Step 102, the voice data is blended into the video data.
In the present embodiment, as an alternative embodiment, the voice data is blended into the video data includes：
If the voice data is all the way, according to synchronous time shaft, the voice data is added to the video
In data.
It is known technology on voice data is blended into video data, detailed description is omitted here in the present embodiment.
In the present embodiment, if only unique audio collecting device (camera of built-in audio capture card) in scene,
What then intelligent gateway received is voice data all the way.When autonomous actions equipment performs flight and performs video capture, audio
The voice data of collection is back to intelligent gateway by collecting device in real time, meanwhile, autonomous actions equipment is also by the video counts of collection
Intelligent gateway is back to when factually, since intelligent gateway possesses executive program and computing capability, thus, intelligent gateway is according to video
The time shaft of data and voice data carries out audio and video synthesis, the audio, video data synthesized so that user is browsing synthesis
Audio, video data when, can effectively lift the viewing experience of user.
In the present embodiment, due to performing time synchronization to autonomous actions equipment and audio collecting device in advance, thus,
The audio, video data synthesized using intelligent gateway can be based on same time shaft so that the synchronism of audio ＆ video obtains preferably
Ensure.
In the present embodiment, as an alternative embodiment, if there are multiple audio collecting devices, (built-in audio is adopted in scene
The camera of truck), then need to use decision rule set in advance, to judge the sound gathered using which audio collecting device
Frequency evidence, is synthesized with the video data with autonomous actions equipment.
In the present embodiment, as another alternative embodiment, the voice data is blended into the video data includes：
A21, if the voice data is multichannel, sequentially extracts the power noise in multi-path audio-frequency data；
In the present embodiment, since the sound property of autonomous actions equipment rotor is single, after multi-path audio-frequency data is received,
The power noise in multi-path audio-frequency data can be extracted respectively according to the characteristic of power noise.
In the present embodiment, power noise includes but not limited to：Rotor noise and roller noise etc..

If all the way in voice data, the power noise of autonomous actions equipment is too strong (being greater than or equal to noise intensity second threshold) for certain,
Showing that autonomous actions equipment is nearer from audio collecting device so that the voice data of audio collecting device collection is second-rate,
Not use；If in a certain voice data, the power noise of autonomous actions equipment is too low (to be less than or equal to noise intensity first
Threshold value), show autonomous actions equipment from audio collecting device farther out, show the audio collecting device collection voice data with from
The corresponding voice data of flight locations where main action equipment is also not used there may be larger difference.
In the present embodiment, noise intensity first threshold and noise intensity second threshold, i.e. noise intensity threshold range can be according to
It is configured according to actual needs, so as to pass through this kind of mode, it can be determined that go out relatively optimal voice data.
In the present embodiment, if greater than pre-set noise intensity first threshold and it is less than pre-set noise intensity
The power noise intensity of second threshold has multiple, then from corresponding voice data, randomly selects and wait to close described in a voice data
Into voice data all the way；Or, noise intensity first threshold and the arithmetic mean of instantaneous value of noise intensity second threshold are calculated, then calculate
The absolute value of the difference of power noise intensity and arithmetic mean of instantaneous value, chooses and is treated described in the minimum corresponding voice data conduct of absolute value
The voice data all the way of synthesis, in this way, relatively optimal voice data can be obtained.
In the present embodiment, as an alternative embodiment, if meeting to be more than noise intensity first without power noise intensity
Threshold value and it is less than noise intensity second threshold, then can calculates the arithmetic of noise intensity first threshold and noise intensity second threshold
Average value, then the absolute value of the difference of power noise intensity and arithmetic mean of instantaneous value is calculated, choose the minimum corresponding audio of absolute value
Data are as the voice data all the way to be synthesized.
A23, according to synchronous time shaft, the voice data all the way to be synthesized is added in the video data.

A31, obtains distance of each audio collecting device at a distance of the autonomous actions equipment respectively；
In the present embodiment, if audio collecting device is integrated with wifi module, for example, wifi cameras, autonomous actions are set
It is standby itself also to carry wifi module, since intelligent gateway possesses wireless routing function in itself, then it can use wifi positioning skills
Art determines which audio collecting device is in nearest position from autonomous actions equipment, so that it is determined that being set using the audio collection
The video data that the voice data of standby collection is gathered with autonomous actions equipment is synthesized.
If audio collecting device does not possess the wifi module that can be positioned, can be noted to intelligent gateway
During volume, registered with place orientation.For example, parlor audio collecting device is registered as, and kitchen audio collecting device, balcony audio
Collector etc..Autonomous actions equipment itself can use wifi module positioning to determine orientation, once it is determined that there are corresponding in orientation
Audio collection device (equipment), then using the voice data of the audio collection device.
A32, the most short corresponding voice data of selected distance, is added in the video data.
In the present embodiment, as yet another alternative embodiment, the voice data is blended into the video data includes：
A41, obtains distance of each audio collecting device at a distance of the autonomous actions equipment respectively；
A42, obtains audio collection of the distance in pre-set first distance threshold to second distance threshold range and sets
It is standby, the voice data of audio collecting device collection is therefrom chosen as the voice data all the way to be synthesized.
In the present embodiment, propose a kind of autonomous actions equipment used suitable for environment, utilize the existing audio of environment
Collecting device, carries out audio collection, and synchronizes synthesis with the video of autonomous actions equipment collection, hence for using autonomous
For the user of action equipment, the purpose of autonomous actions equipment collection audio is realized.
