Real-time synchronous transmission system for audios and videos aerially photographed by unmanned aerial vehicle

Abstract

The invention discloses a real-time synchronous transmission system for audios and videos aerially photographed by an unmanned aerial vehicle. The system comprises the components of an unmanned aerial vehicle terminal which comprises a video acquisition unit, a video transmission unit, an audio acquisition unit and an audio transmission unit; and a video control terminal which comprises a video storage unit, a video display unit, an audio storage unit, an audio playing unit and an audio / video synchronization unit. The video / audio storage unit is provided with a plurality of video / audio storage modules for successively storing videos / audios. When the used space of the current video / audio storage module is larger than a preset spatial value, the video / audio is stored into a next video / audio storage module. Furthermore when the next video / audio storage module is the first video / audio storage module, the preset spatial value is doubled automatically. The real-time synchronous transmission system is advantageous in that small number of transmission faults is realized; a user can master the audios and videos photographed by the unmanned aerial vehicle in time; and furthermore high synchronism of the audios and videos is realized.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, and more specifically, the present invention relates to a real-time synchronous transmission system of unmanned aerial vehicle audio and video. Background technique [0002] UAV, also known as unmanned aircraft, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. At present, when users use drones for aerial photography and other applications, they usually use the drone to shoot the current environmental scene, and save the captured environmental images in the memory card. After the shooting is completed, take out the drone from the memory card The environmental image captured by the UAV, although this method can capture the required environmental image, but the user needs to wait for the UAV to complete the entire shooting before obtaining the required environmental image from the memory card. The content captured by the drone c...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a real-time synchronous transmission system for UAV aerial photography audio and video in view of the above-mentioned defects in the prior art, so as to overcome the problem in the prior art that the user needs to wait for the UAV to complete the whole process of shooting from the storage. The required environmental images are acquired on the card, and the content captured by the drone cannot be understood in time, and video transmission often fails, and there are only technical defects such as no audio and video or audio and video content being out of sync.
