Abstract
A device for position determination of measuring points of a measuring object comprises a measuring means for determining the position of the measuring points relative to the position of the measuring means and a reference measuring means for determining the position of the measuring means relative to a reference system. The reference measuring means comprises a measuring arm or a robot arm, the proximal end of which is fixed with respect to the reference system, and the measuring means comprises an optical sensor means disposed at the distal end of the measuring arm or robot arm. The optical sensor means comprises at least two single or multiple image sensors which record images of at least part of the measuring object. A processing means determines the position of the measuring points of the measuring object from the recorded images. The processing of the recorded images is effected at least as rapidly as the recording frequency of the single and multiple image sensors, in real time (real time processing).
