Description
Technical field
The invention belongs to the field of taking photo by plane, particularly relate to a kind of aerial device based on unmanned vehicle and method of taking photo by plane thereof.
Background technology
At present, in the various scene of shooting, during as the scene such as party, ceremony, in order to show grand scene, usually adopt the means getting a bird's eye view shooting, therefore need to use unmanned vehicle to take photo by plane, it is a collection singlechip technology that unmanned vehicle is taken photo by plane, sensor technology of taking photo by plane, GPS navigation take photo by plane technology, many technology such as service technology, flight control technology, task control technology, programming technique are taken photo by plane in communication and rely on the high-tech product of hardware, and its filmed image has the advantage of high definition, large scale, small size, high Up-to-date state.And unmanned vehicle provides easy to operate for photography of taking photo by plane, be easy to the remote sensing platform of transition; Taking off landing is less by place restriction, and on playground, highway or other openr ground all can landings, and its stability, fail safe are good, and transition etc. are very easy to; The outstanding feature that small portable, low-noise energy-saving, efficiently motor-driven, image definition, lightness, miniaturization, intelligent unmanned vehicle are especially taken photo by plane.Apply the monitoring that many rotor wing unmanned aerial vehicles carry out specific region and can worry personal security, also need not worry the muscle power restriction of pilot.
The one shooting means that current unmanned vehicle is taken photo by plane are direct shootings, and usually carry the Rotation Noise of screw wing in the video of its picked-up secretly, this makes video audio very poor, another means is then adopt to take photo by plane the special sound pick-up outfit be separated with unmanned vehicle, and directly at ground admission scene sound, and the audio frequency in video aerial photography device absorbed is abandoned, and the audio frequency of being enrolled on ground imports in video, is integrated into new video, for this kind of method, current making comparatively bothers, main cause is: when the audio frequency that the video take aerial photography device and ground enroll is integrated, need to carry out " to accent " work, namely, make ground audio & video picture synchronization, this work extremely tests the patience of staff and careful, first need to find in video the sounding picture that suitable, then certain moment will heuristically moved to the audio time point of the relative sound of this generation picture in this generation picture, then other picture moment is proofreaded and whether audio time point coincide, if misfit, also need fine setting, until audiovisual realizes the Complete Synchronization of audio & video picture, although this kind of means can improve aerial sound as can be seen here, make efficiency is slower.
Patent documentation CN102143346 discloses a kind of cruise shooting storage method, and it comprises: to central processing unit input audio signal; At least one road vision signal is inputted to central processing unit; Described each audio signal, vision signal, according to the mode of timing synchronization, are sent to multichannel voice frequency video collector by described central processing unit; Described multichannel voice frequency video collector gathers described audio signal, vision signal, and obtain a road collection signal, described collection signal comprises described audio signal, video signal information; Described collection signal is carried out audio/video coding; Store described audio/video coding data.Multichannel voice frequency vision signal is synchronously processed by central processing unit and is synthesized on a road collection signal by this patent, thoroughly changes the mode of current multichannel audio-video frequency signal time-dividing storage, reaches real-time storage and complete reservation recorded broadcast information.But this patent only remains voice data and video data, automatically form valuable displaying content, the later stage also needs to carry out numerous and diverse Prof. Du Yucang audio frequency and video, and cannot ensure that the audio frequency and video of Complete Synchronization produce, and make efficiency is low and cannot ensure precision.
Patent documentation CN103673996 discloses a kind of method being convenient to obtain good aerial sound, comprises the steps: one, aerial photography device is installed camera, communicator of taking photo by plane; Described communicator of taking photo by plane is controlled by described camera; Two, at surface deployment sound pick-up outfit, described sound pick-up outfit comprises a trigger module that can trigger it and record immediately and cut out immediately; Described trigger module is controlled by a recording communicator; Three, described aerial photography device is opening the moment of camera, and communicator of taking photo by plane described in triggering sends an enabling signal to described recording communicator; Described recording communicator triggers sound pick-up outfit by described trigger module immediately and starts recording after receiving described enabling signal; Four, described aerial photography device is closing the moment of camera, and communicator of taking photo by plane described in triggering sends a shutdown signal to described recording communicator; Described recording communicator triggers sound pick-up outfit by described trigger module immediately and closes recording after receiving described shutdown signal.This patent can realize synchronous opening/closing between camera and sound pick-up outfit, but its range of application is narrow, only can record the corresponding audio collection of a video acquisition, and the situation of the corresponding multiple audio collection of video acquisition or the corresponding multiple audio collection of multiple video acquisition can not be recorded, user can not choose the voice data of expectation to floor as required and video data forms required audio frequency and video.
Patent documentation CN104038716 discloses and install video camera in aerial photography device, video camera records controller, aerial photography device receiver of remote-control sytem; Aerial photography device receiver of remote-control sytem is controlled by terrestrial transmitters, and controller recorded by aerial photography device remote control receiver controls video camera, and controls video camera recording or close.This patent is often recorded once, and video camera generates a video file, and sound pick-up outfit generates an audio file, by sequence number and recording time index, and can carry out postproduction of movies audio frequency and video editor.But cannot form valuable displaying content automatically, the later stage also needs to carry out numerous and diverse Prof. Du Yucang audio frequency and video, and user can not choose the voice data of expectation to floor as required and video data forms required audio frequency and video.
Disclosed above-mentioned information is only for strengthening the understanding to background of the present invention in the background section, therefore may comprise the information not being formed in prior art known to a person of ordinary skill in the art.
Aerial device of the prior art only completes independent Audio and Video record respectively, synchronously made by artificial post-processed, by post-production and synchronously realize video/audio data integration need operated by specialist tools by professional, and due to video, the nonsynchronous situation of audio data collecting may be very complicated, even, these Audio and Video data may be by completely asynchronous, multiple sporadic data bags of different duration are formed respectively, so this integration editing work is very complicated, the audio frequency and video Complete Synchronization made can not be ensured.Traditional aerial device cannot in the situation of the corresponding multiple audio collection of video acquisition or the corresponding multiple audio collection of multiple video acquisition, audio frequency and video required for automatic generation, therefore, in the art, be badly in need of a kind of by one or more video of gathering and the aerial device of the automatic synthesized voice video of one or more audio frequency and method of taking photo by plane thereof, reach Complete Synchronization and the high technique effect of make efficiency.
