External microphone for an unmanned aerial vehicle

Abstract

A videography drone can communicate with a microphone device. The videography drone can receive spatial information and audio data from a remote microphone device (e.g., a remote tracker, a mobile device running a drone control application, and / or a standalone audio recording device separate from the videography drone without drone control functionalities). The videography drone can utilize the spatial information to navigate the videography drone to follow the remote microphone device. The videography drone can stitch a video segment captured by its camera with an audio segment from the received audio data to generate an audio / video (A / V) segment. The stitching can be performed by matching spatial or temporal information (e.g., from the received spatial information) associated with the audio segment against spatial or temporal information associated with the video segment.

Description

technical field

[0001] At least one embodiment of the present disclosure relates generally to unmanned aerial vehicles (UAVs). Background technique

[0002] UAVs for consumers have traditionally been limited to entertainment as toys or as hobbyist collectibles. More recently, however, UAVs have been used for personal photography and videography. UAVs may be equipped with portable power sources and image capture devices, such as cameras or other types of sensors. For example, when there are no overhead obstacles, photographers or videographers can use UAVs to photograph or film athletes participating in outdoor activities. UAVs can also be used to record special occasions such as weddings, engagement proposals, and other events that may take place in open spaces. These applications require video recording along with audio to fully capture the moment. Conventional UAVs carry cameras and capture audio from the air, which is very low quality due to the noise from the propell...
