Claim:
1. A system comprising: a first digital imaging device and a second digital imaging device, each digital imaging device configured to capture multiple pixel two-dimensional digital images of a stochastic surface traveled by a vehicle, the first digital imaging device and the second digital imaging device coupled to the vehicle; a digital image correlator configured to (i) correlate a first digital image of the stochastic surface captured by the first digital imaging device at a first time and a second digital image of the stochastic surface captured by the second digital imaging device at a subsequent second time, and (ii) determine a correlation vector, wherein the first digital image acquired by the first digital imaging device and the second digital image acquired by the second imaging device; a kinematics circuit configured to determine in response to the correlation vector an incremental translation and rotation of the vehicle between the first time and the second time; and a navigation circuit configured to combine at least two instances of the incremental translation and rotation of the vehicle into data indicative of an acceleration, speed, distance, direction, or course traveled by the vehicle during a period of time.
