Method and apparatus for the extraction and compression of surveillance information to facilitate high performance data fusion in distributed sensor systems
First Claim
1. In a surveillance system comprising a master processing system and one or more sensor systems, said sensor systems being distributed throughout a surveillance area and in communications with the master processing system, a surveillance method comprising the steps of:
- at the master processing system;
receiving data streams from the sensor systems;
analyzing the received data streams to determine characteristics of a target situated within the surveillance area; and
repeating the above receiving and analyzing steps; and
at the sensor systems;
collecting sensor specific stimulus (data);
pre-processing the collected data;
applying a matched extraction/compression scheme to the pre-processed data; and
transmitting the extracted/compressed data to the master processing system.

Abstract
A method and apparatus for the generic extraction and compression of surveillance information that facilitates high performance data fusion in distributed sensor systems. According to the method, multiple sensors (120[1] . . . 120[N]), distributed over a wide surveillance area (100), sense surveillance data of interest (310), optionally filter that sensed data (340), extract non-essential data (360) from the filtered data, compress in a manner specific to the extracted data (370) the extracted data for transmission and subsequently transmit (380) the compressed data to a “master” processing system (220) for integration/fusion with other transmitted compressed data streams originating from other sensors. Reductions in required data transmitted is on the order of 100:1.
