Abstract: In a method for capturing three-dimensional data of an area of space, a plurality of measuring beams (Ls) are sent out to a plurality of measuring points. A detector (50) receives a plurality of reflected beams (Lr) which are reflected by the measuring points (34a). A plurality of distances to the measuring points (34a, 34b) are determined as a function of the reflected beams (Lr). According to one aspect of the invention, at least one object (30) which comprises a hidden channel (66) having a visible entry opening (72) is located in the area of space. A rod-shaped element (32) is inserted into the channel (66) in such a manner that a free end (70) protrudes from the entry opening (72). A first distance to a first measuring point (34a) and a second distance to a second measuring point (34b) are determined. An orientation (74) of the hidden channel (66) is determined as a function of the first and the second distances.

Abstract: A laser scanner may include a measuring head structured to be rotatable around a first axis, a first rotary drive structured to rotate the measuring head, a rotary mirror rotatable around a second axis, a second rotary drive structured to rotate the rotary mirror, a transmitter structured to transmit a light beam, a receiver structured to receive a reflection of the light beam from an object located at a distance from the laser scanner, and a processor structured to process signals embedded within the reflection of the light beam. The measuring head may include a plurality of modules, and the first rotary drive, rotary mirror, second rotary drive, transmitter, and receiver may be provided on one of the plurality of modules. At least two of the plurality of modules may be releasably connected to each other.

Abstract: A laser scanner has a first axis and a second axis extending essentially transversely to the first axis. A measuring head is adapted to be rotated about the first axis. The measuring head has at least a first, a second, and a third module, wherein at least the first module and the third module are releasably connected to each other. A first rotary drive for rotating said measuring head is comprised within the first and the second modules. A rotary mirror is adapted to be rotated about the second axis. The rotary mirror is comprised within the third module. A second rotary drive is provided for rotating the rotary mirror. The second drive is likewise comprised within the third module. A transmitter is provided in the measuring head for transmitting a light beam. A receiver is provided in the measuring head for receiving the light beam after a reflection thereof by an object located at a distance from the laser scanner.

Abstract: A laser scanner for optically scanning and measuring an environment comprises a light transmitter having a predetermined transmission power for emitting a light beam. The emitted light beam is reflected at a measurement point in the environment. The reflected light beam is received with a certain intensity by a receiver. The transmission power is adjustable as a function of the intensity of the reflected light beam. Furthermore, a gray-scale value of the measurement point is determined as a function of the transmission power adjusted.
