SUMMARY

[0005] In order to solve the problems in the related art, the embodiments of the present disclosure provide an information prompting method, device, equipment and readable storage medium.

[0010] When the lane position range affected by the prompt information needs to be displayed, a region corresponding to the lane position range in the lane-level electronic map is rendered according to a preset rendering mode, so that the region and a lane not affected by the prompt information have a visual difference.

[0015] The rendering module is configured to, when the lane position range affected by the prompt information needs to be displayed, render a region corresponding to the lane position range in the lane-level electronic map according to a preset rendering mode, so that the region and a lane not affected by the prompt information have a visual difference.

[0032] The details of the embodiments of the present disclosure will be described in detail below through specific embodiments.

[0033] FIG. 1 shows a flowchart of an information prompting method according to an embodiment of the present disclosure. The method is applied to display prompt information to guide the traveling of a navigated object on a lane-level electronic map along a planned navigation route. As shown in FIG. 1, the information prompting method includes the following steps:

[0034] In step S101, prompt information related to the navigation route is obtained;

[0035] In step S102, according to the road segment carried by the prompt information and the matching relationship between the pre-generated road segment and lane segment, the lane segment corresponding to the road segment is determined;

[0036] The road segment carried by the prompt information refers to a road segment where the prompt information occurs; the matching relationship between the pre-generated road segment and lane segment refers to the matching relationship between the road segment and the lane segment included in the road segment; and the road position carried by the prompt information refers to the occurrence position of the prompt information in the road.

[0037] In step S103, according to the road position carried by the prompt information, the type of the prompt information and the lane information affected by the prompt information, the lane position range affected by the prompt information is determined in the lane segment corresponding to the road segment;

[0038] In step S104, when the lane position range affected by the prompt information needs to be displayed, the area corresponding to the lane position range in the lane-level electronic map is rendered according to a preset rendering mode, so as to make the area visually different from the lanes not affected by the prompt information.

[0039] In some embodiments, the information prompting method described above can be executed by a terminal loaded with application software with a navigation function, which can include a mobile terminal, a vehicle-mounted device (car machine), a wearable device, etc.

[0040] In some embodiments, the prompt information related to the navigation route can be understood as an event appearing in the navigation route that affects the travel of the object being navigated, which can include road construction, traffic accidents, road closure, etc.

[0041] In some embodiments, the step S101 of acquiring the prompt information related to the navigation route can be implemented as: periodically actively sending a request carrying the navigation route to a prompt information publisher, and receiving the prompt information related to the navigation route returned by the prompt information publisher in response to the request, wherein the prompt information publisher can be a terminal with a prompt information publishing function, or a prompt information publishing service running in the cloud. Alternatively, it can be implemented as: actively sending the navigation route to the prompt information publisher, and then passively receiving the prompt information related to the navigation route periodically sent by the prompt information publisher.

[0042] In some embodiments, the related features in step S103 can be understood as follows:

[0043] The prompt information type can be understood as the event type of the event prompted by the prompt information. For example, the prompt information type can include point events and line events. The line event can be understood as an event occurring within a certain length of the road, such as road construction, road facility maintenance, road cleaning, etc.; the point event can be understood as an event occurring at a certain position of the road, such as a traffic accident, etc.

[0044] The lane information affected by the prompt information can be understood as which lanes of the road segment where the prompt information is located are specifically affected by the event prompted by the prompt information. For example, the event prompted affects the first lane and the second lane of the road segment.

[0045] In some embodiments, the lane position range affected by the prompt information can be understood as an area that needs to be avoided during the process of the navigation object traveling along the planned navigation route. For example, if a traffic accident occurs on a road along the navigation route, the lane position range affected by the traffic accident can be obtained by extending a certain length upstream or downstream of the road along the lane affected by the traffic accident, with the road position of the traffic accident as the reference, on the lane segment of the road segment corresponding to the traffic accident.

[0046] In some embodiments, the step S104 of determining whether the lane position range affected by the prompt information needs to be displayed can be determined by the distance between the real-time position of the navigation object and the road position carried by the prompt information. When the distance is less than a preset distance threshold, it is determined that the lane position range affected by the prompt information needs to be displayed. Alternatively, the distance between the real-time position of the navigation object and the road position carried by the prompt information, and the average speed of the navigation object, can be used to obtain the time when the navigation object passes through the road position. If the time difference between the current time and the passing time is less than or equal to a preset time threshold, it is determined that the lane position range affected by the prompt information needs to be displayed.

