Description
Technical field
The present invention relates to a kind of electronic map keywords search method and device thereof that is used for satellite navigation.
Background technology
In the prior art, auto navigation is realized by Automobile automatic navigation and service centre's assisting navigation dual mode.The displacement that utilizes sensor or positioning equipment to calculate the relative initial position of automobile continuously in the Automobile automatic navigation method, and the cartographic information of packing in car in advance utilize map matching technology to realize independent navigation.Service centre's assisting navigation is the vehicle that travels to be navigated according to the traffic information of collecting by service centre.
Disclosed Chinese patent literature CN1417708 related to a kind of electronic map device that is used for automobile satellite navigation system on May 14th, 2003.With semiconductor Storage Media device as high-speed Storage Media, the data type of employing inary Data (binary data) is used as the saving format of electronic chart in Storage Media, adopt relevance database search engine technique, set up a kind of can be used to follow make the electronic map device that a cover meets the navigational system purposes, can transfer related data apace in use.
Disclosed Chinese patent literature CN1815142 related to a kind of automobile navigation method on August 9th, 2006, comprise that a human pilot to vehicle provides the process of navigation information, navigation information passes through image, acoustic expression by car-mounted terminal, receive user's demand information and issue navigation information automatically by service centre, the user can require service centre that the artificial speech service is provided in the process of moving at any time, help the user to carry out the selection of route in real time, realize accurate navigation service next to the shin.Service centre is provided with unified service number, service centre all switches to the current local service center of user with user's demand for services information automatically according to user's traveling-position, in advance each information point is all unified to preserve detailed navigation information and the general navigation information of letter in the GIS of the service centre database, the position that service centre travels according to the user, arrive each the user and send navigation information by some forward direction car-mounted terminal, the navigation information that each user receives all comprises current location information and following two information by point.
The weak point of above-mentioned existing navigator is that it does not have the function of cartographic information retrieval, and searching to the destination makes troubles.
The electronic chart geographical location information comprises a large amount of points, line and face data, and will look for various correlative data in this huge database, must have a kind of efficiently, data retrieval mode easily.
The retrieval of electronic chart relates generally to contents such as search domain title, building name, street name, road name, comprises the simplification word, and for example " Peking University " abbreviates " Beijing University " as, and " Patent Office of State Intellectual Property Office " abbreviates " Patent Office " as.Present retrieval mode mainly contains full-text search, fuzzy search, compound retrieval (also claiming conjunctive search).
Disclosed Chinese patent literature CN1504927 related to a kind of electronic chart carries out intelligent retrieval by literal method that is used on June 16th, 2004.The abbreviation or the abbreviation of our the frequent use of input everyday spoken english when its characteristics are exactly retrieval, the search engine of electronic chart can be identified as the fixedly term that matches with abbreviation or the abbreviation of importing automatically, perhaps utilizes the mode of similar logic determines computing to inquire about its content.Can discern the abbreviation or the abbreviation of some information of place names automatically, with the input service of complexity become more simple, satisfy the custom of people's everyday spoken english.
The weak point of above-mentioned existing cartographic information search method is, it can not satisfy the Search Requirement of consumer to various information on services, as relate to eating in the people life, wear, live, go, various aspects such as work, study and amusement and recreation, can not combine with satellite navigation or mobile satellite location equipment, when retrieving consumption service project, place, play navigation function, to satisfy user's various demands.
