Title:
CAMERA MOUNT CONTROL METHOD, AND CAMERA MOUNT
Document Type and Number:
WIPO Patent Application WO/2018/191964
Kind Code:
A1
Abstract:
A camera mount control method, and camera mount. The control method comprises: determining first attitude information of a camera mount; determining rotating angles of drive motors for one or more axes of the camera mount; determining, according to the first attitude information and the rotating angles, attitude error information of an attitude sensor; and correcting, according to the attitude error information, the first attitude information to obtain current attitude information of the camera mount. A camera mount (400) comprises: an attitude sensor (401) configured to determine first attitude information of the camera mount (400); an angle sensor (402) configured to determine rotating angles of drive motors for one or more axes of the camera mount (400); a processor (403) configured to determine, according to the first attitude information and the rotating angles, attitude error information of the attitude sensor (401). The first attitude information is corrected according to the attitude error information to obtain current attitude information of the camera mount (400). The camera mount control method and camera mount can effectively prevent the drifting problem in the prior art in which an accelerometer is employed to correct attitude information obtained by a gyroscope, such that the corrected camera mount attitude information can remain stable for a long period of time, and an image capturing apparatus mounted on the camera mount can capture a scene at a fixed position for a long perio of time without suffering from a drifting image capturing angle.
