Abstract
Image information to be obtained from the target are distorted because they are on the curved surface. Existing techniques of image processing are designed for planar images, and are not suitable for distorted images. To apply existing techniques for distorted images, planation method is desired. This method needs 3D structure information to be stretched into plain surface, but estimated 3D information obtained by structure mesurement tools such as structure from motion techinique is represented with low resolution. In order to obtain planared image using low resolution 3D information, we proposed grid expantion technique with two sampled grids of different phases. Experimental results showes the effectiveness of our proposed method.
