1. A method of calibrating an optical see-through display, comprising the steps of:
- (a) repeating the steps of;
(i) receiving an input from a user indicating that the user has aligned an augmented reality (AR) marker with an object on the optical see-through display; and
(ii) obtaining a pose matrix based upon the user'"'"'s alignment of the AR marker with the object; and
(b) computing a calibrated projection matrix for calibration of the optical see-through display based upon a plurality of pose matrices.

Abstract
Two-dimensional or three-dimensional augmented reality (AR) markers are provided for alignment with a target object in calibrating an optical see-through display, such as a head-mounted display (HMD), in an AR system. A calibrated projection matrix for calibration of the optical see-through display is computed based upon a user'"'"'s repeated alignments of the AR markers with the target object.

11. An apparatus configured to perform operations to calibrate an optical see-through display, the apparatus comprising:
-
a memory; and a processor for executing a set of instructions stored in the memory, the set of instructions for; (a) repeating n times, n being more than one, and each loop in which steps are repeated is an ith loop, i being less than or equal to n, the steps of; (i) receiving an input from a user indicating that the user has aligned an augmented reality (AR) marker with an object on the optical see-through display; and (ii) obtaining an ith pose matrix based upon the user'"'"'s alignment of the AR marker with the object; and (b) computing a calibrated projection matrix for calibration of the optical see-through display based upon n pose matrices. - View Dependent Claims (12, 13, 14, 15, 16, 17)
