Detection And Tracking From Wide-Area Video Sources
Metron’s LandTracker software detects and tracks vehicles and dismounts within a wide-area imagery sensor footprint (e.g., 4km x 4km). Originally developed under Small Business Innovation Research funding and enhanced under subsequent DoD contracts, the overall capability has four technical components:
- Build 3D structure from motion using epipolar geometry-based methods;
- Perform fine-grain geo-registration using Fourier-based Rotation, Scale, and Translation (RST) methods;
- Extract foreground targets based on deviations from a statistical model of the background at the individual pixel level; and
- Associate contacts into tracks using a Markov-Bayes Particle Filter approach.
