All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a vehicle information display method and device, electronic equipment and a storage medium. Specifically, the embodiment of the present application provides a vehicle information display device suitable for an electronic device, which may be a terminal or a server.

It is understood that the vehicle information display method of the present embodiment may be executed on the terminal, may be executed on the server, or may be executed by both the terminal and the server.

A terminal 10 operable to: displaying a map page, wherein the map page comprises a map corresponding to the current position, and the map comprises at least one geographic area and vehicle icons of vehicles around the current position; when the real-time geographic position of the vehicle is acquired, the vehicle icon in the map page is controlled to be displayed in a smooth moving mode from a starting geographic position to a target geographic position, wherein the target geographic position is a random position in a target geographic area, and the starting geographic position is determined based on the real-time geographic position of the vehicle.

The above-described process of acquiring the target route data by the server 11 may be executed by the terminal 10.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The first embodiment,

The embodiment of the present application will be described in terms of a vehicle information display device, which may be specifically integrated in an electronic device, where the electronic device may be a server or a terminal.

The vehicle information display device of the embodiment of the application can be applied to scenes displayed by various surrounding vehicles to display vehicle information, for example, the vehicle information display device can be applied to scenes of taxi taking in network taxi appointment business, after an application program of taxi taking is started, a map page is displayed, the map page comprises vehicle icons, and the vehicle icons are controlled to move smoothly from the initial geographic position to the target geographic position along a target route on the map for displaying.

As shown in fig. 1b, the specific flow of the vehicle information display method is as follows:

101. and displaying a map page, wherein the map page comprises a map corresponding to the current position, and the map comprises at least one geographic area and vehicle icons of vehicles around the current position.

The current position can be the current position of the terminal, and the vehicle icon is a vehicle identifier corresponding to the actual vehicle in the map page. The vehicle around the current position may be a vehicle within a preset area range centered on the current position, and the preset area range may be set according to an actual situation, which is not limited in this embodiment. For example, the setting may be performed according to the density of the surrounding vehicles, and if the density of the surrounding vehicles is high, the preset area range may be set to be small; if the density of the surrounding vehicles is small, the preset area range may be set to be large.

The geographic area can be obtained by dividing the map in various ways, and can be particularly divided according to actual requirements, which is not limited in this embodiment; such as geographic zones, may be partitioned into latitude and longitude of the earth. In addition, the divided geographical area can be coded.

For example, the geographical zone may be encoded by a geographical hash (geoHash) algorithm to encode the first place for a specific description, assuming that the latitude of the first place is 39.928167 and the longitude is 116.389550, see fig. 1 c. Firstly, carrying out approximate coding on latitude 39.928167 by a geoHash algorithm, wherein the latitude interval of the earth is [ -90,90], firstly carrying out binary division on the interval [ -90,90] into [ -90,0), [0,90], namely left and right intervals, and determining that 39.928167 belongs to the right interval [0,90], and marking as 1; then, dividing the interval [0,90] into [0,45 ], [45,90], determining 39.928167 as belonging to the left interval [0,45 ], and marking as 0; recursion the above procedure 39.928167 always belongs to a certain interval a, b. As each iteration interval [ a, b ] is always shrinking and is approaching 39.928167; if a given latitude x (39.928167) belongs to the left bin, then 0 is recorded, and if it belongs to the right bin, then 1 is recorded, thus producing a sequence 1011100 as the algorithm proceeds, the length of the sequence being related to the number of divisions of the given bin. Similarly, the Earth longitude interval is [ -180,180], and longitude 116.389550 may be encoded. By the above calculation, the latitude-generated code is 1011100011, and the longitude-generated code is 1101001011. Longitude can be placed at even positions, latitude can be placed at odd positions, and the two strings of codes are combined to generate a new string: 11100111010010001111. the binary coded decimal value is 7325935, which is the hash index value (hashIndex) of the geographic tile; finally, base32 (base32) coding is carried out by using 32 letters of 0-9 and b-z (a, i, l and o are removed), 11100111010010001111 is firstly converted into decimal corresponding to 28, 29, 4 and 15 respectively, and the decimal corresponding code is wx4g which is the geographic hash (geoHash) value of the geographic area where the longitude and latitude are located. Similarly, the decoding algorithm for converting the codes into the latitudes and longitudes is opposite to that, and details are not described again.

