This invention relates to the field of UAV visual surveillance and target tracking technology, specifically disclosing a UAV dynamic target stabilization acquisition method based on motion pose decoupling. This method addresses the image disturbance problem caused by the synchronous motion of the UAV platform and the target. It constructs an accurate optical flow field model caused by the self-motion of the UAV platform by synchronously acquiring airborne images and UAV pose change information; then, it subtracts the self-motion component from the observed optical flow to obtain a compensated residual optical flow field that only represents the true motion of the target; based on this, it extracts the target's motion vector in the image plane and back-projects it to a unified world coordinate system to obtain the target's three-dimensional motion state; finally, it achieves stable tracking through a state estimator. This invention achieves motion decoupling at the algorithmic level, eliminating the need for a mechanical gimbal, and effectively improving the tracking stability and accuracy of UAVs for small moving targets on the ground in highly dynamic flight environments.
