Steerable sensor array system with video input

摘要

Disclosed is a video controlled beam steering mechanism for an adaptive filter in a sensor array system that receives input from a target and applies an averaging filter and appropriately steers the beam. An adaptive filter is then used if the SNR of the output of the averaging filter reaches a threshold.

1. A sensor array device, comprising:
a sensor array having at least two sensors, the sensor array having one or more channels having as its output audio signals; a video camera having as its output a video signal and an object tracking reference signal; a processor receiving the audio signals from the sensor array and the object tracking reference signal from the video camera; and an adjustable beamformed audio capture region defined by said processor according to the audio signals and the object tracking reference signal, wherein a beam of said adjustable beamformed audio capture region is adjusted based on the audio signals and the object tracking reference signal and applying an adaptive filter to a filtered signal wherein coefficients of the adaptive filter are updated based on the adjusted beam.
