Abstract: An augmented-reality device is used with a surveying system to guide a base station, such as a total station, during relock after loss of line of sight with a surveying instrument, such as a surveying pole with a reflective prism. A position of the surveying instrument in relation to the augmented-reality device is calculated while an object in the environment blocks line of sight from the base station to the surveying instrument. A position of the surveying instrument in relation to the environment is calculated based on the position of the surveying instrument in relation to the augmented-reality device. The position of the surveying instrument in relation to the environment is used by the base station to point toward to the surveying instrument.

Abstract: A central map can be used in a construction environment to help position devices and receive updates from devices to update the central map. Devices in the construction environment, such augmented-reality devices, laser scanners, total stations, satellite navigation receivers, and others can be used to provide “crowd-sourced” data to update the central map as the construction environment changes.

Abstract: An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.

Abstract: A camera is oriented at a workspace by comparing a three-dimensional model of the workspace to an image. A user provides an initial estimation of camera location. A feature of the three-dimensional model is projected onto the image. The feature of the three-dimensional model is compared to a corresponding feature in the image. A position and orientation of the camera are calculated by comparing the feature of the three-dimensional model the corresponding feature in the image.

Abstract: Multiple cameras are used for tool positioning, as-built documentation, and/or personnel monitoring in construction site. A camera unit comprises one or more imaging devices, a processing computer, and a communication device. The camera units are placed at multiple locations in a construction site to cover an area. The camera units are self-positioned by detecting a calibration target that moves within a working volume. The camera units can detect and calculate positions of objects, including measurement sticks, tools, personnel, etc., in the area.

Abstract: A system for surveying includes, a base station, for being positioned with respect to an environment, and an augmented-reality device. The augmented-reality device, such as a head-mounted display, has one or more cameras. An image of the base station is acquired by at least of the one or more cameras. An offset from the augmented-reality device to the base station is calculated based on the image. A position of the augmented-reality device with respect to the environment is calculated based on the offset and the base station positioned with respect to the environment. A virtual object in relation to the environment can then be presented to a user, using the augmented-reality device.

Abstract: Marking metadata during layout can be time intensive. A robotic device is used to mark out points at a construction site, and an augmented-reality device uses the points for alignment and provides metadata about the points to a user of the augmented-reality device as the user looks at the points.

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.
