Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
