In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.

The embodiment of the invention is applied to navigation equipment, the navigation equipment has a navigation function, and the navigation equipment can comprise various types, such as a mobile terminal, vehicle-mounted equipment, an independent navigator and the like.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a positioning method according to the present invention is shown, which specifically includes the following steps:

102, obtaining a route solving request, and matching a navigation route from a road network according to the route solving request, wherein the navigation route comprises a plurality of positioning points, and two positioning points form a first subsection route of the navigation route.

In the embodiment of the present invention, the user may search for the navigation route to the destination address by using the navigation device, for example, the user may input the destination address and the start address in the navigation device (of course, the user may not input the start address, and directly use the current position as the start address), and then perform the route query operation. After receiving a route query operation of a user, a navigation device generates a corresponding route request according to the route query operation, wherein the route request can include route information, such as a starting address, a destination address and user demand information, such as low traffic jam probability and less time consumption; and the navigation equipment can further carry out route finding according to the route finding request, namely, a navigation route between the initial address and the destination address in the route finding request is matched from the road network according to a recommended matching strategy corresponding to the road network. The matched routes can include a plurality of routes, the navigation equipment can select one navigation route from the plurality of routes to recommend to the user, and the navigation equipment can specifically set the routes according to requirements, such as recommending the navigation route which consumes the most time, recommending the navigation route which has the shortest route, recommending the navigation route which is the least congested, and the like; of course, the navigation device may also display a plurality of navigation routes to the user, and recommend a navigation route selected by the user to the user. In an embodiment of the present invention, the road network refers to a road system formed by interconnecting and interlacing various roads into a mesh distribution, and is a network formed by a plurality of road segments, each road segment corresponds to two positioning points, the road network may include a plurality of segment routes, and each segment route may include at least one road segment. Therefore, the navigation route may also comprise a plurality of positioning points, and two adjacent positioning points may form a road segment, that is, the navigation route may comprise a plurality of road segments; any two positioning points (which may be adjacent positioning points or non-adjacent positioning points) in the navigation route may form a first segmented route of the navigation route, so that the first segmented route may include at least one route segment, and when the segmented route includes a plurality of route segments, each route segment may form a route. For example, the navigation route: A-B-C-D-E, the navigation route comprises positioning points: A. b, C, D, and E, road segments included: A-B, B-C, C-D and D-E; any two points of these 5 positioning points may constitute a first segment of the navigation route, such as a and C, constituting a first segment: A-B-C, the first segment route comprising road segments: A-B and B-C, as well as B and D, form a first segment route B-C-D, which includes road segments: B-C and C-D.

And 104, matching a second sectional route corresponding to the positioning point in the navigation route from the updated road section set.

In the embodiment of the present invention, newly added road segments within a preset time may be collected in advance, and then the collected road segments are added to an updated road segment set, where the newly added road segments are newly added with respect to road segments in a road network, so that the road segments in the updated road segment set do not coincide with the road segments in the road network. One or more road sections in the updated road section set can form a subsection route, and the subsection route in the updated road section set is a newly added subsection route relative to the subsection route in the road network; wherein, the preset time can be set according to requirements. In the embodiment of the invention, the road network is not updated, and any two positioning points in the navigation route matched with the road finding request based on the road network can be additionally provided with a new sectional route besides a first sectional route in the navigation route; therefore, after the navigation route is matched, the segmented route corresponding to the positioning point of the navigation route can be matched from the updated road section set, and then the searched segmented route is used as a second segmented route corresponding to the positioning point of the navigation route.

And 106, determining a target navigation route according to the second sectional route and the corresponding first sectional route.

After the second sectional route is obtained from the updated road section set, the corresponding first sectional route of the second sectional route in the navigation route can be determined according to the positioning point of the second sectional route; then, a sectional route can be selected from the second sectional route and the corresponding first sectional route, for example, a sectional route which consumes less time is selected, for example, a sectional route which has a short route is selected, for example, a sectional route which does not include a highway is selected, and the like; and then determining a target navigation route according to the selected sectional route and the navigation route.

It should be noted that the above steps 102-106 can be performed by the terminal device, or by the server, and can be set as required.

