Abstract
The present disclosure relates to a method for calibrating a projector. In one example, the method includes receiving by a processing element light field data corresponding to a calibration image projected by a projector and captured by a light field capturing device, and modeling by a processing element one or more intrinsic properties of the projector using the light field data and the calibration image. The calibration image may be projected by the projector directly into the light field capturing device.
Claims16
A method of calibrating a projector, the method comprising:
- receiving by a processing element light field data corresponding to a calibration image captured by a light field capturing device, wherein the calibration image is projected by a projector directly into a light field capturing device;
- estimating by the processing element directions of light rays emitted by the projector when projecting the calibration image by utilizing light ray data;
- and
- modeling by a processing element one or more intrinsic properties of the projector using the light field data and the calibration image.
(canceled)
A system for calibrating a projector, the system comprising:
- a projector configured to project a calibration image;
- a light field capturing device configured to capture at least a portion of the calibration image projected by the projector, wherein light rays making up the calibration image are projected into the light field capturing device without reflecting on an intermediate surface;
- and
- a processing element in communication with the light field capturing device, wherein the processing element is configured to:
- estimate directions of light rays emitted by the projector when projecting the calibration image by utilizing ray data;
- transform the ray representations to a simplified model;
- and
- mode one or more intrinsic properties of the projector using light field data corresponding to the calibration image captured by the light field capturing device.
