Embodiment 1

[0031] see figure 1 , figure 1 It is a schematic flow chart of an embodiment of the method for acquiring on-site sounds of drones in the present invention. Such as figure 1 As shown, this embodiment includes:

[0032] Step 101: collecting sound signals of the working environment of the drone;

[0033] The executing subject of this embodiment may be a device with recording function and sound filtering function, and the device may be an internal module of the drone, or an external device installed on the drone body.

[0034] There are many kinds of working environments for drones, such as concerts, filming locations for film and television dramas, emergency rescue sites, farmland, national border environments, and so on. The sound signal of the drone's working environment includes the live sound of the working environment and the noise caused by the drone's work. The noise caused by the working of the drone includes the sound made by the functional modules of the drone body...

Embodiment 2

[0045] In the embodiment of the present invention, there is also provided a method for realizing video with sound of the drone. On the basis of the above-mentioned on-site sound acquisition method, the method also includes: acquiring the video picture of the working environment of the drone; The live sound of the environment and the video picture are synchronously synthesized to obtain a video with sound.

[0046]see figure 2 , figure 2 It is a schematic flow chart of an embodiment of the method for realizing video with sound of the drone of the present invention. Such as figure 2 As shown, this embodiment includes:

[0047] Step 201: collecting sound signals of the working environment of the drone, and obtaining video images of the working environment of the drone;

[0048] Please refer to the description in step 101 for collecting the sound signal of the working environment of the drone in step 201 . In this embodiment, not only the sound signal of the working enviro...

Embodiment 3

[0060] In an embodiment of the present invention, a live sound acquisition device for a drone is also provided. see image 3 , image 3 It is a structural schematic diagram of an embodiment of the UAV on-site sound acquisition device of the present invention. Such as image 3 As shown, this embodiment includes:

[0061] Acquisition module 310, for collecting the sound signal of unmanned aerial vehicle working environment;

[0062] The on-site sound acquisition device of the drone can be an internal module of the drone, or an external device installed on the fuselage of the drone. The acquisition module may include a sound sensor for recording the sound signal of the working environment of the drone.

[0063] The first acquisition module 320 is used to acquire the noise caused when the drone is working;

[0064] The first acquisition module may include a sound sensor, which is used to acquire the noise caused by the drone in real time. Specifically, the noise caused by th...

Abstract

An embodiment of the invention discloses an unmanned aerial vehicle (UAV) field sound acquisition method, an audio video realization method and related devices. The audio video realization method comprises the steps of: acquiring a sound signal of a UAV working environment; acquiring noise caused by the UAV in operation; filtering out the noise from the sound signal to obtain field sounds of the UAV working environment; acquiring video images of the UAV working environment; and synchronously synthesizing the field sounds and the video images of the UAV working environment to obtain an audio video. The UAV field sound acquisition method, the audio video realization method and the related devices can enable a user to shoot the audio video through operating a UAV, and the user experience is enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unmanned aerial vehicles, and in particular to a method for acquiring on-site sound of an unmanned aerial vehicle, a method for realizing audio and video, and related devices. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. UAVs are currently used in aerial photography, agriculture, plant protection, selfies, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting, and romance. The use of UAV itself has been expanded, and developed countries are also actively expanding industry applications and developing UAV technology. [0003] However, when the existing unmanned aerial vehicle system shoots a video, it only records the video picture, and can...
