Method for indicating parking position and vehicle-mounted device

1. A parking position reminding method comprising:

obtaining panoramic images of a vehicle during driving through a panoramic lens;

identifying a driving path of the vehicle according to the panoramic images;

determining whether the vehicle is at a parking position;

sending parking position information to a mobile terminal when the vehicle is at the parking position;

comparing the panoramic images with an image of a preset area;

determining that the vehicle locates at the parking position when the panoramic image is consistent with the image of the preset area; and

transmitting a route to the mobile terminal at a preset frequency and updating the route stored in the mobile terminal when the mobile terminal is physically approaching the vehicle,

wherein the preset area comprises specific elements indicating that a current area is a parking area, when the panoramic image is determined to include the specific elements, the panoramic image is determined to be consistent with the image of the preset area;

wherein the step of identifying the driving path of the vehicle according to the panoramic images comprises:

comparing the panoramic images with a road image in a preset high-precision map;

selecting multiple reference points in a preset high-definition map based on the panoramic image, wherein the multiple reference points at least comprise a road and a surrounding environment; and

determining the driving path which comprises a road displayed in the road image when a coincidence rate of the reference points appearing in the panoramic image reaches or exceeds a preset value.

2. The parking position reminding method of claim 1 , further comprising:

obtaining a driving direction of the vehicle to determine a number of turns of the vehicle;

determining a floor where the vehicle locates according to the number of turns of the vehicle or the panoramic images;

wherein the parking position information comprises the floor.

3. The parking position reminding method of claim 2 , wherein the driving direction of the vehicle is obtained through a gyroscope or calculated by the panoramic images.

4. The parking position reminding method of claim 1 , wherein the preset area is a parking area, and the mobile terminal connects the vehicle through a wireless connection.

5. The parking position reminding method of claim 1 , wherein the parking position information comprises parking space information or the driving path of the vehicle.

6. The parking position reminding method of claim 5 , wherein the parking space information comprises a parking space code.

7. The parking position reminding method of claim 1 , wherein the parking position information is sent to the mobile terminal via Bluetooth when the vehicle is located at the parking position.

8. A vehicle-mounted device comprising:

a storage device;

at least one processor configured to:

obtain panoramic images of a vehicle during driving through a panoramic lens;

identify a driving path of the vehicle according to the panoramic images;

determine whether the vehicle is at a parking position;

send parking position information to a mobile terminal when the vehicle is at the parking position;

compare the panoramic images with an image of a preset area;

determine that the vehicle locates at the parking position when the panoramic image is consistent with the image of the preset area; and

transmit a route to the mobile terminal at a preset frequency and update the the route stored in the mobile terminal when the mobile terminal is physically approaching the vehicle,

wherein the preset area comprises specific elements indicating that a current area is a parking area, when the panoramic image is determined to include the specific elements, the panoramic image is determined to be consistent with the image of the preset area;

wherein the at least one processor configured to identify the driving path of the vehicle according to the panoramic images comprises:

comparing the panoramic images with a road image in a preset high-precision map;

selecting multiple reference points in a preset high-definition map based on the panoramic image, wherein the multiple reference points at least comprise a road and a surrounding environment; and

determining the driving path which comprises a road displayed in the road image when a coincidence rate of the reference points appearing in the panoramic image reaches or exceeds a preset value.

9. The vehicle-mounted device of claim 8 , the at least one processor is further configured to:

obtain a driving direction of the vehicle to determine a number of turns of the vehicle;

determine a floor where the vehicle locates according to the number of turns of the vehicle or the panoramic images;

wherein the parking position information comprises the floor.

10. The vehicle-mounted device of claim 9 , wherein the driving direction of the vehicle is obtained through a gyroscope or calculated by the panoramic images.

11. The vehicle-mounted device of claim 8 , wherein the preset area is a parking area, and the mobile terminal connects the vehicle through a wireless connection.

12. The vehicle-mounted device of claim 8 , wherein the parking position information comprises parking space information or the driving path of the vehicle.

13. The vehicle-mounted device of claim 12 , wherein the parking space information comprises a parking space code.

14. The vehicle-mounted device of claim 8 , wherein:

the parking position information is sent to the mobile terminal via Bluetooth when the vehicle is located at the parking position.
