Multiview Panorama Alignment and Optical Flow Refinement


Multiview Panorama Alignment and Optical Flow Refinement

Current techniques for “RealVR” experiences are usually limited to a small area around the capture setup. Simple linear blending between several viewpoints will disrupt the virtual reality (VR) experience and cause a loss of immersion for the user. To obtain smoother transitions, optical flow based warping between viewpoints can be utilized. Therefore, the panorama images of these viewpoints do not only need to be upright adjusted but also their viewing direction need to be aligned first. As panoramas for VR are usually of high resolution for high quality results in every direction, the optical flow in a high resolution is also indispensable.

This chapter gives an overview of how to align several viewpoints to a common viewing direction and obtain high resolution optical flow in between.
