[0045] The method for displaying the smooth movement of the vehicle position provided by the embodiment of the present application can be applied to Figure 1 In the system architecture shown in Figure 1 As shown, the vehicle navigation system may include: a server and a terminal; wherein the server may be a physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), as well as basic cloud computing services such as big data and artificial intelligence platforms.

[0046] Specifically, the terminal includes a data acquisition component, a path planning component, and a visualization interface;
[0047] A data collection component for a road network on which the driving path is located, as well as a first vehicle position of the target vehicle at a current moment and a second vehicle position at a moment before the current moment; wherein the road network includes a prohibited area;
[0048] a path planning component for determining a target path from the second vehicle position to the first vehicle position; using the second vehicle position as a starting point of the target path, and determining whether a next point of the starting point is within a restricted area;
[0049] An animation control component is used to control the transparent icon to move from the starting position point to the next position point along the target path when the next position point is not located in the prohibited area; and after the transparent icon is controlled to move from the starting position point to the next position point along the target path, control the vehicle icon to move from the starting position point to the next position point along the target path;

[0056] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.
[0057] Figure 2This is a flow chart of a method for displaying the smooth movement of a vehicle position provided by an embodiment of the present application. Figure 2 As shown, when applied to a scenario with sparse vehicle locations, the method may include:
[0058] Step S210: Acquire the road network where the driving path is located, as well as the first vehicle position of the target vehicle at the current moment and the second vehicle position at the moment before the current moment.
[0059] Among them, the road network contains at least one restricted area; restricted areas are areas where buildings are located or other areas that are inaccessible (such as crosswalks or bus lanes); the road network also includes the geometric shape and type of roads, the connection relationship between roads, lane information and intersection details, etc.; road types include main roads, secondary roads and one-way streets, etc.
[0060] In a specific implementation, the first vehicle position and the second vehicle position are diluted vehicle positions, and a method for obtaining the first vehicle position and the second vehicle position includes:
[0061] A first initial position of the target vehicle at the current moment and a second initial position of the target vehicle at the moment before the current moment are obtained by asynchronous acquisition; the first initial position and the second initial position are converted into a first vehicle position and a second vehicle position in a geographic coordinate system; wherein the first initial position and the second initial position are the positions of the target vehicle in a global positioning coordinate system.
[0062] Specifically, the first initial position of the vehicle at the current moment and the second initial position of the target vehicle at the previous moment are obtained by sending an HTTP request to the server through the network service interface and receiving the data returned by the server in an asynchronous manner; the server can be Amap or other servers; the data returned by the server is the position in the GPS global coordinate system; therefore, a coordinate system conversion is required to convert the coordinate systems of the first initial position and the second initial position into the standard map coordinate system, i.e., the geographic coordinate system.
[0063] Step S220: Determine a target path from the second vehicle position to the first vehicle position.
[0064] In a specific implementation, multiple paths from the second vehicle position to the first vehicle position are determined; the starting point of each path is the second vehicle position; the ending point of each path is the first vehicle position; each path contains multiple points, each of which may be located in a restricted area; and the shortest straight line path is selected from the multiple paths as the target path.
[0065] The target path is divided into a plurality of position points according to a configured length. For example, if the first vehicle position and the second vehicle position are 20 meters apart, the target path can be divided into five position points with a length of 5 meters.
[0066] Step S230: Taking the second vehicle position as the starting position of the target path, determining whether the next position of the starting position is located in the prohibited area.
[0067] In the specific implementation, after the starting position point is determined, the transparent icon and the vehicle icon are controlled to move to the starting position point; according to the location of each prohibited area in the road network, it is determined whether the next position point of the starting position point is a prohibited area; the determination of whether the next position point of the starting position point is a proceeding area is to determine whether the vehicle icon can move from the starting position point to the next position point according to the target path; for example, when the next position point of the starting position point is in a prohibited area, the vehicle icon directly moves from the starting position point to the next position point, and there will be phenomena such as passing through buildings.
[0068] Step S240: Determine the moving path of the vehicle icon and the moving path of the vehicle icon displayed on the visual interface according to whether the next location point is located in the prohibited area.
