The specific implementation of the embodiments of the present application is further described below with reference to the accompanying drawings of the embodiments of the present application.

Example 1

Embodiment 1 of the present application provides a rendering method, which is applied to a rendering device. For ease of understanding, an application scenario of the rendering method provided by Embodiment 1 of the present application is described. Referring to FIG. 1 , FIG. 1 is Embodiment 1 of the present application. Provides a scene diagram of a rendering method. The scene shown in FIG. 1 includes an electronic device 101, and the electronic device 101 may be a device that executes the rendering method provided in Embodiment 1 of the present application, that is, a rendering device.

The electronic device 101 may be a terminal device such as a vehicle terminal, a smart phone, a tablet computer, or a notebook computer. The electronic device 101 can access the network, connect with the cloud through the network, and perform data exchange. In this application, the network includes a local area network (English: Local Area Network, LAN), a wide area network (English: Wide Area Network, WAN), mobile communication network ; Such as World Wide Web (English: World Wide Web, WWW), Long Term Evolution (English: Long Term Evolution, LTE) network, 2G network (English: 2th Generation Mobile Network), 3G network (English: 3th Generation Mobile Network), 5G network ( English: 5th Generation Mobile Network) and so on. The cloud may include various devices connected through a network, such as servers, relay devices, end-to-end (English: Device-to-Device, D2D) devices, and the like. Of course, this is only an exemplary description, which does not mean that the present application is limited thereto.

The rendering method provided by Embodiment 1 of the present application is described in detail with reference to the scene shown in FIG. 1 . It should be noted that FIG. 1 is only an application scenario of the rendering method provided by Embodiment 1 of the present application, which does not mean that the rendering method must be It is applied to the scene shown in FIG. 1, and can be specifically applied to electronic equipment. Referring to FIG. 2, FIG. 2 is a flowchart of a rendering method provided in Embodiment 1 of the present application, and the method includes the following steps:

Step 201: Obtain the positioning position and navigation route of the object to be navigated.

The object to be navigated can be a vehicle driven or taken by the user, or a terminal device held by the user. , GNSS) positioning module, or, determined in conjunction with network positioning services. For example, the positioning position of the vehicle is determined by the vehicle-mounted terminal. The navigation route is used to indicate the travel route planned for the user from the starting point to the ending point, and the starting point and the ending point can be set by the user.

Step 202 , according to the positioning position and the navigation route, obtain a target lane included in the target road that the navigation object will enter ahead of the positioning position of the navigation object.

The target road ahead of the object being navigated may indicate a road that is forward by a preset length in the driving direction from the positioning position according to the navigation route. The target road may include one or more target lanes. Optionally, in an implementation manner, the target lane may include all lanes in the target road that have the same direction of travel as the lane where the navigation object is located. For example, taking the lane where the positioning position is located as an example, the target road where the positioning position is located contains 8 lanes, lane ABCD is the same-direction lane, and lane EFGH is the same-direction lane segment. If the lane where the positioning position is located is lane A, then lane ABCD belong to the target lane. Or, in another implementation manner, the target lane segment includes a lane that the navigated object will enter along the navigation route within a set distance ahead of the positioning position according to the driving direction. It should be noted that the preset distance may be set according to actual conditions, for example, the preset length may be 10m, 20m, 100m, 500m, etc., which is not limited in this application.

Step 203: Determine the rendering parameters of the electronic map to be rendered according to the attributes of the target lane included in the target road and/or the navigation guidance action of the navigation route on the target lane.

The rendering parameter enables at least lane-level rendering elements in the electronic map to be rendered to be displayed within the field of view of the screen. The attributes of the target lane may indicate the shape, type, curvature, whether to connect the intersection, the location of the intersection, etc., where the shape of the lane may include continuous curves, ramps, winding bridges, and the like. The navigation guidance actions of the navigation route on the target lane may include going straight along the main road, turning, sharp turning, U-turn, and the like.

