ACOUSTIC SOURCE LOCALIZATION IN CONFINED SPACES

摘要

The source of an acoustic even is located. Spatial boundaries for a location are determined. Sensing nodes are placed at the location. The intersection between a sensor area for sensing nodes and spatial boundaries is found. Sensor group(s) of sensing node(s) are determined, based at least in part, on sensing node range limits and shared sensing areas. Solution(s) are generated by processing acoustic event detections based on a multi-sensor fusion of sensor group(s). Solution(s) are refined employing sensor contributions based on a strength of solution compliance value with the spatial boundaries and advancing optimal solutions. Solution(s) are routed to a hub for integration with other services.
