3. TWO CAMERAS AND STRUCTURED LIGHT 
SOURCE 
This device uses the principle of an image - the correlation. The 
image projector sends the structured light on the object and the 
object is recorded by using of two CCD cameras from a known 
basis. This system can by combined with rotating platform for 
complete documentation of object (0-360deg). Every image pair 
must be post-processed by using image con-elation for 3D co 
ordinates of object points determination. 
4. LASER SCANNER HEAD SICK 
In autumn 2002 a small inexpensive laser 3D scanner based on 
“time of flight” was developed. The laser head SICK is the 
main part of 3D scanner. There are two possibilities for its use: 
the first one as a linear laser scanner (on Fig. 3) and the second 
one as a rotating head (Fig.4). In the linear scheme the SICK 
head was used as a 3D scanner for sculpture documentation, but 
the resolution on about 50cm was not very high (it is a good 
idea for more precision scanners). Next, the head was 
completed with a motorised PC- controlled rotating part with 
incremental device for angle measurement. It is a ’’classical” 
laser scanner scheme. All the control software was made at the 
CTU Prague and it will be used as a “school laser scanner”.
