电子设备定向音频视频采集
摘要：
本文公开了一种装置。该装置包括壳体、电子电路以及音频‑视觉源跟踪系统。电子电路位于壳体中。音频‑视觉源跟踪系统包括第一视频相机和麦克风阵列。第一视频相机和麦克风阵列附接至壳体。音频‑视觉源跟踪系统被配置成从第一视频相机接收视频信息。音频‑视觉源跟踪系统被配置成至少部分地响应于所述视频信息而从麦克风阵列采集音频信息。音频‑视觉源跟踪系统可以包括附接至壳体的第二视频相机，其中第一视频相机和第二视频相机一起估计麦克风阵列的声束定向。
摘要（英）：

Disclosed herein is an apparatus. The apparatus includes a housing, electronic circuitry, and an audio-visual source tracking system. The electronic circuitry is in the housing. The audio-visual source tracking system includes a first video camera and an array of microphones. The first video camera and the array of microphones are attached to the housing. The audio-visual source tracking system is configured to receive video information from the first video camera. The audio-visual source tracking system is configured to capture audio information from the array of microphones at least partially in response to the video information. The audio-visual source tracking system might include a second video camera that is attached to the housing, wherein the first and second video cameras together estimate the beam orientation of the array of microphones.
