Abstract
A method for calibrating real and virtual views includes tracking a calibration screen, wherein a real reference point, generated by a real reference point generator, is projected on the calibration screen, aligning a view of a virtual reference point to a view of the real reference point in a display, wherein the real reference point generator and the display have a fixed relative position, determining a point correspondence between the virtual reference point and the real reference point, and determining one or more parameters for rendering a virtual object in the real scene.
Claims16
An augmented reality system comprising:
- a real reference generator for displaying a real reference on a calibration screen;
- an optical see-through display having a fixed position with respect to the real reference generator;
- a virtual reference generator for displaying a virtual reference on the optical see-through display;
- an input device for aligning a view of the virtual reference with a view of the real reference through the optical see-through display, wherein the virtual reference is moved on the optical see-through display to be aligned with the view of the real reference;
- and
- a processor for determining one or more parameters for rendering a virtual object as part of a real scene seen through the optical see-through display.
A system for calibrating real and virtual views comprising:
- a real reference generator for displaying a real reference on a calibration screen;
- an optical display having a fixed position with respect to the real reference generator;
- a virtual reference generator for generating a virtual reference in the optical display, wherein the virtual reference is independently movable with respect to the real reference;
- an input device for aligning a view of the virtual reference with a view of the real reference, wherein the virtual reference is moved on the optical display with respect to the view of the real reference;
- and
- a processor for determining one or more parameters for rendering a virtual object in a real scene seen in the optical display.
