Abstract
A method of determining a calibration parameter for a three-dimensional (3D) display device includes determining a calibration parameter for a 3D display device based on an image of a second pattern three-dimensionally converted from an image of a first pattern.
Claims42
A method of determining a calibration parameter for a three-dimensional (3D) display device, the method comprising:
- acquiring an image of a first pattern output through a panel and an optical layer as an image of a second pattern;
- and
- determining the calibration parameter for the 3D display device based on a parameter corresponding to a period of the first pattern, a parameter corresponding to a gradient of the second pattern, and a parameter corresponding to a period of the second pattern,
- wherein the parameter corresponding to the period of the first pattern is an interval between lines included in the first pattern, and
- wherein the determining comprises calculating a rotation angle θ between the optical layer and the panel and a pitch p of the optical layer based on relations between the rotation angle θ and the pitch p, the relations comprising:
- a first relation between the rotation angle θ and the pitch p being based on the parameter corresponding to the period of the first pattern and the parameter corresponding to the gradient of the second pattern;
- and
- a second relation between the rotation angle θ and the pitch p being based on the parameter corresponding to the period of the second pattern.
