Embodiment

The invention discloses a kind of for generate method, equipment and the computer program of map datum based on point-of-interest positional information.In description below, many details are set forth for illustrative purposes to the thorough understanding about embodiments of the invention is provided.But it will be recognized by those skilled in the art, can or utilize equivalence setting to put into practice embodiments of the invention in the situation that there is no these details.In addition, show well-known construction and device with the form of calcspar, to avoid unnecessarily fuzzy embodiments of the invention.

Fig. 1 is the diagram that can generate based on point-of-interest positional information the system of map datum according to an embodiment.For many reasons, obtain detailed road network for the most cities in emerging nation (particularly 2 lines and 3 line cities) and may have challenge.For instance, these cities do not have the structure of having planned conventionally, and may have various narrow opening road and street instead of primary highway.Usually be difficult to obtain official's entry of these roads.In addition the company that, has the automobile of having enabled specialized GPS can employ people in city, to drive to obtain road network information everywhere.Although this method has been guaranteed detailed road network, there is transitable road but boom town is not may be in many regions actual, want to arrange that each service of location-based service and/or navigation Service and company need to buy the data that this may be comparatively expensive.

In order to address this problem, the system of Fig. 1 has been introduced the ability that generates map datum based on point-of-interest positional information.For these companies, may be a kind of comparatively cheap option by the data that obtain geocoding by masses' outsourcing or other modes.Can utilize the POI database for different cities geocoding.Described POI database can obtain by the outer packet technology of the use masses, or can buy from traditional mapping company.If POI, not by geocoding, can carry out geocoding to described POI by different geocoding technology.In one embodiment, the POI database of geocoding can be the input for system 100.

In one or more embodiment, each POI data has metadata associated therewith, such as building name, street name, terrestrial reference reference, zone name, city, geographic coordinate etc.This metadata can be used to POI data to troop.For instance, belong to city " x ", there is identical street name " y " and all POI in certain distance " z " can be grouped in single cluster.Each cluster can be associated with a node.May have multiple nodes for given street name, and described node can be connected to each other.There are different street name but the node that is closely adjacent to each other also can be connected.Can determine the edge weights that represents the distance between any two nodes.Subsequently in this manner constructing graphic to represent approximate road network.

According to each embodiment, can the figure based on constructing for example implement navigation by the standard shortest path first of operation dijkstra's algorithm and so on above.Because each node comprises POI, therefore can provide the route that goes to this node that relates to applied POI.For instance, route is described and can is and " continues on M.G. road, to advance about 5KM until you arrive Barista Coffee; near Barista Coffee, turn right and enter S.V. road; remain on that on S.V. road, you will see St.Francis school on the right side at 2KM place; continue to advance on S.V. road; next you will see at 4KM place Mount Mary Church; left-hand rotation enters Simpoli road near Mount Mary Church, continue the 4KM that advances, your destination will be in Ganesh retail shop side ".

As shown in fig. 1, system 100 comprises having the internuncial subscriber's installation (UE) 101 that goes to navigation platform 103, social networking service 107, navigation Service 109 and POI database 111 via communication network 105.

According to each embodiment, can the information based on obtaining process POI data in POI database 111 by navigation platform 103.As previously discussed, system 100 can depend on abundant POI data and the landmark data in a large number with good quality and carries out road network structure.POI in emerging nation or terrestrial reference not only relate to the place of shopping center, historic monument, cinema, hospital, school and so on, but also relate to local retail shop, shop and street pedlar.For example there is the retail shop of several welcome this locality " mom-and-pop store " type in India, such as teahouse, grocery store, refuelling station, restaurant etc.Therefore there are a large amount of POI data in these countries.Can be by utilizing the outer packet technology of the masses to collect this data in mode efficiently and fast.

According to each embodiment, can be used to fill POI database 111 for the outer packet technology of any POI masses of the high quality P OI data collecting, verify and divide into groups a large amount of.Collect and there is the metadata (comprising geographic coordinate) of enriching associated therewith with social networking service 107 and/or the shared POI of navigation Service 109 by the user of any UE101.The U.S. Patent Application Publication No. 2011/0151898 that title is " Method and Apparatus for grouping Points of interest according to area names (for method and apparatus point-of-interest being divided into groups according to zone name) " is by utilizing the outer packet technology of the masses to collect and determine an example of the efficient way of POI data.Table 1-1 below illustrates and can be collected and be stored in the exemplary POI data of processing for navigation platform 103 in POI database 111 by social networking service 107 by navigation Service 109 or user.

