    摘要: The sensor group(s) comprise a group of sensing nodes at a location. The location comprises spatial boundaries. Each of the sensing nodes comprise a sensor area. Each of the sensor group(s) based on: range limits of each of the sensing nodes; shared sensing areas of the sensing nodes; and intersections between the sensor area for each of the sensing nodes and the spatial boundaries. Acoustic signals are captured from an acoustic event via sensing nodes of sensor group(s). Solution(s) are generated by processing the acoustic signals. The solution(s) indicate the location of the acoustic event. A strength of solution compliance value is determined for solution(s). A refined solution is generated employing: sensor contributions of sensing nodes; and the strength of solution compliance value with the spatial boundaries and solution(s). A report comprising the location of the acoustic event is transmitted.

    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.

    摘要: A sequence of motion observations of a moving object are received from a first set of sensors. A first sequence of distance ratios are calculated based on the first sequence of motion observations. First transects are generated based on the first sequence of distance ratios. A first motion track of the moving object is produced based on: the first transects; and a map. A second set of sensors are determined employing the map. A second sequence of motion observations of the moving object are received from the second set of sensors. A second sequence of distance ratios for second pairs of the second set of sensors based on the second sequence of motion observations. Second transects are generated based on the second sequence of distance ratios. A second motion track is produced based on the first motion track, the second transects, and the map.
