1. A system for aligning an augmented-reality device with an environment, the system comprising:
a visual design comprising an arrangement of lines or shapes, the visual design configured to be supported by a surveying rod at a known fixed offset from a device coupled with the surveying rod, wherein the device coupled with the surveying rod is part of a surveying system and is different than the augmented-reality device;
the augmented-reality device, wherein the augmented-reality device comprises a camera; and
one or more processors configured to:
receive a position of the device coupled with the surveying rod in relation to a device comprising a laser,
measure a position of the visual design in relation to the augmented-reality device, based on an image of the visual design acquired by the camera of the augmented-reality device; and
align a coordinate system of the augmented-reality device with respect to the environment, based on the position of the device coupled with the surveying rod in relation to the device comprising the laser, the position of the visual design in relation to the augmented-reality device, and the known fixed offset of the visual design from the device coupled with the surveying rod.
