Abstract

The embodiment of the invention provides an ultra-wideband positioning method, device, computing unit and system based on a single base station. The method comprises the following steps: acquiring a first distance and a first azimuth angle of a first label relative to a positioning base station measured by the positioning base station, a target fingerprint at the position of the first label measured by an IMU module, and motion information of the first label; performing trajectory prediction according to the motion information to obtain a first prediction position of the first label; if it is determined that the first tag is located in a non-line-of-sight area of the positioning base station according to the first distance and the first azimuth angle, determining a second predicted position corresponding to the target fingerprint according to a pre-established corresponding relationship between fingerprints and positions; and according to the first prediction position and the second prediction position, determining a fusion positioning position where the first label is located. Accurate positioning can be realized through a single base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an ultra-wideband positioning method, device, computing unit and system based on a single base station. Background technique [0002] The base station communicates with the tag through Ultra Wide Band (UWB), and determines the distance (Distance, D) between the tag and the base station and the relative orientation of the base station according to the signal sent through UWB and the signal returned by the tag through UWB Angle (Angle, A), when the location of the base station is known, the positioning position of the tag can be determined according to D and A. [0003] However, limited by the signals of obstacles existing in the scene, a base station can only accurately locate objects located in a part of the area, and the base station cannot accurately locate the tags located outside the part of the area. In this paper, the part of the area It is called the line-o...
