The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, an application scenario of the video editing method provided in the present application is shown. The unmanned aerial vehicle is provided with a shooting device, so that the unmanned aerial vehicle can shoot aerial pictures when flying and hovering.

The unmanned aerial vehicle can be an unmanned aerial vehicle, a traversing machine and the like, and the shooting device can be a camera, a camera and the like with an image acquisition function.
Referring to fig. 2, a video clipping method is shown for the present application according to one embodiment. The method may be performed by an electronic device in communication with the UAV. The electronic device communicates with an unmanned aerial vehicle equipped with a camera and can be used for processing video data. As shown in fig. 3 (a), the electronic device may be a remote controller equipped with a display screen, in which a processor or a processing chip is provided. The user can view the video data returned by the aircraft on the display screen, and the processor or processing chip in the remote controller can process the video data. The electronic device may also be a mobile terminal, such as a cell phone, tablet, ipad, etc. (not shown in fig. 3), which may run a virtual interface with remote control functionality. The mobile terminal can control the flight of the unmanned aerial vehicle through virtual controls (such as a virtual rocker, a virtual pulley and the like) in the virtual interface, and view and process video data returned by the unmanned aerial vehicle. In addition, as shown in fig. 3 (b), if the electronic device is a mobile terminal, the mobile terminal and the remote controller may be combined through an electrical connection (as shown) or a wireless connection (not shown), so that the user can control the flight of the unmanned aerial vehicle through the remote controller on one hand, and can view and process video data returned by the unmanned aerial vehicle at the mobile terminal on the other hand. The electronic devices of the present application include, but are not limited to, the above categories, and are not limited thereto. In an alternative embodiment, the steps shown in fig. 2 may also be performed by the unmanned aerial vehicle, and specifically, may be performed on the video captured by the capturing device through an image processing module on a processing chip provided in the unmanned aerial vehicle.
As shown in fig. 2, the method comprises the steps of:
step 110: and acquiring video data shot by the shooting device, flight attitude data of the unmanned aerial vehicle and timestamp data.
Step 120: clipping the video data based on the flight attitude data and the timestamp data.
In one embodiment, when the electronic device performs the above steps, after the electronic device is connected and communicated with the unmanned aerial vehicle, video data shot by a shooting device of the unmanned aerial vehicle, flight attitude data of the unmanned aerial vehicle, and timestamp data can be acquired by the electronic device, wherein the timestamp data is used for synchronizing the flight attitude data and the video data.
In addition, the electronic device may acquire the three data from the unmanned aerial vehicle in real time during the flight of the unmanned aerial vehicle and perform editing, and certainly, the electronic device may also store the video data shot by the shooting device in real time during the flight of the unmanned aerial vehicle, record and store the flight attitude data and the generated timestamp data of the unmanned aerial vehicle at the same time, and read the three data from the memory of the unmanned aerial vehicle to perform editing after the shooting of the unmanned aerial vehicle is completed. The clipped video data can be used for playback or sharing.
In one embodiment, when the above steps are performed by the unmanned aerial vehicle, timestamp data may be generated by the unmanned aerial vehicle in real time during flight based on the flight attitude data of the unmanned aerial vehicle, whereby video data captured by the capturing device is clipped in real time based on the flight attitude data and the timestamp data, and the clipped video is transmitted to the communicatively connected electronic device for playback or sharing. Certainly, the unmanned aerial vehicle may also store the video data shot by the shooting device in real time during the flight, record and store the flight attitude data and the generated timestamp data of the unmanned aerial vehicle, clip the video data after shooting is completed, and send the video obtained by clipping to the electronic device in communication connection for playback or sharing.
It should be noted that, in the clipping process, since the flight attitude data of the unmanned aerial vehicle at different times and the video data captured at the time can be synchronized by the timestamp data, when the video data captured by the unmanned aerial vehicle flying at a specific flight attitude is to be clipped, the electronic device can find out the timestamp data corresponding to the specific flight attitude data by searching, and clip out the video data according to the corresponding timestamp data.
The video clipping method provided by the embodiment synchronizes the video data with the flight attitude data of the aircraft by using the timestamp data, automatically clips the recorded video based on the flight attitude data and the timestamp data, can automatically clip the video data shot by the unmanned aircraft when the unmanned aircraft flies in a specific attitude, and retains the wonderful picture which the user wants to leave.
The following description is made in terms of the video clipping method performed by an electronic device in communication with an unmanned aerial vehicle, and it will be understood that the method is performed by an unmanned aerial vehicle on the same principle as the method performed by an electronic device, and the difference is only transmitted to the electronic device after the unmanned aerial vehicle has finished clipping, and therefore the following description is also applicable to the case where the method is performed by an unmanned aerial vehicle.