Table 1-1, sample POI data

Other of Yellow Page or POI data can use other sources of POI data, such as may be originated.If but from the POI data in these sources not by geocoding, may need to carrying out geocoding by these POI that produced by other sources, to be stored in POI database 111 and can be used by navigation platform 103.

In one or more embodiment, system 100 can the POI data based on obtaining in POI database 111 be constructed approximate road network by navigation platform 103.Relate to available POI data are trooped from the described approximate road network of higher levels structure, thereby and connect POI data formation figure by each cluster.The figure of constructing represents described approximate road network.

According to an exemplary embodiment, described in troop and can be described as follows.Available POI data in given city may have inhomogeneous distribution.In city, may have the POI distribution in some block higher, these blocks will represent intensive residence area or commerce area or center, city.Distribution in some remote part in city may be comparatively sparse.In described cluster step, can divide into groups to the POI data point of any uneven distribution.The Fig. 4 discussing below shows the distribution of the POI data point on the different streets in given city.Described POI data (such as above in the POI data shown in table 1-1) have metadata associated therewith, such as building name, zone name, terrestrial reference, city, gps coordinate etc.All or part of in the middle of this information of navigation platform 103 use trooped or divides into groups each POI data point.For each POI, navigation platform 103 is searched in the distance that is in kKM and is had other POI of identical street name.This step can inquire about to implement by usable range in spatial database simply.Can for example provide to spatial database the inquiry of " finding the POI apart from the street name=X in K " and so on.Can reduce like this complexity that each POI and each other POI are compared.Described cluster can be stored in the spatial database of for example POI database 111 and so on, and can carry out Optimizing Queries performance by usage space index.

In one or more embodiment, in the time that available POI data point is trooped, navigation platform 103 considers to belong to all POI data points of town (for example city Y).Navigation platform 103 considers to have all POI data points of identical street name (for example street name " X ") subsequently, and is inserted in S set _ xy.If any specific POI does not have street name information, navigation platform 103 can for example be checked the terrestrial reference field of this POI that can obtain in table 1-1.Navigation platform 103 attempts determining the street name of described terrestrial reference subsequently.

In form, S_xy={p_1, p_2 ..., p_n} comprises n the POI with street name=X and city=Y.For i=, (1 arrives n), and navigation platform 103 is considered each POI (p_i) in S_xy.For each p_i, navigation platform 103 is considered every other POI p_j, and wherein i is different from j, and calculates apart from d (p_i, p_j).If d (p_i, p_j) is <k (wherein k is a parameter of system), p_i and p_j belong to identical cluster C_i.Navigation platform 103 is labeled as POI p_j to be trooped and it is removed from S_xy, and no longer considers it to troop.After all POI that considered in S set _ xy, navigation platform 103 generates the set C_xy={C_1 corresponding to the cluster of street X and city Y, C_2 ..., C_m}.The attribute of these clusters is that each cluster comprises and belongs to identical street and approximating physically POI.

According to an exemplary embodiment, graphical configuration can be described as follows.After creating cluster, navigation platform 103 is associated each cluster C_i with a node N_i.The centre of form of each cluster C_i represents the geographic coordinate of this node N_i.The Fig. 5 discussing below shows described cluster and forms and node associated steps.Each cluster (so each node) is for along given street, approximating physically POI divides into groups.For instance,

node

1,2,3,4,5,6,7 may be associated with the street of " Swami Vivekanand Road " by name, and

node

8,9,10 may be associated with " Mahatma Gandhi Road ".Following each node that connects of navigation platform 103.With V_xy={N_1, N_1 ... N_n} represents to belong to the node set of street X and city Y.With V={V_xy, V_zy ... V_ky} represents the set of all nodes that belong to the different streets in the Y of city.

