英文摘要：

Image stabilization is the key for accurate docking operations of robots with vision. The whole algorithm of image stabilization is established, including images kinematics model, KLT feature pixels detecting, SAD feature pixels matching and filters. Kalman and FIR filters are designed for smoothing images motion parameters and built in MATLAB. Simulation of filter of motion un-intended parameters is implemented to indicate removing jitter effect. Kalman filter is compared with FIR filter. Comparison curves and tables are given, which demonstrate that Kalman filter is better than FIR in robot vision image stabilization process. Based on VC＋＋ and OpenCV, image stabilization software is programmed, and experiments are completed on double moving robots docking operation platform. The algorithm running time is less than the sampling period, and the precision and real-time demands are contented.