[0047] In some embodiments, the area corresponding to the lane position range in the lane-level electronic map is rendered according to a preset rendering mode to make the area visually different from the lane not affected by the prompt information. It can be understood that the area corresponding to the lane position range in the lane-level electronic map and the area of the lane not affected by the prompt information except for the area are rendered according to different texture data, so that the two areas after rendering can have visual differences when displayed in the electronic map. Alternatively, when rendering the two areas, at least one of the gray scale, brightness, contrast, and saturation of the two areas is ensured to have a certain difference, so that the two areas after rendering can have visual differences when displayed in the electronic map.

[0048] For example, when rendering the guide surface guiding the navigation object to travel along the navigation route in the lane-level electronic map, the guide surface can cover the area of the lane not affected by the prompt information, but not cover the area of the lane affected by the prompt information, so that the area of the lane affected by the prompt information and the area of the lane not affected by the prompt information have obvious visual differences.

[0049] FIG. 2 shows a display interface schematic diagram of application software with a navigation function according to an embodiment of the present disclosure. In order to facilitate understanding of the implementation effect of the solution provided by the present disclosure, the following exemplary description is made in conjunction with FIG. 2:

[0050] As shown in FIG. 2, in the interface 200 of the application software with the navigation function, a lane-level electronic map is displayed, wherein the lane segments corresponding to the road segment (the part of the road corresponding to the two dashed lines) carrying the prompt information include lane segment 201, lane segment 202, lane segment 203 and lane segment 204. According to the road position carrying the prompt information, the prompt information type and the lane information affected by the prompt information, the lane position range 205 affected by the prompt information is determined in the lane segment corresponding to the road segment carrying the prompt information, as shown in the shaded part in FIG. 2, the lane position range 205 covers part of the lane segment 201 and the lane segment 202. When the lane position range affected by the prompt information needs to be displayed, the lane position range 205 is rendered according to the preset rendering mode, so that the display effect of the lane position range 205 is visually different from the lane segments (such as the lane segment 203 and the lane segment 204) not affected by the prompt information.

[0051] In the information prompt method provided in the embodiments of the present disclosure, since the lane position range affected by the prompt information can be understood as an area that needs to be avoided according to the prompt information during the navigation object travels along the planned navigation route, when the lane position range affected by the prompt information needs to be displayed, the corresponding area of the lane position range in the lane-level electronic map is rendered according to the preset rendering mode, so that the area is visually different from the lane not affected by the prompt information, which can enable the user to accurately know the area that needs to be avoided when traveling along the navigation route by viewing the graphic display information, thereby helping the user to predict the road traffic situation and drive safely, and improving the user experience.

[0052] In an optional implementation of the embodiment, the lane position range affected by the prompt information is determined in the lane segment corresponding to the road segment according to the road position carrying the prompt information, the prompt information type and the lane information affected by the prompt information, including:

[0053] The road position carrying the prompt information is projected in the lane segment corresponding to the road segment, and the projection position is determined as the starting position of the lane affected by the prompt information;

[0054] According to the prompt information type, the length of the lane affected by the prompt information is obtained;

[0055] Starting from the starting position of the lane, the length of the lane is advanced along the travel direction of the lane segment to obtain the ending position of the lane affected by the prompt information;

[0056] According to the starting position of the lane, the ending position of the lane and the lane information affected by the prompt information, the lane position range affected by the prompt information is determined in the lane segment corresponding to the road segment.

[0057] In an optional implementation of the embodiment, the lane length affected by the prompt information according to the prompt information type can be understood as determining the lane length corresponding to the prompt information type according to a lane length matching relationship file pre-acquired, wherein the lane length matching relationship file is used to indicate the corresponding relationship between the prompt information type and the lane length. Alternatively, the lane length affected by the prompt information can also be extracted from the corresponding position in the prompt information according to the prompt information type.

[0058] For example, as shown in FIG. 2, the road position carrying the prompt information is projected in the lane segment corresponding to the road segment, and the projection position is determined as the lane start position 206 affected by the prompt information. According to the prompt information type, the lane length affected by the prompt information can be acquired, and it is assumed to be 500 meters. Then, the lane end position 207 affected by the prompt information can be obtained by advancing 500 meters along the travel direction of the lane segment from the lane start position 206. According to the lane start position 206, the lane end position 207, and the lane information (such as the lane segment 201 and the lane segment 202) affected by the prompt information, the lane position range 205 affected by the prompt information can be determined in the lane segment corresponding to the road segment.

[0059] In the optional implementation, considering that the lengths (distances) affected by different events in the corresponding lane are different, in order to enable the user to more accurately determine the area that needs to be avoided when traveling along the navigation route, the lane length corresponding to the prompt information type can be determined according to the lane length matching relationship file pre-acquired.

[0060] In an optional implementation of the embodiment, the lane length affected by the prompt information according to the prompt information type includes:

[0061] If the prompt information type belongs to the line event type, the lane length affected by the prompt information is extracted from the prompt information.

