PROBLEM TO BE SOLVED: To provide a system and a method for simplifying calibration of an AR system with respect to a real world scene.SOLUTION: An optical see-through (OST) head-mounted display (HMD) uses a calibration matrix having a fixed sub-set of adjustable parameters within all its parameters. Initial values for the calibration matrix are based on a model head. A predefined set of incremental adjustment values is provided for each adjustable parameter. During calibration, the calibration matrix is cycled through its predefined incremental parameter changes, and a virtual object is projected for each incremental change. The resultant projected virtual object is aligned to a reference real object, and the projected virtual object having the best alignment is identified. The setting values of the calibration matrix are deemed the final calibration matrix.SELECTED DRAWING: Figure 26A |
