Abstract
A method of aligning reference frames for an augmented reality display is provided. The method comprises receiving three or more target images positioned at predefined physical reference points in a specified physical space, wherein the physical reference points are part of a reference frame of the physical space. Distances between the physical reference points of the target images are calculated and compared with distances between virtual reference points comprising a reference frame of a three-dimensional virtual model to create a number of distance comparisons. The physical reference points are correlated with virtual reference points according to the distance comparisons. The reference frame of the physical space is then aligned with the reference frame of the three-dimensional virtual model according to the correlation of the physical reference points and virtual reference points.
