| Abstract: | As for large sized workpiece that exceeds the FOV(Field of View) of the camera,a series of images have to be taken and image mosaic must be performed to form a panorama of the object.To realize the automatization of image acquisition and image mosaic,a three-coordinate(x-y-z) motion control worktable has been developed to locate the camera which has a fixed focal length.The general principle of image mosaic,the scheme of template matching based on mutual information measure were explained.Meanwhile,optimization of algorithms was discussed. |