[0069] In a specific implementation, the moving path of the vehicle icon is determined based on whether the next location point is located in the prohibited area, including:
[0070] (1) If the next position point is not located in the prohibited area, the target path is used as the moving path of the vehicle icon, and the transparent icon is controlled to move from the starting position point to the next position point along the target path; then, the smooth movement process of the vehicle icon from the starting position point to the next position point is displayed on the visual interface; the next position point is used as the new starting position point, and the execution step is returned to: the transparent icon is controlled to move from the starting position point to the next position point along the target path until the vehicle icon is displayed at the first vehicle position on the visual interface; wherein, the transparent icon first moves to the next position point, and the next position point is used as the new starting position point, and it is determined whether the new next position point of the new starting position point is located in the prohibited area. If not, the transparent icon is controlled to move from the new starting position point to the new next position point, and the vehicle icon is controlled to move from the starting position point to the next position point at the same time; that is, the movement process of the transparent icon and the vehicle icon is not synchronized, but the transparent icon is one position point ahead of the vehicle icon; the transparent icon is a virtual "ferryman" mark created for path exploration; the vehicle icon moves smoothly along the path traveled by the transparent icon, which is used to show the terminal user the location and movement process of the vehicle.
[0071] (2) If the next position point is located in the prohibited area, the target path is not the moving path of the vehicle icon, and a new target path (i.e., the moving path of the vehicle icon) is replanned from the starting position point to the first vehicle position, and the execution step is returned to: determining whether the next position point of the starting position point is located in the prohibited area, until the vehicle icon is displayed at the first vehicle position on the visual interface; wherein, when the next position point is located in the prohibited area, it means that it is currently impossible to move from the starting position point to the next position point; therefore, the transparent icon needs to explore other feasible paths, i.e., replan a new target path from the starting position point to the first vehicle position, and the replanned path may be one or more. When there are multiple paths, the one with the shortest distance can be selected; the new target path is different from the original target path.
[0072] In some embodiments of the present application, replanning a new target path from the starting position to the first vehicle position includes:
[0073] Extracting a target road segment from the road network based on the starting location and the first vehicle position; the target road segment includes the starting location, the first vehicle position, and corresponding adjacent areas; analyzing the target road segment to determine the geometry and type of each road in the target road segment, the connectivity between the roads, and lane information; searching for target lane information moving from the starting location to the first vehicle position in the target road segment using a graph search algorithm (such as a Dijkstra algorithm or an A* algorithm) based on the geometry and type of each road in the target road segment, the connectivity between the roads, and the lane information; and adjusting the target lane information based on configured traffic status data to obtain a new target path.
[0074] The traffic status data includes information such as temporary traffic control and road construction. The target lane information is adjusted based on the configured traffic status data, including determining whether traffic status data related to the target lane information exists; if not, using the target lane information as a new target path; if so, returning to the execution step based on the traffic status data: adjusting the geometry and type of each road in the target road segment, the connection relationship between the roads, and the lane information until a new target path is obtained.
[0075] This application creates a transparent icon that is invisible to the end user to correct the straight line across the building caused by the large span of vehicle location density into a curved path for rolling road.
[0076] In actual application, a ferry path including multiple ferry location points is generated according to the moving path of the transparent icon; and the vehicle icon moves forward along the ferry path.
[0077] In a specific implementation, the smooth movement process of the vehicle icon from the second vehicle position to the first vehicle position is displayed on the visual interface; the movement path of the vehicle icon displayed on the visual interface includes:
[0078] Determine the target moving speed based on the distance between the first vehicle position and the second vehicle position; wherein, when the distance between the first vehicle position and the second vehicle position is greater than the configured distance threshold, the ratio of the distance and the configured first time length is used as the target moving speed; when the distance between the first vehicle position and the second vehicle position is not greater than the configured distance threshold, the ratio of the distance and the configured second time length is used as the target moving speed; wherein, the distance threshold, the first time length and the second time length are user-defined, and the distance threshold may be 20 meters; the first time length may be 200 milliseconds; and the second time length may be 40 milliseconds; in other embodiments of the present application, the distance threshold may be user-defined, and the first time length and the second time length are both the time length difference between the current moment and the moment before the current moment; or the first time length and the second time length are both the time length difference between the current moment and the moment predicted to be next to the current moment;
[0079] The visual interface shows the smooth movement process of the vehicle icon from the starting position to the next position at the target moving speed.
