Abstract

The technical solution of this application proposes a UWB anchor point, calibration system, method and storage medium. The UWB anchor point calibration method includes: obtaining the level state of the pin of the UWB anchor point, and according to the level state of the pin of the UWB anchor point, As well as the preset corresponding relationship between the level state of the pin of the UWB anchor and the position of the UWB anchor, the position of the UWB anchor is determined and output. This technical solution can realize the self-identification position of the UWB anchor point through the pin state, and use the pin state of the UWB anchor point itself, without the need to develop multiple anchor points, save material control costs, and do not need to re-calibrate the vehicle off the assembly line. Compared with the existing technology , simplifies the wiring harness of the whole vehicle, saves the wire required for the anchor point, does not need to introduce signals from the main control or other modules for judgment, simplifies the circuit structure of the UWB anchor point, and reduces the cost of the entire vehicle.

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 ...
