Classification: CPC G  H | IPC G

Claim 7:
8. A non-transitory computer-readable medium storing instructions comprising:
one or more instructions that, when executed by one or more processors, cause the one or more processors to:
generate a transformation function to provide a mapping between three-dimensional points in a real-world coordinate system to three-dimensional points in a display coordinate system corresponding to a three-dimensional display space of an optical see-through head-mounted display device based on a set of measurements gathered using a positional tracking device;
apply the transformation function to a first internal projection operator to produce a first corrected projection operator that the optical see-through head-mounted display device uses to display a first two-dimensional perspective image for a left eye;
apply the transformation function to a second internal projection operator to produce a second corrected projection operator that the optical see-through head-mounted display device uses to display a second two-dimensional perspective image for a right eye; and
display, via the optical see-through head-mounted display device, a three-dimensional image in the display coordinate system by presenting the first two-dimensional perspective image based on the first corrected projection operator and presenting the second two-dimensional perspective image based on the second corrected projection operator,
wherein the three-dimensional image in the display coordinate system is superimposed on an object in the real-world coordinate system.
