Abstract:
Camera and/or lens calibration information is generated as part of a calibration process in video systems including 3-dimensional (3D) immersive content systems. The calibration information can be used to correct for distortions associated with the source camera and/or lens. A calibration profile can include information sufficient to allow the system to correct for camera and/or lens distortion/variation. This can be accomplished by capturing a calibration image of a physical 3D object corresponding to the simulated 3D environment, and creating the calibration profile by processing the calibration image. The calibration profile can then be used to project the source content directly into the 3D viewing space while also accounting for distortion/variation, and without first translating into an intermediate space (e.g., a rectilinear space) to account for lens distortion.

Claim (Index 6):
A method of generating camera calibration information for use in displaying immersive content, comprising:\n receiving first digital image data corresponding to a first image captured using a digital video camera and a wide angle lens, the first image taken of a three-dimensional (3D) object having a plurality of markers distributed thereon; accessing a 3D digital model corresponding to the 3D object, the 3D digital model having a two-dimensional (2D) texture map associated therewith that corresponds to a 3D surface of the 3D digital model; identifying a plurality of pixel groups in the first image data using a processor, where each pixel group of the plurality of pixel groups includes one or more pixels of the first image data that correspond to a different one of the plurality of markers; and generating, using a processor, a mapping between the identified pixel groups and the 2D texture map corresponding to the 3D surface, the mapping usable for calibrating second digital image data for display in a simulated 3D viewing environment.
