Abstract
A virtual image is registered among a perceived real world
background. Tracking light is scanned into the real world
environment, which includes at least one detector pair. A
first time and a second time at which the tracking light
impinges on the first detector is detected, in which the first
time and second time occurs within adjacent scan lines. A
time at which a horizontal scan line edge (e.g., beginning of
scan line or end of scan line) is encountered is derived as
occurring one half way between the first time and the second
time. The horizontal location of the first detector then is
determined within a specific scan line inferring the scan line
edge time. The vertical location of the detector is determined
within a scan frame by measuring time duration using the
beginning of the frame. By determining a location independently
from the temporal resolution of the augmented imaging
system, the temporal location of the detector is identified
to a sub-pixel/sub-line precision. The augmented image is
registered either to a 3D real world spatial coordinate system
or to a time domain coordinate system based upon tracked
position and orientation of the user.
