摘要： The present invention aims to simplify stitching algorithm which generates horizontal panoramic image. The image pickup device of the present invention comprises a plurality of lenses and positioning means. Said positioning means positions each lens so that the FOV (Field Of View) intersection points of all lenses are aligned in vertical direction. Accordingly, the horizontal parallax does not exist in the image picked up by the camera system and the stitching point remains the same for the objects at different distances.

摘要： The invention provides a method for improving image stitching accuracy and a device for implementing the same, which apply to the multi-camera system for wide-angle image generation. Lens distortion causes mismatches of the features in the overlapping region of the images captured by the multi-camera system. As a result, the mismatches on the stitched wide-angle image are visible. The method and device for improving image stitching accuracy correct the lens distortion before stitching the images captured by the multi-camera system, so that the features in the overlapping region are matched and a seamless wide-angle image is generated by the stitching engine.
