CAMERA How can we convert stereo 360 video to 6DoF for more comfortable VR?

Benjamin Attal, Selena Ling, Aaron Gokaslan, Christian Richardt, and James Tompkin’s paper ‘MatryODShka: Real-time 6DoF VideoView Synthesis using Multi-Sphere Images’ was presented at last month’s European Conference on Computer Vision (ECCV) 2020.


We introduce a method to convert stereo 360° (omnidirectional stereo) imagery into a layered, multi-sphere image representation for six degree-of-freedom (6DoF) rendering. Stereo 360° imagery can be captured from multi-camera systems for virtual reality (VR), but lacks motion parallax and correct-in-all-directions disparity cues. Together, these can quickly lead to VR sickness when viewing content. One solution is to try and generate a format suitable for 6DoF rendering, such as by estimating depth. However, this raises questions as to how to handle disoccluded regions in dynamic scenes. Our approach is to simultaneously learn depth and disocclusions via a multi-sphere image representation, which can be rendered with correct 6DoF disparity and motion parallax in VR. This significantly improves comfort for the viewer, and can be inferred and rendered in real time on modern GPU hardware. Together, these move towards making VR video a more comfortable immersive medium.
