Document Type and Number:
WIPO Patent Application WO/2018/191957
Kind Code:
A1
Abstract:
Provided in the present invention are a camera mount attitude estimation method, camera mount estimation device, and camera mount having the camera mount estimation device. The method comprises: S1, measuring an angular velocity of a camera mount, and acquiring measurement attitude data on the basis of the angular velocity; S2, measuring motion state data of a carrier of the camera mount, and computing, according to the motion state data, reference attitude data of the carrier, the carrier carrying the camera mount; and S3, correcting, by employing the reference attitude data, the measurement attitude data to obtain camera mount attitude data. The present invention effectively handles an influence of a motion state of the carrier on the attitude of the camera mount when estimating the attitude of the camera mount, thus providing a highly accurate attitude estimate of the camera mount, and enabling precision control of the attitude of the camera mount.