In an example of the present invention, as shown in fig. 2, a schematic navigation route diagram according to an embodiment of the present invention is shown, where a navigation route from a starting point a to an ending point E is matched from a road network: A-B-C-D-E, wherein the navigation route comprises positioning points: A. b, C, D, and E, road segments included: A-B, B-C, C-D and D-E; and a first segment route: A-B, A-B-C, A-B-C-D, A-B-C-D-E, B-C, B-C-D, B-C-D-E, C-D, C-D-E, D-E. If the positioning points B and D in the navigation route are found from the updated road section set, the corresponding second sectional route B-D is obtained, and the first sectional route corresponding to the second sectional route B-D is B-C-D; therefore, a sectional route is selected from the B-D and the B-C-D to determine the target navigation route. If B-D is selected, the target navigation route is A-B-D-E.

To sum up, after obtaining a route finding request, the embodiment of the present invention may first match a navigation route corresponding to the route finding request from a road network, then search a second segment route corresponding to a positioning point in the navigation route from an updated road segment set formed by newly added road segments within a preset time, and then determine a target navigation route according to the searched second segment route and the corresponding first segment route; furthermore, according to the road network and the updated road section set, the target navigation route corresponding to the road finding request can be determined, and because the road sections of the newly added road network are not added into the updated road section set but the road network, a push matching strategy is not required to be re-formulated, so that the efficiency of updating the road network is improved.

In an optional embodiment of the present invention, newly added road segments may be collected in advance, and the collected road segments may be added to the updated road segment set, without adding the newly added road segments to the road network, and further without re-formulating a recommended matching strategy based on the road network, so as to improve efficiency of updating the road network.

Referring to FIG. 3, a flowchart illustrating the steps of one embodiment of a method of the present invention for collecting road segments in an updated set of road segments is shown; the method specifically comprises the following steps:

and step 302, analyzing the positioning log of each user, and determining a newly-added road section corresponding to the driving of each user.

In the embodiment of the invention, the navigation equipment can send the positioning information of each positioning point in the driving road of the user to the server, and then the server can generate the positioning log corresponding to the user according to the positioning information uploaded by the user; for example, each piece of uploaded positioning information is used as one log in the positioning log. The positioning information may include various parameters, such as a positioning point, for example, global positioning system coordinates, the accuracy of the positioning point, the time corresponding to the positioning point, and the speed of the user at the positioning point. Then, the positioning log of the user can be analyzed, and a newly added road section is matched from the road sections correspondingly driven by the user, and the method specifically comprises the following substeps:

and a substep 22 of selecting each log in a set time length from the positioning logs of the user.

And a substep 24, calculating the vertical distance from the positioning point of each log to each road section in the road network, and determining the minimum vertical distance corresponding to the positioning point of each log.

Sub-step 26, the number of anchor points for which the minimum vertical distance exceeds a distance threshold is determined.

And a substep 28, if the number exceeds a number threshold, determining the section corresponding to the segmented route formed by the positioning points of the logs as a newly added section.

According to the embodiment of the invention, each log in the set duration can be selected from the positioning logs of the user according to the timestamp of each log, wherein each log can correspond to one positioning point, and the set duration can be set as required. Then, for each log, the vertical distance from the positioning point of the log to each road segment in the road network can be calculated, and then the minimum vertical distance corresponding to the positioning point of the log is searched from each vertical distance. When the minimum vertical distance from the positioning point to a certain road section is greater than the distance threshold, the positioning point is determined not to be the positioning point on the road section; therefore, the number that the minimum vertical distance corresponding to the positioning points of each log exceeds the distance threshold value in the set duration can be counted, so that whether the road section corresponding to the segmented route formed by the positioning points of each log is the road section in the road network or not can be judged according to the number; wherein, the distance threshold and the quantity threshold can be set according to requirements. If the quantity exceeds a quantity threshold value, determining the road section corresponding to the segmented route formed by the positioning points of the logs as a road section not belonging to the road network, namely a newly added road section; and if the quantity does not exceed the quantity threshold value, determining that the road section corresponding to the segmented route formed by the positioning points of the logs is the road section of the road network.

In an optional embodiment of the invention, when the accuracy corresponding to the positioning point is low, it is likely that the current road environment is poor, and when the user driving speed corresponding to the positioning point is low, it is likely that the current road surface environment is poor, such as road construction and the like; therefore, in order to ensure the accuracy and the feasibility of the collected newly-added road sections, the positioning points can be filtered, namely the precision and the user running speed corresponding to the positioning points of each log are determined, and the positioning points with the precision larger than the precision threshold value and the user running speed larger than the speed threshold value are selected from the positioning points of each log; and calculating the vertical distance from each selected positioning point to each road section in the road network.