The digital coding correspondence of the base32 coding algorithm is shown in fig. 1 d. Each letter or number in the geoHash is composed of 5bits (2^5 ^ 32), the 5bits can have different combinations (0-31) in 32, and 32 areas can be identified by 00000-11111. The sequence of 0 and 1 strings in the geoHash algorithm is formed by alternately arranging numbers in a

longitude

0 and 1 sequence and a

latitude

0 and 1 sequence, the sequence corresponding to even bits is a longitude sequence, the sequence corresponding to odd bits is a latitude sequence, when a map is divided for the first time, the first 5bits (11100) in the 0 and 1 sequences in the geoHash algorithm exist, 3bits in the 5bits represent longitude, and 2bits represent latitude, so that the longitude is divided into 8 sections (2^3 ^ 8) and the latitude is divided into 4 sections (2^ 4) in the first time of dividing, and 32 areas are formed. Similarly, the 32 regions obtained by the first division can be divided again in the manner adopted by the first division, and so on.

The geoHash algorithm is essentially a mode of spatial indexing, the basic principle of the geoHash algorithm is that the earth is understood as a two-dimensional plane, the plane is decomposed into smaller sub-blocks in a recursive mode, each sub-block has the same code in a certain latitude and longitude range, and the mode can meet the requirement of carrying out latitude and longitude retrieval on small-scale data. Specifically, the geoHash can convert the latitude and longitude of two dimensions into character strings, as shown in fig. 1e, the geoHash character strings of 9 beijing regions are shown, which are WX4ER, WX4G2, WX4G3, and the like, respectively, and each character string represents a certain rectangular region. That is, all points (longitude and latitude coordinates) in the rectangular area share the same geoHash character string, so that privacy can be protected, only approximate area positions are represented instead of specific points, and caching is easier. The geoIndex value is a decimal code of a block with a certain latitude and longitude calculated by the geoHash algorithm, for example, the geoIndex of the block with 39.928167 and 116.389550 in the above example is 7325935. The geoHash value is calculated by the geoHash algorithm for a block with a certain latitude and longitude, for example, the geoHash value in the above example is 39.928167, and the geoHash value in the block with the longitude 116.389550 is wx4 g.

Note that different coding lengths indicate different range sections. The longer the geoHash string, the smaller the range of representation and the more precise the position. We can therefore determine the approximate distance between two points by comparing the number of bits of the geoHash match. Referring to fig. 1f, the accuracy is around 610 meters when the base32 code length for the geoHash value is 6, and around 19 meters when the code length is 8.

102. When the real-time geographic position of the vehicle is acquired, the vehicle icon in the map page is controlled to be displayed in a smooth moving mode from a starting geographic position to a target geographic position, wherein the target geographic position is a random position in a target geographic area, and the starting geographic position is determined based on the real-time geographic position of the vehicle.

The geographic area may be obtained by dividing the map in various ways, and may be specifically divided according to actual requirements, which is not limited in this embodiment.

Optionally, in some embodiments, the target geographic zone may include a geographic zone in which the current location is located or a geographic zone in which the real-time geographic location of the vehicle is located.

The target geographic zone may be a geographic zone where the current position is located, or a geographic zone where the real-time geographic position of the vehicle is located. For example, a portion of the vehicle icons may be moved smoothly from the starting geographic location to the target geographic location with a random position within the geographic zone in which the current location is located as the target geographic location; and the other part of the vehicle icons are smoothly moved from the starting geographic position to the target geographic position by taking the random position in the geographic area where the real-time geographic position of the vehicle is located as the target geographic position, so that the vehicle icons on the map page do not all run towards the current position, and the display effect is more natural and real.

