Disclosed are techniques for displaying AR elements on a display system of a construction machine. A position of the construction machine in a world reference frame is detected. An orientation of the construction machine is detected. A position of an operator of the construction machine in a machine reference frame is detected. A position of the operator in the world reference frame is determined based on the position of the operator in the machine reference frame, the position of the construction machine in the world reference frame, and the orientation of the construction machine. The AR elements are generated based on the position of the operator in the world reference frame and a position of the display system in the world reference frame. The AR elements are then displayed on the display system.

High-accuracy augmented reality display for construction machines

Techniques for occluding displayable content on a portable electronic device. An EDM device of the portable electronic device may capture a world distance map comprising a plurality of distances to a plurality of points. A camera of the portable electronic device may capture a camera image containing the plurality of points. A geospatial position of a GNSS receiver may be detected. A geospatial position of the camera may be calculated based on the geospatial position of the GNSS receiver. An angle sensor may detect an orientation of the camera. A model image may be generated based on a 3D model, the orientation of the camera, and the geospatial position of the camera. The model image and/or the camera image may be occluded based on the world distance map and the 3D model. A superimposed image comprising the camera image and the model image may be generated and displayed.

Augmented reality image occlusion

Techniques for calculating a geospatial position of a point of interest using a portable electronic device. A camera of the portable electronic device may observe the point of interest. An EDM device of the portable electronic device may capture a distance to the point of interest. An angle sensor may detect an orientation of the EDM device. A geospatial position of a GNSS receiver of the portable electronic device may be detected. A geospatial position of the EDM device may be calculated based on the geospatial position of the GNSS receiver. The geospatial position of the point of interest may be calculated based on the geospatial position of the EDM device, the orientation of the EDM device, and the distance to the point of interest.

Augmented reality distance measurement

A method for positioning an augmented reality (AR) model of a building or area of construction relative to an image of the building or area of construction as displayed on a handheld device. The AR model is positioned so that vertical surfaces of the AR model are aligned with vertical surfaces of the building or area of construction and a horizontal surface of the AR model is aligned with an associated horizontal surface of the building or area of construction.

Accurately positioning augmented reality models within images

Methods for displaying an augmented reality (AR) model on an AR device are disclosed. Alignment between a geospatial reference frame and an AR reference frame is monitored and adjusted to improve placement of the AR model displayed on the AR device.

Methods of displaying an augmented reality model on an augmented reality device

Techniques for displaying underground assets using a portable electronic device. A camera image of a ground having a ground surface may be captured. A placement of a virtual pit in the camera image may be determined. A pit view comprising the virtual pit and a virtual representation of an underground asset, and a superimposed image comprising the camera image and the pit view may be generated. A top opening of the virtual pit may align with the ground surface in the camera image. A portion of the virtual representation of the underground asset may be shown inside the virtual pit and below the top opening of the virtual pit such that a distance between the top opening and the portion of the virtual representation of the underground asset inside the virtual pit may provide a visual indication of a depth of the underground asset relative to the ground surface.

Creating improved 3D models from 2D data

A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.
