Title:
METHOD AND APPARATUS FOR DETERMINING MOTION PARAMETER, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/226375
Kind Code:
A1
Abstract:
A method and apparatus for determining a motion parameter, and a system. The method comprises: acquiring readings of n inertial measurement units (2, 3, 4); and calculating a motion parameter of each of the inertial measurement units (2, 3, 4) according to the readings of the inertial measurement units (2, 3, 4) and in combination with a constraint relationship of relative motion among the inertial measurement units (2, 3, 4). By means of the method, the attitude calculation of a plurality of inertial measurement units (2, 3, 4) having a constraint relationship improves the dynamic accuracy compared with the independent calculation of a spatial orientation of each of the inertial measurement units (2, 3, 4).
