Datasets for “OmniPhotos: Casual 360° VR Photography”

This dataset contains the raw and processed data used to validate the results for the paper. Each subdirectory in the Preprocessed and Unprocessed folders contains a 360° video captured in a circle at different locations in the world, using an Insta360 One X 360° camera on a rotating selfie stick. These subdirectories are named after these locations. Both the proprietary (.insv) video format, as well as a stitched equirectangular (.mp4) video (used by our preprocessing pipeline), have been included. As well as these videos, each subdirectory contains the Input frames, used by our software to display the scene, a Capture directory that contains structure-from-motion data for the given scene, as well as a Config directory, which contains necessary configuration files to run our software. In the Preprocessed directory, the subdirectories also contain a Cache directory, containing optical flow (.floss) files, a CSV file linking the floss files to the relevant images in Input, and .obj files that contain the scene-dependent proxy mesh (deformed sphere) used to render the scene.Full details of the methodology may be found in the associated paper

The first scene in Preprocessed.zip ("Ballintoy") was missing the fitted scene-adaptive proxy geometry; this has now been added. 2. The scene "Crescent" in Unpreprocessed.zip contained an incorrect number of frames in the config file, producing a warning during preprocessing
