Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The invention provides a video system for optimizing video through sound positioning, which has the working principle that the specific position of a sound source is detected through a sound positioning module, and then a central processing unit controls an adjusting module to adjust the video angle of a video module, so that the video module can carry out video at the optimal angle, and the aims of realizing automatic adjustment of the video angle and ensuring the video quality are fulfilled.
The present invention will be described in further detail with reference to examples and specific embodiments.
As shown in fig. 1, a video system for performing video optimization through sound localization includes a sound localization module, a central processing unit 2, a regulation module 3, a video processing module, a sound module, and an alarm module. Wherein:
