Embodiment Construction

[0030] see figure 1 , which is a flow chart of a method for displaying points of interest provided in an embodiment of the present invention, applied to a device with enhanced implementation mode enabled, the method includes:

[0031] Step 101, receiving a keyword input by a user.

[0032] The input keyword can be any word that the user is interested in. For example, the keyword can be a specific POI name, such as "Cuiwei Building", or it can be a keyword that represents a certain type of POI that the user is interested in, such as "hotel", "hotel", "parking lot", etc.

[0033] Step 102, searching for points of interest matching the keyword within a preset range around the user's current location.

[0034] In the embodiment of the present invention, the preset range can be drawn with the current location as the center and the preset length as the radius. The geographical area covered by the obtained circle is the preset range. For example, the radius can be set to 200 meters...

Abstract

The invention discloses a method and a device for showing interesting points, and aims at solving the problem that POI cannot be displayed in the scene in the prior art. The method comprises the steps of receiving keywords inputted by a user; searching the interesting points meeting the keywords within the preset range surrounding the current location of the user; calculating the azimuth angle of each interesting point and the distance to the current location of the user according to the latitude and longitude coordinates of each searched interesting point and the latitude and longitude coordinates of the current locations of the user; determining the row coordinates and rank coordinates of each interesting point within the preset full-view-field matrix according to the azimuth angle of each interesting point and the distance to the current location of the user; determining the row coordinates and rank coordinates of the scene area within the screen view-field range in the preset full-view-field matrix according to the screen view-field range; overlapping the interesting points of which the row coordinates and the rank coordinates are in the scene area to the scene in the scene area to display. According to the technical scheme, the method has the advantages that the POI can be displayed in the scene.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a method and device for displaying points of interest. Background technique [0002] At present, Points of Interest (POI) around the user can be displayed on the electronic map, but displaying POIs on the electronic map can only let the user know which POIs exist around him and the approximate geographical location of these POIs, and the user cannot Intuitively associate the surrounding POI with its current actual environment (ie real scene). If the user arrives at a certain block, what the user wants is to intuitively see which POIs are in the block in front of him, which buildings these POIs are located in, and the location of the POIs in the buildings, but the way of displaying POIs in the electronic map cannot Meet the above needs of users. [0003] Therefore, how to display POI in real scenes has become a technical problem that needs to be solved urgently. Contents of the ...
