Distortion Reduction for Off-Center Perspective Projection of Panoramas [article]

Chi-Han Peng, Jiayao Zhang
2021 arXiv   pre-print
This is a key advantage in VR and virtual tour applications because it enables the user to freely"look around" in a virtual world with just a single panorama, albeit at a fixed position.  ...  We compare with other techniques that aim to augment panoramas with 3D information, including: 1) panoramas with depth information and 2) panoramas augmented with room layouts, and show that our approach  ...  Tobias et al. introduce OmniPhotos [BYLR20] for quickly and casually capturing 360°VR panoramas, and improve the visual rendering quality by alleviating distortion using a novel deformable proxy geometry  ...

360Roam: Real-Time Indoor Roaming Using Geometry-Aware 360^∘ Radiance Fields [article]

Huajian Huang, Yingshu Chen, Tianjian Zhang, Sai-Kit Yeung
2022 arXiv   pre-print
In this work, we propose 360Roam, a novel scene-level NeRF system that can synthesize images of large-scale indoor scenes in real time and support VR roaming.  ...  Our system first builds an omnidirectional neural radiance field 360NeRF from multiple input 360^∘ images.  ...  It enables quick and casual capture of high-quality 360 • panoramas with motion parallax.  ...

OmniSyn: Synthesizing 360 Videos with Wide-baseline Panoramas [article]

David Li, Yinda Zhang, Christian Häne, Danhang Tang, Amitabh Varshney, Ruofei Du
OmniSyn predicts omnidirectional depth maps using a spherical cost volume and a monocular skip connection, renders meshes in 360° images, and synthesizes intermediate views with a fusion network.  ...  Immersive maps such as Google Street View and Bing Streetside provide true-to-life views with a massive collection of panoramas.  ...  [22] develop Casual 3D photography, an algorithm which creates 5-DoF 360 • scenes from 180 • fisheye cameras.  ...
