Abstract

A panoramic image is the image that captures a wide scope scene in horizontal direction. Various techniques had been studied to acquire this panorama image; a method to use a calibrated multi-camera system, a method to stitch multiple images, and a method to use a curved surface mirror and a wide-angle lens (omni-camera). However, there are problems in each method. In case of the multi-camera system, high precision calibration among multiple cameras is necessary and the system becomes complicated. In the stitching method case, we can use a normal digital camera, but overlapping areas between images cause discomfort at the stitched regions due to differences of brightness and colors between images caused by lighting condition and exposure change. In case of the omni-camera, we can capture panoramic images easily and directly, but we suffer from uneven resolution in the eye direction and overall low resolution of the captured images. Therefore in this paper, we propose a hybrid method which calibrates brightness and color and keeps high resolution by composing omni-camera images and normal-camera images. In addition, we study about registration techniques between a panorama image and a normal image.