Navigation platform 103 is not losing consideration set V_xy in general situation.For each the node N_i in V_xy, navigation platform 103 is considered every other node and is selected and the immediate node of node N_i (N_j) (that is to say compared with N_i and the distance of gathering all the other nodes in V_xy, the distance minimum between N_i and N_j).If there is edge (e_ij or e_ji) between node N_i and N_j, navigation platform 103 is ignored N_j, and selects the second approaching node N_k.Navigation platform repeats this operation, until it finds more approaching with node N_i and does not have the node N_p at edge therebetween.Navigation platform 103 connects this two nodes with directionless edge e_ip subsequently.It should be mentioned that edge e_ip is nondirectional, therefore e_ip and e_pi will refer to identical edge.Navigation platform 103 adds edge e_ip in set E_xy to subsequently.The weight of this edge e_ip equals the distance between node N_i and N_p.After this step finishes, produce a nondirectional weighted edge set E_xy, its representative is corresponding to the edge of street X and city Y.All nodes that this step guarantees to belong to street X all and be connected to each other (that is to say between any two nodes in set V_xy and have a paths).Navigation platform 103 repeats this identical code for other streets, and obtains a set E={E_xy, E_zy ..., E_ky}.

Correspondingly, for example node 1 is connected by edge e_12 with 2.These two nodes are closer to each other, and belong to identical street.Other nodes are connected in a comparable manner.Belong to the node in identical street by connection, navigation platform 103 can start to draw street map.Navigation platform 103 can also obtain the following information about every a street:

The starting point in ■ street and emphasis: for belonging to all nodes of gathering V_xy, any two the node N_i in the definite V_xy of navigation platform 103 and the shortest path between N_j.Navigation platform 103 is set to 1 by all edge weights temporarily, and length based on path finds shortest path.Can adopt the standard of for example Floyd-Warshall algorithm and so on all to central shortest path first here.For instance, based on exemplary nodes set 1,2,3,4,5,6,7 previously discussed, the path between node 1 and node 7 is 6, and the path between node 2 and 4 is 2.All each to central, navigation platform 103 is selected the path with maximum length.Navigation platform 103 is assigned as the starting and ending node in this path starting point and the terminal in street subsequently.

The length in ■ street: once navigation platform 103 finds starting point and the terminal in street, navigation platform 103 just can move the standard shortest path first of for example dijkstra's algorithm and so on, to obtain the length in this path.Navigation platform 103 can use original edge weight (it refers to the actual range between any two given nodes).The street length obtaining can be an approximate evaluation, and if POI has good covering on given street, can improve described approximate accuracy.

The direction in ■ street: by observing the starting point in street and the geographic coordinate of terminal, navigation platform 103 can determine that described street is north-south or East and West direction.As a rule, in latitude and longitude, be associated with direction.For instance, in the time advancing from south orientation north, latitude can increase progressively, and in the time advancing from east to west, longitude can increase progressively.In addition, navigation platform 103 can consider that negative latitude shows south orientation, negative longitude show west to.

Determine now street information, the point of crossing that navigation platform 103 is determined between cross-street.Wander back to set V={V_xy, V_zy ... V_ky} represents the set corresponding to the node in all streets in the Y of city.For any two given streets, i.e. street X and street Z, navigation platform 103 is considered the node from set V_xy and V_zy.Each node for set in V_xy, whether navigation platform 103 is determined in set V_zy has any node closer to each other, and each other in distance L, wherein L is a systematic parameter.If have any such node in distance L, show that described Liang Tiao street has very large probability intersected with each other.Suppose that the distance between parallel street is greater than cross-street, select L by discretion, navigation platform 103 is got rid of the possibility that connects parallel street.

Navigation platform 103 is associated the edge between two nodes subsequently.Consider to discuss and example shown in Figure 5 above, node 6 and 8 and node 7 and 8 be regarded as closer to each other.Therefore, navigation platform 103 adds respectively edge e_68 and e_78.These edges are added in edge aggregation E subsequently.These edges connect two cross-street, and create the path from a street to another a street.Even if street name changes to street A ' from street A, this method is still caught the point that street name changes, and connects Zhe Liangtiao street, and the path of adjacency is provided.Navigation platform 103 has produced the figure G=(V, E) that catches street information and connect Liang Tiao street in the situation that of its intersection now.Therefore, the approximate road network of this figure representative.Owing to having embedded POI information in this figure, therefore it can be used to implement the navigation based on terrestrial reference.

