In addition, for the emergence of a new point of interest, the user's search database has not come and updated in a timely manner. It is cumbersome to simply search for nearby points of interest through information such as the name and classification of the point of interest to locate the destination. It is not very accurate. If the destination is located by the street and house number at this time, the process will be relatively easy.
[0004] We are usually familiar with the house number. The house number, referred to as the door number, is the number of the building on the street. It is used to mark the precise location of the building and the address. Using the house number can quickly and accurately locate the road network. At present, lack of related methods

Abstract

The invention discloses a house number retrieval method for a navigation device. The house number retrieval method for the navigation device includes the following steps: setting retrieval areas to narrow down retrieval ranges, setting retrieved administrative regions according to a provided administrative region list, searching street data according to input querying keywords and the retrieval areas, searching street house numbers according to analyzed street identities (ID), obtaining detailed information of the house numbers by using list ID of the house numbers, setting destinations according to the house numbers, and setting the destinations of navigation by the information of the house numbers and then a house number retrieve procedure is completed. The house number retrieval method for the navigation device has the advantages that address information in points of interest can be effectively used to conduct query through query of the house numbers, and the query still can be conducted through street numbers and the house numbers when names of the searched points of interest do not exist in a retrieval database.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a house number retrieval method of a navigation device. Background technique [0002] With the rapid development of automobiles, the scope of people's activities has gradually expanded, and is no longer limited to their own daily life areas. Do not know the way, and the situation of not being able to find the destination also happens frequently. If you can use the appropriate search function in the navigation device at this time, it can easily help us locate the destination. [0003] At present, a variety of retrieval functions have been provided in traditional navigation, which can provide users with the names and classifications of POIs, and query nearby POIs. In these traditional retrieval functions, only the names of POIs are used. Classification and location information are used as query conditions, and address information is not used to query. In real life, if we searc...
