In this paper, we present an image rectification method for the multi-view image captured by a parallel multicamera arrangement. Since most multi-camera arrangements are manually adjusted, there exist misalignments with the camera positions and orientations. These misalignments cause geometric errors that can be a serious obstruction to three-dimensional (3D) image processing and applications. Moreover, different internal characteristics of cameras increase geometric errors. In order to minimize those geometric errors, we design an ideal multi-camera arrangement and then calculate the multi-view image rectifying transform (MIRT). Experimental results show that the proposed method reduces geometric errors efficiently without any visual distortion, and generates the rectified multi-view image in very short processing time.
