Embodiment 1

[0043] The embodiment of the present invention assumes that the application scenario is that there are three different known locations, and it is necessary to determine a hotel so that the distance or time from the three different known locations to the hotel by different friends is approximately the same. At this time, the target POI is a hotel. like Figure 5 As shown, the implementation process of the first method of searching for points of interest is introduced in detail below, and the method includes the following steps:

[0044] 501. Acquire a set of candidate interest points. The set of candidate POIs includes a plurality of candidate hotels meeting three known location requirements. This step can be achieved by:

[0045]The first way: the searched candidate interest points within a predetermined distance range of each known location form a candidate interest point set. There are corresponding hotels around a known location, and the searched candidate hotels corres...

Embodiment 2

[0070] Embodiment 1 describes the first method and terminal for searching a point of interest, and the application scenario is the same as that of Embodiment 1. The implementation process of the second method of searching for points of interest is introduced in detail below, such as Figure 7 As shown, the method includes the following steps:

[0071] 701. First, the candidate location points searched in the specified area, in the area excluding the specified area, on the specified road section, or in the area excluding the specified road section form a set of candidate location points.

[0072] 702. Find a target location point from the set of candidate location points, and the positional relationship between the target location point and three known locations respectively satisfies a predetermined rule. The target location point is a reference location for searching for a target point of interest. The preset rules include but are not limited to:

[0073] Rule A: The diffe...

Abstract

The invention discloses a method for retrieving a point of interest and a terminal thereof, relates to the field of location-based services, and aims to solve the problem that the point of interest is not determined by a plurality of locations existing in the prior art. The method comprises the following the steps of: acquiring a collection of potential points of interest; and finding the target point of interest from the collection of potential points of interest, wherein the location relationships between the target point of interest and at least two known locations meet the preset rule 1. The method may also comprises the following steps of: finding a target location point, wherein the location relationships between the target location point and at least two known locations meet the preset rule; and searching the target point of interest in a preset distance range of the target location point. The method and the terminal are mainly applied in the field of location-based services.

Description

technical field [0001] The invention relates to the field of location services, in particular to a method and terminal for retrieving points of interest. Background technique [0002] Mobile location service is a location-related service provided to users with the support of the electronic map platform, and it can also be called location-based service or location service. The POI service provides information related to the user's location. For example, when a driver is passing through an unfamiliar area and needs to find a nearby gas station, the information he needs is displayed on the phone and the closest location available for selection is marked. Some services also provide addresses, phone numbers, e-mail addresses, descriptions of places (ie, gas stations, bike retailers, restaurants, etc.), and route-planning navigation to selected places. [0003] In the prior art, the mobile location service technology only searches for the location of a point of interest accordin...
