Abstract:
(EN) Provided in an embodiment of the present invention are a method and apparatus for video and audio synchronization, and an unmanned aerial vehicle. The method comprises: acquiring video information photographed by a video photographing apparatus installed at an unmanned aerial vehicle, and acquiring audio information recorded by a recording apparatus, wherein the video photographing apparatus and the recording apparatus are synchronized in time; and performing alignment of the video information and the audio information according to timestamp information included in the video information and timestamp information included in the audio information. The invention realizes automatic alignment and synchronization of video information and audio information, thereby increasing synchronization efficiency.
(FR) Selon un mode de réalisation, la présente invention concerne un procédé et un appareil destinés à une synchronisation vidéo et audio et un véhicule aérien sans pilote. Le procédé consiste à : acquérir des informations vidéo photographiées par un appareil photographique vidéo installé au niveau d'un véhicule aérien sans pilote, et acquérir des informations audio enregistrées par un appareil d'enregistrement, l'appareil photographique vidéo et l'appareil d'enregistrement étant synchronisés dans le temps ; et effectuer un alignement des informations vidéo et des informations audio selon des informations d'horodatage incluses dans les informations vidéo et des informations d'horodatage incluses dans les informations audio. L'invention réalise un alignement automatique et une synchronisation d'informations vidéo et d'informations audio, ce qui permet d'augmenter l'efficacité de synchronisation.
