Although stereoscopic panoramas promise an inviting, immersive experience for viewers, at high resolutions distortions can develop that make viewing unpleasant or intolerable. Disney researchers have developed methods to correct these problems, yielding high-quality panoramas at megapixel resolutions.
The problems occur when left eye/right eye parallax views are introduced in a panorama to create the impression of depth. The Disney researchers developed methods for correcting the optical distortion of the wide-angle lenses, as well as correcting less-than-perfect camera orientations.
"Simply capturing more and higher resolution images usually isn't feasible and, more importantly, doesn't fully resolve the issues," says Disney researcher Alexander Sorkine-Hornung.
To offset the root problem, the team devised an optical flow-based upsampling method, which interpolates what light rays are missing in between.
The researchers found that their techniques for correcting problems in 360-degree stereo panoramas were robust and could apply to other kinds of panoramas, such as linear panoramas where the camera is mounted on a car or otherwise moves in a straight line.
