Abstract
A multi-layer viewing system includes a stationary imager and a beam projector to project physical layer markings onto a region of an object. A headset includes an augmented reality display that is sufficiently transparent to enable a user who is wearing the headset to directly view the object through the display, and to display annotation that is superimposed on the object. A processor is configured to receive a selected location relative to the target for display of the annotation, determine an orientation of the augmented reality display by identifying images of markings in acquired images or markings on the object, calculate a display location for displaying the annotation on the augmented reality display such that the annotation is perceivable by the user as displayed at the selected position, and display the annotation at the calculated display location.