In the present application, the rendering parameters may include at least one of a scale, an orientation angle, and a top-down angle. It should be noted that the scale bar refers to the ratio of the distance on the map to the actual distance. The larger the scale bar, the smaller the range displayed on the electronic map and the clearer the details. In this application, the value range of the scale of the rendering parameter is different from that of the ordinary map, and the scale of the ordinary map needs to be adjusted in a wider range. Generally, the maximum value of the scale of the ordinary map is usually 1/200000 to 1/2500000 , that is, 1 cm on the map represents the actual distance of 2 kilometers, and 1 cm on the map represents the actual distance of 25 kilometers. In this application, the scale of the rendering parameter ranges from 1/2500 to 1/500. This The value range can include endpoints, that is, the scale value of the rendering parameter can be 1/2500 or 1/500; the direction angle refers to the angle between the front of the screen and the driving direction of the navigated object, and the front of the screen can be the screen. The direction extending from the lower edge to the upper edge; the overlooking angle refers to the angle between the direction in which the user views the electronic map and the horizontal plane in the electronic map. The viewing angle is 90 degrees.

Optionally, in an implementation manner, the adjustment of the rendering parameters is to give the driver a better observation field and better display the lane-level rendering elements. In this application, the observation field may include the observation direction and the field of view. Exemplarily, determining the rendering parameters of the electronic map to be rendered according to the attributes of the target lane included in the target road and/or the navigation guidance action of the navigation route on the target lane, including: according to the attributes of the target lane included in the target road and/or The navigation guidance action of the navigation route on the target lane, predicts the driver's target observation field of view of the electronic map, and the target field of view information is used to indicate the predicted driver's field of view and field of view direction; adjust the rendering parameters of the electronic map based on the target observation field of view , so that the actual observation field is close to the trend of the target observation field. It should be noted that the predicted target observation field of view is a field of vision suitable for the driver that matches the road conditions of the target road ahead. It adapts to the target road ahead. Therefore, the target observation field of view is obtained by prediction based on the target road, and the rendering parameters are adjusted so that the actual observation field of view changes toward the target observation field of view.

Optionally, four specific application scenarios are listed here to describe in detail how to adjust the rendering parameters.

Optionally, in the first application scenario, as shown in FIG. 3 , FIG. 3 is a schematic diagram of the display effect of an electronic map provided by Embodiment 1 of the present application, and the navigation guidance action of the navigation route on the target lane indicates that the target Driving straight in the lane can also be called forward driving, or driving along the main road in the target lane. In this application scenario, because of the straight driving, there is no need to observe the details of the electronic map, which can ensure a large observation field.

Exemplarily, as shown in FIG. 3 , the rendering parameters include a scale, and the rendering parameters of the electronic map to be rendered are determined according to the navigation guidance action of the navigation route on the target lane, including: when the navigation guidance action of the navigation route on the target lane is: If you drive straight along the target lane, reduce the scale, so that the length of the target lane displayed in the field of view of the screen reaches the preset distance value. After reducing the scale of the electronic map, the field of view of the actual observation field becomes larger, and the driver can see the road farther, which is convenient for driving. It should be noted that, here, the preset distance value may be set according to the actual situation, for example, the preset distance value may be 1km, 2km, 5km, 10km and so on.

Exemplarily, as shown in FIG. 3 , the rendering parameters include a direction angle and a top-down angle, and the rendering parameters of the electronic map to be rendered are determined according to the attributes of the target lane included in the target road and the navigation guidance action of the navigation route on the target lane, including: : According to the attributes of the target lane, it is determined that the curvature of the target lane is greater than the preset curvature threshold, and the navigation guidance action of the navigation route on the target lane is to go straight along the target lane, then adjust the direction angle in the rendering parameters according to the curvature of the target road, and Increase the top view angle in the rendering parameters so that the target lane is displayed within the field of view of the screen. It should be noted that the curvature of the target lane represents the degree of curvature of the target lane, and the angle between the tangent of the starting point of the target lane and the tangent of the end point can be used to represent the curvature of the target lane. The direction can be set to be deflected by a preset angle according to the direction of the target lane, which is equivalent to deflecting the front of the screen display relative to the direction of the navigation object’s driving direction according to the direction of the road curve. The preset angle is rotated in a direction opposite to the direction in which the target lane is curved. The preset angle can be set according to specific conditions, and the specific value of the preset angle is not limited in this application.

