Title:
GIMBAL DRIVING METHOD AND DEVICE, AND HANDHELD CAMERA
Document Type and Number:
WIPO Patent Application WO/2021/208259
Kind Code:
A1
Abstract:
Provided are a gimbal driving method and device, and a handheld camera. The method comprises: acquiring an actually measured vector from an image center point in an image frame to a target center point of a tracked target at a first moment, so that same is used as a first actually measured vector; acquiring an actually measured vector from the image center point in the image frame to the target center point of the tracked target at a second moment, so that same is used as a second actually measured vector; determining a predicted vector from the image center point in the image frame to the target center point at the second moment according to the first actually measured vector and the second actually measured vector; and determining a target amount of rotation of a gimbal according to the predicted vector and then driving the gimbal. When the predicted vector is determined, since the effect of the actually measured vector from the image center point in the image frame to the target center point at the first moment on the predicted vector is taken into consideration, the determined predicted vector is relatively smooth, and a relatively smooth amount of rotation of the gimbal can be determined according to the predicted vector, such that a platform is controlled to move smoothly, thereby preventing the gimbal from shaking along with shaking of the tracked target.
