NAVIGATION METHOD BASED ON WAYSIDE REFERENCE OBJECT MATCHING
The invention provides a navigation method and in particular a navigation method based on wayside reference object matching. In order to realize navigation in places that are not covered with GPS or BeiDou navigation signals, the navigation method based on wayside reference object matching comprises the steps of: acquiring navigation information based on at least one wayside reference object in a first trip (S 210 ); searching in a second trip for a base point matched with any of the at least one wayside reference object (S 220 ); and using the navigation information to navigate when the base point matched with any of the at least one wayside reference object is found (S 230 ). In the application scenario of a parking lot, the navigation method can realize the navigation for a vehicle searching person in a parking lot without GPS or BeiDou navigation coverage, thereby improving the vehicle searching person's efficiency in finding the vehicle.
1 . A navigation method based on wayside reference object matching, the method comprising the steps of:
acquiring navigation information based on at least one wayside reference object in a first trip;
searching in a second trip for a base point matched with any of the at least one wayside reference object; and
using the navigation information to navigate when the base point matched with any of the at least one wayside reference object is found.
2 . The navigation method based on wayside reference object matching according to claim 1 , wherein the at least one wayside reference object comprises a plurality of wayside reference objects, and the navigation information comprises a position of each of the plurality of wayside reference objects and a first navigation path between the plurality of wayside reference objects.
3 . The navigation method based on wayside reference object matching according to claim 2 , wherein the first navigation path comprises a first adjacency navigation path between the adjacent wayside reference objects and a first non-adjacency navigation path between the nonadjacent wayside reference objects.
4 . The navigation method based on wayside reference object matching according to claim 3 , wherein the navigation information also comprises a second navigation path from each of the plurality of wayside reference objects to a destination.
5 . The navigation method based on wayside reference object matching according to claim 4 , wherein the step of searching in a second trip for a base point matched with any of the at least one wayside reference object further comprises: searching in the second trip for the same wayside reference object as any of the wayside reference objects.
6 . The navigation method based on wayside reference object matching according to claim 5 , wherein the step of using the navigation information to navigate further comprises: using the first adjacency navigation path to navigate.
7 . The navigation method based on wayside reference object matching according to claim 6 , wherein the step of using the navigation information to navigate also comprises: using the second navigation path and/or the first non-adjacency navigation path to navigate, if the wayside reference object matched with a certain wayside reference object in the first trip cannot be found in the second trip during navigation with the first adjacency navigation path.
8 . The navigation method based on wayside reference object matching according to claim 1 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
9 . The navigation method based on wayside reference object matching according to claim 8 , wherein the first trip is the trip of the vehicle to the destination, and the second trip is the trip of a subject required to reach the destination.
10 . The navigation method based on wayside reference object matching according to claim 9 , wherein the step of acquiring navigation information based on at least one wayside reference object in a first trip comprises:
during the trip of the vehicle to the destination, photographing the license plates of the roadside vehicles for the first time at a predetermined frequency; and/or
determining a navigation path between the roadside vehicles; and/or
determining a navigation path from the roadside vehicle to the destination.
11 . The navigation method based on wayside reference object matching according to claim 10 , wherein the step of searching in a second trip for a base point matched with any of the at least one wayside reference object comprises:
in the process of the subject required to reach the destination heading to the destination, photographing the license plates of the roadside vehicles for the second time; and
searching the license plates obtained during the photographing for the second time for the same license plates as the license plates obtained during the photographing for the first time.
12 . The navigation method based on wayside reference object matching according to claim 11 , wherein the vehicle is an electric vehicle, and the subject is a service person who delivers a valet charging service.
13 . The navigation method based on wayside reference object matching according to claim 2 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
14 . The navigation method based on wayside reference object matching according to claim 3 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
15 . The navigation method based on wayside reference object matching according to claim 4 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
16 . The navigation method based on wayside reference object matching according to claim 5 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
17 . The navigation method based on wayside reference object matching according to claim 6 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
18 . The navigation method based on wayside reference object matching according to claim 7 , wherein the navigation method is a navigation method for a vehicle, and the wayside reference objects are license plates of roadside vehicles during a trip of the vehicle to the destination.