[0080] In another embodiment of the present application, a road network corresponds to a road network type, and the road network types include urban roads, rural roads and highways; the distance threshold, the first duration and the second duration can be determined according to the target application scenario of the display method for smooth movement of the vehicle position or the type of the road network, and the distance threshold, the first duration and the second duration corresponding to the type of the road network are matched from the configured comparison table of different road network types and different distance thresholds, different first durations and different second durations; for example, when applied to urban roads, the distance threshold is 10 meters, and the first duration and the second duration are 300 milliseconds and 60 milliseconds respectively; when applied to highways, the distance threshold is 50 meters, so that it moves at different target moving speeds according to different target application scenarios or different road network types; it is displayed more frequently in urban roads, and the frequent animation is reduced in scenarios such as highways where sensitive display is not required.
[0081] In the embodiment of the present application, a target moving speed is determined based on the distance between the first vehicle position and the second vehicle position, so that the vehicle icon moves quickly when the distance is large and moves smoothly when the distance is small.
[0082] In some embodiments of the present application, after the target vehicle moves from the first vehicle position to the second vehicle position, the moving path of the target vehicle is stored in the configured vehicle path library; the moving path includes the various position points passed by the target vehicle; the vehicle path library stores different moving paths of different target vehicles, and the moving paths are all real paths that conform to actual road conditions; therefore, when the method of the present application is implemented again, the corresponding target path can be matched from the vehicle path library according to the first vehicle position and the second vehicle position, and the transparent icon can be controlled to move according to the target path. If the target path does not pass through the prohibited area, the vehicle icon is controlled to move smoothly according to the target path, and the smooth movement process of the vehicle icon is displayed on the visual interface.
[0083] In other embodiments of the present application, the method also includes: obtaining the estimated completion time and remaining distance for the target vehicle to complete the driving route; displaying the estimated completion time and remaining distance on a visual interface; wherein the estimated completion time and remaining distance for the target vehicle to complete the driving route is obtained by sending an HTTP request to the server through a network service interface and receiving data returned by the server in an asynchronous manner; the server may be Amap or other servers.
[0084] In other embodiments of the present application, the method also includes: when the distance between the first vehicle position and the second vehicle position is greater than the configured critical distance, controlling the transparent icon and the vehicle icon to move directly from the second vehicle position to the first vehicle position; for example, when the distance between the first vehicle position and the second vehicle position exceeds 500 meters, the smooth movement of the vehicle icon cannot be completed in a short time or before the next vehicle position is obtained, so the transparent icon and the vehicle icon are directly moved from the second vehicle position to the first vehicle position.
[0085] In some embodiments of the present application, the method includes:
[0086] Create a marker ( myCarMarker ) that represents the car's location, using a specific icon ( carIcon ) that is the vehicle icon; and set the offset ( offset ), autorotation ( autoRotation ), and angle ( angle ) properties to ensure the icon is displayed in the correct orientation.
[0087] Create another marker named "ferryman" (followMarker), which is a transparent icon that is invisible to the user and is used to assist in handling path problems caused by a large span of driver coordinate point density;
[0088] Use the search method (search) provided by the AutoNavi Maps plug-in to generate a route based on the driver's previous location (preDriverLocation) and current location (driverLocation). If the search is successful, update the driver's location and parse the route (parseRouteToPath) for the ferryman (followMarker) to move along the route. As the ferryman moves, listen for its movement events (moving). Whenever the driving distance exceeds 10 meters, re-plan the route starting point to the current ferryman's location and call the driving route search function (Driving.search) again to update the route.
[0089] Calculate the distance between the current driver's location and the last location (nextCarLocationDistance); adjust the movement speed based on the distance: if the distance is greater than 20 meters, quickly jump to the new location; otherwise, move at a slower speed (for example, simulating 200 km / h); update the last car location record and move the car marker (myCarMarker) and label (carLabel) to the new route starting point; parse and format the remaining distance (lastDistance) and time (lastDuration), and update this information on the interface. When the remaining time is less than 50 seconds, the driver is determined to have arrived at the destination and the arrival operation is performed: this includes removing the original car label, adding a new arrival label, moving the car marker to the target location, and stopping the movement animation.
[0090] This application proposes the innovative concept of a dual-role navigation system. Through the cooperation of visible vehicle icons and invisible transparent icons (ferrymen), an intelligent path planning trigger mechanism based on distance thresholds is developed, and an adaptive vehicle movement speed control algorithm is designed to realize diversified information display methods for trip status perception.
[0091] Corresponding to the above method, the embodiment of the present application also provides a display device for smoothly moving the vehicle position, such as Figure 3 As shown, the device includes:
