摘要: The invention relates to a fingerprint library updating technology in the technical field of information, particular crowdsourcing data-based wireless method, andmainly aims at solving problem incorrect positioning caused by large data calculation amount and incomplete screening prior art, simplifying process saving system overhead. method mainly comprises following steps of: acquiring data; establishing an active passive library; respectively carrying out on separating fingerprints which are close each other have approximate signal intensity so as improve correctness libraries. is used for data.
