Title:
ARTIFICIAL INTELLIGENCE-BASED POSITIONING DATA PROCESSING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232585
Kind Code:
A1
Abstract:
An artificial intelligence-based positioning data processing method, comprising: acquiring multiple pieces of positioning data indicating user travel and recorded by a user terminal (S11); preprocessing the positioning data to obtain processing data (S12); processing the processing data on a spatial layer by using a clustering algorithm DBSCAN and a K-nearest neighbor classification algorithm KNN to obtain candidate regions comprising multiple categories, wherein each candidate region comprises a plurality of candidate stay points belonging to the same category (S13); for each category of candidate regions, according to cluster identifiers of a plurality of positioning points corresponding to the candidate regions, subdividing the plurality of candidate stay points in a time layer to obtain a stay point set, wherein the stay point set comprises a final stay point of the user travel (S14); and uploading the stay point set to a blockchain (S15). The method may be applied to smart transportation scenarios so as to promote the construction of smart cities.
