1. A method for real time registration of two video images from two cameras, comprising the steps of: measuring an angle rate of change and attitude change of the two cameras; providing an estimate of relative change between the two cameras based on measured attitude change, wherein the estimate of relative change is utilized in initial image registration process to reduce processing load needed to keep two image frames registered; providing an estimate of relative change between the two cameras based on measured angle rate of change; and registering two video images based on the estimated relative change between two cameras based on measured angle rate of change.
