Abstract
An augmented-reality device is aligned with an environment using a correction source. A position of a reflector (or other device that is part of a surveying system) coupled with a surveying rod is measured in relation to a correction. A position of a visual design, which is coupled with the surveying rod, is measured in relation to an augmented-reality device, based on an image of the visual design acquired by the augmented-reality device. A coordinate system of the augmented-reality device is aligned with the environment based on the position of the reflector in relation to the correction source, the position of the visual design in relation to the augmented-reality device, and an offset between the reflector and visual design.