For example, if it is determined according to the attributes of the target lane that the target lane is a winding bridge/ramp with a curvature greater than a preset curvature threshold, the scale of the electronic map is reduced and the top-down angle is increased, so that the winding bridge/ramp included in the rendering element is fully More may be displayed in the display area of the screen. It should be noted that the deflection here is in a plane parallel to the ground, and the target lane has a large curvature, increasing the bird's-eye view angle, and making accurate judgments away from the driver's observation of the road shape.

It should also be noted that the examples in the first application scenario can be executed independently or combined to form a new solution, which is not limited in this application.

Optionally, in the second application scenario, as shown in FIG. 4 , which is a schematic diagram of the display effect of an electronic map provided in Embodiment 1 of the present application, the navigation guidance action of the navigation route on the target lane indicates that the target Turning at the intersection in front of the lane, because turning needs to show more road details, it is convenient for the driver to judge the positional relationship between the intersection ahead and the positioning position, and the scale can be increased. Exemplarily, the rendering parameters include a scale and a top-down angle, and the rendering parameters of the electronic map to be rendered are determined according to the navigation guidance action of the navigation route on the target lane, including: when the navigation guidance action of the navigation route on the target lane indicates that the navigation route is in the target lane When turning at the intersection ahead, increase the scale of the electronic map, and increase the top-down angle in the rendering parameters, so that the intersection ahead in the rendering element is displayed within the field of view of the screen. It should also be noted that, in an implementation manner, the scale of the electronic map may be gradually increased, and the top-down angle in the navigation viewing angle may be gradually increased during the process of the navigation object approaching the intersection ahead.

Further, in an example, the rendering parameters also include a direction angle, and determining the rendering parameters of the electronic map to be rendered includes: adjusting the direction angle in the rendering parameters according to the turning direction indicated by the navigation guidance action of the navigation route on the target lane. , so that the front intersection in the rendering element is displayed in the middle area of the screen's field of view. Optionally, the middle area of the field of view of the screen may be the area located in the middle of the field of view of the screen in the direction from left to right. As shown in FIG. 3 , the middle 70% area of the field of view of the screen is the middle area. The front intersection in the rendering element is adjusted to be displayed in the middle area, which is more helpful for the driver to judge the relative positional relationship between the positioning position and the intersection.

It should be noted that, in combination with the first application scenario, if the curvature of the target lane is greater than the preset curvature threshold, in the process of adjusting the direction angle, it is necessary to ensure that the front intersection is displayed in the middle area of the screen field of view.

Optionally, in a third application scenario, as shown in FIG. 5 , which is a schematic diagram of a display effect of an electronic map provided in Embodiment 1 of the present application, the rendering parameters include a scale, according to the size of the target lane included in the target road. attribute to determine the rendering parameters of the electronic map to be rendered, including: according to the attributes of the target lane included in the target road, when it is determined that the target lane is a dedicated lane for which driving is prohibited, increasing the scale to display the details of the dedicated lane within the field of view of the screen. Further optionally, if it is determined that the positioning position has deviated from the navigation route according to the navigation route and the navigation guidance action on the target lane, and the target road is determined to be a dedicated lane for which driving is prohibited according to the attributes of the target lane included in the target road, the rendering is increased. The scale bar in the parameters, and the violation prompts. Because the navigation route is pre-planned and does not pass through the special lane where driving is prohibited, if the object being guided deviates from the navigation route, it is necessary to determine whether the target lane is the special lane where driving is prohibited. Here, take the special lane where driving is prohibited as an example. Optionally, it can also be determined whether the positioning position is in the prohibited driving area. If the positioning position is in the prohibited driving area, increase the scale in the rendering parameters to display the details of the prohibited driving area. The user can be prompted. The prohibited driving area may include a dedicated lane where driving is prohibited, and may also include a roadside area where driving is prohibited, which are not listed here. Exemplarily, if the object to be navigated is an ordinary car, the non-motor vehicle lane, the bus-only lane, and the emergency lane belong to the exclusive lanes for which driving is prohibited; if the object to be navigated is a bicycle, the motor vehicle lane belongs to the exclusive lanes for which driving is prohibited. This is just an exemplary illustration, which does not mean that the present application is limited thereto.

