The method involves performing laser scanning of two sets of positions and locations to generate two three-dimensional images of a surrounding area (17), respectively. The two sets of positions and locations are measured by an inertial measurement unit (IM...

The device has a laser distance measuring device with a laser transmitter for transmitting radiations to a target, and a laser receiving device for receiving the radiations reflected from the target. An analyzing device measures delay time of the radiation...

An optical system (OS) (10) for a transmitter (9) and an OS (13) for a receiver (14) focus on a target in an object area to minimize striking area of a transmission beam (15) on the target. An upper measuring head part (1b) swivels around a vertical axis (...

Arrangement comprises a laser distance meter and a scanning unit for scanning the object space. A passive optoelectronic receiver (17) is provided for use with the scanning unit (8) and scanning unit and distance meter are scanned synchronously so that a m...