For example, in an embodiment, the target geographic area may be a geographic area where the real-time geographic location of the vehicle is located, and if the geographic area is obtained by dividing the map based on the geoHash algorithm in step 101, and the length of the geoHash value of the geographic area is 6, that is, the precision of the geoHash value is about 610 meters, the target geographic location is a random location in the target geographic area of 610m × 610 m.

Optionally, the geographic area may be determined according to the partition of the map, and the area range indicated by the geographic area is different based on different partition modes. Specifically, the target geographic zone may refer to a certain area where the current position is located, or may be a certain area where the real-time geographic position of the vehicle is located. In one embodiment, the target geographical area may be a certain area centered on the current location (x, y) of the terminal, where x is longitude and y is latitude. For example, the target geographic zone may be a 400m x 400m grid centered on the current position (x, y) of the terminal, and the target geographic location is a random position in the 400m x 400m grid centered on the current position (x, y) of the terminal.

It will be understood that the above examples should not be construed as limiting the present embodiments.

When the real-time geographic position of the vehicle is acquired every time, the position of the current vehicle icon in the map page is acquired, if the position is consistent with the acquired real-time geographic position of the vehicle, the acquired real-time geographic position of the vehicle can be used as the starting geographic position of the route planning, the starting geographic position is used as the starting point, the target geographic position is used as the end point, the target route of the vehicle icon is acquired, and the vehicle icon is controlled to move smoothly from the starting geographic position to the target geographic position along the target route in the map page; if the position of the current vehicle icon is inconsistent with the collected real-time geographic position of the vehicle, the position of the current vehicle icon is used as an initial geographic position of the route planning, the initial geographic position is used as a starting point, the target geographic position is used as a terminal point, a target route of the vehicle icon is obtained, the target route passes through or approaches the collected real-time geographic position of the vehicle, the motion track of the vehicle icon is adjusted based on the real-time geographic position of the vehicle, the vehicle icon is prevented from deviating too much from the actual motion track of the vehicle, and the vehicle icon is controlled to move smoothly from the initial geographic position to the target geographic position in a map page to be displayed based on the target route.

Optionally, in some embodiments, the step of controlling the vehicle icon to smoothly move and show from the starting geographic position to the target geographic position in the map page may include:

generating a target route for the vehicle icon based on the starting geographic location and the target geographic location of the vehicle icon;

controlling the vehicle icon in the map page to smoothly move and show from a starting geographic position to a target geographic position along the target route.

The route planning service program can be called by starting a plurality of threads, a target route from the starting geographic position to the target geographic position of the vehicle icon is calculated, and the vehicle icon is controlled to smoothly move and display from the starting geographic position to the target geographic position along the target route based on the calculated target route. Optionally, a trolley smooth movement toolkit may be invoked to ensure that the vehicle icons move smoothly on the roads of the map page; specifically, a route planning service program is called to obtain data of a target route from an initial geographic position to a target geographic position of a vehicle icon, the data is written into a trolley smooth moving tool package, the data can contain longitude and latitude point string coordinates, mileage, distance consumed time and other information of the target route, the trolley smooth moving tool package comprises a map tool module, and the vehicle icon can be enabled to move smoothly on a road of a map page along the longitude and latitude point string coordinates of the target route through the map tool module based on the longitude and latitude point string coordinates, the mileage and the distance consumed time. The moving effect can be seen in fig. 1g, 1h and 1i, where fig. 1g, 1h and 1i are moving display diagrams of vehicle icons continuously spaced by several seconds.

Optionally, in some embodiments, the step "generating the target route of the vehicle icon based on the starting geographic location and the target geographic location of the vehicle icon" may include:

generating a plurality of candidate routes for the vehicle icon based on the starting geographic location and the target geographic location of the vehicle icon;

and selecting a target route of the vehicle icon from the candidate routes based on the time consumption of the routes corresponding to the candidate routes.

