ESARR

Situational Awareness (SA) systems leveraging Global Positioning Systems (GPS) and Geographical Information Systems (GIS) have become a mainstay for military vehicles, troops, and even unmanned systems (such as unmanned ground vehicles (UGVs)). Unfortunately, in urban, semi-urban or canopied terrain GPS signals can be difficult or impossible to receive consistently. New and alternative tools to enhance situational awareness are needed to fill this gap. The US Army has contracted Quantum Signal to develop ESARR: a tool for enhanced situational awareness via road sign recognition. Road signs can potentially serve as an alternative to GPS in these environments - by definition, they are designed to provide information related to location. When complete, the system will provide enhanced SA to the warfighter by:

  1. Capturing & processing road sign images in stills/video & extracting information from them;
  2. Relating the extracted information to GIS data to ascertain position (i.e. geo-bounding);
  3. Efficiently communicating this information back to the soldier in a manner that is timely and informative.

The system is based on a combination of advanced image processing techniques and will be able to perform these functions robustly under a variety of conditions from video in real-time. ESARR is being developed for defense applications, and will also be available for advanced safety and telematics systems in the automotive industry.
