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 that resulted in the best aligned virtual object are deemed the final calibration matrix to be used with the OST HMD.

HMD calibration with direct geometric modeling

A virtual image display device configuring a display device includes a display section configured to display an image while enabling visual recognition of an outside scene. The virtual image display device includes an image pickup section configured to pickup an image in an image pickup range that overlaps a range visually recognized through the display section. The virtual image display device includes a coupling section including at least one movable section and configured to couple the image pickup section to the display section. The display device is capable of acquiring a motion amount in the movable section with a control section.