It should be mentioned that the accuracy that is included in the street information in this figure G depends on density, distribution, quality and the quantity of POI data.By using our method, the second best in quality POI data that are distributed in given city can produce road network more accurately densely.Although the road network of method construct by us may not be very accurately, this level of approximation may be enough to provide the navigation based on terrestrial reference.

As previously discussed, can determine each cluster is associated with a node.Each node that belongs to particular street can be compared with each other node that belongs to identical street.Can relatively calculate distance from this.By using the efficient inquiry for the spatial database of for example POI database 111 and so on, can reduce the complexity of this step.After each POI is processed to determine node, navigation platform can be stored in any treated data in POI database 111, for the query calls that for example " finds in distance B and there is no the node of the street name=X of previous marginal existence, according to distance-taxis " and so on.If do not find the node in distance B, can increase described distance.Therefore, this implementation makes computation complexity minimize to a certain extent.Can use similar inquiry to find along the node at intersections of streets crossing.Final figure can be stored in spatial database and/or POI database 111 efficiently, and can carry out Optimizing Queries performance by usage space index.

According to each embodiment, can implement to process as a setting move previously discussed and troop and graphical configuration processing on POI database.That is to say as the pre-treatment step for various location-based services and implement.Once construct described figure, navigation platform 103 just can be configured to move various location-based services, such as the navigation based on terrestrial reference.

According to each embodiment, system 100 can be used to the navigation based on terrestrial reference as follows.Once determine the figure that represents road network, navigation platform 103 just moves the shortest path first of for example dijkstra's algorithm and so on thereon, to determine the path between source and destination.Consider that user wherein inputs the situation of start address and destination-address.Navigation platform can be determined the geographic coordinate being associated with this address by any address geocoding technology.Navigation platform 103 can inquire about POI database 111 with find out which POI and described come source and destination approach.For instance, if these POI are marked as respectively p_s and p_d, navigation platform 103 is determined any cluster and the node that these POI are affiliated subsequently.In this embodiment, be N_s and N_d by these vertex ticks.These nodes become and carry out source and destination node corresponding to the shortest path first on figure G=(V, E).

Consider to discuss for

node

1,2,3,4,5,6,7,8,9 above and example as shown in Figure 5, the shortest path from node 2 to node 9 can obtainedly be { 2-3-4-5-6-8-9}.Owing to there being POI to be associated with each node along this path, therefore can be with reference to these POI along described route.For instance, the user that navigation platform 103 can be UE101 by navigation API113 provides instruction, such as " you are in side, EFG shop (POI being associated with node 2), on Swami Viviekanand road, directly walk southwards, after 5KM, you will see on right side XYZ shop (POI being associated with node 3), continue the 4KM that advances, you will see PQR shopping center (POI being associated with node 4), continue the 3KM that advances, you will see ABC school (POI being associated with node 5), continue the 2KM that advances, you will see LMN retail shop (POI being associated with node 6), near 1KM and turn left to enter Mahatma Gandhi Road DEF arenas retail shop (POI being associated with node 8) continues to advance, continue the 3KM that advances, your destination will be in HIJ retail shop (POI being associated with node 9) side ".

It should be mentioned that the distance providing is approximate evaluation in described route.If described POI has good covering on given street, can improve accuracy.The major advantage of this navigation form is, can provide the reference for multiple POI for user.Even if therefore this user cannot find specific POI or POI title change or move, still there are other POI to be guided through UE101 to seek the user of navigation information.

As an example, UE101, navigation platform 103, social networking service 107, navigation Service 109 and POI database 111 utilize known, new or still agreement under development communicate with one another and with other component communications of communication network 105.In the present context, agreement comprises the how mutual regular collection each other of the information based on sending by communication linkage of network node in definition communication network 105.The different operating layer of every agreement in each node is effective, from generating and receive various types of physical signallings to selecting for transmitting the link of these signals, to by the indicated information format of these signals, send or receive described information to identifying which software application operating in computer system.In open system interlink (OSI) reference model, describe for passing through each conceptive different protocol layer of network exchange information.
