Title:
DUAL-FILTER-BASED TRANSFER ALIGNMENT METHOD UNDER DYNAMIC DEFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/233290
Kind Code:
A1
Abstract:
A dual-filter-based transfer alignment method under dynamic deformation. A dynamic deformation angle generated under dynamic deformation and a coupling angle between dynamic deformation and body motion will reduce the accuracy of transfer alignment; and a transfer alignment filter is divided into two parts, the first part estimates a bending deformation angle and the coupling angle, and uses an attitude matching method, and the second part estimates a dynamic lever arm, and uses a "speed plus angular speed" matching method.
