Abstract: A construction machine comprising a chassis, a steering, and a powertrain for driving the construction machine by the chassis, an earth-moving tool for working a terrain, and a measuring system having a first measuring unit configured for generating first measuring data in a first detection range and comprising at least a first camera and a first LiDAR scanner configured for rotating a first measuring beam around a first axis and around a second axis non-parallel to the first axis with a rotating speed of at least 0.5 Hz with respect to each axis, an interface connecting the first measuring unit to a computer configured for, based on the first measuring data, at least one of generating a three-dimensional model of the terrain within the first detection range, identifying an obstacle or a person within the first detection range, and controlling the steering, the powertrain, and/or the earth-moving tool.

Abstract: A pose tracking system for continuously determining a pose of a digital video camera while filming a scene at a set of a film or TV production, wherein the system comprises a pose tracking device that comprises 2D cameras configured to provide 2D image data of an environment and at least one time-of-flight camera comprising a sensor array and one or more laser emitters, wherein the pose tracking device is attached to or configured to be attached to the digital video camera so that the ToF camera is oriented to capture 3D point-cloud data of the scene filmed by the digital video camera, wherein the pose tracking device comprises a localization unit.
