Summary and future work

After giving a short survey on image-based rendering techniques, a method to warp cylindrical panoramas with the use of the OpenGL graphic system was presented. With this approach fast warping of high resolution images can be done on personal computers with consumer OpenGL hardware.

A possible extension of the presented work would be the display of stereo panoramas to give the user a realistic sense of depth. In [HH98] a system is described which is capable to record stereo panoramas. The method uses two cameras and corrects discrepancies of the epipolar geometry or image differences automatically. As a result one gets two cylindrical panoramic images. They could be used directly for the technique described in this article. For that purpose the left eye and the right eye should see different textures of the cylinder. For example this could be achieved with LCD shutter glasses.