In an alternative embodiment, the electronic device executes step 110 to acquire video data captured by the capturing device, flight attitude data of the unmanned aerial vehicle, and time stamp data from the unmanned aerial vehicle. The video data is video frame data recorded by the shooting device when the unmanned aerial vehicle flies and hovers. The flight attitude data can describe the flight attitude of the unmanned aerial vehicle at each time point, and the data can be one or more of flight gear, flight speed, rotation angle, flight height, obstacle distance, carried holder attitude and the like of the unmanned aerial vehicle. Specifically, the rotation angle of the unmanned aerial vehicle may be a Pitch angle (Pitch angle), a yaw angle (yaw angle), a roll angle (roll angle), and the like. The timestamp data is used for identifying the generation time of other data, and in the application, the timestamp data can identify the generation time of video data and flight attitude data and is used for synchronizing the video data and the flight attitude data.
The electronic equipment is communicated with the unmanned aerial vehicle, and video data, flight attitude data and timestamp data can be acquired from the unmanned aerial vehicle. The electronic equipment can acquire video data, flight attitude data and timestamp data in real time when the unmanned aerial vehicle flies; the shooting can be completed by the shooting device, and the video data, the flight attitude data and the timestamp data stored in the aircraft can be acquired after the unmanned aircraft returns.
Optionally, after the electronic device acquires the flight attitude data, denoising processing may be performed on the acquired flight attitude data. The denoising method can be selected according to the needs of those skilled in the art, for example, low-pass filtering or the like can be performed on the flight attitude data to remove data with sudden changes in the flight attitude data, such as data generated during the instantaneous jump of the flight speed, so that the clipping result is smoother and smoother. In addition, the denoising processing of the flight attitude data can also be performed by a processor of the unmanned aerial vehicle. The unmanned aerial vehicle can send the processed flight attitude data to the electronic equipment after denoising processing.
As an example, the electronic device performs step 120, and the process of clipping the video data based on the flight attitude data and the timestamp data can be seen in fig. 4, which includes the following steps:
step 121: judging whether the flight attitude data meets a preset clipping condition or not;
step 122: and splicing the video data corresponding to the time of the flight attitude data meeting the preset splicing condition to obtain the spliced video.
In step 121, the clipping condition can be set by a person skilled in the art according to actual requirements, and there are several possible clipping conditions listed here, which can be specifically any one or more of the following combinations:
(1) the flight gear of the unmanned aerial vehicle is a preset gear: the unmanned aerial vehicle has multiple flight gears, such as a common gear, a power gear, a motion gear, a manual gear, a rolling gear and the like, for different flight gears, the operation instruction of a user, the flight actions (yaw, pitch and rolling actions), the maximum flight speed and the maximum flight height which can be executed by the unmanned aerial vehicle can be different, and the user can select the flight gears according to the own needs. The preset gear may be a gear that allows the unmanned aerial vehicle to perform a high degree of freedom motion, or may be a gear that allows the unmanned aerial vehicle to fly at a higher speed, such as a sport gear, a manual gear, or a roll gear, without limitation.
(2) The rotation angle of the unmanned aerial vehicle is greater than a preset angle threshold value: as described above, the rotation angle of the unmanned aerial vehicle may include a Pitch angle, a yaw angle, a roll angle, and the like, and accordingly, the preset angle threshold may include a Pitch angle threshold, a yaw angle threshold, a roll angle threshold, and the like. The user can set the rotation angle of the unmanned aerial vehicle to be greater than the preset angle threshold value when the specified certain angle rotation angle is greater than the corresponding angle threshold value, for example, the user can set the rotation angle of the unmanned aerial vehicle to be greater than the preset angle threshold value only when the roll angle of the unmanned aerial vehicle is greater than 30 degrees, and the user does not pay attention to other two rotation angles; more than one rotation angle greater than the corresponding angle threshold value can be set, and the rotation angle of the unmanned aerial vehicle is considered to be greater than the preset angle threshold value, and no limitation is made here.
(3) The flight speed of the unmanned aerial vehicle is greater than a preset speed threshold value.
(4) The flight height of the unmanned aerial vehicle is greater than a preset height threshold value.
(5) The distance between the unmanned aerial vehicle and the obstacle is smaller than a preset distance threshold value.
(6) The attitude change of the holder on the unmanned aerial vehicle is greater than a preset attitude change threshold value: the unmanned aerial vehicle is because air resistance etc. when flying, the fuselage can inevitable shake, and in order to prevent the shake of fuselage from influencing shooting stationary degree of shooting device, the cloud platform can shake with fuselage shake frequency, amplitude unanimity, but with shake opposite direction's mode to steady shooting device. And in order to distinguish whether the attitude change of the holder is caused by a stable camera or the unmanned aerial vehicle has a large change of flying attitude, the condition that the shaking frequency of the holder is less than the preset frequency threshold value and the rotation amplitude of the holder is greater than the preset rotation amplitude threshold value can be used as the clipping condition. The change of the posture of the pan/tilt head may also be determined according to the change of the angle of the pan/tilt head at the Pitch angle, the yaw angle, and the roll angle, and the preset posture change threshold may also be set according to the above three angles.
