The invention discloses a holder rotation control method and device, and an unmanned aerial vehicle. The method comprises steps that image information captured by an image capturing device mounted ona holder is acquired, and the image information is identified to acquire the target detection information; the position of a target object on the desired layout picture is determined based on the target detection information, and the adjustment action information of the holder is determined according to the position of the target object at the desired layout picture, the present angle of view of the image capturing device and the image information; the holder is adjusted to rotate according to the adjustment action information. The method is advantaged in that the acquired images are analyzedin the air, the holder can be automatically driven to take action according to preset requirements to achieve following shooting of the target object, establishing remote communication is not necessary, and accuracy of following shooting is higher.
