Title:
INERTIAL MEASUREMENT-INTEGRATED MAGNETIC CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/221283
Kind Code:
A1
Abstract:
Disclosed is an inertial measurement-integrated magnetic control system (1), comprising an instrument (10), an electromagnetic device (20), and a processing apparatus (30). The instrument (10) comprises an inertial sensor and an induction coil (13) for generating an induction signal on the basis of a variable magnetic field. The electromagnetic device (20) comprises an electromagnetic coil (22) for generates a variable magnetic field on the basis of a variable current. The induction coil (13) receives the variable magnetic field generated by the electromagnetic coil (22) and generates the induction signal. The processing apparatus (30) acquires the motion state of the instrument (10) and the relative coordinates of the instrument (10) and the electromagnetic device (20) on the basis of an inertial signal measured by the inertial sensor and the induction signal generated by the induction coil (13). The magnetic control system (1) can improve the accuracy of positioning the instrument (10).
