Title:
METHOD FOR DETECTING MECHANICAL ANGLE, GIMBAL, AND MACHINE-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/095106
Kind Code:
A1
Abstract:
A method for detecting a mechanical angle, a gimbal, and a machine-readable storage medium. The detection method comprises: acquiring a value measured and encoded by a magnetic encoding sensor provided at a gimbal (201); acquiring an electrical angle measured by a Hall sensor provided at the gimbal (202); and determining, according to the encoded value and the electrical angle, a mechanical angle of a motor in the gimbal (203), such that a shaft of the gimbal is controlled to rotate according to the mechanical angle. The invention can improve efficiency and precision of acquiring a mechanical angle of a motor in a gimbal.
