Due to the rapid development on hardware and camera technologies, panoramic images have become widely accessible and they have many advantages in supporting the 3D reconstruction tasks. In this paper, we have proposed an automatic image registration approach to determine the spatial relationship among a large set of ground-level panoramic images and an orthogonal aerial image. We have also developed a method to automatically extract and rectify the building textures from the panoramic images for texture mapping in 3D city models.
