Cylindrical Panorama Using the Tilt of a Camera

We propose a method for extending the vertical field of view when constructing a cylindrical panorama. Cylindrical panorama construction is a simple technique with which we can construct a wide-view and high-resolution panoramic image from a collection of still images taken with a panning camera. This method, however, has a problem in that it lacks a field of view in the vertical direction. To solve this problem , we have to compute the tilting angle that is fixed during the panning. We therefore propose a method of computing the angle from images. Since our method is based on feature correspondence and a linear function, it is fast to compute. We show the effectiveness by experiments both on synthetic data and real images.
