Abstract

The embodiment of the invention discloses a method, a device, an apparatus and a medium for determining the position of a point of interest, and relates to the field of electronic maps. The method comprises the following steps: acquiring at least two original images obtained by collecting the target scene belonging to the target point of interest, and acquiring position information of each original image; According to the scene characteristics of each original image, the acquisition position relationship of each original image is determined. According to the acquisition position relation of the original image, correcting the acquisition position information of the original image; According to the corrected acquisition position information, the position information of the target point of interest is determined. The embodiment of the invention provides a method, a device, an apparatus and a medium for determining the position of a point of interest, thereby realizing automatic and accurate determination of the position of the point of interest.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic maps, and in particular to a method, device, device and medium for determining the position of a point of interest. Background technique [0002] Currently, developers display POIs on electronic maps based on their actual locations. The user can view the actual location of the point of interest through the electronic map. [0003] The method for determining the actual location of the point of interest in the prior art includes: the merchant uploads the location of the point of interest by itself, or manually collects the actual location of the point of interest based on the GPS (Global Positioning System, Global Positioning System). [0004] In the process of realizing the present invention, the inventor found that due to the error of the GPS itself, and the collector submits the current location as the location of the point of interest before arriving at the designated locatio...
