  • Publication number: 20240060774
    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.

  • Patent number: 11869159
    Abstract: A laser scanner is used with a mixed reality device to track and/or locate objects in an environment, such as a construction site. In some configurations, mixed reality is used to assist laser scanning. A collection of data points representing a point cloud can be acquired with a laser scanner. A reference frame of a mixed-reality device is aligned to the data of the point cloud. A graphic is presented on a display of the mixed-reality device. The graphic is positioned on the display in relation to the environment, based on the reference frame of the mixed-reality device being aligned to data of the point cloud. An item in the environment is tracked (e.g., a hazard or a tool). Data is provided to the mixed-reality device regarding a position of the item in the environment.

  • Patent number: 11821730
    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.

  • Publication number: 20230351541
    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.

  • Patent number: 11373381
    Abstract: A system for integrating high-density laser scanner data with mixed-reality is disclosed. In some implementations, the system may acquire, using a laser scanner, a collection of data points representing a three-dimensional point cloud, wherein the laser scanner includes: a laser configured to generate an optical beam; a beam-steering device configured to steer the optical beam; and a detector configured to receive light from the optical beam, after light from the optical beam is reflected from an object in an environment. The system may transmit data of the point cloud to the augmented-reality device, wherein the augmented-reality device comprises: one or more cameras configured to acquire images of the environment; and a display configured to render graphics on the display. The system may align a reference frame of the augmented-reality device to the data of the point cloud.

  • Patent number: 11181991
    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.

  • Patent number: 11002541
    Abstract: A Position and Orientation Measurement Engine (POME) is a mobile camera system that can be used for accurate indoor measurement (e.g., at a construction site). The POME uses a plurality of cameras to acquire images of a plurality of targets. If locations of the plurality of targets are precisely known, images of the targets can be used to determine a position of the POME in relation to the plurality of targets. However, to precisely determine locations of the plurality of targets can be time consuming and/or use expensive equipment. This disclosure discusses how to use a camera system with an electronic distance measuring unit to determine locations of the plurality of targets.

  • Publication number: 20200151848
    Abstract: A system and method for surface profiling via a projection system, such as a position enabled projector. By way of example, a three-dimensional representation of a physical object, such as an uneven surface of the object, may be generated and profiled. The three-dimensional representation may be a 3D point cloud, a surface mesh, or any other suitable type of representation. A two-dimensional image to be projected onto the surface may undergo an image transformation based on the generated 3D representation of the surface. The transformed image is then projected onto the surface, where the image points projected are at their true positions with true scale. Moreover, the projected image may be automatically updated when the projector is moved to a new position.

  • Patent number: 10646975
    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.
