Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
In order to overcome the above existing defects, the present embodiment provides a vehicle navigation method, which is applied to a navigation terminal device, and the vehicle navigation method includes the following steps: responding to the detection that the navigation terminal equipment enters the designated area, and acquiring spatial layout data of the designated area, wherein the spatial layout data is used for representing two-dimensional or three-dimensional actual spatial layout in the designated area; drawing a navigation map of the designated area by combining the original map data of the designated area and the acquired spatial layout data in the map application; the navigation map is output for vehicle navigation within the designated area.
In this embodiment, the navigation terminal device may be a vehicle-mounted navigation terminal device, a smart phone, a tablet computer, or the like, and the type of the navigation terminal device is not particularly limited, and the navigation terminal device may be selected and adjusted accordingly according to actual conditions.
In this embodiment, the designated area may be a place such as a mobile city area or a parking lot area where fine map data cannot be provided or accurate positioning cannot be provided due to a special reason, but is not limited thereto, and may be a non-special area, and may be selected and adjusted accordingly according to actual situations.
In this embodiment, the designated area may be a polygonal area in a two-dimensional space, or may be a planar area in a certain height range in a three-dimensional space, for example, an underground parking lot, and may be selected and adjusted accordingly according to actual situations.
In the embodiment, in a specific scene such as a mobile city, a parking lot, and the like, a high-definition local map with high fineness can be effectively provided to display more detailed contents such as specific parking spaces and the like for a navigation user, so that the navigation of the user in the specific scene is realized more efficiently.
Specifically, as an embodiment, as shown in fig. 1, the vehicle navigation method provided by the present embodiment mainly includes the following steps:
In this step, the position of the navigation terminal device on the vehicle is acquired in real time by means of GPS (global positioning system) positioning and the like, and in response to detecting that the position of the navigation terminal device is close to or enters a designated area, the identity information of the navigation terminal device is verified by the cloud server, that is, the cloud server can be set to provide a navigation map and high-precision positioning service for the navigation terminal device with the designated identity information, so that the navigation smoothness can be ensured, and the navigation terminal device with an illegal identity can be effectively prevented from accessing the service.
Specifically, the navigation terminal device sends identity information to the cloud server, and the cloud server performs verification according to the received identity information and then feeds back feedback information for representing authentication to the navigation terminal device to indicate that the verification is passed.
In this step, the navigation terminal device obtains the spatial layout data of the designated area from the local data stored in the cloud server or the navigation terminal device in response to receiving the feedback information for representing that the authentication passes from the cloud server.
In this embodiment, the spatial layout data is used to represent a two-dimensional or three-dimensional actual spatial layout in the designated area, and is generally vector picture data, for example, the spatial layout data may be specific stall layout data of a mobile marketplace or specific parking space layout data of a parking lot, and the cloud server may acquire the spatial layout data from a management server in the designated area, or may store the spatial layout data in the navigation terminal device in advance.
And 102, drawing the navigation map of the appointed area by combining the original map data and the spatial layout data.
In this step, a navigation map of the designated area is drawn by combining the original map data and the acquired spatial layout data of the designated area in the map application.
In this embodiment, the navigation map is a high-definition map, the scale size of the navigation map can be enlarged to more than 1m, and the navigation map is matched with the map coordinate height (even 100%), so that the specified area can be enlarged and viewed with high fidelity, and the navigation map can be selected and adjusted correspondingly according to actual requirements.
Specifically, in this step, map data correspondingly converted by the acquired spatial layout data is added to the map data of the specified area in the map application to generate navigation map data of the specified area, and a navigation map of the specified area is drawn based on the generated navigation map data of the specified area.
In this step, after the navigation map is drawn, a POI (point of interest) specified by the user, for example, a specified parking space, may be set in the navigation map according to data on the vehicle or the cloud server, and the POI may be directionally pushed to a map display interface of the user navigation terminal device. As an optional implementation manner, taking a mobile bazaar area as an example, a mobile bazaar means that a certain block is temporarily arranged to be used as a bazaar, and a storefront in the bazaar is a vehicle, so that each parking space can be regarded as a store, each parking space is generally used by being specifically bound with one vehicle, and the cloud server generally stores designated parking space information of the bound vehicle.
