Abstract

An embodiment in the invention relates to a method and apparatus for determining the location of a POI. According to the method, a video acquired on the way by using an acquisition tool and a track correspondingly recorded in the process of acquisition are stored in advance. The method comprises the following steps: determining a video frame with the POI in the video; determining a track point, corresponding to the video frame, in the track according to the shooting time of the video frame and the recording time of the track corresponding to the video; determining the heading direction of the acquisition tool at the track point according to the locations of the track point and adjacent track points; determining a shooting direction corresponding to the track point according to the heading direction of the acquisition tool at the track point and the value of an included angle between a preset shooting direction and heading direction of the acquisition tool; and determining the location of the POI in the video frame according to the location of the track point and the shooting direction. Thus, automatic determination of the location of the POI is realized in the embodiment, and operation efficiency and speed are improved.

Description

technical field [0001] The present application relates to the field of electronic maps, in particular to a method and device for determining the position of a point of interest. Background technique [0002] At present, the application of electronic maps is becoming more and more popular. How to better provide users with location-based services depends largely on the location information of POI (point of interest) in map data, such as providing users with POI information around its current location, etc. [0003] In order to update the location information of POI in time, the supplier directly dispatches workers to collect the location of POI on the spot; after the collection is completed, the collected location information of POI is fed back to the internal staff for processing to obtain the location of POI information. [0004] Since the field personnel need to collect the location information of a large number of POIs one by one, and after the collection is completed, t...
