This method is limited by the unification of the data specifications of each source, and this method itself has defects. First, the credibility of each source is different, but when the two data are inconsistent, it does not necessarily mean that the credibility is low. The source of the error data is the wrong data; the second is that the complementary set of each source data is large, the overlapping interval is small, and the non-overlapping data cannot be verified by this method

Embodiment Construction
[0042] figure 1 It is a flowchart illustrating a method for verifying location information of a point of interest according to the first embodiment of the present invention.
[0043] The method for verifying the position information of the POI according to the first embodiment of the present invention is a method for verifying the position of the POI based on the neighbor relationship of the POI. The neighbor relationship refers to the positional relationship of similar spatial positions between interest points. Therefore, the position of the other party in the neighbor relationship and the direction relative to itself can be used to describe one's own position. For example, if the address of Poi A is 30 meters south of XX Industrial Park B in District XX, then AB has a neighbor relationship.
[0044] Therefore, if the address of the first POI contains the information of the second POI, the first POI has a neighbor relationship with the second POI, and if the second POI also ...

The invention provides a method and device for verifying position information of interest points. The method includes the steps that the first interest point with a neighbor description relation is selected from an address; the second interest point having the neighbor description relation with the first interest point is selected, and the position information of the second interest point is acquired; the position information of the first interest point is verified through the position information of the second interest point. Through the method for verifying the position information of the interest points, the data positions of the interest points which cannot be verified through a traditional method can be verified, and therefore the accuracy rate of space of the interest points is increased.
Description
technical field [0001] The present invention relates to the field of location-based services (LBS), and more specifically, to the spatial location verification of points of interest in the LBS field. Background technique [0002] Navigation plays an increasingly important role in our daily life, and navigation products are gradually developing in the direction of refinement, humanization, and personalization, which puts forward higher requirements for the accuracy of navigation data. [0003] The navigation data includes the electronic map data stored in the storage device of the navigator, and the electronic map data is displayed on the screen to form a map image, and the electronic map data also includes some interest point information. Point-of-interest information is an important part of electronic map data, and it is often frequently used or more important facility information in a certain area, such as residential areas, schools, hospitals, shopping malls, supermarkets...
