Abstract

The invention relates to the field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle holder attitude adjusting method and system thereof. The unmanned aerial vehicle holder attitude adjusting method comprises the following steps that the real-time image is photographed by using the camera on the holder; image analysis is performed on the real-time image so as to obtain the horizon line information in the image; and filtering fusion is performed on the horizon line information and the horizontal line information obtained by inertial navigation of the unmanned aerial vehicle,and the attitude of the unmanned aerial vehicle holder attitude is adjusted according to the result of filtering fusion. The problems that the holder attitude is difficult to accurately maintain in the acceleration process of the unmanned aerial vehicle and the holder attitude has integral drift in the Z-axis direction can be solved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to the attitude adjustment technology of the unmanned aerial vehicle platform. Background technique [0002] With the development of drone technology, the application fields of drones are becoming more and more extensive. When the camera on the gimbal of the UAV is used to shoot the ground, the gimbal needs to be kept stable, so it is very important to obtain the attitude information of the mounted camera. If the posture is not accurate, it will affect the user's shooting experience. Specifically, the captured video is skewed, or the lens cannot be aimed at the target. [0003] At present, most of the attitude algorithms of the gimbal use the angular velocity data collected by the IMU and the acceleration to obtain the attitude. Some gimbals also use geomagnetic sensors to participate in data fusion to obtain more accurate attitude data. [0004] However, the fusion algor...
