POI (Point of Interest) data processing method and device

Abstract

The embodiment of the invention discloses a POI data processing method and device. The method comprises the following steps: extracting at least one frame of streetscape video frame related to position information of to-be-processed POI from prestored streetscape video data, and extracting feature information of the to-be-processed POI; respectively computing the similarity of each streetscape video frame and the to-be-processed POI; determining a comprehensive similarity according to the similarity; judging whether the comprehensive similarity is greater than a preset similarity threshold value; if the comprehensive similarity is greater than the preset similarity threshold value, determining that the to-be-processed POI is valid; otherwise, determining that the to-be-processed POI is invalid, and deleting the to-be-processed POI. The scheme is capable of accurately judging whether the to-be-processed POI is valid through the computation of the comprehensive similarity of the streetscape related to the to-be-processed POI position and the to-be-processed POI, and deleting the to-be-processed POI when the to-be-processed POI is invalid, thereby avoiding the problem that the invalid POI is displayed to the user to cause false guidance and displaying when the subsequent user searches the POI.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a POI data processing method and device. Background technique [0002] The electronic map contains a large number of POIs (Points of Interest), such as shops, shopping malls, parking lots, hotels and so on. However, in real life, POIs often change, such as POI removal. At this time, the POI in the electronic map is actually invalid (that is, it does not exist), and the POI needs to be deleted from the electronic map. If the POI is not deleted, Subsequent users will still display invalid POIs to users when searching for POIs, which will bring wrong guidance and display to users. [0003] At present, it is mainly determined whether POIs in electronic maps are valid through on-site surveys by collectors and user feedback. However, there are tens of thousands of POIs in electronic maps. This method of determining whether POIs in electronic maps are valid is inefficient and time-consum...

[0003] At present, it is mainly determined whether POIs in electronic maps are valid through on-site surveys by collectors and user feedback. However, there are tens of thousands of POIs in electronic maps. This method of determining whether POIs in electronic maps are valid is inefficient and time-consuming. The extension is large, and it is impossible to accurately and quickly determine whether the POI in the electronic map is valid
