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.