And step 304, clustering the newly added road sections driven by the users correspondingly, and determining the frequency corresponding to each newly added road section.

And step 306, selecting a newly added road section with the frequency exceeding a frequency threshold value, and adding the newly added road section into the updated road section set.

The newly-added road sections correspondingly driven by different users may be the same, so that the frequency of each newly-added road section can be counted after the newly-added road section correspondingly driven by each user is determined according to the positioning log of each user; and then, the newly added road sections can be selected according to the frequency and added into the updated road section set. Optionally, a newly added road section with a frequency exceeding a frequency threshold value can be selected and added to the updated road section set; the accuracy of determining the newly added road section is improved; wherein, the frequency threshold value can be set according to requirements.

It should be noted that the embodiment of the present invention may periodically collect the newly added road segments, or may collect the newly added road segments in real time, and then add the newly added road segments to the updated road segment set; i.e. the updated set of road segments is continuously updated. In an optional embodiment of the present invention, the road segments in the updated set of road segments may be presented in a map, so that the user can view the newly added road segments in the map; specifically, the road sections can be rendered in the map according to the corresponding positioning points of the road sections in the updated road section set, wherein the road sections which are not rendered in the map in the updated road section set can be periodically rendered, newly added road sections can be rendered in real time, and the rendering method can be specifically set according to requirements.

In another embodiment of the present invention, the second segment route corresponding to the positioning point in the navigation route may be matched according to the positioning point in the navigation route and the positioning point in the updated road segment set, which is specifically as follows:

referring to fig. 4, a flowchart illustrating steps of an alternative embodiment of a navigation method of the present invention specifically includes the following steps:

step 402, obtaining a route request, and matching a navigation route from a road network according to the route request.

In the embodiment of the invention, after a user executes a route query operation, navigation equipment can generate a corresponding route request according to the route query operation, and then obtain an initial address, a destination address and user requirement information from the route request; and then, a navigation route with the starting address as a starting point and the destination address as an end point is matched based on the road network, and the navigation route recommended to the user is determined. Wherein, between some two positioning points in the navigation route, except for the first subsection route in the navigation route, a newly added subsection route is possible; therefore, after the navigation route is matched, the second sectional route corresponding to the positioning point in the navigation route can be matched according to the positioning point in the navigation route and the positioning point in the updated road section set, which is specifically as follows:

and step 404, respectively matching the positioning point pairs in the navigation route with the positioning points in the updated road section set, and determining a second sectional route corresponding to the positioning point pairs in the updated road section set.

substep 416, searching a segmented route with the positioning point pair as an end point from the updated road section set when the positioning point pair exists in the updated road section set;

the substep 418 is to use the segment route with the location point pair as the end point in the updated road segment set as the second segment route corresponding to the location point pair.

The embodiment of the invention can firstly combine the positioning points in the navigation route in pairs to generate the positioning point pairs of the navigation route, such as: the navigation route comprises positioning points: A. b, C, D and E, any two positioning points of the five positioning points are combined to obtain the positioning point pairs (A, B), (A, C), (A, D), (A, E), (B, C), (B, D), (B, E), (C, D), (C, E) and (D, E) of the navigation route. Then, for each location point pair in the navigation route, the location point pair may be matched with a location point in the updated road segment set, whether the location point pair exists in the updated road segment set is searched, and if it is determined that the location point pair exists in the set, a segment route with the location point pair as an end point may be searched from the updated road segment set, where the segment route with the location point pair as an end point may include at least one road segment.

If the positioning point pair does not exist in the set, determining that the positioning point pair does not have a newly added segmented route, and searching a second segmented route corresponding to a next positioning point pair in the navigation route.

For example, referring to fig. 2, taking the anchor point pair (B, D) as an example, if the updated road segment set includes anchor points: B. d, F, G and H, if the links formed by the positioning points in the updated link set are: B-D, B-G, G-D, F-G, G-H, the corresponding included segmentation route is: B-D, B-G, G-D, F-G, G-H, B-G-D, F-G-H, B-G-H, B-G-F, F-G-D and H-G-D, and searching corresponding segmented routes B-G-D and B-D from the updated road section set by taking the B and the D as end points; the segmented routes B-G-D and B-D can be used as second segmented routes corresponding to positioning points in the navigation route, wherein the second segmented route B-G-D comprises two road segments: B-G and G-D.

