US 2019/0098401 A1 · PROCESSING OF SIGNALS FROM LUMINAIRE MOUNTED MICROPHONES FOR ENHANCING SENSOR CAPABILITIES

Abstract

The specification and drawings present a use of multiple microphones for increasing acoustic sensing capabilities by processing acoustic signals from the multiple microphones in outdoor luminaire mounted surveillance/sensor systems. For example, various embodiments presented herein describe signal processing means to utilize stereo/multiple microphones in a luminaire (such as an outdoor roadway luminaire) to provide enhanced information regarding the surroundings of the luminaire. The multiple microphone luminaire sensor processing system can provide a more environmentally robust and sensitive approach which can be, for example, resistant to environmental noise such as a wind noise, as well as capable of isolating specific sounds from the surroundings, e.g., in specific directions.

Dependent claims

A method for using a plurality of microphones in a sensor module of a luminaire, the method comprising:

receiving, by a computing module of the sensor module, information comprising a plurality of acoustic output signals from the corresponding plurality of microphones, and any of detection directionality and location for each of the plurality of microphones;
processing, by the computing module, using the received information, the plurality of acoustic output signals to:
identify a desirable acoustic signal at least in one of the plurality of acoustic output signals using analysis of the received plurality of acoustic output signals, and
correlate the acoustic output signals with any of the detection directionalities and locations of the plurality microphones.
