Method for generating position reference line and method and device for determining position of interest point

Abstract

The invention discloses a method for generating a position reference line and method and device for determining the position of an interest point. The method comprises the following steps: based on map data, obtaining a closed area located at a preset acquisition side of an acquisition road; obtaining a closed area capable of falling into the interest point as a target closed area; and generating a position reference line of the collection road based on the target closed area. The position reference line can be provided for the release of the interest point, so that the problem that the acquired coordinates of the interest point are inaccurate is solved.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method for generating a position reference line, a method and a device for determining the position of a point of interest. Background technique [0002] A point of interest (POI) in an electronic map may correspond to a house, a store, a mailbox, a bus stop, a tourist attraction, etc. in the real world. At present, map data producers collect POIs through crowdsourcing to obtain collection data used to generate POIs, and the collection data at least include: images recorded by cameras of collection equipment that record information such as POI names and addresses, and, The position information of the POI collected by the positioning module of the collection device. Among them, the location information of outdoor POIs is generally collected by the GPS receiver integrated in the collection equipment. However, because GPS signals are easily affected by environmental facto...

Problems solved by technology

Among them, the location information of outdoor POIs is generally collected by the GPS receiver integrated in the collection equipment. However, because GPS signals are easily affected by environmental factors, the latitude and longitude coordinates recorded in the GPS location information of POIs will drift. , lag and other phenomena, which will lead to deviations between the final POI map position coordinates and the actual position coordinates. How to eliminate the deviation so that the POI map position coordinates and actual position coordinates tend to be consistent is a problem that personnel in the field need to solve
