Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides a method for positioning an address. Referring to fig. 1, a flow chart of a method for address location according to an embodiment of the invention is shown. The method may be performed by an apparatus, which may be implemented in software and/or hardware.
In this embodiment, the method for address location includes:
step S10, obtaining address information of a target client, and searching positioning points of the address information on a map based on a preset map engine.
Step S20, if a plurality of locating points are found, the position coordinates of the locating points are obtained, and the position coordinates of the mass centers of the locating points are calculated according to the obtained position coordinates.
The preset map engine used in the embodiment of the invention can be the existing map engines such as a hundred-degree map, a high-German map and the like. Any one of which can be selected for searching; or searching by using a plurality of map engines at the same time, positioning by combining the search results of the map engines, and displaying the search results of the map on the same map display interface when searching by using the map engines.
When locating the address of a client, the client information of the client is called from a database, the address information of the client is obtained, the client is searched on a preset map engine according to the address information, locating points are obtained and displayed, and if a plurality of locating points exist in the search result, the current locating result is not an accurate locating result. After searching the address of the client, three ground points are displayed on the map, at the moment, the position coordinates of the three positioning points are obtained, the mass centers of the three position coordinates are calculated, and the position coordinates of the positioning points where the mass centers are located are obtained. It will be appreciated that when there are only two anchor points, the centroid is at the midpoint of the line connecting the two anchor points. And judging whether the address information is accurately positioned on the map according to the position coordinates of the positioning points and the mass centers.
And step S30, judging whether the positioning of the address information on the map is accurate or not according to the position coordinates of the positioning points and the position coordinates of the mass center.
And step S40, if the positioning is accurate, updating the centroid to be a new positioning point of the address information.
Specifically, the manner of judging whether the positioning is accurate according to the mass center is as follows: and calculating the distance between each positioning point and the mass center according to the position coordinates of the positioning point and the position coordinates of the mass center.
And judging whether the positioning of the address information on the map is accurate or not according to the calculated distance, wherein if the distances from the positioning points to the mass centers are smaller than a preset threshold value, the positioning of the address information on the map is judged to be accurate, otherwise, the positioning of the address information on the map is judged to be inaccurate.
The magnitude of the preset threshold value can be preset according to the requirements on positioning accuracy, the distribution density of the building and other factors. And calculating the distance between each locating point and the centroid, if the distances between each locating point and the centroid are smaller than a preset threshold value, determining that the degree of dispersion between the locating points is smaller, taking the centroid as the locating point corresponding to the address, and storing the position coordinates of the centroid and the address information in a correlated manner. The state of the address of the client may be marked as a calibrated state. And when the address information of the client is positioned on the map, firstly inquiring the state mark of the address of the client, judging whether the address is calibrated or not according to the state mark, if so, directly acquiring the position coordinate associated with the address mark, and displaying the corresponding positioning point on the map according to the position coordinate. If not, calibrating the address according to the steps.
Further, after step S30, the method further comprises the steps of:
if the positioning is inaccurate, determining a preset area to which the target client belongs, and acquiring a client list of the preset area from a database; inquiring the clients with the address information identical to the address information of the target client in a preset range and calibrated according to the client list; and updating the locating point of the address information of the client to be a new locating point of the address information of the target client.
If the distances from one or more locating points to the mass center in the locating points are larger than a preset threshold value, the fact that the degree of dispersion between the locating points is larger can be judged, the accuracy of the current locating result is judged to be lower, at the moment, the mass center is not used as the locating point, other clients with calibrated addresses, which are close to the address of the client, are searched from a client list, the address of a new client is migrated nearby by using locating information of the clients, namely, the locating point with the address closest to the address is selected from the clients with the similar addresses as the locating point of a target client.
In general, an address is expressed in terms of a hierarchical relationship of administrative areas. For example, a Shenzhen Futian region xx road xx number xx building, where in this address, the first level is a city level administrative region, the second level is a district level administrative region, "xx road" is the third level, it is a road section level, "xx number safe building" is the fourth level, it is a point of interest level, generally refers to a specific building, such as "xx building", "xx cell", and so on. In addition, the customer information generally includes more detailed address information after the fourth level, for example, the xx-way xx number xx cell xx-layer xx room of Shenzhen Futian district, in which, in the scheme, the same address in the preset range generally means that the information of the first four levels is the same, that is, only the information is needed to be located on the same specific building, and the more detailed address information under the fourth level may be different.
In this way, each time a new customer is added to the database, address targeting for that customer can be accomplished in both ways. Of course, it can be understood that if only one locating point exists on the map after searching according to the address information of the target client, the position coordinates of the locating point and the address information of the client are associated and stored.
Further, in another embodiment, after the step of querying, according to the client list, the clients whose address information is the same as that of the target client within a preset range and whose address information is calibrated, the method further includes the steps of:
if one inquired client exists, executing the step of taking the locating point of the address information of the client as the locating point of the address information of the target client; if a plurality of queried clients exist, displaying positioning points of address information of the clients on a map; when a selection instruction triggered based on the displayed positioning point is received, the positioning point corresponding to the selection instruction is updated to be a new positioning point of the address information.
Or in other embodiments, after the step of querying, according to the client list, the client whose address information is the same as that of the target client within a preset range and whose address information is calibrated, the method further includes:
if the client with the address information identical to the address information of the target client in the preset range and calibrated is not found, outputting prompt information based on a positioning point of the address information of the target client on a map so as to enable a user to manually calibrate the address information of the target client according to the prompt information; and receiving a locating point set by a user for the address information, and updating the locating point to be a new locating point of the address information.
The address locating method provided by the embodiment obtains the address information of the target client, and searches locating points of the address information on the map based on a preset map engine; if a plurality of locating points are found, acquiring the position coordinates of the locating points, and calculating the position coordinates of the centroids of the locating points according to the acquired position coordinates; judging whether the positioning of the address information on the map is accurate or not according to the position coordinates of the positioning points and the position coordinates of the mass center; if the positioning is accurate, the centroid is updated to be a new positioning point of the address information.

After searching the address of the client, three ground points are displayed on the map, at the moment, the position coordinates of the three positioning points are obtained, the mass centers of the three position coordinates are calculated, and the position coordinates of the positioning points where the mass centers are located are obtained. It will be appreciated that when there are only two anchor points, the centroid is at the midpoint of the line connecting the two anchor points. And judging whether the address information is accurately positioned on the map according to the position coordinates of the positioning points and the mass centers.
Specifically, the manner of judging whether the positioning is accurate according to the mass center is as follows: and calculating the distance between each positioning point and the mass center according to the position coordinates of the positioning point and the position coordinates of the mass center.
And judging whether the positioning of the address information on the map is accurate or not according to the calculated distance, wherein if the distances from the positioning points to the mass centers are smaller than a preset threshold value, the positioning of the address information on the map is judged to be accurate, otherwise, the positioning of the address information on the map is judged to be inaccurate.

And calculating the distance between each locating point and the centroid, if the distances between each locating point and the centroid are smaller than a preset threshold value, determining that the degree of dispersion between the locating points is smaller, taking the centroid as the locating point corresponding to the address, and storing the position coordinates of the centroid and the address information in a correlated manner. The state of the address of the client may be marked as a calibrated state. And when the address information of the client is positioned on the map, firstly inquiring the state mark of the address of the client, judging whether the address is calibrated or not according to the state mark, if so, directly acquiring the position coordinate associated with the address mark, and displaying the corresponding positioning point on the map according to the position coordinate.
