Abstract
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.
