Abstract

The technical scheme of the invention proposes a UWB anchor point, a calibration system and method, and a storage medium, and the UWB anchor point calibration method comprises the steps: obtaining the level state of a pin of the UWB anchor point, and determining and outputting the position of the UWB anchor point according to the level state of the pin of the UWB anchor point and a preset corresponding relation between the level state of the pin of the UWB anchor point and the position of the UWB anchor point. According to the technical scheme, the UWB anchor point self-recognition position can be achieved through the pin state, the pin state of the UWB anchor point is utilized, multiple anchor points do not need to be developed, the material management and control cost is saved, the whole vehicle does not need to be offline and calibrated again, compared with the prior art, the whole vehicle wire harness is simplified, wire rods needed by the anchor points are saved, signals do not need to be introduced from a master control module or other modules for judgment, the circuit structure of the UWB anchor point is simplified, and the cost of the whole vehicle is reduced.

Description

technical field [0001] The present application relates to the technical field of UWB (Ultra Wide Band, ultra-wideband), and in particular to a UWB anchor point, a calibration system, method and storage medium. Background technique [0002] UWB positioning is currently a new application for passenger cars. UWB positioning technology can be used on vehicles to realize vehicle positioning more accurately. It can not only perceive the position of the vehicle, but also perceive the position of other surrounding devices. In the process of installing the UWB anchor point on the vehicle, in order to realize the self-identification position of the UWB anchor point, it is necessary to introduce signals from the main control module or other modules to make the UWB anchor point judge, which makes the UWB anchor point circuit too complicated and the cost of the whole vehicle wiring harness is relatively high. high. Contents of the invention [0003] The present application provides a ...
