| 摘 要： | 根据某型航空侦察CCD相机的工作原理,提出了一种适用于该相机图像的快速拼接方法.首先运用相机工作参数估计相连图像间仿射变换模型参数,进而初步确定图像重叠区域;然后在估计的重叠区域内采用互相关配准方法精确估计配准参数;最后采用双线性插值方法对图像重叠区域进行融合.实际运行结果表明,该方法不仅能有效减少图像拼接时间,降低图...

| Abstract: | A fast image mosaic method is proposed for an aerial reconnaissance CCD camera.In this method,parameters of affine transformation were first evaluated by using the work parameters of the camera,which can supply a rough registration area of images.Then,the image cross-correlation was employed to obtain a higher precision in the affine transformation parameters by searching this rough area.Finally,a bilinear interpolation method was used to fuse the overlapping area of images.Experimental results of this meth... |
