Title:
GIMBAL, CONTROL METHOD FOR GIMBAL, AND PHOTOGRAPHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051568
Kind Code:
A1
Abstract:
Embodiments of the present application provide a gimbal, a control method for the gimbal, and a photographing device. A magnetic field generation device for generating a uniform detection magnetic field is mounted on a gimbal base of the gimbal, a conductor rod is mounted on a gimbal head of the gimbal, and the two ends of the conductor rod are electrically connected to voltage detection units. In this way, in the process that the gimble head rotates relative to the gimbal base, the conductor rod cuts a magnetic induction line of the detection magnetic field and generates induction electromotive force. Moreover, according to the embodiments of the present application, the induction electromotive force at the two ends of the conductor rod can be detected by means of the voltage detection units. It can be understood that the induction electromotive force and a rotation angular velocity of the conductor rod are in a positive proportional relationship, that is, the induction electromotive force and the rotation angular velocity of the gimbal head are in a positive proportional relationship, so that the rotation angular velocity of the gimbal head can be obtained, the technical problem that the rotation velocity of existing gimbals cannot be measured is solved, the structure is simple, implementation is easy, and use is convenient.
