Pan-tilt, method for controlling pan-tilt, and photographing apparatus

Abstract

Embodiments of this application provide a pan-tilt, a method for controlling a pan-tilt, and a photographing apparatus. A magnetic-field generating apparatus for generating uniform detection magnetic field is mounted on a pan-tilt base of the pan-tilt, a conductor rod is mounted on a pan-tilt head of the pan-tilt, and two ends of the conductor rod are electrically connected to a voltage detection unit. In this way, in a process of the pan-tilt head rotating relative to the pan-tilt base, the conductor rod cuts magnetic induction lines of the detection magnetic field and generates an induced electromotive force. In addition, in the embodiments of this application, the induced electromotive force on the two ends of the conductor rod can be detected through the voltage detection unit. It can be understood that the induced electromotive force is directly proportional to a rotation angular velocity of the conductor rod, that is, is directly proportional to a rotation angular velocity of the pan-tilt head, so that the rotation angular velocity of the pan-tilt head can be obtained, and a technical problem that an existing pan-tilt cannot measure a rotation speed is resolved, wherein the structure is simple and easy to implement, and is convenient to use.
