Embodiment Construction

[0077] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0078] The IMU (Inertial Measurement Unit, Inertial Measurement Unit) of the gimbal often produces a certain drift error due to the influence of zero point offset, noise interference and other factors, resulting in the gimbal not always maintaining a horizontal state in the direction of the roll axis, causing the gimbal to be centered. The image captured by the camera of the camera will be tilted visually, which does not conform to the usage habits of the observer.

[0079] However, the cloud platform provided by the embodiments of the present invention can be applied to aerial photography scenes, that is, objects on the ground are photographed in the air, so the photographed images often include objects with obvious vertical or horizontal fea...

Abstract

The invention discloses a holder control method and device, a holder and mobile equipment, and belongs to the technical field of holders. The method comprises the steps of according to an image currently shot by a camera built on the holder, extracting at least one line segment in the image used for identifying the edge of an object; acquiring the inclination angle of the object according to the at least one line segment; acquiring the inclination angle of the holder according to the inclination angle of the object; and correcting the posture of the holder according to the inclination angle ofthe holder. According to the holder control method and device, holder and computer equipment provided by the invention, the inclined posture of the holder can be corrected, so that the inclined posture of the camera is corrected, and thus the inclination of the image shot by the camera is avoided, and the imaging quality is improved.

Description

technical field [0001] The invention relates to the field of cloud platform technology, in particular to a cloud platform control method, device, platform and mobile equipment. Background technique [0002] In mobile scenes such as aerial photography, high-speed follow-up shooting, and handheld shooting, in order to ensure the stability of the captured images, more and more mobile devices will be equipped with gimbals, which are used to fix the camera and move and / or control the gimbal Or attitude adjustment can keep the camera stable, so as to ensure that the images captured by the camera remain stable. [0003] Affected by factors such as zero point offset and geomagnetic interference, the gimbal itself will vibrate during operation, causing the camera to vibrate as well, affecting the imaging quality of the camera. In order to compensate for the shaking of the gimbal, the gimbal can obtain two adjacent frames of images currently captured by the camera, determine the corr...
