Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
At present, in order to realize that all road segments included in a navigation route determined for a user are available road segments, an operator needs to collect road data, determine an unavailable road segment according to the road data collected by the operator, update road network data, and determine a navigation route based on the new road network data.
However, the operator has a certain collection period according to the collected road data, for example, for some remote road segments, the collection period may reach 1 month or half a year, and when the collection period for the operator to collect the road data is long, the operator may not know the unavailable road segments in the road network data in time, which may cause the problem of incorrect navigation route.
Based on the above problems, embodiments of the present invention provide a navigation method, apparatus, device, and storage medium, in which an unavailable route including an unavailable road segment in a to-be-determined navigation route is replaced with a target trajectory route to obtain a target navigation route, where the unavailable route is determined according to user trajectory data, and in a case where an acquisition cycle of an operator acquiring road data is long, the unavailable route including the unavailable road segment can be determined according to the user trajectory data, and a navigation route that does not include the unavailable road segment is provided to the user, so that accuracy of the navigation route is improved.
Fig. 1 is a flowchart of a navigation method according to an embodiment of the present invention. The execution main body of the method of the embodiment may be any navigation device that can implement a navigation function, for example, a navigator, a navigation mobile phone, and the like. As shown in fig. 1, the method of this embodiment may include:
step 101, after determining a route to be planned, judging whether the route to be planned contains an unavailable route.
In this step, the unavailable route may be a route determined according to the user trajectory data, and the first location to the second location include the unavailable road segment. The user trajectory data may specifically be trajectory data of the user when walking or driving within a recent period of time, which may be, for example, the last 7 days, the last 1 month, and the like. The unavailable road section may specifically refer to a road section which cannot be passed by the user, for example, the road section cannot be passed by the user due to road sealing construction.
Here, the determining of the route to be planned may specifically be a planned route determined according to the starting position, the ending position, and the road network data of the user. The user can choose to pass by walking between the starting position and the ending position or drive by driving. Optionally, when the walking mode is selected for passing, the user trajectory data may specifically be trajectory data of the user during walking; when the driving mode is selected, the user trajectory data may be trajectory data of a user during driving.
The first position and the second position may be preset positions or positions determined based on user trajectory data.
And step 102, if the to-be-planned route comprises an unavailable route, replacing the unavailable route in the to-be-planned route with a target track route from a first position to a second position to obtain a target planned route.
In this step, when the determined route to be planned includes an unavailable route according to the starting point position, the ending point position and the road network data of the user, it may be indicated that a road section which cannot be passed exists in the route to be planned, and the user cannot complete the passing according to the route to be planned, that is, the route to be planned is incorrect. Furthermore, the target planning route is obtained by replacing the unavailable route in the route to be planned with the target track route from the first position to the second position, and the user can finish passing according to the target planning route, namely the target planning route is correct. Optionally, after the target planned route is obtained, the user may be prompted with the target planned route.
When the determined to-be-planned route does not contain an unavailable route according to the starting point position, the end point position and the road network data of the user, the fact that no section which cannot be passed through exists in the to-be-planned route can be shown, the user can finish passing through the to-be-planned route, namely the to-be-planned route is correct, and therefore partial routes in the to-be-planned route can not be replaced. Optionally, after determining that the route to be planned does not include an unavailable route, the route to be planned may be prompted to the user. Or, optionally, after determining that the route to be planned does not include the unavailable route, performing other processing (for example, replacing a first available route in the route to be planned with a second available route) on the route to be planned except replacing the unavailable route in the route to be planned with the target trajectory route, and prompting the user with the processed route, which is not limited in this embodiment of the present invention.
It should be noted that the number of the unavailable routes in the route to be planned may be one or more, which is not limited in the present invention.
According to the navigation method provided by the embodiment, after the route to be planned is determined, whether the route to be planned contains an unavailable route or not is judged, if the route to be planned contains the unavailable route, the unavailable route in the route to be planned is replaced by the target track route from the first position to the second position, the target planned route is obtained, under the condition that the acquisition period of the road data acquired by the operating personnel is long, the unavailable route containing the unavailable road section can be determined according to the user track data, the navigation route without the unavailable road section is provided for the user, and the accuracy of the navigation route is improved.
Fig. 2 is a flowchart of a navigation method according to another embodiment of the present invention. The method of this embodiment is based on the embodiment of the method shown in fig. 1, and mainly describes an alternative implementation manner of determining an unavailable route according to user trajectory data. As shown in fig. 2, the method of this embodiment may include:
step 201, determining all track routes from the first position to the second position according to the user track data.
In this step, all the tracks passing through the first position and the second position may be obtained, and the track routes from the first position to the second position are respectively intercepted from all the tracks, so as to obtain all the track routes from the first position to the second position. It should be noted that the user trajectory data in step 201 may be user trajectory data within a last preset time length range.
Step 202, determine whether the specific route from the planned first location to the planned second location is included in all the tracks.
