摘要: A laser scanner and a system with a laser scanner for measuring an environment. The laser scanner includes an optical distance measuring device, a support, a beam steering unit rotatably fixed to the support which rotates around a beam axis of rotation. The beam steering unit includes a mirrored surface which deflects radiation used in the optical distance measurement and an angle encoder for recording angle data. The optical distance measurement is performed by a progressive rotation of the beam steering unit about the beam axis of rotation and the continuous emission of a distance measurement radiation, the emission being made through an outlet area arranged in the direction of the mirrored surface on the support, the receiving optics for receiving radiation are arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.

摘要: A reality capture device configured to perform a measuring process for generating a digital representation of an environment comprising a body defining a first axis, and an imaging unit with one or more 2D cameras configured to provide 2D image data of the environment. The device comprises a ToF camera arrangement configured for capturing 3D point-cloud data of the environment and comprising at least two time-of-flight cameras, wherein each time-of-flight camera comprises a sensor array and one or more laser emitters, the sensor array of each of the time-of-flight cameras having an optical axis and being configured to receive reflections of light pulses emitted by the one or more laser emitters of the respective time-of-flight camera, the time-of-flight cameras being arranged around the first axis so that each sensor array has one or two other sensor arrays as a neighbouring sensor array.

摘要: A laser scanner device can be adapted to be mounted to a vehicle, the device comprising a LiDAR module working based on a laser measuring beam and time-of-flight-measurement-principle. The LiDAR module is configured to provide a horizontal field of view of at least 60°, an instantaneous vertical field of view of at least ±2°, a scan resolution of at least one point per 0.8° in horizontal and vertical direction, and a frame rate of at least 10 Hz for scanning at least the entire horizontal and instantaneous vertical field of view with said scan resolution, wherein the LiDAR module comprises a multibeam transmitter configured for generating a plurality of measuring beams.

摘要: A reality capture device for generating a digital three-dimensional representation of an environment enables an object within an infrastructure to be surveyed or detected. The reality capture device is compact and easy to use, allowing for fast and reliable capture. The reality capture device can be carried and moved by a mobile carrier, particularly a person, robot or vehicle, and can be moved during a measuring process for generating a digital representation of an environment. The mobile reality capture device includes a localization unit for providing a simultaneous localization and mapping functionality, a laser scanner, and a camera unit. The mobile reality capture device is configured to be carried by a user through the room. The room is surveyed during the movement of the mobile reality capture device. The data from the laser scanner and the camera unit are referenced to each other by means of the localization unit.
