Abstract
The invention relates to a method for registering surfaces, using a scanner system comprising a radiation source for emitting electromagnetic radiation (ES), a scanning device for guiding the radiation over the surface in order to scan the latter and a receiver for receiving the radiation (RS) that is reflected by the surface. According to the invention, the radiation is spectrally separated to analyse the surface characteristics and a distance measuring unit is used to derive distance information in parallel from the received radiation.

19. A scanner system for registering and surveying surface topographies, comprising:
-
one radiation source for emitting electromagnetic radiation; one scanning device for guiding the radiation over the surface in order to scan the surface; and one receiver unit for receiving the radiation reflected by the surface, the receiver unit comprising a distance-measuring device that measures distance based on a pulse transit time or phase measurement method for deriving distance information from the radiation received, wherein the radiation source and the receiver unit are formed and tuned to one another in such a way that spectral separation of the radiation takes place. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method for registering surfaces by means of a scanner system, comprising the acts:
-
emitting electromagnetic radiation; receiving radiation after reflection by the surface; analyzing the radiation received; repeating the emitting, receiving and analyzing acts several times during scanning of the surface; and deriving distance information based on the analysis of the radiation, wherein the analysis of the radiation is effected with spectral separation of the radiation. - View Dependent Claims (39, 40, 41)
