Improved Harris Corner Detection Method Based On Embedded Image Stabilization System

针对传统电子稳像平台的缺陷,设计了一种基于改进Harris角点检测的进行运动估计的FPGA稳像系统。针对FPGA结构特点以及Harris算法理论结构,对算法进行了必要的改进。该系统还完成了运动估计和运动补偿部分的硬件设计,使得视频序列帧间存在平移和旋转时能够消除这种运动。研究结果证明,该系统基本能消除随机抖动。

For the traditional shortcomings of electronic image stabilization platform ,a image stabilization based on FPGA which using an improved Harris comer deteetion method for motion estimation is designed in this paper. By taking full account of the structure of FPGA and Harris comer detection theory,it is necessary to improve the algorithm. The motion estimation and motion compensation module is designed,in order that it can eliminate the existence of inter-frame translatinal and rotational motion. The results prove that this system can basically eliminate random jitter.
