Abstract

A signal map construction method, a signal map construction device, a signal map construction equipment and a readable storage medium are provided. The method comprises the following steps: acquiring an original Wi-Fi fingerprint (S101); clustering the original Wi-Fi fingerprints to obtain Wi-Fi fingerprint clusters (S102); obtaining a new Wi-Fi fingerprint by using the original Wi-Fi fingerprint in the Wi-Fi fingerprint cluster (S103); a Wi-Fi signal map is constructed using the new Wi-Fi fingerprint (S104). Due to clustering and new Wi-Fi fingerprint acquisition, the data volume of the constructed Wi-Fi signal map can be greatly reduced, data caching and calculation overhead are reduced, on the other hand, the difference of signal characteristics among Wi-Fi fingerprints can be enhanced, and the positioning precision can be improved.
