    Abstract: A Method for generating scaled terrain information while operating a bulldozer. The bulldozer may include a driving unit comprising a set of drive wheels, a motor connected to at least one of the drive wheels, a blade for altering the surface of the terrain, at least one camera for capturing images of the environment, the camera being positioned and aligned in a known manner relative to the bulldozer, and a controlling and processing unit. A method may include moving the bulldozer while concurrently generating a set of image data by capturing an image series of terrain sections with the at least one camera so that at least two images of the image series cover an amount of identical points in the terrain, and either applying a simultaneous localisation and mapping (SLAM) algorithm or a stereo photogrammetry algorithm to the set of image data and thereby deriving terrain data.

    Abstract: A laser projection system for projecting an image on a workpiece includes a photogrammetry assembly and a laser projector, each communicating with a computer. The photogrammetry assembly includes a first camera for scanning the workpiece, and the laser projector projects a laser image to arbitrary locations. Light is conveyed from the direction of the workpiece to the photogrammetry assembly. The photogrammetry assembly signals the coordinates light conveyed toward the photogrammetry assembly to the computer with the computer being programmable for determining a geometric location of the laser image. The computer establishes a geometric correlation between the photogrammetry assembly, the laser projector, and the workpiece for realigning the laser image to a corrected geometric location relative to the workpiece.

    Abstract: Embodiments relate to selecting textures for a user-supplied photographic image in image-based three-dimensional modeling. In a first embodiment, a computer-implemented method includes a method positioning a geographic structure using user-supplied photographic images of a geographic structure. In the method, a user-supplied photographic images inputted by a user are received. Embedded camera parameters that specify a position of the cameras when each user-supplied photographic image was taken and are embedded in each user-supplied photographic image are read. An estimated location of the geographic structure is automatically determined based on the embedded camera parameters in each user-supplied photographic image. Each user-supplied photographic image to be texture mapped to the three-dimensional model is enabled.

    Abstract: An approach is provided for pole extraction from optical imagery. The approach involves, for instance, processing a plurality of images using a machine learning model to generate a plurality of redundant observations of a pole-like object and/or their semantic keypoints respectively depicted in the plurality of images. The approach also involves performing a photogrammetric triangulation of the plurality of redundant observations to determine three-dimensional coordinate data of the pole-like object and/or their semantic keypoints. The approach further involves providing the three-dimensional coordinate data of the pole-like object as an output.
