Abstract

A pan-tilt control method and apparatus, a storage medium and an unmanned aerial vehicle are provided. The method includes acquiring a current viewing angle of an image pickup device provided on a pan-tilt; determining an adjustment strategy for adjusting the pan-tilt according to the current viewing angle; and adjusting the pan-tilt according to the adjustment strategy so that the image pickup device can output a stable image. The pan-tilt control method, the apparatus and the storage medium effectively overcome problems influencing stable output of camera images in the prior art and being not conducive to the acquisition and monitoring of the data information, and also ensure accuracy of images collected by the image pickup device, thus improving practicality of the pan-tilt control method and facilitating promotion and application in the market.

Description

technical field [0001] The invention relates to the technical field of pan-tilt control, in particular to a pan-tilt control method, device, storage medium and unmanned aerial vehicle. Background technique [0002] The pan / tilt is a supporting device for installing and fixing the camera. The pan / tilt is generally divided into two types: fixed and electric. Among them, the fixed pan / tilt is suitable for the situation where the monitoring range is not large, and the electric pan / tilt is suitable for scanning and monitoring a large area. When the camera is moving, in order to ensure that the camera outputs a stable image, the motorized gimbal can receive signals from the controller to move precisely, so as to ensure that the camera can output a clear and stable image. [0003] In the prior art, the pan / tilt control system and the camera control system are two independent control systems, so that the pan / tilt and the camera need to be controlled separately. When the focal length...
