METHOD FOR OPTICALLY SCANNING AND MEASURING AN OBJECT

摘要

In a method for optically scanning and measuring an object (O) by means of a laser scanner (10) by a procedure in which a emission light beam (18) modulated with a target frequency (?0)is emitted by means of a light emitter (17), a reception light beam (20) reflected or otherwise scattered in some way from an object (O) in the surroundings of the laser scanner (10) is received, with a measuring clock (fM), as a multiplicty of samples by means of a light receiver (21) and in each case at least the distance (d) from the object (O) is determined from the phase angles (F) of the multiplicity of samples for a plurality of measuring points (X) by means of a control and evaluation device (22), for determining the distances (d), a phase shift (?F) caused by a distace difference (?d) of temporal adjacent samples is corrected in order to correct the distances (d).
