Embodiment 1

[0019] This embodiment provides a method for generating a house number information base, such as figure 1 shown, including the following steps:

[0020] Step 101. Receive a POI data file in order to obtain POI information; the POI information includes POI name, address, zip code, phone number, classification, coordinates, and the like. Described point of interest data file comprises the actual POI data that field collection obtains, promptly comprises the original file of basic information such as POI name, POI address, telephone, classification, coordinate, zip code, and file format generally has file formats such as dbf, csv, dbf is in binary format and csv is a comma-separated text file. Preferably, the present invention does not perform file format conversion, but directly recognizes the data files in the two formats according to the extension names of the files. For the convenience of management, the input data is named in units of cities.

[0021] Step 102, reducing r...

Embodiment 2

[0048] refer to figure 2 , this embodiment shows the device for generating the house number information base of the present invention, including:

[0049] The receiving unit 201 is used to receive the POI data file so as to obtain the POI information, the POI information includes the POI address and coordinates, and the POI address includes the house number; the parsing unit 202 is used to obtain POI information according to different data formats Call the dbf file content parser or the csv file content parser; the conversion unit 203 is used to convert the full-width number in the point-of-interest information obtained by the receiving unit 201 into a half-width number, which is convenient for subsequent processing and unified storage standards; the acquisition unit 204 , for calculating the pending house number information according to the house number information in the POI information; the zip code processing unit 205 is used to extract the corresponding relationship betw...

Abstract

The embodiment of the invention provides a method and a device for generating a doorplate information library to solve the problem of address matching failure due to absence of doorplate information. The method for generating the doorplate information library comprises the following steps of: acquiring interest point information, wherein the interest point information comprises an interest point address and an interest point coordinate, and the interest point address comprises a house number; acquiring doorplate information to be determined according to the interest point information, wherein the doorplate information to be determined comprises the house number and a coordinate corresponding to the house number; and generating the doorplate information library according to the interest point information and the doorplate information to be determined. The embodiment of the invention also provides a device for generating a doorplate information library. According to the method and the device, the complete doorplate information library can be generated, so the address matching can be successively carried out.

Description

technical field [0001] The invention relates to a navigation technology, in particular to a method and device for generating house number information database. Background technique [0002] In the field of location-based service (Location Based Service, LBS), point of interest (POI) refers to the place that the user wants to know or is about to arrive at, and is one of the important components of electronic map data. In applications such as maps and wireless location services, people can search for POIs they are interested in on electronic maps, and with the help of software, they can query relevant information about POIs or guide them to their destinations. [0003] In the prior art, the data collection of the electronic map is mainly through manual methods to collect information such as longitude and latitude coordinates of points of interest and roads on the spot, and then make these collected coordinate points into a map. This method has many disadvantages, one of which...
