Embodiment 1

[0028] see figure 1 , The method and device for generating video images provided by the embodiments of the present invention can be applied to an intelligent terminal 1 installed with an APP (application software), and the intelligent terminal 1 can be selected as a smart phone, a tablet computer, or the like. In order to obtain the real-time video stream of the unmanned aerial vehicle, the intelligent terminal 1 is connected to at least one of the unmanned aerial vehicle, the platform mounted on the drone, and the camera equipment mounted on the platform. In a specific implementation, see figure 2 , the drone communicates with the smart terminal 1 . Specifically, the image captured by the camera device including the target object can be transmitted back to the smart terminal 1 through a wireless link.

[0029] see also figure 1 , the video frame generation method may include the following steps:

Embodiment 2

[0078] Corresponding to the video shooting method of Embodiment 1, see Figure 4 , the embodiment of the present invention provides a device for generating a video image, which is applied to a smart terminal 1 installed with an APP. In this embodiment, the video image generation device may include a processor 11, and the processor 11 is configured to execute the steps of the shooting control method described in the first embodiment above.

[0079] In this embodiment, the processor 11 is used to communicate with the control device 2 on the side of the drone, wherein the control device 2 on the side of the drone can be realized by a dedicated control device, or can be implemented by a drone It can also be realized by a PTZ controller, so that the processor 11 can send a start command to the control device 2 on the side of the UAV to instruct the aerial photography of the UAV, and can receive it through the processor 11 The picture taken by the drone or other data information of...

Embodiment 3

[0082] Corresponding to the video shooting method of Embodiment 1, see Figure 5 , the embodiment of the present invention provides a device for generating a video image, which is applied to a smart terminal 1 . In this embodiment, the device for generating video images may include a receiving module 10 and a processing module 20 .

[0083] In the embodiment of the present invention, the receiving module 10 is configured to receive the returned video stream transmitted when the UAV flies in a specified flight mode.

[0084] The processing module 20 is configured to process the returned video stream to generate a video frame of a first preset duration, wherein the first preset duration is shorter than the duration of the returned video stream.

[0085] Optionally, the processing module 20 processes the returned video stream, and the step of generating a video frame of a first preset duration is performed after it is determined that the UAV satisfies a specified condition.

Abstract

The present invention provides a video picture generating method and apparatus, wherein the method includes the steps of: receiving a backhaul video stream transmitted by an unmanned aerial vehicle while flying in accordance with a specified flight mode; processing the backhaul video stream to generate a first preset-duration video frame, wherein the first preset duration is less than the durationof the backhaul video stream. The backhaul video stream obtained by the unmanned aerial vehicle is processed in the specified mode to convert the large backhaul video stream into a small video that is easy to share, and the user can quickly share in the social media such as the circle of friends so as to increase the fun of aerial photography of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of video data processing, in particular to a method and device for generating video images. Background technique [0002] In the field of drones, the return video stream transmitted during the flight of the drone is generally for users to watch directly, because the video transmitted to the ground equipment (such as smart phones, tablet computers, etc.) The stream is generally large, and it is difficult for users to directly share the returned video transmitted by the drone on social networks such as Moments. At present, most of them require users to manually cut the return video stream transmitted by the drone, so as to obtain small videos that are easy to share. However, the way users manually cut and obtain small videos may not be professional enough, and the special effects of small videos obtained are poor. Contents of the invention [0003] The invention provides a method and device for generating a video pic...
