Abstract

Arrangement for positioning a bore crown 1 in a positioning plane 2. A bore rig 3 is provided with two video cameras 9 for detecting the position of a light source 8 next to the bore crown. The video cameras are oriented in parallel. The viewing fields of the video cameras are offset in relation to each other in such a way that the light source gives two points 20, 21 on a monitor 10 common to the two cameras if the light source is situated outside the positioning plane, and one point 11 if the light source is situated in the positioning plane. <IMAGE>
