First Claim
1. A method for embedding calibration metadata, comprising:
- capturing a sequence of stereoscopic images by a plurality of image sensors of a stereoscopic video rerecording device;
combining the captured sequence of stereoscopic images into a stereoscopic video sequence; and
embedding calibration information into the stereoscopic video sequence in a real time as the sequence of stereoscopic images is being recorded.

Abstract
Embodiments are disclosed for embedding calibration metadata for a stereoscopic video capturing device. The device captures a sequence of stereoscopic images by a plurality of image sensors and combines the captured sequence of stereoscopic images into a stereoscopic video sequence. The device further embeds calibration information into the stereoscopic video sequence in a real time as the sequence of stereoscopic images is being recorded. The calibration information can be used to correct distortion caused by hardware variances of individual video capturing devices. The corrected stereoscopic videos can be used to provide a virtual reality (VR) experience by immersing a user in a simulated environment.

15. A method for rendering a stereoscopic video sequence using calibration metadata, comprising:
-
receiving a stereoscopic video sequence including a sequence of stereoscopic images by a stereoscopic video playback device; extracting calibration information from the stereoscopic video sequence; for each display pixel of the stereoscopic video playback device, identifying a corresponding image pixel of the stereoscopic video sequence using the calibration information; and rendering a stereoscopic video on a stereoscopic display of the stereoscopic video playback device by projecting contents of corresponding image pixels of the stereoscopic video sequence to the display pixels of the stereoscopic video playback device. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for generating a virtual reality (VR) using 360-degree stereoscopic videos, comprising:
-
receiving a plurality of stereoscopic video sequences, each of the stereoscopic video sequences including a wide-angle left channel video and a wide-angle right channel video; extracting calibration information from the stereoscopic video sequences; applying the calibration information to frames of the stereoscopic video sequences to correct distortion caused by capturing devices of the stereoscopic video sequences; projecting frames of the stereoscopic video sequences from spherical forms to rectangular forms; and stitching frames from wide-angle left channel videos into 360-degree frames of a left channel of a 360-degree VR stereoscopic video, and stitching frames from wide-angle right channel videos into 360-degree frames of a right channel of the 360-degree VR stereoscopic video. - View Dependent Claims (26, 27, 28, 29)
