Runtime Baseline Adjustment for Stereo Panorama

A stereo panorama consists of a pair of panoramic images, where one panorama is for the left eye, and the other panorama is for the right eye. The disparity between two panoramas provides parallax which enables stereo sense to the viewer. A stereo panoramic pair provides a stereo sensation up to a full 360 degrees. A typical stereo panorama can be created by mosaicing images from a rotating camera. However, the conventional image mosaicing process is often done offline. And once the mosaicing stage is finished, the disparity between two panoramas is fixed, which means that the baseline between two eyes cannot be changed. In order to support a dynamic baseline, the mosaicing process should be performed in run-time. In the paper, we discuss the theory of stereo sensation, and the algorithm of carrying out runtime panorama image mosaicing to support baseline change and parallax real-time adjustment.
