Abstract: A method for generating a 3D combined model that represents a scene includes acquiring the coordinates in an external geodetic frame, acquiring at least one 3D primary model representing the scene, which model includes primary model elements, oriented in the geodetic frame. The primary model elements are assigned measured primary physical property values in the form of coordinates in a local three-dimensional coordinate system of the corresponding point. The method further includes generating a 3D secondary model representing the scene, wherein at least some secondary model elements are assigned coordinates in the local coordinate system and at least one secondary physical property value. At least some secondary model elements are assigned coordinates in the external geodetic frame. The primary and at least one secondary model are then combined. Also disclosed are a related system and reference members for use in the system.

Abstract: A repair welding segment detection method includes generating, based on a result of the inspection determination, shape mismatch data obtained by extracting a shape mismatch portion of the weld bead, dividing the shape mismatch data into N. where N is an integer of 2 or more, equally divided windows in a direction perpendicular to a welding direction of the weld bead, setting a shift region formed by i, where i: an integer of 1 or more, continuous windows among the N windows, separately calculating volumes of (N-i+1) shift regions obtained by shifting one by one the i windows forming the shift region in the welding direction, and determining that a shift region having a volume of a predetermined value or more among the calculated volumes of the (N-i+1) respective shift regions is a defective segment of the weld bead.

Abstract: An apparatus includes a display screen that includes OLED pixels disposed at a particular pitch in a first plane. A light projector includes light emitting elements disposed in a second plane parallel to the first plane. The light emitting elements are disposed at the same pitch as the OLED pixels or at an integer multiple of the pitch of the plurality of OLED pixels. The light emitting elements are operable to produce light at a wavelength for transmission through the display screen, and the first and second planes are separated from one another by a distance D such that d2=2*(λ)*(D)/(N), where d is the pitch of the OLED pixels, λ is the wavelength, and N is a positive integer.

Abstract: A bridge military load classification (MLC) assessment system may increase soldier survivability and/or engineer reconnaissance support to military decision-making process (MDMP) while reducing the required operator level of expertise. A set of “at distance” 3D dimensioning solutions may include soldier-guided, vector-based measurements, photogrammetry, and/or computer vision (CV) and augmented reality (AR) methodologies-enabling off image plane measurements along all three axes across the image through the image principal point. The solutions may include (1) single image with view of bridge feature that introduces two- or three-point perspective, (2) camera focal length, (3) camera sensor width, (4) laser rangefinder (LRF) vector to the image principal point, and (5) two lines traced along edges of the bridge to identify one vanishing point. A rapid MLC could be calculated from a considerable distance (greater than 100 meters) given an unobstructed “below-deck” view of the bridge.
