In some embodiments, the processor 208 may control the first camera 31 and the second camera 32 to lock on a specific target or angle for shooting. For example, the image information of the specific target may be obtained by analyzing the image information obtained by the first camera 31 and the second camera 32, and the first camera 31 and the second camera 32 may be controlled to lock the specific target for shooting by comparing the image information of the specific target with the real-time image information obtained by the first camera 31 and the second camera 32.

When the first camera 31 and the second camera 32 lock a specific target or angle for shooting, if the drone 200 is in a moving state or shakes, the processor 208 may calculate the flight attitude information of the pan/tilt head 100 according to the state information of the pan/tilt head 100, and output one or more motor signals according to the flight attitude information.

Further, because the pan/tilt 100 is provided with two cameras, namely the first camera 31 and the second camera 32, the pan/tilt 100 can complete the task that can be completed by a plurality of pan/tilt units, thereby reducing the number of the required pan/tilt units and saving the cost.

For example, the image information of the specific target may be obtained by analyzing the image information obtained by the first camera 31 and the second camera 32, and the first camera 31 and the second camera 32 may be controlled to lock the specific target for shooting by comparing the image information of the specific target with the real-time image information obtained by the first camera 31 and the second camera 32.

S602: if the unmanned aerial vehicle is in a moving state or shakes, calculating the flight attitude information of the holder according to the state information of the holder, and outputting one or more motor signals according to the flight attitude information;

if the drone 200 is in a moving state or is jittering, the processor 208 may calculate the flight attitude information of the pan/tilt head 100 according to the state information of the pan/tilt head 100, and output one or more motor signals according to the flight attitude information.

S603: and adjusting the first camera and the second camera in real time according to the one or more motor signals, so that the first camera and the second camera always lock a specific target or angle for shooting.

In this embodiment, the first camera 31 and the second camera 32 of the unmanned aerial vehicle 200 are respectively disposed at two ends of the roll motor assembly 21 and face in opposite directions, so that the first camera 31 and the second camera 32 do not move or rotate relatively, and a time difference is not generated when the first camera 31 and the second camera 32 are controlled to shoot; and the visual angles of the first camera 31 and the second camera 32 are about 180 degrees and opposite in direction, the first camera 31 and the second camera 32 can jointly complete 360-degree panoramic shooting, 360-degree panoramic images can be obtained at the same time, and then 3-dimensional experience feeling in virtual reality can be met. Further, because the pan/tilt 100 is provided with two cameras, namely the first camera 31 and the second camera 32, the pan/tilt 100 can complete the task that can be completed by a plurality of pan/tilt units, thereby reducing the number of the required pan/tilt units and saving the cost.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
