Abstract: This application relates to a UWB base station anomaly detection method. The method includes: obtaining a first distance that is between each of the N UWB base stations and the UWB tag and that is obtained through measurement; obtaining an estimated value of spatial coordinates of the UWB tag in the first coordinate system based on the first distance and spatial coordinates of each UWB base station in the first coordinate system; obtaining a second distance between each UWB base station and the UWB tag based on the estimated value and the spatial coordinates of each UWB base station in the first coordinate system; and determining, based on the first distance and the second distance that correspond to each UWB base station, whether a UWB base station in the N UWB base stations is abnormal.