[0062] If the prompt information type belongs to the point event type, the lane length affected by the prompt information is acquired from the corresponding relationship between the point event type and the lane length pre-generated.

[0063] In an optional implementation of the embodiment, the lane length affected by the prompt information is extracted from the prompt information, which can be understood as that the prompt information carries the lane length affected by the prompt information.

[0064] In the optional implementation, the length of the lane affected by the line event type is often different based on the field situation, and the lane length corresponding to the line event type cannot be determined in advance, therefore, the lane length can be dynamically determined by the prompt information publisher according to the prompt information, and the determined lane length is carried in the prompt information for publishing; the length of the lane affected by the point event type often has certain rules, and therefore the lane length corresponding to the point event type can be pre-configured, and therefore when the prompt information type belongs to the point event type, the lane length affected by the prompt information can be obtained from the pre-generated corresponding relationship between the point event type and the lane length. The implementation scheme ensures the accuracy of the lane length affected by the prompt information in the case of reducing the complexity.

[0065] In an optional implementation of the embodiment, according to the lane start position, the lane end position and the lane information affected by the prompt information, the lane position range affected by the prompt information is determined in the lane section corresponding to the road section, including:

[0066] Based on the lane information affected by the prompt information, the lane section affected by the prompt information is determined as the target lane section in the lane section corresponding to the road section;

[0067] The part between the lane start position and the lane end position in the target lane section is determined as the lane position range affected by the prompt information.

[0068] For example, as shown in FIG. 2, the lane section corresponding to the road section includes lane section 201, lane section 202, lane section 203 and lane section 204; if lane section 201 and lane section 202 are determined to be affected based on the lane information affected by the prompt information, lane section 201 and lane section 202 can be determined as the target lane section. The part between the lane start position 206 and the lane end position 207 in lane section 201 and lane section 202 can be determined as the lane position range 205 affected by the prompt information.

[0069] For example, as shown in FIG. 2, the road position carried by the prompt information is projected in the lane section corresponding to the road section, and the projection position is determined as the lane middle position affected by the prompt information; according to the prompt information type, the lane length affected by the prompt information can be obtained, which is assumed to be 500 meters, then 250 meters is advanced along the travel direction of the lane section from the lane middle position to obtain the lane end position 207 affected by the prompt information, and 250 meters is advanced against the travel direction of the lane section to obtain the lane start position 206 affected by the prompt information; according to the lane start position 206, the lane end position 207 and the lane information affected by the prompt information (such as lane 201 and lane 202), the lane position range 205 affected by the prompt information can be determined in the lane section corresponding to the road section.

[0070] The aforementioned projection position can be any reference position within the lane position range according to actual needs of those skilled in the art, and the present disclosure does not make any limitation, and the aforementioned examples are only provided to more clearly illustrate the embodiments of the present disclosure, and should not be regarded as a limitation of the present disclosure.

[0071] In this optional implementation, the accuracy of the lane position range affected by the prompt information can be further improved.

[0072] In an optional implementation of the present embodiment, according to the lane start position, the lane end position and the lane information affected by the prompt information, the lane position range affected by the prompt information is determined in the lane section corresponding to the road section, comprising:

[0073] The lane affected by the prompt information is determined in the lane section corresponding to the road section according to the lane information affected by the prompt information.

[0074] If the navigated object does not pass through the lane affected by the prompt information, the lane position range affected by the prompt information is determined on the lane affected by the prompt information according to the lane start position and the lane end position.

[0075] In this optional implementation, if the navigated object has passed through the lane affected by the prompt information, the navigated object does not need to accept the prompt of the prompt information, so by determining the lane position range affected by the prompt information on the lane affected by the prompt information when the navigated object does not pass through the lane affected by the prompt information, the required data processing resources can be reduced and the cost can be reduced on the premise of ensuring that the user can get timely prompt.

[0076] In an optional implementation of the present embodiment, the method further comprises:

[0077] The driving lane of the navigated object is determined based on the real-time positioning position of the navigated object.

[0078] If the lane section affected by the prompt information is located on the driving lane, the lane section not affected by the prompt information is determined as the guide lane section in the lane section corresponding to the road section based on the lane information affected by the prompt information.

[0079] The merging position for guiding the navigated object to merge into the guide lane section is determined by starting from the lane start position affected by the prompt information and traveling a preset merging safety distance in the opposite direction of the driving direction of the driving lane.

[0080] When the distance between the real-time positioning position of the navigated object and the merging position is less than a preset guide distance threshold, the merging guide information is played to guide the navigated object to enter the guide lane section from the driving lane.

[0081] In some embodiments, the announcement of the lane guiding information can be a voice played through a speaker to guide the navigated object to enter the guiding lane segment from the driving lane; or can be an image, text or symbol rendered in the lane-level electronic map to guide the navigated object to enter the guiding lane segment from the driving lane.

