Title:
MOVEMENT TRAJECTORY DETERMINATION METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/142633
Kind Code:
A1
Abstract:
A movement trajectory determination method, a device, and a system. The method comprises: acquiring inertial information and step distance measurement information of a foot of a target object (S110); determining step length information according to the inertial information and the step distance measurement information (S120); determining step direction information according to the inertial information, and determining movement direction information of the target object according to the step direction information (S130); and determining a movement position of the target object according to the movement direction information and the step length information, so as to determine a movement trajectory according to the movement position (S140). The present method can solve the problem in existing technology where significant cumulative drift errors are prone to occurring, which thereby interfere with position determination and bring about a negative effect; said method has beneficial effects of improving positioning accuracy and stability.
