Method and device for detecting the position of a point of interest

Abstract

The invention provides a method and a device for detecting positions of interest points. The method comprises the following steps: obtaining a corresponding interest point of any door address in a map; detecting whether the obtained interest point is arranged in a predetermined area on one side of a road of the door address; and determining that the position of the obtained interest point is wrong data if the obtained interest point is not in the predetermined area on one side of the road of the door address. By the method and the device, interest points with wrong positions can be effectively detected.

Description

technical field [0001] The present application relates to a method and device for detecting the position of a point of interest, and in particular to a technology for detecting the position of a point of interest by using a predetermined area of ​​a road where a gate is located. Background technique [0002] With the rapid development of the Internet, various LBS (Location Based Service, location-based service) products and electronic map client applications have brought great convenience to people's daily life, and an important indicator to measure these products and applications It is the accuracy rate of the spatial position of the point of interest. [0003] In order to ensure the accuracy of the location of the POI, the prior art detects the POI data in the background mainly through the following two methods: one is to use the "manual street sweeping" method to detect the location of the POI in the background database.

[0003] In order to ensure the accuracy of the location of the POI, the prior art detects the POI data in the background mainly through the following two methods: one is to use the "manual street sweeping" method to detect the location of the POI in the background database. Correction, that is to say, the data collectors carry GPS equipment to the area to be collected to collect data to detect the points of interest in the background database. However, this method requires a lot of manpower and material resources, not only the data update cycle is long, but also When the amount of data involved becomes larger and larger, the labor cost used will also become higher and higher; the other is to use the data of map vendors (that is, manufacturers qualified for geographic drawing) to detect the positions of points of interest in the background database , however, due to the limited coverage of map merchant data, there will still be a large number of points of interest that cannot be covered by map merchant data