In the step, after the navigation map is drawn, the designated parking space information of the navigation vehicle in the mobile urban area is received, the designated parking space corresponding to the designated parking space information is inquired in the fine navigation map, and the navigation map and the designated parking space are output to a display screen of the navigation terminal device so as to carry out vehicle navigation pointing to the designated parking space.
Preferably, in this step, the free parking space information of the mobile city-gathering area may also be obtained, the free parking space corresponding to the free parking space information is inquired out in the navigation map, and the free parking space is displayed in the navigation map so as to recommend the free parking space to the vehicle user.
Because the local navigation map is used differently in the mobile city area and the parking lot, the position where the vehicle can stop every day in the mobile city area is theoretically fixed. When a vehicle enters a mobile city region and receives a navigation map, the cloud server can simultaneously push an appointed parking space address to the navigation terminal equipment of the vehicle and can navigate according to the appointed parking space address, so that not only can a fine navigation map be obtained, but also the recommendation of the appointed parking space position can be received, and the vehicle can conveniently use a local area map to navigate.
If some vehicles in the mobile urban area cannot enter the area for opening a store on a certain day. The information of forbidding parking in the area is cancelled by the cloud server, the parking space is used as an idle parking space, and then the address of the idle parking space is used as second parking space information to be recommended to the vehicle to be navigated. If the position of the second space is better (e.g., closer to the entrance or higher consumer consumption) than the position of the first space (i.e., the originally designated space), the vehicle is preferentially recommended with the better space.
Specifically, referring to fig. 4, when there is no free parking space, the bound (license plate) designated parking space and the navigation map are recommended to the user a to be navigated at the same time. Referring to fig. 5, it is assumed that a vehicle and a cloud server in a position where the vehicle/other license plate 5 is prohibited from parking cancel the rental mobile marketplace. Then, the parking space is recommended to the user a as an idle spare parking space, the user a considers that the position is more suitable for the user, a request for changing the mobile market parking space needs to be sent to the cloud server, the cloud server receives the request, checks whether the position can be changed to the user a (whether the cost needs to be increased, whether the size of the parking space is suitable, and whether the available time range is suitable or not), sends confirmation information, and confirms again by the user a as shown in fig. 6, the parking space is changed to the user a, and meanwhile, the position of the user a is changed to a new parking space which can be selected by a new user in a navigation map, so that the parking space can be rented.
And 103, positioning the vehicle according to the positioning signal transmitting equipment.
In this embodiment, at least one positioning signal transmitting device may be respectively disposed at preset positions in the designated area, and the at least one positioning signal transmitting device may be disposed at preset intervals, for example, 10m intervals, or one positioning signal transmitting device may be respectively disposed in each preset area of the designated area, for example, one positioning signal transmitting device may be disposed in each 10 square meters, and the specific setting position of the positioning signal transmitting device may be set in combination with the configuration of the positioning signal transmitting device.
In this embodiment, the positioning signal transmitting device may be a bluetooth device or a Wi-Fi device, but the type thereof is not particularly limited as long as the corresponding function can be implemented.
In the step, the positioning signal transmitting equipment transmits the positioning signal in real time within the designated range, and the navigation terminal equipment responds to the received radio-frequency signal transmitted by the positioning signal transmitting equipment and positions the navigation terminal equipment according to the position of the positioning signal transmitting equipment, so that the accurate positioning of the vehicle is realized, and centimeter-level positioning can be realized.
And step 104, navigating the vehicle in real time according to the navigation map and the position of the vehicle.
In this step, the navigation terminal device receives designated location information, such as designated parking space information, according to a user instruction or a POI, queries a designated parking space corresponding to the designated parking space information in the navigation map, and navigates the vehicle to the designated parking space in real time according to the designated parking space in the navigation map and the real-time positioning information of the vehicle. In this embodiment, after entering the designated area, the user may also select to switch to the navigation map picture or the original map picture automatically or manually, that is, when the map switching instruction is obtained, the original map and the navigation map are switched according to the received map switching instruction, so that convenient operation and navigation experience are realized, and the user experience is further improved.
According to the vehicle navigation method provided by the embodiment, under specific scenes such as a mobile city, a parking lot and the like, a high-definition local map with high fineness can be effectively provided so as to display more detailed contents such as specific parking spaces for a navigation user, an idle parking space can be recommended to the user, the positioning efficiency and precision are improved, the user is helped to realize more efficient navigation and vehicle searching under the specific scenes, and the user experience degree is improved.
