Innovations in the development of laser and optic rotating scanner LORS
Koska, Bronislav, Jiri Pospisil and martin Striner
The paper presents information about the significantly innovated version of the laser and optical rotation LORS scanner and about the new system LORS2, which arose by changes in configuration of the original system. LORS started to be developed in 2002 within a grant project on the basis of in its time original concept. One of demands on the system was a lower price than for the commercial scanning systems. The basic system components of the original version stayed preserved. It is a digital camera, a laser plane and a rotating platform. The measured object is placed on the rotating platform through which a vertically orientated laser plane goes. A suitably placed digital camera reads trail position. On the basis of knowledge of geometric parameters of all system components and of trail image coordinates it is possible to calculate 3D point coordinates on the object surface. A digital reflex camera Canon E350D with high resolution 8 MPixels, fast USB 2 connection and with possibility of developing the own operating software with the aid of the original Remote Control Software Development Kit (RC-SDK) is used in the new version. An exact step motor operated from a control card, which is connected to the computer by a serial port, is newly used for drive of the rotating platform. A worm gearing with gear ration 60:1 is used for making possible smaller steps. The both new components enable fully automatic work of the LORS system.