[0082] FIG. 3 shows a schematic diagram of a display interface of the application software with the navigation function according to another embodiment of the present disclosure. To facilitate understanding of the scheme provided in the embodiments of the present disclosure, the following exemplary description is made in conjunction with FIG. 3:

[0083] As shown in FIG. 3, in the display interface 300 of the application software with the navigation function, a lane-level electronic map, a navigated object 301 and a lane position range 320 affected by the prompt information can be displayed. The driving lane 302 of the navigated object 301 can be determined based on the real-time positioning position of the navigated object 301. Since the lane segment affected by the prompt information includes the lane segment 303 and the lane segment 304, and the lane segment 304 is located on the driving lane 302, based on the lane information affected by the prompt information, the lane segment 305 and the lane segment 306 that are not affected by the prompt information are determined as the guiding lane segments in the lane segments 303, 304, 305 and 306 corresponding to the road segment. Starting from the lane start position 307 affected by the prompt information, a preset merging safety distance (assumed to be 300 meters) is traveled in the opposite direction of the driving direction 308 of the driving lane 302 to determine the merging position 309. When the distance between the real-time positioning position of the navigated object 302 and the merging position 309 is less than a preset guiding distance threshold (assumed to be 200 meters), a guiding symbol 310 is rendered in the lane-level electronic map to guide the navigated object 301 to enter the lane segment 305 or the lane segment 306 from the driving lane 302 along the guiding symbol 310.

[0084] In this optional implementation, the navigated object can be more smoothly guided to enter the guiding lane segment from the driving lane to avoid the lane segment affected by the prompt information, thereby avoiding the impact on the normal travel of the navigated object and improving the user experience.

[0085] In one optional implementation of the present embodiment, the method further includes:

[0086] determining whether the prompt information meets the requirements of the lane-level matching based on the event confidence carried in the prompt information and the visible lane information;

[0087] determining the lane segment corresponding to the road segment according to the road segment carried in the prompt information and the pre-generated matching relationship between the road segment and the lane segment, including:

[0088] If it is determined that the prompt information meets the requirement of the lane-level matching, a lane segment corresponding to the road segment is determined according to the road segment and the matching relationship carried by the prompt information.

[0089] In some embodiments, the event confidence can be used to indicate the confidence of a prompt information producer, which can be a prompt information publisher. The lane visibility information refers to whether the lane segment corresponding to the road segment carried by the prompt information is visible in the road image based on which the prompt information is generated.

[0090] In some embodiments, determining whether the prompt information meets the requirement of the lane-level matching can include:

[0091] If the event confidence is greater than or equal to a preset confidence threshold, and it is determined according to the lane visibility information that the lane segments corresponding to the road segments carried by the prompt information are all visible in the road image used to generate the prompt information, it is determined that the prompt information meets the requirement of the lane-level matching.

[0092] If the event confidence is greater than or equal to a preset confidence threshold, it can be considered that the confidence of the prompt information producer is high, thereby ensuring that the accuracy of the prompt information is high. If it is determined according to the lane visibility information that the lane segments corresponding to the road segments carried by the prompt information are all visible in the road image used to generate the prompt information, thereby ensuring that the accuracy of the prompt information generated based on the road image is high.

[0093] In this optional implementation, if it is determined based on the event confidence carried in the prompt information and the visible lane information that the prompt information meets the requirement of the lane-level matching, it can be ensured that the accuracy of the prompt information is high. At this time, by determining the lane segment corresponding to the road segment according to the road segment and the matching relationship carried by the prompt information, the accuracy of the determined lane segment corresponding to the road segment can be further improved.

[0094] The following is an apparatus embodiment of the present disclosure, which can be used to execute the method embodiments of the present disclosure.

[0095] FIG. 4 shows a structural block diagram of an information prompting apparatus according to an embodiment of the present disclosure.

[0099] The rendering module 404 is configured to render the area corresponding to the lane position range affected by the prompt information in the lane-level electronic map according to a preset rendering mode when the lane position range affected by the prompt information needs to be displayed, so as to cause a visual difference between the area and the lane not affected by the prompt information.

[0100] In the scheme proposed in the embodiments of the present disclosure, since the lane position range affected by the prompt information can be understood as an area that needs to be avoided according to the prompt of the prompt information in the process of the navigation object traveling along the planned navigation route, when the lane position range affected by the prompt information needs to be displayed, the area corresponding to the lane position range in the lane-level electronic map is rendered according to a preset rendering mode to cause a visual difference between the area and the lane not affected by the prompt information, so that the user can accurately know the area that needs to be avoided when traveling along the navigation route by viewing the graphic display information, thereby helping the user to predict the road traffic condition and drive safely, and improving the user experience.
