摘要
经典的相位法易受高频噪声影响,且计算量大,难以满足实时性要求。提出了基于提升小波变换和离线预建立相关归一化系数与旋转角度对应关系数据库的快速鲁棒运动估计方法。试验结果表明,该方法在保持较高估计精度的情况下,具有较快的估计时间和较好的鲁棒性。
Because classic phase correlation is easily affected by high frequence noise and has tremendous calculation,it isn 't fit for the requirement for real time.A fast and robust motion estimation method based on lifting wavelet transformation and beforehand establishment of data base of correlation coefficient and rotation angle.The emulation indicates that this method not only keep the high estimation precision,but also has less management time and more robust character.
