Embodiment

[0053] A point of interest cross-conditional fuzzy query system for navigation devices, including:

[0054] Fuzzy query system for fuzzy query of POI data;

[0055] Cross condition query system, used for multi-condition cross query on point of interest data;

[0056] The fuzzy query system and the cross-condition query system are installed on a navigation device.

[0057] When using the query system, at the beginning, the user can arbitrarily select Chinese pinyin initial letter query, keyword query or classification query for query, and obtain the query result. If the user can immediately find the result he wants, the query ends. Otherwise the user continues with the query. When re-querying, the user can still choose any of the above three query methods to query, and the system will query in the results of the previous query according to the query method selected by the user. Repeat this until the user can immediately find the desired result from the list. Let's take the...

Abstract

The invention provides an interest point cross-condition fuzzy query system used for a navigation device, which comprises a fuzzy query system used for subjecting interest point data to fuzzy query, and a cross-condition query system used for subjecting the interest point data to multi-condition cross query. The fuzzy query system and the cross-condition query system are mounted on the navigation device. The invention is characterized in that a user can acquire preliminary query results by means of fuzzy query or other conventional query modes; and then the user starts the process of selection by repeatedly setting query conditions in order to pick the precise results. The system is capable of overcoming the shortcomings of the traditional interest point query mode, and greatly improves the efficiency of navigation system interest point query.

Description

technical field [0001] The invention relates to an information query method, in particular to a new type of interest point query method for a navigation system, which can provide a flexible and convenient point of interest query function. Background technique [0002] The navigation system is an embedded device that runs on mobile phones, portable self-navigation systems (PNDs), handheld computers (PDAs), and vehicle-mounted AVN (AudioVisual Navigation, audio, video, and navigation trinity car navigation products) and other embedded devices. (GPS) satellite positioning, combined with electronic map data and point of interest data for real-time navigation software and hardware systems. [0003] Navigation systems generally have functions such as map display, real-time positioning, point-of-interest search, path calculation, and guidance broadcasting. Among them, point-of-interest search is a more important function, which is the basis for path calculation and guidance broadca...