Optionally, in the fourth application scenario, as shown in FIG. 6 , which is a schematic diagram of a display effect of an electronic map provided in Embodiment 1 of the present application, the rendering parameters include a scale, and according to the size of the target lane included in the target road Navigation and guidance actions of attributes and navigation routes on the target lane, and determining the rendering parameters of the electronic map to be rendered, including: according to the attributes of the target lane contained in the target road and the navigation and guidance actions of the navigation routes on the target lane, determining that there is a presence on the target lane When there are at least two consecutive intersections and the navigation guidance action of the navigation route on the target lane is turning, the scale is dynamically adjusted so that the turning actions of the at least two consecutive intersections are displayed within the field of view of the screen. For example, take the screen field of view to keep two turns as an example, if there are more than two turns within the screen field of view, increase the scale to display road details, and if the screen field of view has less than two intersections, reduce the scale , to increase the observation field, which not only ensures the display of road details, but also ensures a wider field of vision and improves driving safety. It should also be noted that here, taking at least two consecutive intersections as an example, if it is not an intersection but a continuous curve, the scale can also be dynamically adjusted to keep two corners within the field of view of the screen.

It should also be noted that, the above four application scenarios may be implemented independently, or may be arbitrarily combined, which is not limited in this application.

Step 204: Render the electronic map to be rendered according to the rendering parameters.

With reference to the rendering method described in the above steps 201-204, it should be noted that, in an example, the user can manually adjust the rendering parameters of the electronic map. Zoom out (decrease the scale) and zoom in (increase the scale), you can also slide the electronic map (adjust the field of view), and rotate the electronic map (adjust the direction angle and top-down angle). When the rendering device detects the user's operation of adjusting the rendering parameters, in response to the user's operation of adjusting the rendering parameters, it generates adjustment information of the rendering parameters, and exits the target lane according to the attributes of the target lane included in the target road and/or the navigation route on the target lane. The navigation guide action determines the rendering parameters of the electronic map to be rendered, adjusts the rendering parameters based on the adjustment information, and renders the electronic map based on the adjusted rendering parameters. When the user manually adjusts the rendering parameters (ie, adjusts the viewing field of view of the electronic map), the user's operation is the main thing. After the user's operation, if the user's operation of adjusting the rendering parameters is not detected within the preset time period, continue to determine the to-be-rendered according to the attributes of the target lane included in the target road and/or the navigation guidance action of the navigation route on the target lane The rendering parameters of the electronic map.

The rendering method provided by the embodiment of the present application obtains the positioning position and the navigation route of the object to be navigated; according to the positioning position and the navigation route, obtains the target lane included in the target road that the navigation object will enter ahead of the positioning position of the object to be navigated; The attributes of the target lane included in the target road and/or the navigation guidance action of the navigation route on the target lane, determine the rendering parameters of the electronic map to be rendered, and the rendering parameters at least make the lane-level rendering elements in the electronic map to be rendered displayed in the screen field of view inside; according to the rendering parameters, render the electronic map to be rendered. Because the rendering parameters are dynamically adjusted according to the target road ahead, the lane-level rendering elements of the target road are within the field of view of the screen, which satisfies the user's visual field requirements for browsing the electronic map and improves the navigation effect.
