Abstract: A system for providing 3D surveying of an environment by an autonomous robotic vehicle comprising a SLAM unit for carrying out a simultaneous localization and mapping process, a path planning unit to determine a path to be taken by the autonomous robotic vehicle, and a lidar device. The lidar device is configured to generate the lidar data which allows the SLAM unit to receive the lidar data as part of the perception data for the SLAM process. The path planning unit is configured to determine the path to be taken by carrying out an evaluation of a further trajectory within a map of the environment in relation to an estimated point distribution map for an estimated 3D point cloud, which is provided by the lidar device on the further trajectory and projected onto the map of the environment.

Abstract: A system for 3D surveying of an environment by an unmanned ground vehicle (UGV) and an unmanned aerial vehicle (UAV) has two lidar devices. A reference unit has a first and a second marker in a spatially fixed arrangement. An automatic detection of the first marker is carried out for a coordinative measurement by the first lidar device to determine relative position data for providing relative position information of the first marker with respect to the first lidar device. The relative position data and spatial 3D information is used for an automatic detection and a coordinative measurement of the second marker by the second lidar device. The coordinative measurements are used for a referencing of lidar data of the UGV lidar device and lidar data of the UAV lidar device with respect to a common coordinate system.

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.
