| 摘 要： | 相位相关算法是目前图像匹配应用最广泛的算法之一。具有配准精度高、抗干扰能力强和易于硬件实现等优点。将其应用到视频实时拼接当中,并根据图像傅里叶变换的旋转特性及视频拼接的特点,对存在偏移及旋转关系视频帧图像的配准方法进行相应的优化。能够在基本不影响配准结果的情况下,实现了减少计算量的目的。

| Abstract: | Phase Correlation Algorithm(PCA) is widely used as image matching method.It has the advantages of high registration accuracy,strong anti-interference ability and ease of hardware implementation.It to the real-time video mosaic is used.According to the characteristics of video mosaic and rotation characteristics of the image Fourier transform,a modified phase correlation registration method is proposed.It can achieve the purpose to reduce the amount of calculation,and does not affect the results of registration of video frame images which have offset and rotation of the relationship. |
