if vehicle turns to the left, the vehicle-mounted panoramic image system enters left turn state；Such as
Fruit vehicle turns to the right, and the vehicle-mounted panoramic image system enters right turn state.
When the vehicle-mounted panoramic image system is under 2D mode, speed is less than Vkm/h, and the vehicle gear is non-R gear
When, if user, which clicks " 2D/3D ", switches soft-key button, the vehicle-mounted panoramic image system enters the backsight state of 3D mode；
If vehicle turns to the left, and turns to linked switch opening, the vehicle-mounted panoramic image system enters left turn state；If vehicle
It turns to the right, and turns to linked switch opening, the vehicle-mounted panoramic image system enters right turn state.
When the vehicle-mounted panoramic image system is under backsight state, speed is less than Vkm/h, and the vehicle gear is non-R
When gear, if vehicle turns to the left, and turns to linked switch opening, the vehicle-mounted panoramic image system enters left turn state；
If vehicle turns to the right, and turns to linked switch opening, the vehicle-mounted panoramic image system enters right turn state；If with
The hard key or the soft-key button on display that family again taps on the vehicle-mounted panoramic image system, the vehicle-mounted panoramic image system
Return to standby mode；If user again taps on " 2D/3D " switching soft-key button, the vehicle-mounted panoramic image system returns to 2D mode
Forward sight state.When speed is greater than Vkm/h, the vehicle-mounted panoramic image system can also return to standby mode.
When the vehicle-mounted panoramic image system is under left turn state, if speed is less than Vkm/h, the vehicle gear is
When non-R is kept off, and vehicle exits left steering, and the vehicle-mounted panoramic image system enters the backsight state of 3D mode；If speed
Greater than Vkm/h, the vehicle-mounted panoramic image system returns to standby mode.
When the vehicle-mounted panoramic image system is under right turn state, if speed is less than Vkm/h, the vehicle gear is
When non-R is kept off, and vehicle exits right turn, and the vehicle-mounted panoramic image system enters the backsight state of 3D mode；If speed
Greater than Vkm/h, the vehicle-mounted panoramic image system returns to standby mode.
Under 3D mode, the picture under the backsight state on display is front view and 3D rearview, the left turn state
Picture on lower display is front view and left steering 3D view, the picture under the right turn state on display be front view and
Right turn 3D view.
3D operating mode provided in this embodiment mainly solves the problems, such as vehicle there are pillar A blind, enables driver
The clear image for seeing vehicle periphery in time, prevents contingency.
Wherein, standby mode refers to that remaining module in this system in addition to display module 500 is in working condition, but aobvious
Show that module 500 does not show that image involved in the present invention, Vkm/h can be set to 30km/h.
A kind of implementation method of vehicle-mounted panoramic image system is provided in a feasible embodiment of the invention, specifically,
As shown in figure 11, the method includes：
