Abstract: Two-dimensional targets, such as AprilTags, are used as control points. AprilTags can be used as cost effective alternatives to traditional prism targets without losing accuracy. AprilTags can be placed precisely around a construction site as “permanent” survey control points, like positioning reflector targets. A robotic total station, equipped with a camera sensor, can image the two-dimensional targets to efficiently resection itself.

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.

Abstract: A system and method for determining a position and orientation (e.g., pose) of a rigid body. The rigid body may be a position enabled projector, a surveying rod, a power tool, a drill robot, etc., in a given space. The position of the rigid body is specified by a set of three coordinates and the orientation is specified by a set of three angles. As such, based on these six values, the position and orientation of the rigid body can be determined.