In the embodiment of the present invention, another matching search method may include the following sub-steps:

substep 422, matching the positioning points in the navigation route with the positioning points in the updated road section set, and searching a segmented route containing the positioning points in the navigation route from the updated road section set;

substep 424, when determining that other positioning points exist in the navigation route in the segmented route containing the positioning points in the navigation route, selecting the segmented route taking the positioning points and other positioning points in the navigation route as end points from the segmented route containing the positioning points in the navigation route;

and a substep 426, taking the selected sectional route as a second sectional route corresponding to a positioning point pair formed by the positioning point and other positioning points in the navigation route.

In the implementation of the invention, a single positioning point of the navigation route can be directly adopted for searching, and the positioning points of the navigation route do not need to be combined into positioning point pairs in advance for searching; specifically, for each positioning point of the navigation route, the positioning point may be matched with a positioning point in the updated road segment set, and a segmented route including the positioning point is searched from the updated road segment set; if the segmented route containing the positioning point is found, whether other positioning points of the navigation route exist in the segmented route containing the positioning point can be judged; if the segmented route containing the positioning point comprises other positioning points of the navigation route, selecting a segmented route taking the positioning point and other corresponding positioning points as end points from the segmented route containing the positioning point; and then, taking the selected sectional route as a second sectional route corresponding to a positioning point pair consisting of the positioning point and other positioning points in the navigation route. And if the segmented route containing the positioning point is not found, or the segmented route containing the positioning point does not contain other positioning points of the navigation route, determining that no newly added segmented route exists between the positioning point and other positioning points.

In the embodiment of the present invention, the road segments in the updated road segment set may be unidirectional, such as only one-way road segments, so that when the positioning points in the navigation route and the positioning points in the updated road segment set are updated, the directions of the positioning points in the navigation route and the directions of the positioning points in the updated road segment set can be considered. For the first matching search mode, after the location point pairs of the navigation route are generated, the direction of each location point pair can be determined; when the positioning point pairs exist in the updated road section set, searching a segmented route taking the positioning point pairs as end points from the updated road section set, and then judging whether the direction of the segmented route is the same as the direction of the positioning point pairs; and if the two sectional routes are the same, determining the sectional route as a second sectional route corresponding to the positioning point pair. For the second matching search mode, after searching the segment route including the positioning point in the navigation route from the updated road segment set, other positioning points behind the positioning point in the navigation route direction can be determined, and after determining that other positioning points behind the positioning point in the navigation route direction exist in the segment route including the positioning point in the navigation route, the segment route using the positioning point and other positioning points behind the positioning point as end points can be selected; and then judging whether the direction of the sectional route is the same as the direction of the positioning point and other positioning points behind the positioning point in the navigation route, if so, selecting the sectional route taking the positioning point and other positioning points behind the positioning point as end points as a second sectional route corresponding to the positioning point pair formed by the positioning point and other positioning points.

After determining a second sectional route corresponding to the positioning point in the navigation route, a target navigation route can be determined according to the second sectional route and a first sectional route corresponding to the second sectional route, which is specifically as follows:

step 406, determining a first segment route having the same end point as the second segment route.

According to the embodiment of the invention, the first subsection route corresponding to the second subsection route can be determined, namely two end points of the second subsection route can be determined, and then the first subsection route with the same end point as the second subsection route is searched from the first subsection route of the navigation route according to the end points of the second subsection route. For example: navigation route: A-B-C-D-E, comprising the following road sections: A-B, B-C, C-D and D-E; and a first segment route: A-B, A-B-C, A-B-C-D, A-B-C-D-E, B-C, B-C-D, B-C-DE, C-D, C-D-E, D-E; if the corresponding second sectional route found from the updated road section set is B-D, determining that the end points of the second sectional route are B and D, and finding the first sectional route with the end points of B and D from the navigation route by taking B and D as the end points: B-C-D, which comprises two sections B-C and C-D.

The length of a link of a certain road and the actual passing time may not be in proportion, for example, a road with the length of 1km is 5 minutes, and a road with the length of 2km is 4 minutes; therefore, when calculating the transit time information of the sectional route, the theoretical transit time length of the sectional route is considered, and the link length of the sectional route can be considered. When the passing time information is calculated, the quotient of the road section length and the set speed can be calculated, then the sum of the quotient and the passing time is calculated, the sum is the second sectional route, and the calculation can be carried out according to the following formula:

VT＝len/v+time

wherein, VT is the traffic time information, len is the road section length, time is the time of passing through, v is the speed of settlement, can set up as required such as 60 km/h.
