Abstract

The application discloses an audio-video data synchronization method, a device and a system. The method comprises the following steps: acquiring audio-video data; acquiring distance; computing transmission time; updating the timestamp of the audio data; and synchronizing the audio-video data according to the updated timestamp. The device comprises an audio acquisition module, a video acquisition module, a distance acquisition module, a time computing module, a time updating module, and a data synchronization module; the system comprises a camera for acquiring video data, audio equipment for acquiring the audio data, a distance sensor arranged on the audio equipment for acquiring the distance, and control equipment respectively connected with the camera, the audio equipment and the distance sensor and used for receiving the data, computing the time, updating the timestamp and synchronizing the data. By using the method disclosed by the embodiment of the invention, the synchronization accuracy of the audio data and the video data is improved.

Description

technical field [0001] The present application belongs to the field of intelligent information processing, and in particular relates to a method, device and system for synchronizing audio and video data. Background technique [0002] UAV is a kind of unmanned aircraft controlled by wireless remote sensing equipment and self-contained control program control device. In recent years, with the rapid development of UAV miniaturization technology, UAV technology has been widely used in the field of video recording. [0003] At present, when using drones for video recording, video data and audio data are collected separately. Afterwards, the audio data and the video data are synchronized according to the time stamp of the audio data and the time stamp of the video data. [0004] However, according to this audio and video data synchronization method of the prior art, that is, the UAV recording and video recording are processed separately, and when the audio and video data is play...
