Document Type and Number:
WIPO Patent Application WO/2016/086862
Kind Code:
A1
Abstract:
A POI data processing method and device comprises: extracting, from the stored street view data, at least one street view video frame related to location information of a POI to be processed, and extracting feature information of the POI to be processed (S101); separately calculating the similarity between each street view video frame and the POI to be processed (S102); determining the comprehensive similarity according to the similarity (S103); determining whether the comprehensive similarity is greater than or equal to the preset similarity threshold; if yes, determining that the POI to be processed is valid; if not, determining that the POI to be processed is invalid, and deleting the POI to be processed (S104).By calculating the comprehensive similarity between the street view video frame related to the location of the POI to be processed and the POI to be processed, whether the POI to be processed is valid can be accurately determined, and the POI to be processed is deleted when the POI to be processed is invalid, so as to avoid the problem of wrong guidance and presentation due to the fact that invalid POIs are presented to a user when the follow-up user retrieves POIs.