(7) The variation amplitude of a control used for operating the unmanned aerial vehicle to fly on the electronic equipment is larger than a preset variation amplitude threshold value. The control can be a physical control such as a rocker and a thumb wheel; or virtual controls such as virtual rockers, virtual thumb wheels. As an example, this condition may be set to a change of the stick amount on the remote controller of more than 30%.
The preset gear, the speed threshold, the altitude threshold, the distance threshold, the frequency threshold, the rotation amplitude threshold, and the like may be set and modified by a user, or may be set by default in a program, which is not limited herein.
The above lists a plurality of selectable clipping conditions, and the user can self-select more than one clipping conditions as the preset clipping conditions. For example, the user may select only "the flight speed of the unmanned aerial vehicle is greater than the preset speed threshold" as the preset clipping condition, and may also select "the flight speed of the unmanned aerial vehicle is greater than the preset speed threshold", and/or "the rotation angle of the unmanned aerial vehicle is greater than the preset angle threshold", and/or "the distance between the unmanned aerial vehicle and the obstacle is less than the preset distance threshold" as the preset clipping condition.
The video data can be clipped by marking the video data, extracting the marked video data in the video data and splicing. Specifically, the flight attitude of the unmanned aerial vehicle at each time point is recorded due to the flight attitude data. For the flight attitude data meeting the preset clipping condition, the timestamp data corresponding to the flight attitude can be marked in the timestamp data. If the preset clipping condition is satisfied when the flight attitude data from the 2 nd minute to the 2 min 20 sec and the flight attitude data from the 3 rd minute to the 3 min 30 sec of the unmanned aerial vehicle are flown, the data from the 2 nd minute to the 2 min 20 sec and the 3 rd minute to the 3 min 30 sec in the time stamp data are marked.
And searching corresponding video data according to the marked timestamp data, and extracting the video data for splicing. The marked video data of 2 minutes to 2 minutes 20 seconds, and 3 minutes to 3 minutes 30 seconds can be found, as from the marked time stamp data. And extracting the two sections of video data, and splicing the two sections of video data to obtain the automatically edited video.
In an alternative embodiment, the automatic clipping method based on flight attitude data may further be combined with an existing automatic clipping method based on video content, that is, the automatic clipping method refers to the flight attitude and the video content at the same time.
Specifically, the automatic clipping method based on video content may be to recognize whether the video data contains a character scene or not and clip the video data containing the character scene by using technologies such as biometrics and scene recognition; the similarity between adjacent frames can be identified by utilizing an image identification technology, the moment when the similarity between the adjacent frames in the video data is greater than a preset similarity threshold value is marked, and the video data in a specified time period containing the moment is extracted for splicing. Those skilled in the art can implement the conventional automatic clipping based on video content, and the application is not limited thereto.
The combination of the two clipping methods can be that corresponding video data are clipped by referring to the flight attitude, and then the video data after the primary clipping is secondarily clipped by referring to the video content. The clips are first clipped with reference to the flight attitude or the video content, and are not limited herein. By combining the two clipping methods, the video data corresponding to the situation that the flight attitude meets the preset clipping condition and the video data identified based on the video content can be clipped, so that the problem that a wonderful picture is possibly omitted due to a single clipping mode can be solved, and the content of the clipped video is greatly enriched.
In one example, if the device performing the clipping operation is an unmanned aerial vehicle, the electronic device may also perform secondary clipping on the clipped video data after the unmanned aerial vehicle transmits the video data to the electronic device. For example, in order to save storage resources, the unmanned aerial vehicle only stores video data shot when the flying height is greater than 50 meters, and the video clipping method is executed to clip the video data recorded by the shooting device with the flying height greater than 50 meters. Thereafter, the unmanned aerial vehicle can transmit the flight attitude data, the time stamp data, and the once clipped video data to the electronic device. The user can further execute the video clipping method on the electronic equipment according to the requirement, and secondary clip out the video data shot when the flying speed is more than 20km/h or the distance from the obstacle is less than 2 m.
In addition, when playing back video on the electronic device, the played back video may be clipped video data, or video data which is marked based on the flight attitude data and the timestamp data but is not clipped, and only the video in the marked time period may be played during playback, for example, the video data in the 2 nd minute to 2 nd minute 20 second during flight is marked by using the above method, and the playback may jump directly to the time of 1 minute 57 second and then the time starts playing to 2 minutes 23 seconds, and then jump to the next marked time for playing.
By combining the above embodiments, it can be seen that the video editing method provided by the application automatically edits the recorded video based on the flight attitude data and the timestamp data, and can automatically edit the video data shot by the aircraft during high-difficulty actions such as high-speed flight, rolling, rotation and the like, so that the wonderful pictures which the user wants to leave are reserved. Especially for the traversing machine, different from the aerial camera, the traversing machine can carry out high-difficulty flying actions such as high-speed flying, large-moving-scene flying and the like, so that shot pictures are changed greatly, and some instant pictures are difficult to be identified accurately by image picture identification, especially for pictures shot by the traversing machine during high-speed flying and turning, and the pictures are wonderful pictures which users want to extract and reserve.
