A system includes a first and second digital imaging devices. Each digital imaging device is configured to capture digital images of a surface traveled by a vehicle. A digital image correlator is configured to (i) correlate a first digital image of the surface captured by a first digital imaging device at a first time and a second digital image of the surface captured by a second digital imaging device at a subsequent second time, and (ii) determine a correlation vector. The first and second imaging devices are separated by a known distance. A kinematics circuit is configured to determine in response to the correlation vector an incremental translation and rotation of the vehicle. The system includes a navigation circuit configured to combine at least two instances of the incremental translation and rotation into data indicative of travel by the vehicle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dead reckoning system for vehicles","description":"Described embodiments include a system and method.
