Title:
GIMBAL SYSTEM CALIBRATION METHOD AND APPARATUS, AND GIMBAL SYSTEM AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/081843
Kind Code:
A1
Abstract:
A gimbal system calibration method and apparatus, and a gimbal system and a computer-readable medium. The gimbal system comprises a gimbal (1010), a rocker (1020) for controlling the gimbal, and a posture sensor (1030) for measuring posture information of the gimbal. The gimbal comprises a rotating shaft mechanism, and an electric motor for driving the rotating shaft mechanism to rotate. The gimbal system calibration method comprises: entering a calibration mode (S310); respectively calibrating a rocker, an electric motor and a posture sensor (S320); determining whether the rocker, the electric motor and the posture sensor are successfully calibrated (S330); if the rocker, the electric motor and the posture sensor are all successfully calibrated, determining that a gimbal system is successfully calibrated, and exiting the calibration mode (S340). By means of this method, the calibration of a rocker, an electric motor and a posture sensor of a gimbal system can be completed during each calibration, without a user needing to performing individual calibration on each item, thereby reducing multiple tedious calibration operations and improving the user experience.