In this step, when the specific route is included in all the trajectory routes determined in step 202, it may indicate that the specific route is an available route, and thus, the process may be ended. When the specific route is not included in all the trajectory routes, it may indicate that the specific route may be an unavailable route, and further determination may be made to determine whether the specific route is an unavailable route, so step 203 may be further performed. Alternatively, when the specific route is not included in all the trajectory routes, the specific route may be represented as an unavailable route.
Step 203, judging whether the specific route comprises a road section with the track quantity smaller than or equal to a preset track quantity threshold value.
In this step, it is considered that although the reason that the specific route is not included in all the trajectory routes may be that the specific route is not good, no user moves from the first position to the second position according to the specific route, and therefore it may be further determined whether the specific route is an unavailable route according to the trajectory amount of the section included in the specific route. When the specific route does not include the road segment with the track quantity smaller than or equal to the preset track quantity threshold value, it can be indicated that all the road segments in the specific route are available road segments, and therefore the process can be finished. When the specific route includes a road segment with a track quantity smaller than or equal to the preset track quantity threshold value, and a road segment with a track quantity smaller than or equal to the preset track quantity threshold value can be understood as an unavailable road segment, it can be indicated that the specific route includes an unavailable road segment, and the specific route is an unavailable route.
It should be noted that step 203 may also precede step 202. Specifically, step 203 may be performed first to determine whether the specific route includes a road segment whose track amount is less than or equal to a preset track amount threshold. If the specific route includes the road segments with the track quantity smaller than or equal to the preset track quantity threshold, step 202 is executed to determine whether the specific route is included in all the tracks. If the specific route is included in all the tracks, the process may be ended. If the specific route is not included in all the tracks, the specific route is an unavailable route. If the specific route does not include the road sections with the track quantity smaller than or equal to the preset track quantity threshold value, the operation can be finished.
Alternatively, when the specific route is an unavailable route, further, the target trajectory route may be determined by the following step 203.
And 204, selecting a target track route from all the track routes according to the track quantity of each track in all the track routes.
In this step, optionally, the trajectory route with the largest trajectory quantity in all the trajectory routes may be selected as the target trajectory route according to the trajectory quantities of all the trajectories in all the trajectory routes determined in step 202; alternatively, the trajectories with the trajectory quantity greater than or equal to the preset threshold value may be determined according to the trajectory quantity of each trajectory in all the trajectories, and one trajectory route may be randomly selected as the target trajectory route from the trajectories with the trajectory quantity greater than the preset threshold value.
Alternatively, the specific route may be determined based on the user trajectory data, or may also be determined based on preset first and second locations and a historically planned route. When the specific route is determined from the user trajectory data, step 202 may be preceded by step 205 as follows.
Step 205, determining a specific route according to the user trajectory data and the historical planned route corresponding to the user trajectory data.
In this step, the historical planned route may specifically be a planned route already provided for the user, and the user trajectory data corresponding to the historical planned route may specifically be user trajectory data of the user when the historical planned route is provided for the user. Since the historically planned route includes unavailable road segments, and the user trajectory corresponding to the historically planned route is different from the user trajectory corresponding to the historically planned route that does not include unavailable road segments, the particular route may be determined from the user trajectory data and the historically planned route corresponding to the trajectory data. Specifically, when the historically planned route includes unavailable road segments, there may be a certain difference between the user trajectory and the historically planned route. For example, the user first travels along the historically planned route, deviating from the historically planned route during travel. When unavailable road segments are not included in the historically planned route, the user trajectory may be consistent with the historically planned route.
Optionally, step 205 may specifically include: determining a yaw position on a historical planning route corresponding to the track data according to the user track data, wherein the first position is the yaw position; the position after the yaw position on the historical planned route is the second position, and the route from the first position to the second position on the historical planned route is the specific route. For example, as shown in FIG. 3, assuming that the historically planned route from the starting location A to the ending location B provided to the user is A- > a1- > a2- > B and the user trajectory is A- > a1- > a3- > a4- > a2- > B, the first location may be a yaw location a1 and the second location may be a location between a1 and B in the historically planned route, such as a 5.
Further optionally, the position on the historically planned route a preset distance after the yaw position is the second position. Specifically, the distance between a1 and a5 in fig. 3 may be a preset distance.
Or the preset number of intersections after the yaw position on the historical planning route is the second position. Specifically, the number of intersections between a1 and a5 in fig. 3 may be a preset number.
It should be noted that there is no restriction on the order between step 205 and step 201.
According to the navigation method provided by the embodiment, all track routes from the first position to the second position are determined according to the user track data, whether the planned specific routes from the first position to the second position are included in all the tracks or not is judged, whether the specific routes include road sections with track quantity smaller than or equal to the preset track quantity threshold or not is judged, and if all the tracks do not include the specific routes and the specific routes include road sections with track quantity smaller than or equal to the preset track quantity threshold, the specific routes are unavailable routes, so that the unavailable road sections are determined according to the user track data.
