A lens control method and system for an image acquisition device based on sound detection
By using an image acquisition device based on sound detection, the direction of the sound source is determined by the ambient audio signal and the lens control parameters are calculated. This solves the problem of lens adjustment in complex environments and achieves efficient and accurate monitoring results.

AI Technical Summary
Existing cameras struggle to quickly and accurately adjust their lens orientation in complex environments to respond to dynamic changes and uncertain target locations.
By using an image acquisition device based on sound detection, the direction of the sound source is determined by the ambient audio signal, and control parameters such as lens turning angle, speed and focal length are calculated based on the direction of the sound source and audio characteristics to achieve automatic lens adjustment.
It improves the camera's responsiveness and directional stability in complex environments, ensuring that the lens is accurately aimed at the target sound source, thereby enhancing the monitoring efficiency and accuracy of the surveillance system.