Wherein the journey elapsed time is the time elapsed for the vehicle icon to travel along the candidate route from the starting geographic location to the target geographic location.

Optionally, in some embodiments, a route planning service may be invoked to calculate a candidate route, a total mileage, and a total route time taken by the vehicle icon from the starting geographic location to the target geographic location; and selecting the candidate route with the shortest route time consumption as the target route based on the total route time consumption.

And the position updating period is an updating period of the real-time geographic position, and the route of the vehicle icon on the map page is re-planned based on the updated real-time geographic position. The location update period may be set according to actual conditions, but in order to prevent the vehicle icon from deviating too much from the actual motion trajectory of the vehicle, the location update period is generally set to be relatively small.

and when the real-time geographic position of the vehicle is acquired, controlling the vehicle icon in the map page to smoothly move and display from the starting geographic position to the target geographic position.

Before the step of "obtaining the target block code of the target geographic block", the method may further include:

coding each geographical block to obtain a block code set, wherein the block code set comprises block codes corresponding to each geographical block;

the obtaining of the target block code of the target geographic block includes:

extracting a target block code for the target geographic block from the set of block codes.

Optionally, the geoHash algorithm may be used to encode each geographic area, and the specific encoding process may be described in step 101. For example, the block code set may specifically pre-code the geographic block and store the pre-coded geographic block in the database, for example, the block code set may store the pre-coded geographic block in a shared account of the block chain, and when the target block code needs to be acquired, the target block code of the target geographic block is extracted from the shared account of the block chain based on the information of the target geographic block and provided to the vehicle information display device.

For another example, the target block code may be obtained by real-time calculation. It is understood that the process of real-time computation may be performed on the server or the terminal. The target block code of the target geographic block may be obtained by coding based on the latitude and longitude information of the target geographic block, and the specific coding process may be described in step 101.

Optionally, in some embodiments, the step of "collecting the real-time geographic location of the vehicle based on the identification information" may include:

The mapping relationship set may be a relationship table of identification information of the vehicle, a real-time geographic location of the vehicle, and a block code corresponding to the real-time geographic location. And searching the real-time geographic position of the corresponding vehicle from the relation table based on the identification information of the vehicle.

The set of mapping relationships may also be an ordered set (zset) of a Remote Dictionary Server (Remote Dictionary Server). Redis is a high-performance key-value (key-value) database, a memory storage system. It is generally called a data structure server, and supports more types of stored values (values), which may be of types such as String (String), Hash (Hash), list (list), set (sets), and ordered set (zset, sorted sets). The zset of Redis is a set of string type elements and no duplicate members are allowed, each element being associated with a double precision (double) type score (score). Redis is precisely the ordering of members in a collection from small to large by scores.

In this embodiment, the Redis may store identification information of the vehicle, a real-time geographic location of the vehicle, and a block code corresponding to the real-time geographic location. In Redis, a keyword (key) is identification information of a vehicle, specifically, an identification number (id) of a driver or a license plate number, and the like, and stored data is the latest real-time geographic position of the vehicle; the score (score) may be a geographic index value (geoIndex) for each geographic zone, and the stored data is identification information of the vehicle. The real-time geographic position of the vehicle can be acquired from Redis by taking the identification information of the vehicle as a key.

The mapping relationship set may be continuously updated, and the specific process may include:

In some embodiments, the vehicle uploads a current real-time geographic location every preset time in the driving process, where the preset time may be set according to an actual situation, and this embodiment is not limited to this, for example, the preset time may be set to 1s, and the vehicle uploads a real-time geographic location every 1 s.

