Abstract
A method for indicating to a user the exact location of a parked vehicle includes obtaining a plurality of panoramic images of a vehicle when being driven using a panoramic lens. A direction of driving of the vehicle is identified based on the panoramic images and a determination as to location is made when the vehicle arrives at a parking location. When the vehicle is parked, parking position information is sent to a mobile terminal held by the driver or other user. A vehicle-mounted device for implementing the method is also disclosed.
Claims14
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.

- 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.
