A method and apparatus for aligning the left and right image channels a two-image stereoscopic three-dimensional display is disclosed. A left and right alignment pattern may be shown on the left-eye and right-eye image screens, respectively, pre-computed for any given input imaging geometry. The operator (or alignment processor) then adjust the displays to converge the superimposed left-eye and right-eye test patterns by moving the display elements using display positioning equipment and/or software. This ensures that the stereoscopic three-dimensional display geometry matches the three-dimensional camera imaging geometry in order to produce a minimally-distorted visual depth perception of objects in space. Such precision alignment can be essential for efficient and safe telerobotic operation applications, as in the case of remote aerial refueling operations, for example.