Optionally, the latest uploaded real-time geographic position of the vehicle may be stored in the mapping relationship set, and the real-time geographic position in the mapping relationship set is updated, and in addition, the block code corresponding to the geographic block where the latest uploaded real-time geographic position is located may also be obtained, and the block code corresponding to the real-time geographic position in the mapping relationship set is updated. Referring to fig. 1j, the vehicle may upload a current real-time geographic location to the background at a frequency of 1 time per second, the background calculates a geographic index value of the real-time geographic location, and stores identification information of the vehicle in an ordered set (zset) of a remote dictionary server (Redis), wherein the ordered set may be divided into a plurality of subsets, each subset represents each geographic zone, i.e., corresponds to one grid, if a six-bit geographic hash value is used, the length and width of the geographic zone corresponding to each grid may be about 610 meters in particular, a score (score) may be set as a geographic index value of each geographic zone (grid), and the stored data is the identification information of the vehicle, i.e., stores the identification information of the vehicle in the corresponding grid, which is the geographic index value of the current real-time geographic location of the vehicle, which may be embodied in some embodiments as moving the storage location of the identification information of the vehicle from another grid to the latest real-time geographic location Storing the grids of the corresponding geographic zone; meanwhile, the real-time geographic position of the vehicle needs to be updated to the latest real-time geographic position, and the latest real-time geographic position of the vehicle is stored in Redis. Optionally, in some embodiments, the step of "determining identification information of a vehicle to be displayed according to the target block code" may include:

taking the current position as a circle center, and determining the radius of the range of the vehicle to be displayed;

determining a block code corresponding to a geographical block where the vehicle needs to be displayed based on the range radius and the target block code, wherein the block code corresponding to the geographical block where the vehicle needs to be displayed is an object block code;

and determining the identification information of the vehicle to be displayed based on the object block codes and the mapping relation set.

The mapping relationship set may be a relationship table of identification information of the vehicle, a real-time geographic position of the vehicle, and a block code corresponding to the real-time geographic position, or may be an ordered set (zset) of a remote dictionary server (Redis). Identification information of the vehicle to be displayed can be acquired from the relation table or Redis based on the object block codes.

The step of determining the block code corresponding to the geographic block where the vehicle needs to be displayed based on the range radius and the target block code may specifically include:

determining a geographic zone in which a vehicle needs to be displayed based on the range radius, the target zone code, and the size of the geographic zone;

and taking the block code corresponding to the geographical block needing to display the vehicle as the object block code.

The radius of the range in which the vehicle needs to be displayed may be set by the user, or may be preset by the vehicle information display device, which is not limited in this embodiment. Determining the position range of the vehicle to be displayed based on the range radius of the vehicle to be displayed and the target block code; and determining the geographical area needing to display the vehicle according to the size of each geographical area and the position range needing to display the vehicle.

For example, the geographic hash algorithm geoHash may be used to encode geographic zones, obtain geographic index values of the geographic zones where vehicles need to be displayed by using the radius of the range where vehicles need to be displayed, and efficiently query identification information of vehicles in the geographic zones. As shown in fig. 1k, each grid in the graph represents a geographic area, that is, a coverage range of a geoHash is represented, numbers in the grids represent a geoIndex value geoIndex of the geographic area, if the geoIndex corresponding to the target geographic area is 154, the radius of the range of the vehicle needs to be displayed to be 1km, if a 6-bit geoHash is used during storage, the precision of the length and the width of the geographic area is about 610m, and therefore, the geoIndex value of a grid 2 circles around the grid with the geoIndex of 154 needs to be obtained, and the geoIndex of the grid 2 circles around the grid can be calculated by using a geoHash library (libgehash) (which can be implemented by c + +) of the invention of drick Smith (Derek Smith). The grids of the geoIndex 154 and the grids of 2 circles around the grid of the geoIndex 154 are geographical areas where the vehicles need to be displayed, and the block codes corresponding to the geographical areas where the vehicles need to be displayed are used as target block codes.

