Abstract
The invention provides an unmanned aerial photography machine synchronous sound recording method. With the method adopted, when recording videos, an aerial photography aircraft can synchronously and precisely record on-site audios.
Description
Technical field
The present invention relates to the field of taking photo by plane of unmanned vehicle, especially, relate to a kind of unmanned aerial photography machine synchronization method.
Background technology
Its small and exquisite structure landing of unmanned aerial photography aircraft is convenient, and outstanding handling and stability brings accurate high-quality picture, for video display creation provides the scheme of taking photo by plane safer, convenient, fast, at a low price.And wherein major issue be the sound collected and recorded of the synchronization of aerial video its entirely for noise and wind that power blade sends are made an uproar, make the processing of postproduction of movies track can only load the audio frequency of ground admission, and it is synchronous to complete the sound picture of the video of taking photo by plane in just sincere justice.
Summary of the invention
For the deficiency existing in prior art, the invention provides a kind ofly in the aircraft recorded video of taking photo by plane, the unmanned aerial photography machine synchronization method of synchronous precision studio audio frequency, solves the take photo by plane problem of track difficulty of postproduction of movies processing.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
(1) take photo by plane on aircraft video camera is installed, video camera is recorded controller, receiver of remote-control sytem.The recording and stop of remote control receiver controls video camera, receiver of remote-control sytem is controlled by terrestrial transmitters.
(2) at surface deployment sound pick-up outfit, receiver of remote-control sytem.The recording and stop of remote control receiver controls sound pick-up outfit, remote-controlled receiver is controlled by terrestrial transmitters.
(3) tranmitting frequency of terrestrial transmitters and video camera receiver of remote-control sytem, sound pick-up outfit receiver of remote-control sytem same frequency, sending a start signal can instantaneous trigger video and recording synchronous recording, and sending that a shutdown signal can open can instantaneous trigger video and the close synchronously of recording.
(4) be often recorded to and stop once, video camera generates a video file, and sound pick-up outfit generates an audio file, can be by sequence number and recording time index, and carry out postproduction of movies audio frequency and video editor.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment
The present invention includes following steps:
The first step: install on device that video camera, video camera are recorded controller, the device receiver of remote-control sytem of taking photo by plane taking photo by plane, send and record or when stop signal, the device remote control receiver controls of taking photo by plane video camera is recorded controller, and triggers video camera and record or close in terrestrial transmitters.
Second step: at surface deployment sound pick-up outfit, recording receiver of remote-control sytem, in the time that terrestrial transmitters is sent recording signal, recording remote control receiver controls sound pick-up outfit controller, and trigger recording or closing of sound pick-up outfit.
The 3rd step: terrestrial transmitters is sent the moment of a recording signal, the device receiver of remote-control sytem of taking photo by plane is received signal, and controls video camera and record controller, triggers picked-up picture.The recording receiver of remote-control sytem on ground also receives recording signal simultaneously, triggers sound pick-up outfit recording audio, and recording occurring continuously to file.
The 4th step: terrestrial transmitters is sent a moment that stops recording signal, the device receiver of remote-control sytem of taking photo by plane is received signal, and controls video camera and record controller, stops absorbing picture.The receiver of remote-control sytem of ground recording simultaneously also receives stop signal, triggers sound pick-up outfit and stops recording audio, and write audio file.
Because picture pick-up device and sound pick-up outfit are subject to the control of a reflector, can realize and record simultaneously or stop simultaneously.Sound pick-up outfit is only in ground recording, the noise that the device flight that can not be subject to taking photo by plane forms and greatly improved recording quality.The file that picture pick-up device and sound pick-up outfit form is on the other hand also real-time and synchronous, and document time length one makes, and the rail that closes that can conveniently complete audio frequency, video in post-production is made.Greatly raise the efficiency and accuracy.
Above-described embodiment is preferably execution mode of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present invention and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection scope of the present invention.
Claims (4)
1. on device, install that video camera, video camera are recorded controller, the device receiver of remote-control sytem of taking photo by plane taking photo by plane; The device receiver of remote-control sytem of taking photo by plane is controlled by terrestrial transmitters, and the device remote control receiver controls of taking photo by plane video camera is recorded controller, and controls video camera and record or close.
2. at surface deployment sound pick-up outfit, recording receiver of remote-control sytem; Recording receiver of remote-control sytem is controlled by terrestrial transmitters, recording the recording and stop of remote control receiver controls sound pick-up outfit.
3. terrestrial transmitters is sent the moment of a recording signal, and the device receiver of remote-control sytem of taking photo by plane is received signal, and controls video camera and record controller, triggers picked-up picture; The recording receiver of remote-control sytem on ground also receives recording signal simultaneously, triggers sound pick-up outfit recording audio, and recording occurring continuously to file.
4. terrestrial transmitters is sent a moment that stops recording signal, and the device receiver of remote-control sytem of taking photo by plane is received signal, and controls video camera and record controller, stops absorbing picture; The recording receiver of remote-control sytem on ground also receives stop signal simultaneously, triggers sound pick-up outfit and stops recording audio, and write audio file.
