Abstract Based on the 2-D dynamic displacement field model, the dynamic displacement model is extended from 2-D to 3-D. It realizes the description for the motion state estimation of the target in the depth direction of the sight field. It provides a gradually description process for distorted image sequence from estimating plane displacements to estimating spatial motion state. Compared to other video tracking techniques, based on the 3-D dynamic displacement field model, it has been implemented to stabilize the tracking sequence and estimate the target’s motion state.