The step of determining the identification information of the vehicle to be displayed based on the object block code and the mapping relationship set may specifically include:

acquiring a maximum coding value and a minimum coding value in the object block coding;

determining a candidate vehicle from the set of mapping relationships based on the maximum encoded value and the minimum encoded value;

determining the block code corresponding to the real-time geographic position of the candidate vehicle as the candidate vehicle of the object block code, and determining the candidate vehicle as the vehicle needing to be displayed;

identification information of the vehicle to be displayed is acquired.

The step of "determining candidate vehicles from the mapping relationship set based on the maximum code value and the minimum code value" may specifically include:

and determining the vehicles with the block codes of the geographic block where the vehicles are located in the mapping relation set between the minimum code value and the maximum code value as candidate vehicles.

As shown in fig. 1k, if the grid with geoIndex 154 and the grid 2 circles around the grid with geoIndex 154 are the geographical areas where the vehicles need to be displayed, the maximum code value is 182 and the minimum code value is 134 in the geographical index values of the grid 2 circles around the grid with geoIndex 154. And the vehicles with the geographic index values of 134-182 are candidate vehicles, the candidate vehicles with the block codes corresponding to the real-time geographic positions of the candidate vehicles not belonging to the object block codes are filtered, and the block codes corresponding to the real-time geographic positions of the candidate vehicles belong to the candidate vehicles of the object block codes, so that the candidate vehicles are determined to be the vehicles needing to be displayed. For example, if the set of mapping relationships is zset of redis, because redis is obtained by sorting members in the set from small to large according to scores, the range of the score to be queried is 134 to 182 according to the range search, and a geographic area outside 2 circles of grids around the grid with the geoIndex of 154 is selected, so after data is queried by using redis, it is necessary to determine whether the score of the queried data is in the geographic area where the current position of the user is located, that is, the grid with the geoIndex of 154 and the grid with 2 circles around the grid with the geoIndex of 154, and if not, the block code of the grid corresponding to the score of the data does not belong to the object block code, the grid is an invalid grid, that is, the data is invalid data and needs to be filtered out.

Optionally, in some embodiments, the step of "determining identification information of a vehicle to be displayed according to the target block code" may include:

determining candidate vehicles according to the target block codes;

acquiring vehicle state information of the candidate vehicle;

determining the candidate vehicle with the vehicle state information meeting the preset condition as a vehicle needing to be displayed;

identification information of the vehicle to be displayed is determined.

Wherein the candidate vehicle may be a vehicle around the current position of the passenger; the vehicle state information may specifically be the current state of the vehicle, such as in a bill of hearing or in a service, etc. The preset condition may be set according to the needs of the customer, for example, the customer only wants to see information of an empty vehicle, and the preset condition may be that the vehicle state is empty, that is, in the order, the candidate vehicle is filtered again according to the vehicle state information to obtain the vehicle required by the customer.

Optionally, in some embodiments, the vehicle type of the vehicle, such as a luxury vehicle, a express bus, and the like, may also be obtained according to the need of the customer for the vehicle type, and the vehicle is filtered according to the vehicle type based on the need of the customer, so as to obtain the vehicle that meets the need of the customer.

As can be seen from the above, the present embodiment may display a map page, where the map page includes a map corresponding to the current location, and the map includes at least one geographic area and vehicle icons of vehicles around the current location; when the real-time geographic position of the vehicle is acquired, the vehicle icon in the map page is controlled to be displayed in a smooth moving mode from a starting geographic position to a target geographic position, wherein the target geographic position is a random position in a target geographic area, and the starting geographic position is determined based on the real-time geographic position of the vehicle. According to the method and the device, the moving track of the vehicle icon can be controlled based on the real-time geographic position of the vehicle and the random position in the target geographic area, and the moving track of the vehicle icon is not controlled based on the real track of the vehicle, so that the driving behavior of the vehicle does not need to be predicted, and the smooth moving display of the vehicle icon on the road on the map is facilitated.
